A subsidiary of Houston-based energy company Occidental has snagged a roughly $600 million federal grant to establish a hub south of Corpus Christi that’ll remove carbon emissions from the air.

The U.S. Department of Energy’s Office of Clean Energy Demonstrations grant, awarded to Occidental subsidiary 1PointFive, will go toward building the South Texas Direct Air Capture (DAC) Hub. It’ll be located on about 106,000 leased acres within a Kleberg County site at the iconic King Ranch. The hub will comprise 30 individual DAC projects.

In a news release, Occidental says the facility will be able to pull at least 1 million metric tons of carbon from the air each year. The hub eventually might remove and store up to 30 million metric tons of CO2 per year, the company says.

The hub initially will create about 2,500 jobs in construction, operations, and maintenance, says Occidental.

Direct air capture removes CO2 from the atmosphere at any location, according to the International Energy Agency. That’s opposed to carbon capture, which generally happens where CO2 is emitted. Either way, the carbon is stored in deep geological formations and used for a variety of purposes, such as making concrete.

In the case of the South Texas hub, carbon dioxide that’s captured and stored will come from industrial sites along the Texas Gulf Coast.

Occidental President and CEO Vicki Hollub says the grant from the U.S. Department of Energy “validates our readiness, technical maturity, and the ability to use Oxy’s expertise in large projects and carbon management to move the technology forward so it can reach its full potential.”

Oxy’s partners in the South Texas project include:

  • Canada-based clean energy company Carbon Engineering
  • Australia-based professional services provider Worley
  • DOE’s Lawrence Livermore National Laboratory in Northern California
  • Livermore Lab Foundation
  • Texas A&M University-Kingsville
  • Coastal Bend Bays & Estuaries Program in Corpus Christi
  • University of Texas at Austin Gulf Coast Carbon Center

The South Texas DAC Hub was one of two DAC projects awarded as much as $1.2 billion in funding August 11 by the Department of Energy (DOE). The other project is Project Cypress, located in Louisiana’s Calcasieu Parish; it received up to $603 million in funding.

In announcing the DAC funding, U.S. Energy Secretary Jennifer Granholm says her agency “is laying the foundation for a direct air capture industry crucial to tackling climate change — transforming local economies and delivering healthier communities along the way.”

The DOE says the Texas and Louisiana projects represent the world’s largest-ever investment in engineered carbon removal. They’re two of the four regional projects that the DOE plans to finance as part of its DAC initiative, supported by $3.5 billion in federal funding aimed at capturing and storing pollution from carbon dioxide.

Just 18 DAC facilities are currently operating across the U.S., Canada, and Europe, according to a 2022 report from the International Energy Agency.

“No matter how fast we decarbonize the nation’s economy, we must tackle the legacy pollution already in our atmosphere to avoid the worst effects of climate change,” Granholm said in 2022.

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
