This summer, researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) are testing technology that could help reduce fuel consumption by 20-25% in natural gas power plants. This technology uses natural gas + sunlight to create syngas. More specifically, the heat from a concentrating solar power (CSP) system to break the chemical bonds in natural gas. This creates a fuel (syngas) comprised primarily of carbon monoxide (CO) and hydrogen (H2).
