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.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.

3 Houston-area companies named to Global Cleantech 100

Energized

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023.
