Hydrogen technology start-up Zero Emission Industries (ZEI) has scored investments from Crowley and energy major Chevron.

The Series A funding round is expected to help the company roll out its pioneering hydrogen marine power systems for shipping, as well as pump up its scale to meet demand for zero-emission propulsion solutions in shipping.

ZEI is the developer of the 75-passenger Sea Change, the first hydrogen fuel cell-powered ferry in the US.
