US oil giant Chevron has pledged to invest $25 million in a green waste-to-hydrogen project in California aiming to supply hydrogen to refuelling depots for transport.

The $50 million plant in Richmond, northern California, will be designed to handle 99 wet tonnes of organic (food and green) waste diverted from a local landfill, producing 2400 tonnes per annum of hydrogen.

Green fuels start-up Raven will operate the facility as part of a joint venture which includes Chevron and troubled hydrogen fuel cell (FCEV) truckmaker Hyzon Motors, currently under investigation by US regulators after failing to report financial results.
