Sandia successfully tests heat-powered system
August 21, 2023 • ALBUQUERQUE, N.M. — Capturing carbon dioxide and pumping it deep underground could be an important part of mitigating the effects of climate change. However, ensuring the carbon dioxide stays trapped away from the atmosphere, where it serves as a heat-trapping greenhouse gas, is critical. Researchers at Sandia National Laboratories recently...
