"In a milestone for energy storage technology, Peak Energy has selected Sacramento, California, as the home of America's first manufacturing facility dedicated to grid-scale sodium-ion battery systems," according to the sustainability news site Intelligent Living. The move "represents the first large-scale test of whether sodium-ion technology can deliver on its promise of cheaper, safer, and more sustainable grid storage at a scale that actually moves the needle for the U.S. electricity system." The 183,000-square-foot plant, representing a $71 million investment, will produce up to 4 gigawatt-hours of storage annually when production begins in early 2027. That is enough output each year to serve nearly four million homes, and it signals that sodium-ion technology has moved from laboratory promise to commercial reality... Peak Energy, founded in 2023 by former engineers from Tesla, Enovix, and Fluence, announced its Sacramento site selection on July 8, 2026, after a nationwide search that ultimately chose California over Texas... The factory is designed as a system assembly plant rather than a cell fabrication facility. Peak will receive sodium-ion cells, manufactured to its specifications by Chinese suppliers, and assemble them into complete 30-foot-long, 100,000-pound containerized storage systems. Each GS1.1 unit stores 3.1 megawatt-hours, enough to fully charge more than 40 electric vehicles... In the United States, Peak Energy has emerged as the most advanced grid-scale player. It has secured more than 6 GWh of customer commitments, including a landmark deal with Jupiter Power for up to 4.75 GWh through 2030, valued at up to $500 million. Energy Vault has committed to 1.5 GWh of sodium-ion storage for AI data center applications, and RWE Americas has already deployed Peak's first grid-scale system on the MISO grid in Wisconsin, energized in March 2026. General Motors is codeveloping sodium-ion cells with Peak at its Wallace Battery Cell Innovation Center in Michigan, testing 170- and 190-amp-hour cell formats with domestic production targeted for 2028. China, however, remains the global heavyweight. CATL, the world's largest battery manufacturer, unveiled its TENER Sodium energy storage system in June 2026 with a rated cycle life of 15,000 cycles and a projected 25-to-30-year service life. In April 2026, CATL signed a 60 GWh supply agreement with HyperStrong, the largest sodium-ion deal announced to date. BYD, HiNa Battery, and Farasis are also shipping commercial sodium-ion products, including batteries for a $400 electric scooter already on sale in China... Peak Energy's first commercial shipments from Sacramento are slated for the first quarter of 2027, with contracted deliveries to Jupiter Power, Energy Vault, and RWE Americas following shortly after. The company has publicly stated it needs to deploy over $100 million in product in 2026, up from roughly $10 million in 2025, and the Sacramento facility is sized to meet that demand. At the system level, sodium-ion grid storage is already operating. Peak's pilot installation at the SolarTAC testing facility in Watkins, Colorado, stores 3.5 MWh and has been running since 2025. The RWE Americas deployment in Wisconsin, energized in March 2026, marks the first time sodium-ion batteries have backed up the MISO grid, which serves 15 central U.S. states and the Canadian province of Manitoba... According to the International Energy Agency, sodium-ion manufacturing capacity announcements have accelerated sharply since 2024, with global pipelines now exceeding 400 GWh annually... Researchers are also pushing the technology forward. In May 2026, a team at the National University of Singapore published a breakthrough in all-solid-state sodium batteries that could further reduce costs and eliminate the flammable liquid electrolytes found in both lithium-ion and current sodium-ion designs. "The technology's sweet spot is utility-scale, multi-megawatt-hour installations," the article points out, "where the system-level cost savings from passive cooling and longer cycle life outweigh the per-cell energy density penalty..." The article also points out observations from the American Battery Leadership Coalition, an industry group advocating for sodium-ion policy support, that sodium-ion batteries can be built almost entirely from American materials, including coal, sawdust, and agricultural waste. This week Syntropic Power and UNIGRID Inc. also announced "a major partnership to commercialize UNIGRID's proprietary sodium chromium oxide (NaCrO2) battery technology across North America," reports Interesting Engineering, "targeting one gigawatt-hour (1 GWh) of deployments in 2027. The technology could be used in residential, virtual power plant, and large-scale stationary grid applications..." Independent testing by the ISO-accredited Rochester Institute of Technology (RIT) Battery Development Center revealed something surprising. UNIGRID's 210Ah cells displayed endothermic behavior during charging. This means the chemical reaction actually absorbs heat rather than dumping it into the environment. Coupled with a 97.9% cell-level round-trip energy efficiency and remarkable thermal stability under abuse testing, the battery stays cool on its own. The 210Ah sodium-ion cells deliver up to 218Ah of discharge capacity. It demonstrated exceptional durability, retaining over 99% of its capacity after 1,000 full discharge cycles, as well as heat-absorbing behavior during charging. These validated strengths allow Syntropic to optimize its product designs, enabling platforms like GridSpan [its modular DC platform designed for large-scale energy applications with flexible discharge durations ranging from 20 minutes to 20 hours] to operate safely and efficiently at grid scale without needing complex mechanical cooling systems... Commercialization kicks off with Tenet, a safety-focused, wall-mounted system for residential, light-commercial, and virtual power plant uses... Relying on abundant and widely distributed raw materials like sodium and chromium — rather than lithium and cobalt — protects manufacturers from geopolitical price spikes and material shortages. Apart from offering an alternative to lithium, a successful rollout will demonstrate that the most durable energy storage is the kind that could stay cool entirely on its own.

An anonymous reader quotes a report from the BBC: German energy company RWE has said it will abandon its offshore wind projects in the U.S. after reaching a $1.2 billion payout deal with President Donald Trump's Department of the Interior (DoI). RWE said that it will now reinvest the sum into conventional gas projects, including $900 million in a liquefied natural gas (LNG) export terminal project in Louisiana. "After careful consideration, it was determined there is no path forward to permit these projects in the US for the foreseeable future," the company said in a statement. RWE said it has agreed to relinquish its leases off the California and Louisiana coasts as well as in the New York Bight. Overall, the German firm plans to invest approximately $19.6 billion in the U.S. over the next six years "to grow its generation capacity." Interior Secretary Doug Burgum said in a statement posted on X that Americans deserve an energy system built on common sense and not one dependent on "costly subsidies." "We welcome RWE's agreement and voluntary investment in projects that strengthen our nation's energy security," he added. Earlier this year, the DOL reached a deal with TotalEnergies putting an end to the French company's offshore wind projects in the U.S. "Instead, the firm agreed to reroute investment to build a LNG plant in Texas and to develop 'upstream conventional oil' in the Gulf of Mexico," reports the BBC. Another similar deal was signed with Charlotte-based Duke Energy last month to terminate the company's offshore wind lease in the Carolina Long Bay area.

An anonymous reader quotes a report from Ars Technica: Nowhere is the US data center boom bigger than in Texas. But less than a year after declaring Texas the "epicenter of AI development," Governor Greg Abbott has declared a moratorium on all new power grid connections for data centers -- at least until developers provide more information about their projects' potential impacts on the grid and communities. The Republican governor directed regulators in an August 3 announcement at the Public Utility Commission of Texas and the grid operators at the Electric Reliability Council of Texas (ERCOT) to perform a "comprehensive verification and audit of all data centers advancing through ERCOT's interconnection process." As an independent system operator, ERCOT oversees a power grid that operates separately from the rest of the United States and provides services to most of Texas. Texas has aggressively courted data center development with its availability of cheap land and relatively abundant energy resources, along with offering state incentives, like tax breaks and fewer regulations. That puts the state on track to surpass Virginia in becoming the largest US data center market. But the recent AI boom and the accompanying frenzy of data center development threaten to overwhelm the Texas grid on paper, despite the state leading the country in adding new power generation. The ERCOT interconnection queue currently includes more than 1,800 projects representing over 474 gigawatts' worth of requests to connect to the Texas grid -- more than five times Texas' record peak electricity demand -- and about 90 percent of those power connection requests come from data centers. "That unprecedented load growth could endanger the reliability and stability of the Texas electric grid," according to the statement from Abbott's office. Many of those data center projects may never materialize for various reasons. But ERCOT has still forecast that data center demand and other factors could drive statewide electricity demand to double the current demand record by 2032, according to The Texas Tribune. The review will examine each project's projected electricity consumption, reliance on the grid and state incentives, ownership, and water use. It will also assess measures intended to "reduce impacts on neighboring property owners and communities," including noise controls, lighting, traffic improvements, setbacks, and emergency planning. Ars Technica notes that the directive does not address air pollution or greenhouse-gas emissions and does not apply to data centers generating their own power on-site.

NextEra and Brookfield plan to invest more than $100 billion to transform a former uranium-enrichment site in Kentucky into a data center campus with a generating plant. "The privately funded effort will include construction of 2 gigawatts of natural gas-fired power at or near the site in Paducah in western Kentucky, and as much as 2.6 gigawatts of battery storage capacity," reports Bloomberg. " For context, a single gigawatt of capacity is roughly the output of a traditional nuclear power plant and can power about 750,000 homes at any given moment." From the report: Brookfield will develop and operate the 1.8 GW data center campus, which will occupy portions of the sprawling 3,556-acre Energy Department site once used to produce weapons-grade uranium and fuel for nuclear reactors. Operations using the now obsolete enrichment technology known as gaseous diffusion stopped in 2013 and the site is now subject to cleanup efforts. Construction is expected to be completed in 2031, the Energy Department said. "The U.S. government is leveraging its assets -- like our federal lands -- to add power generation, create jobs, and ensure the United States wins the AI race," Energy Secretary Chris Wright said in a statement. The project is expected to create 8,000 construction jobs and 600 permanent positions, the department said.

Politico reports that in the Virginia area alone there's dozens of data center projects "that altogether need 70 gigawatts of power — equivalent to 70 nuclear plants" — currently seeking connection to their grid. But there's also concerns about a Virginia data center powered with natural gas and backup diesel generators: When Virginia's top environmental regulator received an analysis warning of data center pollution, it took him less than five minutes to forward it to seven people on his staff... Internal emails obtained by POLITICO through a public records request paint a portrait of an agency that moved quickly to defend the only data center in Virginia that is powering itself — in what former officials and environmental health advocates described as an unusual effort to shape the debate around an industry whose global epicenter is in the state. The agency's pushback focused on the report's findings that the facility in Loudoun County could release harmful amounts of air pollution through eight bus-sized natural gas turbines — as allowed by permits granted by the Department of Environmental Quality [DEQ] itself... The request comes as data centers are devising new ways to produce their own power as a way to temper growing public discord over rising electricity prices amid the AI construction boom. Virginia has more than 600 data centers. The report [commissioned by Virginia's 54-year-old environmental nonprofit Piedmont Environmental Council] raised concerns that the data center's on-site power system, which also includes dozens of backup diesel generators, could cause tens of millions of dollars in health damages to people living around the facility, owned by Vantage Data Centers... [The analysis also argued the pollution could lead to 3.4 to 6.5 premature deaths annually.] People living near the Vantage facility in Sterling say its natural gas turbines produce constant noise and air pollution. The permits for Vantage issued by DEQ in 2023 allow cumulative emissions of seven different pollutants, including 95 tons per year of nitrogen oxides and more than 56 tons of soot. Both contribute to asthma and heart attacks. Those figures are in line with other state permits for minor sources of pollution, but DEQ's permits for Vantage have sparked local concerns because of the facility's location in a residential area... [Viriginia environmental quality officials] raised questions about whether the report wrongly described the facility's potential air pollution as dangerous, when soot levels in Loudoun County are deemed acceptable by America's Environmental Protection Agency (EPA). Health experts, including former EPA air quality official Michael Korber, told POLITICO that soot pollution can negatively affect human health even at EPA-approved levels. The World Health Organization's standard for ambient soot pollution is nearly half of what EPA suggests is safe. Some current and former staffers on Virginia's Department of Environmental Quality believe it's inappropriate for the agency to issue aggressive statements on the healthfulness of the data centers, with one former department leader saying Virginia's DEQ "is not the health department."

"The Norwegian certification agency DNV has certified the commercial wave-driven power generator Corpower C4 for regular use," writes Longtime Slashdot reader Qbertino. "German news site heise.de has a detailed write-up. See a CGI video of the power station and its internals, as well as the company's website [at their respective links]." From the report (translated to English): According to the manufacturer Corpower Ocean, it is the first DNV prototype certificate for a wave energy converter. The certificate confirms that Corpower's technology meets DNV's requirements for structural strength, reliability, and safety, Corpower Ocean announced. The certification process began in the design phase and lasted seven years. DNV oversaw the process from concept development through design, manufacturing, and assembly, to dry-running tests and subsequent operation. This is an important step, said Patrik Moller, CEO and one of the founders of Corpower Ocean. With the certification, wave energy is no longer just a promising technology, but a proven and financially viable one. This opens up new opportunities for project financing, insurance, and investments in commercial applications. The Corpower C4 wave power plant looks like a normal buoy: It consists of a 19-meter-long floating body with a diameter of 9 meters and a weight of approximately 11 tons. The system is anchored to the seabed. A mechanism inside the buoy converts its up-and-down movements in the waves into a rotary motion. This, in turn, drives a generator that produces electricity. The report notes that the company is "planning the first two industrial-scale wave energy farms off the coasts of Portugal and Scotland," which are scheduled to begin operating sometime between 2027 and 2029.

Anthropic is reportedly in very early talks to lease computing power from Meta in a potential deal worth around $10 billion. The discussions follow Anthropic's recent compute deal with SpaceX and come as Meta explores selling excess AI capacity as part of a broader push to turn its massive infrastructure spending into a cloud business. CNBC reports: Access to enough AI chips remains a challenge for firms like Anthropic, which places usage limits on its most advanced models like Fable. [...] Meta could spend as much as $145 billion on capital expenditures, including for AI infrastructure, in 2026. Last October, Zuckerberg said that companies are regularly "asking if we have compute that they could buy from us at some premium to what we've bought it at."

An anonymous reader quotes a report from Electrek: A Reddit post making the rounds this week claims the U.S. has experienced at least one major power outage every month of 2026 -- but is it true? I dug into several outages, the extreme weather behind them, and what we can do to help keep the lights on. [...] The claim that hundreds of thousands of Americans were without power over extended periods at least once per month, every month of 2026 surprised be in two ways. First, because I had no idea if it was true -- and, second, because it felt true. We try to do better than writing about things that feel true around here, however, so I did a bit of research (translation: I Googled power outages by month) and came up with the following examples in about sixty seconds January: More than 296,000 customers still without power as winter storm freezes much of the US February: More than 380,000 customers without power as winter storm hits US Northeast March: Storms Cut Power to Over 1 Million Customers in U.S. Midwest, Mid-Atlantic; Ohio Hardest Hit April: At least 29 tornadoes touched down in Central Illinois on April 17th May: Energy Secretary Issues Emergency Order to Deploy Backup Generation in the Mid-Atlantic Amid Heatwave June: More than 373,000 U.S. customers without power due to extreme weather ... and that list is far from comprehensive, and how you feel about it might depend on what you consider a "major" outage, of course -- but consider that there are tens of thousands of Americans without power right now, and that's not making the news. [...] The lesson here is that weather-related grid outages -- whether they're caused by wildfires, mudslides, derechos, tornadoes, ice storms, hurricanes, heat waves, or some other disaster I'm lucky enough to have forgotten about -- read like statistics when they're happening over there, but get personal real quick when they're happening to you.

An anonymous reader shared this report from TechCrunch: Two hundred and fifty years after the signing of the Declaration of Independence, a new commercial from Google asks: What if the Founding Fathers had access to Google Workspace? With the tagline "Group project, but make it 1776," the ad depicts a largely unseen Thomas Jefferson mid-draft when he gets a nagging text from Ben Franklin, leading to a very Google-centric collaboration process. Edits are suggested in Google Docs, a meeting gets scheduled in Google Calendar and conducted remotely via Google Meet (with every single attendee apparently turning their camera off?), then the whole thing is finalized with e-signatures; cue the fireworks. Of course, since this is an ad from a tech company in the year 2026, AI has a role to play. The fictionalized founders use Google's "help me visualize" AI tool to try out different animals on the national seal, Gemini takes notes on the meeting, and the founders also ask the chatbot for advice before declining King George III's document access request. TechCrunch call it "very tongue-in-cheek," noting that at one point Samuel Adams even asks, "Can we settle this over beers?" And they argue that "the AI evangelism is relatively discreet when compared to many other recent ads."

Startup Ampera has unveiled what it calls the first 3D-printed nuclear reactor module, built around a silicon-carbide core and pressure vessel designed for a thorium-based microreactor. The company says future systems could deliver 15 or 30 megawatts for up to 30 years without refueling. When The Register asked about availability, their spokesperson said: "We expect the power generation portion of the system to be available as early as 2027, with the nuclear module being available to customers about 2030 based on regulatory approval." From the report: Founder and CEO Brian Matthews revealed the prototype microreactor, which features a fully 3D-printed silicon carbide reactor core and pressure vessel. "This next-generation nuclear core and pressure vessel sets the foundation for factory-built, mass-produced nuclear energy," Matthews said. "The advanced technology and additive manufacturing used demonstrate a clear commercial path for new nuclear technology coming to market in an accelerated manner." His company is developing a subcritical, solid-state, factory-built thorium-based nuclear reactor. Subcritical means the fuel cannot sustain a nuclear chain reaction on its own, which prevents a runaway power excursion. Ampera uses "solid-state" to describe a design with solid rather than liquid fuel. The proposed fuel uses tristructural isotropic, or TRISO, particles, consisting of a fuel kernel containing thorium, surrounded by multiple ceramic and carbon layers. [...] "Thorium is the future for ultra-safe, clean power production," Matthews said at the time. "By producing TRISO thorium kernels in the United States, we can ensure ample access to the needed fuel supply as we scale up and also minimize price volatility risk." Ampera also describes the heart of the reactor as as a spherical monolithic gyroid core. A gyroid, as far as we can fathom, is a complex shape that provides a massive surface area relative to its volume, making it well-suited for heat transfer. Its complexity makes it difficult to produce using conventional manufacturing methods, which is where additive manufacturing comes in. The core is 3D-printed using silicon carbide and designed to operate for up to 30 years without refueling, the firm claims. Ampera says its planned systems will provide 15 or 30 MWe, depending on the configuration, enough to supply a typical datacenter. Larger configurations are planned. Matthews said that his company expects to be the first to industrialize factory-built nuclear power with near-term deployment timelines.

An anonymous reader quotes a report from Ars Technica: US homeowners have embraced home batteries in record-breaking numbers in early 2026, spurred on by state incentives while seeking to offset rising residential electricity costs. The trend could even unlock a more flexible energy supply for power grid operators and even AI data centers. New home battery installations reached a record 673 megawatts of energy storage in the first quarter of 2026, according to the US Energy Information Administration. That trend was driven by states with high electricity prices that have implemented policies to incentivize home battery installation, Bloomberg News reported. This residential battery trend stands out as a natural next step for states that have already successfully boosted rooftop solar adoption among homeowners, given how batteries enable homeowners to use stored solar energy at night. California and Hawaii accounted for the majority of new residential battery storage, while Texas and Arizona also saw significantly higher numbers of installations. California incentivizes homeowners with solar panels to also install batteries by offering better pricing for residential electricity exported to the grid after sunset, Bloomberg reported. Hawaii offers a one-time payment of $400 for every kilowatt of battery storage that homeowners install. However, the record-breaking home battery installations coincided with a slowdown in residential installations of solar panels -- the result of the Trump administration and Republican-driven One Big Beautiful Bill having eliminated a 30 percent federal solar tax credit for homeowners. Nonetheless, US electricity generation from solar power continues to rise and even surpassed coal-fired generation in April. The battery installation spree also coincides with rising electricity costs for US residential customers. The Energy Information Administration's latest data shows that the nationwide average for residential electricity costs increased by more than 7 percent in April 2026 when compared to electricity costs in April 2025. So homeowners with smart home battery-management systems could benefit from storing energy when electricity prices are lowest and draining them during peak demand periods.

An anonymous reader quotes a report from 404 Media: On June 26, the County Manager of Henrico County, Virginia, John Vithoulkas, sent an email to thousands of county employees asking them to help the local government conserve electricity. "Beginning July 1st, the rate we pay for electricity used in all Henrico County government and school facilities will increase dramatically -- by 25%, increasing costs by an estimated $5 million next fiscal year. We anticipate more rate increases for electricity in the years ahead," a copy of the email obtained by 404 Media said (emphasis his). Henrico County is a community of more than 350,000 people in eastern Virginia just outside of Richmond. It also hosts 37 data centers and there are plans to build 17 more, including plans to convert hundreds of acres of Civil War battlefields into data centers. Thanks to its proximity to DC and vast amounts of land, Henrico County became a data center hub seemingly overnight and its services clients big and small. Meta built a data center there in 2017. "To mitigate the impact of higher electric costs, I am asking that we, collectively, make slight adjustments to conserve electricity across our individual workspaces," Vithoulkas wrote in the email. "Turn off your lights when leaving your workspace, including when you leave for the day. Turn off your computers/laptops at the end of each workday. If your workspace has windows, adjust the blinds to manage heat from sunlight. Unplug any appliances, chargers, or other electrical items when they are not in use. Please limit use of (or refrain altogether from using) space heaters. A typical space heater alone can cost the county from $150 to $300 per year in electricity costs." "Each dollar we can save by conserving electricity is another dollar the county can reinvest into staff and the services we provide our residents," Vithoulkas email said.

America generated 10.06% more energy with renewables in the first four months of 2026 than it did in the same period the year before. That's according to new figures from America's Energy Information Administration, cited in this report from Electrek: The growth was led by utility-scale solar (+21.3%), hydropower (+15.7%), small-scale solar In April alone, wind and solar each produced more electricity than US coal plants, while the combination of solar and wind produced 57.0% more electricity than nuclear power. The mix of all renewables, including biomass and geothermal, accounted for 30.0% of total US electrical generation during the first third of 2026 — up from 27.8% a year earlier... EIA reported that, in April, utility-scale solar capacity surpassed wind capacity for the first time (160,208.1 MW vs. 160,100.6 MW). Further, utility-scale battery energy storage capacity increased by 17,703.5 MW, or 58.1%. Nuclear added just 18.4 MW. The combined capacity growth of all utility-scale renewable energy sources for the 12-month period (55,980.3 MW) is two-thirds more (i.e., 67.6%) than that added during the previous 12 months (33,392.0 MW). "EIA projects no new nuclear generating capacity and a net decline of 5,200.5 MW in fossil fuel capacity."

An anonymous reader quotes a report from Reuters: Spain will require mobile networks to have backup systems that maintain connectivity when power outages occur. Per a royal decree that will be approved by the end of 2026, mobile network operators (MNOs) and infrastructure companies will need to install batteries or other backups to keep service active for at least four hours during a blackout. The mobile network rules will apply to businesses that serve at least 500,000 users or generate upwards of 50 million euros ($56.9 million) in annual revenue. The decree will stipulate that half of the population will need to be covered by this failsafe within the first year, then 65 percent in the second year and three quarters in the third. [...] The decree will require other key infrastructure elements to remain up and running for a certain period after a power outage. For instance, control centers that could impact all of Spain if they were to go offline will need to remain in service for at least 24 hours. Emergency call centers will also need to have plans in place to maintain operations, as Reuters notes. The move is in response to the widespread blackout across the Iberian peninsula in 2025, which left more than 50 million people without power. Experts called it "the most severe and unprecedented blackout that had occurred in Europe in the past 20 years."

An anonymous reader quotes a report from Barron's: Walmart is signing a long-term contract to buy nuclear power for the first time ever, a promising sign that the industry's future is supported by more than just the AI data center boom. The retail giant agreed on Tuesday to buy power from a nuclear plant in Illinois owned by Constellation Energy for its operations in the area, including its stores and a high-tech warehouse in Illinois that stores and sorts perishable food. Walmart will buy 176 megawatts of power from the plant over a 15-year period, or enough power to serve around 150,000 homes. The Walmart deal will allow Constellation to expand the capacity of the Illinois plant by 30 megawatts, a process known as an uprate, which can involve replacing older equipment and improving efficiency. Walmart, which has pledged to eliminate net carbon emissions from its U.S. operations by 2040, will also receive the environmental attributes associated with the nuclear energy, which generates electricity without carbon emissions.

An anonymous reader quotes a report from the Associated Press: The Trump administration is providing $17.5 billion to speed the development of 10 new large nuclear reactors to meet the skyrocketing power demand from massive data centers. Energy Secretary Chris Wright cited "tremendous interest" among developers of data centers that would buy the power, as well as utilities and energy companies. The nuclear plants could begin construction by 2030 and become operational in the mid-2030s, Wright and other officials said Tuesday. "This is the start," Wright said on a call with reporters. "We're going to move with the players that are ready to stand up and move quickly. Once that supply chain is up and running, do we think there will be dozens of these built going forward? I'd be very surprised if there were not." Most U.S. nuclear power plants were built between 1970 and 1990. Only two new large reactors have been built from scratch in the United States in recent decades. Those two reactors, at Georgia Power Co.'s Plant Vogtle, were completed years late and billions of dollars over budget. The 10 new reactors will use the same design, Westinghouse's AP1000. Wright said the Plant Vogtle project struggled because of bad planning, supply chain problems and the COVID-19 pandemic. But, he said, the reactor design is "robust and sound."

Canada has unveiled a national strategy to build up to 10 new nuclear reactors over the next 15 years as it seeks to double electricity-grid capacity by 2050. Energy Minister Tim Hodgson called it a plan for a "new civilian nuclear renaissance." "If our goal is to double our grid and build a low-carbon economy in less than 25 years, there is no credible plan to do that without nuclear energy and the clean, reliable baseload power it provides," Hodgson said. "There is no credible plan for Canada to become an energy superpower if we choose not to build upon one of the strongest energy advantages we have." CBC News reports: The strategy calls for construction to start on two new large-scale reactors by 2035, for five more to be planned or under development by 2040 and for at least one reactor to be under construction outside Ontario by 2035. It also calls for a Canadian-made microreactor to be finalized by 2035 and deployed to a remote community by the late 2030s. [...] Right now, Canada has four nuclear power plants -- three in Ontario and one in New Brunswick -- which generate about 15 per cent of Canada's electricity. A new proposed facility at the existing nuclear plant in Darlington, Ont., would see the first small modular reactor in the G7, capable of producing up to 300 megawatts per unit. Saskatchewan is also looking at the potential to bring small nuclear reactors online by the mid 2030s. The energy deal between Ottawa and Alberta also committed to collaborating on developing a strategy to build a nuclear power plant. Officials from Natural Resources Canada told reporters in a background briefing that construction of the reactors outlined in the new national strategy could cost more than $100 billion. The strategy does not say how Canada would pay for them, though an official pointed to the Canadian Infrastructure Bank and the Canada Growth Fund as possible funding sources. Hodgson said the strategy would double the 90,000 jobs in Canada's nuclear sector "over the coming decades." The plan also looks to expand sales of Candu reactors to new export markets. It says the government wants to break into at least four new international markets by 2040 and "engage six to 10 new nuclear entrant markets over a 15-year horizon, cementing Canada as their partner of choice." Thirty Candu reactors currently operate around the world, including in South Korea, China, India, Argentina, Pakistan and Romania, and there are plans to build two more. [...] "Reactor exports are not transactional. They establish multi-decade partnerships, creating durable geopolitical and commercial relationships that advance Canada's broader foreign policy interests," the strategy says. "As Canada works to diversify its trading relationships and strengthen ties with middle powers, Candu can be a central instrument of that strategy."

"There's a revolution in battery technology hiding in plain sight," reports The Wall Street Journal. "The 3-D printing of batteries has the potential to put energy storage inside any device. "This will enable lightweight and long-lasting consumer gadgets, long-range military drones and even nanoscale robots." Almost all the innovations we regularly hear about — from cheaper, tougher electric-vehicle batteries to "Holy Grail" solid-state batteries — are about changing the chemistry of batteries. The promise of battery-tech 3-D printing (aka additive manufacturing) is simple: What if batteries could fill any available space, even structural elements of our gadgets, rather than always taking a rigid shape like a pouch or cylinder? The new approach has obvious appeal. The entire airframe of a drone could be filled with energy storage for increased range. Smartglasses could have sleek battery-packed frames, so they look like everyday eyewear rather than "Revenge of the Nerds" props. One of the biggest advantages of 3-D printing is that it works with any battery, regardless of its cell chemistry. It could advance today's lithium-ion as well as emerging sodium-ion and solid-state tech... Some [startups] are trying to use 3-D printing to create efficiencies in existing battery manufacturing systems. A brave handful of startups are pursuing radical new designs and approaches. They're starting with defense applications, where cost and scale are less of an issue... At Silicon Valley-based Sakuu... [r]ather than trying to 3-D-print whole batteries, the company is working on replacing one of battery manufacturing's biggest pain points, says Arwed Niestroj, Sakuu's chief operating officer, who is also a nuclear physicist and former head of Mercedes-Benz Research & Development North America. Existing battery assembly lines include football-field-long ovens for drying layers of material that have been dissolved in solvents. This requires a huge amount of energy and is a significant contributor to manufacturing costs, a big reason EV batteries aren't cheaper. Sakuu's process, under development for years, uses additive manufacturing to lay down key battery components without solvents, eliminating the need for ovens, says Niestroj. Sakuu is currently working to commercialize this tech with a major battery manufacturer...

"Asian stocks rallied Monday while oil prices tumbled," reports CNBC, "after the U.S. and Iran agreed to a peace deal aimed at ending nearly four months of conflict..." The strongest reaction was seen in energy markets. U.S. crude oil futures for July delivery were down 4.77% to $80.83 per barrel by 8:27 p.m. ET. Brent futures, the international benchmark, for August delivery traded about 4% lower to $83.77 per barrel. Asian equities surged. South Korea's Kospi jumped 5.1%, Japan's Nikkei 225 climbed 3.6%, and the broader Topix advanced 2.6%... The U.S. dollar index weakened 0.32% to 99.483, while the yield on the benchmark 10-year Treasury note fell 5 basis points to 4.423%, suggesting that investors were dialing back inflation concerns on easing energy prices. "The most immediate implication is a repricing of the inflation risk premium that markets have been carrying since the Strait closed," said Billy Leung, investment strategist at Global X ETFs... Besides safe-haven Treasurys, gold also rose. "Gold is the interesting outlier here," Leung said. "In a clean risk-on trade, gold should be selling off as the geopolitical premium unwinds, but it is holding bid around $4,300, which tells you the market is not fully trusting the deal yet." Spot gold prices were up almost 2% at $4,302.19 per ounce. That skepticism reflects lingering uncertainty around the agreement, which remains unsigned and subject to implementation risks. [Josh Gilbert, lead Asia Pacific analyst at trading platform eToro] cautioned that "the deal isn't actually signed until June 19th, the details are still thin, and this conflict has shown more than once that headlines can turn on a dime." Analysts at Commonwealth Bank of Australia also stressed that the oil outlook hinges on how quickly shipping and production can normalize. Vivek Dhar, head of commodities and sustainability research at CBA, expects Brent to fall to around $80 a barrel by year-end, assuming the Strait remains open and exports recover. However, he warned that damage to refining infrastructure, the presence of sea mines and uncertainty over tanker traffic could slow the return to normal operations. Even so, he said markets are likely to take comfort from the prospect that oil flows need only recover to around 60%-70% of pre-war levels to restore expectations of a global supply surplus. For investors, the biggest implication will likely be what cheaper energy means for inflation and central banks. Lower oil prices ease pressure on households and businesses while reducing the risk of a broader inflation resurgence just as major central banks enter a busy week of policy meetings. UPDATE: "A US official is rejecting Iran's assertion that it will receive billions of dollars in frozen funds before a planned 60-day negotiating period begins following Friday's signing of an agreement," reports CNN: The pushback came after Iran's deputy foreign minister, Kazem Gharibabadi, said the next phase of talks would depend on Washington first fulfilling several obligations, including releasing Iranian funds frozen abroad. The differing accounts underscore a significant gap between how the United States and Iran are describing what must happen before the next round of negotiations can move forward.
