“We’ve Got the Power”: Sandia technology test delivers electricity to the grid

August 9, 2022 – 5:00 am

ALBUQUERQUE, N.M. — For the first time, Sandia National Laboratories researchers delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. The Brayton cycle is named after 19th […]

‘I’m melting, melting’ — environmentally hazardous coal waste diminished by citric acid

October 25, 2021 – 5:00 am

ALBUQUERQUE, N.M. — In one of nature’s unexpected bounties, a harmless food-grade solvent has been used to extract highly sought rare-earth metals from coal ash, reducing the amount of ash without damaging the environment and at the same time increasing an important national resource. Coal ash is the unwanted but widely present residue of coal-fired […]

New fractal-like concentrating solar power receivers are better at absorbing sunlight

October 25, 2017 – 5:00 am

ALBUQUERQUE, N.M. — Sandia National Laboratories engineers have developed new fractal-like, concentrating solar power receivers for small- to medium-scale use that are up to 20 percent more effective at absorbing sunlight than current technology. The receivers were designed and studied as part of a Laboratory Directed Research and Development project and are also being applied […]
