Zero Emission Industries has been through all the paces of putting a hydrogen power system in a ship.

Now, with the financial backing of big-name investors, the California technology company wants to make sure its customers do not have to go through that.

ZEI chief executive Joe Pratt told TradeWinds that, after completing the first hydrogen-fuelled ferry in the US, the company is planning to roll out the next generation of its hydrogen power system after investments from energy giant Chevron and shipping outfit Crowley.
