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.

APS Plans a 280-MW Solar Power Plant

LCG, February 22, 2008--Arizona Public Service Co. (APS) yesterday announced plans for the construction of a 280-MW concentrating solar power (CSP) plant in Arizona. The Solana Generating Station will be builtapproximately 70 miles southwest of Phoenix and is scheduled to commence operations by 2011. The design capacity of the planned facility is greater than any solar facility operating today.

Abengoa Solar Inc. will build, own and operate the plant, and APS will purchase all of the power generated, subject to approval by the Arizona Corporation Commission.

The Solana Generating Station will use parabolic mirrors to track the sun and concentrate the sun's energy on a heat transfer fluid, which will obtain temperatures greater than 700 degrees Fahrenheit. The fluid will in turn be used to transform water into steam for a steam turbine that creates power. The mirrors will cover an area of about 1,900 acres.

To provide operating flexibility, the facility will incorporate a thermal energy storage system that allows for electricity to be produced as required, even at night.

In December of last year, the U.S. Air Force announced that operations hadcommenced for North America's largest solar photovoltaic system that is capable of generating 14 MW. The solar project, located at Nellis Air Force Base in Nevada, covers 140 acres.
