ExxonMobil will transport and permanently store up to 2 million metric tons per annum (MMtpa) of carbon dioxide (CO2) captured at Calpine’s Baytown Energy Center near Houston, the companies announced April 23.
The CO2 from Calpine’s facility, which will be able to produce up to about 500 MW of low-carbon electricity and also supply steam for nearby industrial use, will tie into ExxonMobil’s existing CO2 pipeline system along the Gulf Coast. Total generating capacity at the site is 810 MW.
The carbon-capture project received $12.5 million in federal funding last year from the Department of Energy’s Office of Clean Energy Demonstrations (OCED), which said it would be the first full-scale implementation of carbon-capture technology at a natural gas combined-cycle power plant in the U.S.
It is the sixth carbon capture and sequestration (CCS) customer for ExxonMobil, bringing the company’s total amount of CO2 under contract to about 16 MMtpa.
The companies said the project remains contingent on ongoing supportive government policy, customer power sales agreements, and permitting.
