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.

Cow Power

LCG, March 15, 2002--Energy Northwest considers manure as a viable source of electricity.

The public power provider has been investigating the possibility of using methane from dairy cows to power a 3 or 4 megawatt power plant. Cows in Washington, Oregon, and Idaho may be involved with producing "biogas;" the northwest constitutes eight percent of U.S. dairy production.

Right now cows can produce a little less than a third of a kilowatt per cow, although some studies report up to nine-tenths of a kilowatt. Naturally occurring bacteria produces the methane from manure and can be put to efficient use by mixing manure and water in a tank at elevated temperatures (130 F). Methane gas rises from the liquid and is ready to be combusted in a modified diesel generator.

While the fuel may be free, a methane plant will cost almost three times as much per kilowatt as wind power. Energy Northwest business developer Stan Davison said that the cost is justified because manure-powered plants can operate at 90 percent, instead of the 30 percent that wind yields yearly.

Energy Northwest has yet to find investors for the project.
