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.

Duke's Plans for Battery Storage System Gain Momentum

LCG, April 15, 2011--Duke Energy Renewables will employ a $44 million dollar, 36-MW battery storage system to support its 153-MW, Notrees Wind Project located in west Texas. Duke's spokesperson stated that it will be the world?s largest power storage system for a wind farm after it is installed late next year.

Duke selected Xtreme Power, a manufacturer of large-scale developer of digital power systems, to design, install and operate the battery storage system. The project is funded in part by a $22 million grant from the U.S. Department of Energy (DOE).

The Notrees Wind Project commenced service in April 2009. The first phase of the project is rated at 90 MW and includes 55 Vestas turbines that operate at 1.65 MWs each; the second phase is rated at 60 MW and includes forty, 1.5-MW General Electric turbines.

The Duke spokesperson stated, "In addition to supplying stored renewable energy, this battery storage system will be capable of providing other key grid services, including helping smooth out the frequency of electricity traveling throughout the power grid....One of the key intents of this energy storage project is to test and demonstrate how that added flexibility can benefit renewable-power projects throughout the country."

The Electric Power Research Institute (EPRI) will support the project team and collect data to evaluate other potential grid applications.
