Dow, a major producer of chemicals and plastics, wants to use next-generation nuclear reactors for clean power and steam at a Texas manufacturing complex instead of natural gas.

Dow's subsidiary, Long Mott Energy, applied Monday to the U.S. Nuclear Regulatory Commission for a construction permit. It said the project with X-energy, an advanced nuclear reactor and fuel company, would nearly eliminate the emissions associated with power and steam generation at its plant in Seadrift, Texas, avoiding roughly 500,000 metric tons of planet-warming greenhouse gas emissions annually.

If built and operated as planned, it would be the first U.S. commercial advanced nuclear power plant for an industrial site, according to the NRC.

For many, nuclear power is emerging as an answer to meet a soaring demand for electricity nationwide, driven by the expansion of data centers and artificial intelligence, manufacturing and electrification, and to stave off the worst effects of a warming planet. However, there are safety and security concerns, the Union of Concerned Scientists cautions. The question of how to store hazardous nuclear waste in the U.S. is unresolved, too.

Dow wants four of X-energy's advanced small modular reactors, the Xe-100. Combined, those could supply up to 320 megawatts of electricity or 800 megawatts of thermal power. X-energy CEO J. Clay Sell said the project would demonstrate how new nuclear technology can meet the massive growth in electricity demand.

The Seadrift manufacturing complex, at about 4,700 acres, has eight production plants owned by Dow and one owned by Braskem. There, Dow makes plastics for a variety of uses including food and beverage packaging and wire and cable insulation, as well as glycols for antifreeze, polyester fabrics and bottles, and oxide derivatives for health and beauty products.

Edward Stones, the business vice president of energy and climate at Dow, said submitting the permit application is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the United States. The project is supported by the Department of Energy’s Advanced Reactor Demonstration Program.

The NRC expects the review to take three years or less. If a permit is issued, construction could begin at the end of this decade, so the reactors would be ready early in the 2030s, as the natural gas-fired equipment is retired.

A total of four applicants have asked the NRC for construction permits for advanced nuclear reactors. The NRC issued a permit to Abilene Christian University for a research reactor and to Kairos Power for one reactor and two reactor test versions of that company's design. It's reviewing an application by Bill Gates and his energy company, TerraPower, to build an advanced reactor in Wyoming.

X-energy is also collaborating with Amazon to bring more than 5 gigawatts of new nuclear power projects online across the United States by 2039, beginning in Washington state. Amazon and other tech giants have committed to using renewable energy to meet the surging demand from data centers and artificial intelligence and address climate change.

Supreme Court confronts what to do with growing pile of nuclear waste

The Debate Continues

The Supreme Court will hear arguments Wednesday in a fight over plans to store nuclear waste at sites in rural Texas and New Mexico.President Joe Biden's administration and a private company with a license for the Texas facility appealed a ruling by the 5th U.S. Circuit Court of Appeals that found that the Nuclear Regulatory Commission exceeded its authority in granting the license. The outcome of the case will affect plans for a similar facility in New Mexico roughly 40 miles away.

On this issue, President Donald Trump's administration is sticking with the views of its predecessor, even with Texas Gov. Greg Abbott, a Republican ally of Trump, on the other side.

The push for temporary storage sites is part of the complicated politics of the nation’s so far futile quest for a permanent underground storage facility.

Here's what to know about the case.

Where is spent nuclear fuel stored now?

Roughly 100,000 tons of spent fuel, some of it dating from the 1980s, is piling up at current and former nuclear plant sites nationwide and growing by more than 2,000 tons a year. The waste was meant to be kept there temporarily before being deposited deep underground.

A plan to build a national storage facility northwest of Las Vegas at Yucca Mountain has been mothballed because of staunch opposition from most Nevada residents and officials.

The Nuclear Regulatory Commission has said that the temporary storage sites are needed because existing nuclear plants are running out of room. The presence of the spent fuel also complicates plans to decommission some plants, the Justice Department said in court papers.

Where would it go?

The NRC granted the Texas license to Interim Storage Partners LLC for a facility that could take up to 5,000 metric tons of spent nuclear fuel rods from power plants and 231 million tons of other radioactive waste. The facility would be built next to an existing dump site in Andrews County for low-level waste, such as protective clothing and other material that has been exposed to radioactivity. The Andrews County site is about 350 miles west of Dallas, near the Texas-New Mexico state line.

The New Mexico facility would be in Lea County, in the southeastern part of the state near Carlsbad. The NRC gave a license for the site to Holtec International.

The licenses would allow for 40 years of storage, although opponents contend the facilities would be open indefinitely because of the impasse over permanent storage.

Political opposition is bipartisan

Republicans and Democrats, environmental groups and the oil and gas industry all oppose the temporary sites.

Abbott is leading Texas' opposition to the storage facility. New Mexico Democratic Gov. Michelle Lujan Grisham also is opposed to the facility planned for her state.

A brief led by Republican Texas Sen. Ted Cruz on behalf of several lawmakers calls the nuclear waste contemplated for the two facilities an “enticing target for terrorists” and argues it's too risky to build the facility atop the Permian Basin, the giant oil and natural gas region that straddles Texas and New Mexico.

Elected leaders of communities on the routes the spent fuel likely would take to New Mexico and Texas also are opposed.

What are the issues before the court?

The justices will consider whether, as the NRC argues, the states forfeited their right to object to the licensing decisions because they declined to join in the commission’s proceedings.

Two other federal appeals courts, in Denver and Washington, that weighed the same issue ruled for the agency. Only the 5th Circuit allowed the cases to proceed.

The second issue is whether federal law allows the commission to license temporary storage sites. Opponents are relying on a 2022 Supreme Court decision that held that Congress must act with specificity when it wants to give an agency the authority to regulate on an issue of major national significance. In ruling for Texas, the 5th Circuit agreed that what to do with the nation’s nuclear waste is the sort of “major question” that Congress must speak to directly.

But the Justice Department has argued that the commission has long-standing authority to deal with nuclear waste reaching back to the 1954 Atomic Energy Act.

Texas, New Mexico officials contemplate what to do with nuclear waste

in debate

Federal officials gathered Tuesday in southern New Mexico to mark the 25th anniversary of the nation’s only underground repository for radioactive waste resulting from decades of nuclear research and bomb making.

Carved out of an ancient salt formation about half a mile (800 meters) deep, the Waste Isolation Pilot Plant outside Carlsbad has taken in around 13,850 shipments from more than a dozen national laboratories and other sites since 1999.

The anniversary comes as New Mexico raises concerns about the federal government’s plans for repackaging and shipping to WIPP a collection of drums filled with the same kind of materials that prompted a radiation release at the repository in 2014.

That mishap contaminated parts of the underground facility and forced an expensive, nearly three-year closure. It also delayed the federal government’s multibillion-dollar cleanup program and prompted policy changes at labs and other sites across the U.S.

Meanwhile, dozens of boxes containing drums of nuclear waste that were packed at the Los Alamos National Laboratory to be stored at WIPP were rerouted to Texas, where they've remained ever since at an above-ground holding site.

After years of pressure from Texas environmental regulators, the U.S. Department of Energy announced last year that it would begin looking at ways to treat the waste so it could be safely transported and disposed of at WIPP.

But the New Mexico Environment Department is demanding more safety information, raising numerous concerns in letters to federal officials and the contractor that operates the New Mexico repository.

“Parking it in the desert of West Texas for 10 years and shipping it back does not constitute treatment,” New Mexico Environment Secretary James Kenney told The Associated Press in an interview. “So that’s my most substantive issue — that time does not treat hazardous waste. Treatment treats hazardous waste.”

The 2014 radiation release was caused by improper packaging of waste at Los Alamos. Investigators determined that a runaway chemical reaction inside one drum resulted from the mixing of nitrate salts with organic kitty litter that was meant to keep the interior of the drum dry.

Kenney said there was an understanding following the breach that drums containing the same materials had the potential to react. He questioned how that risk could have changed since the character and composition of the waste remains the same.

Scientists at Sandia National Laboratories in Albuquerque were contracted by the DOE to study the issue. They published a report in November stating that the federal government's plan to repackage the waste with an insulating layer of air-filled glass micro-bubbles would offer “additional thermal protection."

The study also noted that ongoing monitoring suggests that the temperature of the drums is decreasing, indicating that the waste is becoming more stable.

DOE officials did not immediately answer questions about whether other methods were considered for changing the composition of the waste, or what guarantees the agency might offer for ensuring another thermal reaction doesn't happen inside one of the drums.

The timetable for moving the waste also wasn't immediately clear, as the plan would need approval from state and federal regulators.

Kenney said some of the state's concerns could have been addressed had the federal government consulted with New Mexico regulators before announcing its plans. The state in its letters pointed to requirements under the repository's permit and federal laws for handling radioactive and hazardous wastes.

Don Hancock, with the Albuquerque-based watchdog group Southwest Research and Information Center, said shipments of the untreated waste also might not comply with the Nuclear Regulatory Commission's certification for the containers that are used.

“This is a classic case of waste arriving somewhere and then being stranded — 10 years in the case of this waste,” Hancock said. “That’s a lesson for Texas, New Mexico, and any other state to be sure that waste is safe to ship before it’s allowed to be shipped.”

Houston researchers make headway on developing low-cost sodium-ion batteries

energy storage

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

ExxonMobil lands major partnership for clean hydrogen facility in Baytown

power deal

Exxon Mobil and Japanese import/export company Marubeni Corp. have signed a long-term offtake agreement for 250,000 tonnes of low-carbon ammonia per year from ExxonMobil’s forthcoming facility in Baytown, Texas.

“This is another positive step forward for our landmark project,” Barry Engle, president of ExxonMobil Low Carbon Solutions, said in a news release. “By using American-produced natural gas we can boost global energy supply, support Japan’s decarbonization goals and create jobs at home. Our strong relationship with Marubeni sets the stage for delivering low-carbon ammonia from the U.S. to Japan for years to come."

The companies plan to produce low-carbon hydrogen with approximately 98% of CO2 removed and low-carbon ammonia. Marubeni will supply the ammonia mainly to Kobe Power Plant, a subsidiary of Kobe Steel, and has also agreed to acquire an equity stake in ExxonMobil’s low-carbon hydrogen and ammonia facility, which is expected to be one of the largest of its kind.

The Baytown facility aims to produce up to 1 billion cubic feet daily of “virtually carbon-free” hydrogen. It can also produce more than 1 million tons of low-carbon ammonia per year. A final investment decision is expected in 2025 that will be contingent on government policy and necessary regulatory permits, according to the release.

The Kobe Power Plant aims to co-fire low-carbon ammonia with existing fuel, and reduce CO2 emissions by Japan’s fiscal year of 2030. Marubeni also aims to assist the decarbonization of Japan’s power sector and steel manufacturing industry, chemical industry, transportation industry and various others sectors.

“Marubeni will take this first step together with ExxonMobil in the aim of establishing a global low-carbon ammonia supply chain for Japan through the supply of low-carbon ammonia to the Kobe Power Plant,” Yoshiaki Yokota, senior managing executive officer at Marubeni Corp., added in the news release. “Additionally, we aim to collaborate beyond this supply chain and strive towards the launch of a global market for low-carbon ammonia. We hope to continue to actively cooperate with ExxonMobil, with a view of utilizing this experience and relationship we have built to strategically decarbonize our power projects in Japan and Southeast Asia in the near future.”

Houston expert: The role of U.S. LNG in global energy markets

guest column

The debate over U.S. Liquefied Natural Gas (LNG) exports is too often framed in misleading, oversimplified terms. The reality is clear: LNG is not just a temporary fix or a bridge fuel, it is a fundamental pillar of global energy security and economic stability. U.S. LNG is already reducing coal use in Asia, strengthening Europe’s energy balance, and driving economic growth at home. Turning away from LNG exports now would be a shortsighted mistake, undermining both U.S. economic interests and global energy security.

Ken Medlock, Senior Director of the Baker Institute’s Center for Energy Studies, provides a fact-based assessment of the U.S. LNG exports that cuts through the noise. His analysis, consistent with McKinsey work, confirms that U.S. LNG is essential to balancing global energy markets for the decades ahead. While infrastructure challenges and environmental concerns exist, the benefits far outweigh the drawbacks. If the U.S. fails to embrace its leadership in LNG, we risk giving up our position to competitors, weakening our energy resilience, and damaging national security.

LNG Export Licenses: Options, Not Guarantees

A common but deeply flawed argument against expanding LNG exports is the assumption that granting licenses guarantees unlimited exports. This is simply incorrect. As Medlock puts it, “Licenses are options, not guarantees. Projects do not move forward if they are unable to find commercial footing.”

This is critical: government approvals do not dictate market outcomes. LNG projects must navigate economic viability, infrastructure feasibility, and global demand before becoming operational. This reality should dispel fears that expanded licensing will automatically lead to an uncontrolled surge in exports or domestic price spikes. The market, not government restrictions, should determine which projects succeed.

Canada’s Role in U.S. Gas Markets

The U.S. LNG debate often overlooks an important factor: pipeline imports from Canada. The U.S. and Canadian markets are deeply intertwined, yet critics often ignore this reality. Medlock highlights that “the importance to domestic supply-demand balance of our neighbors to the north and south cannot be overstated.”

Infrastructure Constraints and Price Volatility

One of the most counterproductive policies the U.S. could adopt is restricting LNG infrastructure development. Ironically, such restrictions would not only hinder exports but also drive up domestic energy prices. Medlock’s report explains this paradox: “Constraints that either raise development costs or limit the ability to develop infrastructure tend to make domestic supply less elastic. Ironically, this has the impact of limiting exports and raising domestic prices.”

The takeaway is straightforward: blocking infrastructure development is a self-inflicted wound. It stifles market efficiency, raises costs for American consumers, and weakens U.S. competitiveness in global energy markets. McKinsey research confirms that well-planned infrastructure investments lead to greater price stability and a more resilient energy sector. The U.S. should be accelerating, not hindering, these investments.

Short-Run vs. Long-Run Impacts on Domestic Prices

Critics of LNG exports often confuse short-term price fluctuations with long-term market trends. This is a mistake. Medlock underscores that “analysis that claims overly negative domestic price impacts due to exports tend to miss the distinction between short-run and long-run elasticity.”

Short-term price shifts are inevitable, driven by seasonal demand and supply disruptions. But long-term trends tell a different story: as infrastructure improves and production expands, markets adjust, and price impacts moderate. McKinsey analysis suggests supply elasticity increases as producers respond to price signals. Policy decisions should be grounded in this broader economic reality, not reactionary fears about temporary price movements.

Assessing the Emissions Debate

The argument that restricting U.S. LNG exports will lower global emissions is fundamentally flawed. In fact, the opposite is true. Medlock warns against “engineering scenarios that violate basic economic principles to induce particular impacts.” He emphasizes that evaluating emissions must be done holistically. “Constraining U.S. LNG exports will likely mean Asian countries will continue to turn to coal for power system balance,” a move that would significantly increase global emissions.

McKinsey’s research reinforces that, on a lifecycle basis, U.S. LNG produces fewer emissions than coal. That said, there is room for improvement, and efforts should focus on minimizing methane leakage and optimizing gas production efficiency.

However, the broader point remains: restricting LNG on environmental grounds ignores the global energy trade-offs at play. A rational approach would address emissions concerns while still recognizing the role of LNG in the global energy system.

The DOE’s Commonwealth LNG Authorization

The Department of Energy’s recent conditional approval of the Commonwealth LNG project is a step in the right direction. It signals that economic growth, energy security, and market demand remain key considerations in regulatory decisions. Medlock’s analysis makes it clear that LNG exports will be driven by market forces, and McKinsey’s projections show that global demand for flexible, reliable LNG is only increasing.

The U.S. should not limit itself with restrictive policies when the rest of the world is demanding more LNG. This is an opportunity to strengthen our position as a global energy leader, create jobs, and ensure long-term energy security.

Conclusion

The U.S. LNG debate must move beyond fear-driven narratives and focus on reality. The facts are clear: LNG exports strengthen energy security, drive economic growth, and reduce global emissions by displacing coal.

Instead of restrictive policies that limit LNG’s potential, the U.S. should focus on expanding infrastructure, maintaining market flexibility, and supporting innovation to further reduce emissions. The energy transition will be shaped by market realities, not unrealistic expectations.

The U.S. has an opportunity to lead. But leadership requires embracing economic logic, investing in infrastructure, and ensuring our policies are guided by facts, not political expediency. LNG is a critical part of the global energy landscape, and it’s time to recognize its long-term strategic value.
