About C-Zero

C-Zero is a hard-tech startup located in Santa Barbara, CA, that is developing a technology for decarbonizing natural gas. The company’s technology uses high temperatures to break down methane, (the primary molecule in natural gas) into hydrogen and solid carbon. C-Zero’s hydrogen can be used to decarbonize a wide range of industries including ammonia production, gasoline and diesel fuel, electric generation, process heat, and fuel cell vehicles, and has the potential to address 75% of global CO2 emissions.
