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.

EPA Creates New Hurdle for Proposed Desert Rock Coal Plant
LCG, April 28, 2009--The Environmental Protection Agency (EPA) yesterday filed for a "complete remand" of a prior air permit - issued by the EPA - for the 1,500-MW Desert Rock Energy Facility to be built in Navajo Nation lands in the Four Corners area. The Environmental Appeals Board, an EPA organization, will now decide if the permit issued will be sent back to the EPA's Pacific Southwest office for further review.
The proposed coal-fired, electric generating facility is a joint venture of Desert Rock Energy Company, a subsidiary of Sithe Global Power LLC., and Dine Power Authority, an enterprise of the Navajo Nation.
The EPA issued an air permit on July 31, 2008 for the Desert Rock Energy Facility. The receipt of an air permit was a key milestone for the project. The application for the air permit was submitted in early 2004, and the EPA has one year to issue a decision by law. Sithe and Dine Power Authority sued the EPA in March 2008, claiming that the EPA was delaying the permit.
The estimated cost of the Desert Rock Energy Facility is approximately $3 billion. The project includes two, 750-MW, super-critical boilers, and the estimated heat rate for facility is 8,792 Btu/kWh (net, higher heating value basis). The coal supply will be low sulfur, sub-bituminous coal from the Navajo Nation.
