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 and Starwood Plan 290-MW Solar Project in Arizona

LCG, May 27, 2009--Arizona Public Service (APS) and Starwood Energy Group Global plan to construct a 290-MW concentrating solar plant (CSP) near Phoenix, Arizona. The Starwood Solar I plant is scheduled to be operational in 2013.

The facility will be designed, built and operated by Lockheed Martin, and it will be owned by an affiliate of Starwood Energy. APS will buy all of the electricity generated through a long-term purchase power agreement (PPA).

Starwood Solar I will employ a concentrated solar design that reflects solar energy with parabolic mirrors onto tubes filled with liquid. The heated liquid is used to convert water into steam that drives steam turbines that drive a generator.

The project includes a thermal storage system of molten salt to provide energy for power generation when direct solar energy is inadequate, which enables the plant to be dispatched when the sun is not shining. The project footprint covers a 1,900-acre site.
