EPA and Texas Railroad Commission Sign Memorandum of Agreement for Permitting Geologic Storage of Carbon Dioxide

LCG, April 29, 2025--Officials from the U.S. Environmental Protection Agency (EPA) and Texas Railroad Commission (RRC) signed a memorandum of agreement (MOA) today outlining the state’s plans to administer programs related to carbon storage wells, known as Class VI wells. The MOA signing is a required step in the RRC’s application to be granted authority to permit Class VI wells in the state of Texas. EPA is currently preparing a proposed approval of RRC’s primacy application.

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.

DOE Selects Tampa Electric Site for Carbon Capture Project Grant

LCG, July 20, 2010--The Department of Energy (DOE) selected Tampa Electric's Big Bend Station for a carbon capture project that will receive an $8.9 million grant. This pilot plant was one of ten selected by the DOE to improve efficiencies and lower costs for carbon capture technologies employed at coal-fired power plants.

The project will demonstrate new POSTCAP technology that uses an amino acid salt as a solvent for CO2 absorption. Siemens Energy will design, install, and operate a pilot plant to capture 90 percent of the CO2 from a slipstream (1 MW equivalent) of the post-combustion exhaust gas. The flue gas will be extracted downstream of an existing Siemens Wet FGD system. A benefit of using the non-toxic, biodegradable solvent is a more environmentally friendly process.

The pilot project is scheduled to commence operations in 2013. Siemens began operations of its first pilot CO2 capture plant for coal-fired power plants at the Staudinger power plant in Germany in September 2009.
