ExxonMobil breaks ground on Texas carbon dioxide storage project

ExxonMobil announced this month that it has officially broken ground on a groundbreaking carbon dioxide storage site.

According to a release from the company, a new rig is currently being used to gather information about an underground site in Southeast Texas. The rig stands 225 feet tall, but more importantly extends 8,000 feet below the subsurface to investigate if the site is a safe place to store carbon underground.

“Everyone’s excited about this appraisal well because we’re literally breaking ground on a new chapter of our work to help reduce industrial emissions,” Joe Colletti, who oversees carbon capture and storage development along the Gulf Coast for Exxon, says in a statement.

Exxon plans to move the rig to other sites in the Gulf Coast in the future for clients Nucor Corp., CF Industries and Linde.

In the last year, Exxon has made agreements with these regional companies to store carbon captured from their operations.

  • Exxon agreed to transport and permanently store up to 2.2 million metric tons of carbon dioxide each year from Linde’s hydrogen production facility in Beaumont, Texas when it launches in 2025.
  • Exxon agreed to store up to 2 million metric tons per year of CO2 captured from CF Industries’ ammonia plant in Donaldsonville, Louisiana, starting in 2025.
  • Exxon agreed to capture, transport and store up to 800,000 metric tons per year of CO2 from Nucor’s direct reduced iron manufacturing site in Convent, Louisiana starting in 2026.

Together, the three agreements represent a total of 5 million metric tons per year that Exxon plans to transport and store for third-party customers.

“Our agreement with Nucor is the latest example of how we’re delivering on our mission to help accelerate the world's path to net zero and build a compelling new business,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a statement over the summer. “Momentum is building as customers recognize our ability to solve emission challenges at scale.”

In addition to the carbon storage agreements, the energy giant also completed the acquisition of Denbury Inc. this month in an all-stock transaction valued at $4.9 billion. The deal adds more than 1,300 miles, including nearly 925 miles of CO2 pipelines in Louisiana, Texas and Mississippi to Exxon's CO2 pipeline network.

The deal was first announced this summer.

Houston-based geothermal energy company Fervo Energy has closed an oversubscribed $462 million series E funding round, led by new investor B Capital.

“Fervo is setting the pace for the next era of clean, affordable, and reliable power in the U.S.,” Jeff Johnson, general partner at B Capital, said in a news release. “With surging demand from AI and electrification, the grid urgently needs scalable, always-on solutions, and we believe enhanced geothermal energy is uniquely positioned to deliver. We’re proud to support a team with the technical leadership, commercial traction, and leading execution capabilities to bring the world’s largest next-generation geothermal project online and make 24/7 carbon-free power a reality.”

The financing reflects “strong market confidence in Fervo’s opportunity to make geothermal energy a cornerstone of the 24/7 carbon-free power future,” according to the company. The round also included participation from Google, a longtime Fervo Partner, and other new and returning investors like Devon Energy, Mitsui & Co., Ltd., Mitsubishi Heavy Industries and Centaurus Capital. Centaurus Capital also recently committed $75 million in preferred equity to support the construction of Cape Station Phase I, Fervo noted in the release.

The latest funding will support the continued buildout of Fervo’s Utah-based Cape Station development, which is slated to start delivering 100 MW of clean power to the grid beginning in 2026. Cape Station is expected to be the world's largest next-generation geothermal development, according to Fervo. The development of several other projects will also be included in the new round of funding.

“This funding sharpens our path from breakthrough technology to large-scale deployment at Cape Station and beyond,” Tim Latimer, CEO and co-founder of Fervo, added in the news release. “We’re building the clean, firm power fleet the next decade requires, and we’re doing it now.”

Fervo recently won Scaleup of the Year at the 2025 Houston Innovation Awards, and previously raised $205.6 million in capital to help finance the Cape Station earlier this year. The company fully contracted the project's capacity with the addition of a major power purchase agreement from Shell this spring. Fervo’s valuation has been estimated at $1.4 billion and includes investments and support from Bill Gates.

“This new investment makes one thing clear: the time for geothermal is now,” Latimer added in a LinkedIn post. “The world desperately needs new power sources, and with geothermal, that power is clean and reliable. We are ready to meet the moment, and thrilled to have so many great partners on board.”
