UC Berkeley researchers say they have found a better way to make natural gas power plants emit less carbon dioxide, a tool they hope can help fight climate change even while California tries to shift to renewable energy. Working with ExxonMobil, the Berkeley researchers identified a new technique that they say can catch about 90% of the planet-warming carbon dioxide emitted from a gas-burning plant and is six times more effective than the method currently used. For more on this, see our press release at Berkeley News.
