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.

New Materials May Make Capacity Upgrades of Lines Easier

LCG, Mar. 4, 2004--Composite materials are being tested in newly designed power lines that have the advantages of not sagging like traditional lines, and of allowing a greater amount of power to flow without adding significant bulk.

Companies developing the lines use substitutes for the steel that makes up the central core of traditional power cables, around which aluminum stands used to transmit electricity are wrapped. Because the composite materials, which use carbon fiber, glass and epoxy, provide the same strength as steel cores with larger diameters, they make it possible to wrap more aluminum around lines' cores. At the same time, they conduct less than steel, and sag up to 90% less, their makers say. This latter feature could be useful in preventing blackouts due to lines that heat up, and come to rest on trees or the ground.

The largest-scale test yet underway is planned by a local utility in Kingman, Kan., which has agreed to pay for a test of a 21-mile-long line, according to the New York Times. Other tests are underway in North Dakota and Minnesota, where another company will see how well its line performs in the local weather conditions. The Department of Energy is contributing financial assistance to a test near Fargo, N.D., scheduled for the winter. If the tests are considered successful, more widespread adoption will depend on the willingness of utilities to replace older lines, which can operate for more than 50 years without becoming seriously degraded.
