Expanding on its partnership with the United States Department of Defense's Defense Innovation Unit, Sage Geosystems has been selected to conduct geothermal project development initiatives at Naval Air Station in Corpus Christi.

Along with the Environmental Security Technology Certification Program, Sage will provide its proprietary Geopressured Geothermal Systems technology, will be able to evaluate the potential for geothermal baseload power generation to provide clean and consistent energy at the Naval Air Station base.

“We’re pleased to expand our partnership with the DOD at NAS Corpus Christi to demonstrate the advantages of geothermal technology for military energy independence,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

Sage is also conducting initiatives at Fort Bliss and has completed an analysis at the Ellington Field Joint Reserve Base. The analyses could “pave the way for expanding geothermal energy solutions across additional U.S. military installations,” according to Sage.

The company’s proprietary technology works by leveraging hot dry rock, which is a more abundant geothermal resource compared to traditional hydrothermal formations, and it provides energy resilience for infrastructures. In addition, Sage is building a 3 megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, which is expected to be completed by December. Sage also announced a partnership with Meta Platforms. With Meta Platforms, Sage will deliver up to 150 megawatt of geothermal power generation east of the Rocky Mountains.

The Naval Air Station Corpus Christi is considered a critical training and operations hub for the U.S. Navy, and the partnership with Sage shows the Navy's commitment to achieving net-zero carbon emissions by 2045. Sage’s technology will be assessed for its ability to create a microgrid, which can reduce reliance on the utility grid and ensure power supply during outages.

“As we advance our Geopressured Geothermal Systems, we see tremendous potential to not only provide carbon-free power, but also strengthen the operational capabilities of U.S. military installations in an increasingly digital and electric world,” Taff adds.

In September, the Air Force awarded Sage a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy needed for a base to achieve energy resilience.

US Air Force awards Houston geothermal co. $1.9M grant project

big deal

The Department of the Air Force awarded Houston geothermal company Sage Geosystems Inc. a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy “needed for a base to achieve energy resilience,” according to a news release. The Sage facility will be the first GGS facility in the world to generate electricity, and the system will be constructed at an off-site test well in Starr County, Texas.

”We are excited to partner with the U.S. Air Force on this geothermal demonstration project,” CEO of Sage Geosystems Cindy Taff says in a news release. “Next generation geothermal technologies, like Sage Geosystems’ GGS, will be critical in providing energy resiliency at U.S. military installations.”

In addition to the grant, the company will match the grant with an additional $1.9 million for the demonstration project. The collaboration with Sage is one of three geothermal pilot projects the DAF has initiated in regards to next-generation geothermal technologies in 2024.

“We feel this is the launch pad of helping not only the DoD but many other applications throughout global markets,” 147th Civil Engineer Squadron Commander Lt Col Christian Campbell says in the release.

According to the DAF, the possibility of a full-scale project at Ellington Field Joint Air Reserve Base in Houston could usher in a new era of clean power producing plants to help meet the requirements for bases.

“This initial contract is a step forward in the Air Force’s push for energy resilience,” Kirk Phillips, director of the Air Force Office of Energy Assurance, adds in the release. “This project will improve Ellington Field’s ability to maintain operations during electrical grid outages and be completely self-sufficient for their energy needs.”

The GGS process works by repurposing fracking technology to extract thermal energy from below the Earth’s surface.GGS also demonstrates the opportunity for the civilian sector by surpassing the intermittency challenges for solar and wind energy generation. GSS can also work towards minimizing land use, which enables the technology to be used in urban areas without relying on transmission line build outs that can be expensive.

“This project, and the future Department of the Air Force projects that it paves the way for, will help to assure that our national security needs are met by our installations during critical emergencies,” Phillips continues.

DOE taps Texas companies for $56M in Strategic Petroleum Reserve deliveries

reserve refill

Two companies with ties to the Houston area have been awarded federal contracts totaling nearly $55.8 million to supply about 1 million barrels of crude oil for the nation’s depleted Strategic Petroleum Reserve.

Houston-based Trafigura Trading will provide two-thirds of the oil, and Dallas-based Energy Transfer Crude Marketing will provide the remaining one-third. Energy Transfer, the parent company of Energy Transfer Crude Marketing, operates a 330-acre oil terminal at the Houston Ship Channel.

The U.S. Department of Energy (DOE), which awarded the contracts, said Trafigura and Energy Transfer will deliver the crude oil from Dec. 1 through Jan. 31 to the Strategic Petroleum Reserve’s Bryan Mound storage site near Freeport.

The Strategic Petroleum Reserve, the world’s largest emergency supply of crude oil, can hold up to 714 million barrels of crude oil across 61 underground salt caverns at four sites along the Gulf Coast. The reserve currently contains 410 million barrels of crude oil. During the pandemic, the Biden administration ordered a 180 million-barrel drawdown from the reserve to help combat high gas prices triggered by Russia’s war with Ukraine.

The four strategic reserve sites are connected to 24 Gulf Coast refineries, and another six refineries in Kentucky, Michigan and Ohio.

“Awarding these contracts marks another step in the important process of refilling this national security asset,” U.S. Energy Secretary Chris Wright said.

In March, Wright estimated it would take $20 billion and many years to fill the Strategic Petroleum Reserve to its maximum capacity, according to Reuters

What EPA’s carbon capture and storage permitting announcement means for Texas

The View From HETI

Earlier this month, Texas was granted authority by the federal government for permitting carbon capture and storage (CCS) projects. This move could help the U.S. cut emissions while staying competitive in the global energy game.

In June, the U.S. Environmental Protection Agency (EPA) proposed approving Texas’ request for permitting authority under the Safe Drinking Water Act (SDWA) for Class VI underground injection wells for carbon capture and storage (CCS) in the state under a process called “primacy.” The State of Texas already has permitting authority for other injection wells (Classes I-V). In November, the EPA announced final approval of Texas’ primacy request.

Why This Matters for Texas

Texas is the headquarters for virtually every segment of the energy industry. According to the U.S. Energy Information Administration, Texas is the top crude oil- and natural-gas producing state in the nation. The state has more crude oil refineries and refining capacity than any other state in the nation. Texas produces more electricity than any other state, and the demand for electricity will grow with the development of data centers and artificial intelligence (AI). Simply put, Texas is the backbone of the nation’s energy security and competitiveness. For the nation’s economic competitiveness, it is important that Texas continue to produce more energy with less emissions. CCS is widely regarded as necessary to continue to lower the emissions intensity of the U.S. industrial sector for critical products including power generation, refining, chemicals, steel, cement and other products that our country and world demand.

The Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) has supported efforts to bring CCUS to a broader commercial scale since the initiative’s inception.

“Texas is uniquely positioned to deploy CCUS at scale, with world-class geology, a skilled workforce, and strong infrastructure. We applaud the EPA for granting Texas the authority to permit wells for CCUS, which we believe will result in safe and efficient permitting while advancing technologies that strengthen Texas’ leadership in the global energy market,” said Jane Stricker, Executive Director of HETI and Senior Vice President, Energy Transition at the Greater Houston Partnership.

What is Primacy, and Why is it Important?

Primacy grants permitting authority for Class VI wells for CCS to the Texas Railroad Commission instead of the EPA. Texas is required to follow the same strict standards the EPA uses. The EPA has reviewed Texas’ application and determined it meets those requirements.

Research suggests that Texas has strong geological formations for CO2 storage, a world-class, highly skilled workforce, and robust infrastructure primed for the deployment of CCS. However, federal permitting delays are stalling billions of dollars of private sector investment. There are currently 257 applications under review, nearly one-quarter of which are located in Texas, with some applications surpassing the EPA’s target review period of 24 months. This creates uncertainty for developers and investors and keeps thousands of potential jobs out of reach. By transferring permitting to the state, Texas will apply local resources to issue Class VI permits across the states in a timely manner.

Texas joins North Dakota, Wyoming, Louisiana, West Virginia and Arizona with the authority for regulating Class VI wells.

Is CCS safe?

A 2025 study by Texas A&M University reviewed operational history and academic literature on CCS in the United States. The study analyzed common concerns related to CCS efficacy and safety and found that CCS reduces pollutants including carbon dioxide, particulate matter, sulfur oxides and nitrogen oxides. The research found that the risks of CCS present a low probability of impacting human life and can be effectively managed through existing state and federal regulations and technical monitoring and safety protocols.

What’s Next?

The final rule granting Texas’ primacy will become effective 30 days after publication in the Federal Register. Once in effect, the Texas Railroad Commission will be responsible for permitting wells for carbon capture, use and storage and enforcing their safe operation.
