Project: Hydrogen in an Integrated Maritime Energy Transition (HIMET)

Funder: Department for Transport in partnership with Innovate UK via the Clean Maritime Demonstration Competition

Funding: : £2.2 million

Project Overview:

The £2.2 million HIMET (Hydrogen in an Integrated Maritime Energy Transition) project will explore solutions for decarbonising ferries as well as shore-side activities in ports.

Led by EMEC Hydrogen in Orkney, HIMET will progress an ambitious programme of activities centred around the decarbonisation of two key local maritime sectors: ferry services and cruise terminal operations.

To decarbonise ferries, various solutions will be designed and demonstrated. A containerised hydrogen storage solution designed specifically for use on board a vessel will be demonstrated on the deck of the MV Shapinsay in addition to a hydrogen fuel cell to supply auxiliary power. The containerised hydrogen storage and the fuel cell will be tested as a standalone system. Separate to the on-board demonstration, a conventional ferry propulsion engine retrofitted to run on pure hydrogen will also be tested by project partner Ricardo at a dedicated test facility in Shoreham. The aim of these separate activities is to demonstrate the step-by-step application of hydrogen on-board a passenger ferry to support the technical, practical and regulatory development for decarbonised ferry services.

To support the development resilient, decarbonised shore-side power for the maritime sector, a hybrid solar PV and hydrogen engine will be deployed at Hatston Pier in Orkney to power crew welfare facilities at the cruise terminal. Microgrid solutions for the Kirkwall harbour will also be studied to consider future power requirements for harbours.

Additionally, HIMET will carry out research and stakeholder engagement activities to establish how decarbonised fuels (hydrogen and ammonia) coupled with technology innovations can best inform the broader maritime energy transition and help overcome regulatory barriers.

All of the project activities in HIMET have been conceived with this intention to build the evidence base required to support the development of the future-ready health and safety procedures, policies, and regulatory standards that will keep hydrogen-fueled maritime activities as safe as possible.

EMEC’s role:

EMEC Hydrogen is the lead partner of the HIMET consortium and will support the the on-vessel testing and demonstration of a standalone hydrogen system for auxiliary power for the MV Shapinsay, which consists of containerised hydrogen storage and a hydrogen fuel cell.
