Global miner Rio Tinto said it will focus the majority of its investment in carbon capture and storage (CCS) technology on the proposed new hydrogen-powered electricity facility in California, US.

The Hydrogen Energy California HECA project, which is a joint venture with energy giant BP, will produce clean electricity.

Rio said the facility aims to produce greenhouse gas emissions lower than the cleanest natural gas power plants.

The facility will generate power for over 150,000 homes with a 90% reduction in CO2 emissions.

Rio Tinto’s Technology & Innovation group executive Preston Chiaro said that the California project will use coal or petcoke as a feedstock.
