Project partners

SEA-KIT International will partner with maritime decarbonisation disruptor, Marine2o, for the build of land-based infrastructure to produce green hydrogen, via renewable energy and the electrolysis of water, as part of the project. 


Engineering design and sustainability specialists, Marine Zero, will support all partners with regulatory compliance and and Marine2o with the design and integration of the dispensing facility.


The Port of London Authority (PLA), a consortium partner, will host the hydrogen refilling station on the River Thames in London and subsequently operate the ZEPHR USV during the three year demonstration period.



ZEPHR, funded through the ZEVI competition, leads the way to a net zero future. The project encompasses the design, manufacture and operation of a green hydrogen fuelled Uncrewed Surface Vessel (USV), to be operated on the River Thames in London, and local green hydrogen production and storage.

Read the project announcement press release.

ZEPHR aims to extend vessel operation ranges for port operators and stakeholders through complete energy transferal, from readily accessible green electricity to 100% green hydrogen production, compression, storage and dispensing.


The project runs from 1 October 2023 to 31 March 2025 and will be followed by a vessel demonstration period of at least three years in an operational environment.
