Zero Emission Solutions for Ships

This is a TOOL feature list that provides an overview of a specific focus area. Find out more about feature lists here.

Global overview of zero emission ship technologies & projects for the maritime industries. The actors include ship technology providers, ship owners, maritime service providers, institutions, and associations that pioneer specific solutions & projects fueling the decarbonization of maritime industries.

This featured list is regularly updated by the TOOL team. We would like to acknowledge our resource partners Cleantech Matters, Furstenberg Maritime Advisory and ZESTAS as key sources for solution providers. Note that the actors & solutions are not vetted by TOOL, this feature is simply a broad overview.

NOTE: This list excludes biofuels, methanol, and ethanol, as well as petroleum based solutions as blue/grey hydrogen - as it focuses on well-to-wake zero-emission fuels.
