Baltimore-based nuclear power company Constellation Energy Corp. received final regulatory clearance this month to acquire Houston-based Calpine Corp. for a net purchase price of $26.6 billion.

The acquisition has the potential to create America’s “largest clean energy provider,” the companies reported when the deal was first announced in January.

The Department of Justice approved the acquisition contingent on Calpine divesting several assets, including one in the Houston area.

The company agreed to divest the Jack Fusco Energy Center natural gas-fired combined cycle facility in Richmond, Texas; four generating assets in the Mid-Atlantic region; and other natural gas plants in Pennsylvania and Corpus Christi, Texas.

The Federal Energy Regulatory Commission, the Public Utility Commission of Texas and the New York Public Service Commission previously approved the deal. The companies can move toward closing the acquisition once the court finalizes the stipulation and order.

"We are very pleased to reach a settlement that allows us to bring together two magnificent companies to create a new Constellation with unprecedented scale, talent and capability to better serve our customers and communities while building the foundation for America’s next great era of growth and innovation," Joe Dominguez, president and CEO of Constellation, said in a news release. "We thank the Department for its professionalism and tireless work reviewing this transaction through these many months. It’s now time for us to complete the transaction, welcome our new colleagues from Calpine, and together begin our journey to light the way to a brilliant tomorrow for all."

Andrew Novotny, CEO of Calpine, will continue to lead the Calpine business and Constellation's fleet of natural gas, hydro, solar and wind generation, according to the company. He will report to Dominguez and also serve as senior executive vice president of Constellation Power Operations.

Constellation is considered one of the top clean energy producers in the U.S. Earlier this month, the company was approved to receive a $1 billion loan from the Department of Energy's Energy Dominance Financing Program to restart its 835-megawatt nuclear reactor in Pennsylvania known as Crane Clean Energy Center.

"Work to restart the reactor comes at a time of unprecedented electric demand growth from electrification and the new data centers needed to support a growing digital economy and to help America win the AI race," a news release from the company reads. "Crane will support grid stability by delivering reliable, around-the-clock electric supply."

Houston-area clean energy projects lose more than $700M in federal funds

funding cut

The federal government has canceled more than $700 million in funding for three clean energy projects in the Houston area.

In all, the U.S. Department of Energy (DOE) recently wiped out $3.7 billion in funding for 24 carbon capture and decarbonization projects across the country.

Houston-area projects that took a hit are:

It’s unclear how the loss of federal funding will affect the three Houston-area projects.

All $3.7 billion from the DOE was awarded in 2024 and 2025 during the Biden administration—in some cases days before President Trump took office.

“While the previous administration failed to conduct a thorough financial review before signing away billions of taxpayer dollars, the Trump administration is doing our due diligence to ensure we are utilizing taxpayer dollars to strengthen our national security, bolster affordable, reliable energy sources, and advance projects that generate the highest possible return on investment,” U.S. Energy Secretary Chris Wright said in a release.

Advocates for clean energy sharply criticized the DOE’s action:

  • Jessie Stolark, executive director of the Carbon Capture Coalition, said cancellation of the 24 DOE-funded projects “is a major step backward in the nationwide deployment of carbon management technologies. It is hugely disappointing to see these projects canceled — projects that had already progressed through a rigorous, months-long review process by technical experts at DOE.”
  • Iliana Paul, deputy director for the Sierra Club’s industrial transformation campaign, complained that the Trump administration “killed dozens of major investments in American competitiveness, good jobs, and cleaner air to support Trump’s tax cuts and line the pockets of billionaires. These projects were not just pro-climate; they were pro-jobs, pro-innovation, and pro-public health. American workers, fenceline communities, and forward-thinking companies have had the rug pulled out from under them.”
  • Conrad Schneider, senior U.S. director of the Clean Air Taskforce, said the DOE’s move “is bad for U.S. competitiveness in the global market and also directly contradictory to the administration’s stated goals of supporting energy production and environmental innovation. Canceling cutting-edge technology demonstrations, including support for carbon capture and storage projects, undercuts U.S. competitiveness at a time when there is a growing global market for cleaner industrial products and technologies.”

Exxon expands CO2 storage network with Calpine agreement

power deal

ExxonMobil Corp. has agreed to transport and permanently store up to 2 million metric tons per year of CO2 from Calpine Corp.’s Baytown Energy Center.

The strategic agreement is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project, which is designed to capture the energy center’s CO2 emissions and enable the supply of low-carbon electricity. It’s also in line with Exxon’s broader strategy to expand its CCS infrastructure along the Gulf Coast.

“Calpine is excited to partner with ExxonMobil to achieve this important project milestone,” Caleb Stephenson, Calpine Executive Vice President, said in a news release. “As the largest U.S. generator of electricity from natural gas, we understand that the nation’s gas fleet will remain the backbone of the grid for decades to come. We believe CCS is an actionable and cost-effective way to meet customers' demand for reliable power and alleviate concerns about the indisputable long-term need for gas-fired facilities. Low-cost natural gas along with carbon capture technology and widespread geologic storage resources can bolster U.S. energy, natural gas use, jobs, and export strength.”

The Baytown CCS Project is expected to produce about 500 megawatts of low-carbon electricity, which Calpine said is enough to power more than 500,000 homes. It can also provide steam for nearby industrial purposes.

The project anticipates creating construction and other full-time jobs, with engineering, permitting, and other development activities coming soon.

"We’re thrilled to work with Calpine on this project that supports American energy security, enhances industrial competitiveness and leverages America’s abundant low-cost natural gas resources," Barry Engle, President of ExxonMobil Low Carbon Solutions, said in a news release. “This agreement underscores the growing confidence our customers across diverse sectors—including steel, fertilizer, industrial gases, natural gas processing, and now power generation—have in our unique end-to-end CCS system.”

This is ExxonMobil’s sixth CCS customer, bringing the company's total amount of CO2 under contract to approximately 16 million tons a year, according to the company. The CO2 from Calpine’s facility will tie into ExxonMobil’s CO2 pipeline system on the Gulf Coast.

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.
