LCG, April 24, 2025--Exxon Mobil Corporation (ExxonMobil) announced yesterday an agreement with Calpine Corporation (Calpine) to transport and permanently store up to 2 million metric tons per annum (MTA) of CO2 from Calpine’s Baytown Energy Center, a natural gas-fired facility located near Houston, Texas. This is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project that is designed to add CCS for the facility’s CO2 emissions. The Calpine facility could then provide a 24/7 supply of low-carbon electricity to the Texas grid plus steam to nearby industrial facilities.

Calpine and ExxonMobil Sign CO2 Transportation and Storage Agreement for CCS Project in Texas
LCG, April 24, 2025--Exxon Mobil Corporation (ExxonMobil) announced yesterday an agreement with Calpine Corporation (Calpine) to transport and permanently store up to 2 million metric tons per annum (MTA) of CO2 from Calpine’s Baytown Energy Center, a natural gas-fired facility located near Houston, Texas. This is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project that is designed to add CCS for the facility’s CO2 emissions. The Calpine facility could then provide a 24/7 supply of low-carbon electricity to the Texas grid plus steam to nearby industrial facilities.
This new agreement marks ExxonMobil’s sixth CCS customer, bringing the company’s total amount of CO2 under contract to ~16 MTA. The CO2 emissions from Calpine’s facility will flow into ExxonMobil’s extensive CO2 pipeline system that is strategically located along the U.S. Gulf Coast and supports enhanced oil recovery as well as permanent CO2 sequestration sites.
Calpine's existing Baytown Energy Center is located on a 24-acre campus and consists of three combustion turbines with three heat recovery steam generators (HRSGs) that produce 810 MW of base load electric power. Once the Calpine Baytown CCS Project is completed, the facility will be a very low-carbon cogeneration facility that is expected to produce about 500 MW of electricity plus steam for co-located industrial facilities. Engineering, permitting, and other development activities are underway.
The U.S. Department of Energy’s Office of Clean Energy Demonstrations (OCED), which has a mission to accelerate and deliver clean energy demonstration projects at scale in partnership with the private sector, last year selected three CCS projects to begin award negotiations for a total of up to $890 million. In July, OCED awarded the Baytown Carbon Capture and Storage Project $12.5 million of federal funding (of the total federal cost share of up to $270 million) to begin activities in Phase 1, which had a 9-12 month timeline at the time.
The President of ExxonMobil Low Carbon Solutions stated, "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. 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.”
“Calpine is excited to partner with ExxonMobil to achieve this important project milestone,” said Calpine's Executive Vice President. “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."
“We’re grateful to the Trump administration for championing expanded energy and electricity production to power America’s economy and to the Department of Energy for its longstanding role in power sector and CCS technology advancement. This support has allowed us to expand our investments in power infrastructure including our recently acquired Quail Run Energy Center in the Permian as well as additional generation and storage projects across the country. We believe we are on the brink of commercializing CCS technology,” said Calpine's Executive Vice President.
The advancement of this project remains contingent on ongoing supportive government policy, customer power sales agreements, and receipt of necessary regulatory permits.
ExxonMobil and Calpine mergers and acquisitions appear to be aligned with the CCS project. ExxonMobil announced back in November 2023 that it had closed its acquisition of Denbury Inc., which included a large CO2 pipeline network. With the acquisition, ExxonMobil stated at the time that it had the largest owned and operated CO2 pipeline network in the U.S. – adding more than 1,300 miles, including nearly 925 miles of CO2 pipelines in Louisiana, Texas and Mississippi – located in one of the largest U.S. markets for CO2 emissions. Furthermore, ExxonMobil stated it has access to more than 15 strategically located onshore CO2 storage sites.
Calpine and Constellation Energy announced in January that they have entered into a definitive agreement under which Constellation will acquire Calpine. According to the announcement, the agreement creates the nation’s largest clean energy provider, opening opportunities to serve more customers coast-to-coast with a broader array of energy and sustainability products. Constellation, with its large nuclear fleet, claims (i) to be the nation’s largest producer of 24/7 emissions-free electricity, and (ii) that Calpine is the largest U.S. producer of energy from low-emission natural gas generation and an expanded renewable energy portfolio, including the largest geothermal generation operation in the U.S. Thus there will be many existing fossil fueled power plants owned by the combined fleet of Constellation and Calpine for consideration of CCS applications.
