Greentech Media: Novel Power-to-Gas Tech Begins Testing in the US

Last month, a team of researchers and engineers quietly installed a first-of-its-kind energy reactor on the campus of a government lab just west of Denver, Colorado. The device — a 25-foot-tall, thin mass of industrial silver pipes and tanks — is a test of a rather unusual method to store energy using microbes, hydrogen and clean electricity. Similar technology is being tested in pilot projects across Europe, but the reactor in Colorado is one of the only ones operating within the U.S. If the process, known as “power-to-gas” by those in the industry, is able to be deployed at a bigger scale and at a lower cost it could some day offer a solution to store large amounts of electricity produced by wind and solar over long periods of time.
