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.”

Oxy CEO Vicki Hollub to retire, Reuters reports

retirement plans

Vicki Hollub, CEO of Houston-based Occidental (Oxy), is set to retire this year, Reuters first reported Thursday.

Hollub has held the top leadership position at Oxy since 2016 and has been with the oil and gas giant for more than 40 years. Before being named CEO, she served as chief operating officer and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Reuters reports that a firm date for her retirement has not been set. Richard Jackson, who currently serves as Oxy's COO, is expected to replace Hollub in the CEO role.

Oxy is leading a number of energy transition projects.

It's subsidiary 1PointFive is developing a $1.3 billion direct air capture (DAC) project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year.

The company shared recently that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos last year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” she added.

Oxy was one of the first to set ambitious net-zero goals. In a 2020 interview during CERAWeek, Hollub outlined Oxy's future as a “carbon management company.”

“Ultimately, I don’t know how many years from now, Occidental becomes a carbon management company, and our oil and gas would be a support business unit for the management of that carbon. We would be not only using [CO2] in oil reservoirs [but] capturing it for sequestration as well,” Hollub said.

Oxy opened its Oxy Innovation Center in the Ion last year, focused on advancing low-carbon technology. It also operates Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others.

Hertha Metals named world's  No. 1 most innovative manufacturing co. of 2026

top innovators

Led by Conroe-based Hertha Metals, five organizations in the Houston area earned shoutouts on Fast Company’s list of the World’s Most Innovative Companies of 2026.

Hertha Metals ranked No. 1 in the manufacturing category.

Last year, Hertha unveiled a single-step process for steelmaking that it says is cheaper, more energy-efficient and just as scalable as traditional steel manufacturing. It started testing the process in 2024 at a one-metric-ton-per-day pilot plant.

At the same time, Hertha announced more than $17 million in venture capital funding from investors such as Breakthrough Energy, Clean Energy Ventures, Khosla Ventures, and Pear VC.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Laureen Meroueh, founder and CEO of Hertha, said at the time.

Meroueh was also recently named to Inc. Magazine's 2026 Female Founders 500 list.

Hertha, founded in 2022, says traditional steelmaking relies on an outdated, coal-based multistep process that is costly, and contributes up to 9 percent of industrial energy use and 10 percent of global carbon emissions.

By contrast, Hertha’s method converts low-grade iron ore into molten steel or high-purity iron in one step. The company says its process is 30 percent more energy-efficient than traditional steelmaking and costs less than producing steel in China.

Last year, Hertha said it planned to break ground in 2026 on a plant capable of producing more than 9,000 metric tons of steel per year. In its next phase, the company plans to operate at 500,000 metric tons of steel production per year.

Here are Fast Company’s rankings for the four other Houston-area organizations:

  • Houston-based Vaulted Deep, No. 3 in catchall “other” category.
  • XGS Energy, No. 7 in the energy category. XGS’ proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock is located. While Fast Company lists Houston as XGS’ headquarters, and the company has a major presence in the city, XGS is based in Palo Alto, California.
  • Houston-based residential real estate brokerage Epique Realty, No. 10 in the business services category. Epique, which bills itself as the industry’s first AI brokerage, provides a free AI toolkit for real estate agents to enhance marketing, streamline content creation, and improve engagement with clients and prospects.
  • Texas A&M University’s Nanostructured Materials Lab in College Station. The lab studies nano-structured materials to make materials lighter for the aerospace industry, improve energy storage, and enable the creation of “smart” textiles.
