Chevron’s New Energies business unit and US-based shipping and logistics company Crowley have invested in maritime hydrogen technology company Zero Emission Industries (ZEI).
Launched in 2017, ZEI, formerly Golden Gate Zero Emission Marine, develops and sells power systems for a range of marine applications. It is best known for the Sea Change, the first commercial hydrogen fuel cell ferry in the world.
The new undisclosed funds raised in a Series A funding round are expected to enable ZEI to roll out its fully integrated marine power system and scale quickly to meet the demand within the maritime industry for their zero emission propulsion solutions.
ZEI said the investments from Chevron and Crowley create an integrated value chain from hydrogen production to power systems to vessels. The company added that this collaboration would drive value for end users and partners alike through simplified and “cost-effective fueling and power solutions made specifically for maritime”.
