Clean Maritime Demonstration Competition Round 3 (CMDC3)

Maritime decarbonization technology

Port operations

Maritime services

Technology developed by Waterwhelm that converts effluent from wastewater treatment plants into reusable water for hydrogen production, achieving the lowest-ever rate of electricity consumption and carbon emissions for water reuse systems.

Portable infrastructure developed by Unitrove for refueling hydrogen-powered vessels at port locations; claimed to be the world's first of its kind.

An uncrewed cargo ship capable of operating without human crew, integrated with hydrogen fuel systems for zero-emission maritime transport.

Scotland

England

An uncrewed maritime surface vessel powered by liquid hydrogen fuel, designed to transport cargo autonomously. Claimed to be the world's first of its kind.

Portable infrastructure for storing and dispensing liquid hydrogen to hydrogen-powered vessels at port locations. Unitrove claims this is the world's first liquid hydrogen bunkering facility.

A generator that uses hydrogen fuel to produce clean electricity for shore power supply to docked vessels, with water vapor as the only emission.
