The 'Hydrogen in an Integrated Maritime Energy Transition' (HIMET) project will demonstrate maritime decarbonisation enabling technologies, encompassing the design, development, and demonstration of four solutions:

1.Hydrogen systems and future micro-grid architectures for resilient shore-side power, including testing of a hybrid hydrogen/solar system and deployment of this hybrid system on Orkney;

2.Combustion of hydrogen in a marine propulsion engine, through testing at a dedicated hydrogen test facility in the north east of England;

3.Demonstration of a marinised hydrogen storage container, for the application on board a vessel; and

4. Hydrogen fuel cell demonstration, showing the potential of the technology to safely supply auxiliary power for a vessel.

This ambitious programme of activities will focus on the decarbonisation of two key maritime sectors in Orkney: ferry service and cruise terminal operations. These first-of-a-kind demonstrations will build the evidence base needed to enable broader maritime decarbonisation using hydrogen technologies. Although our activities focus on addressing challenges seen in the Orkney context, our findings will be applicable to all island and coastal environments where vessels provide vital lifeline services.

After project demonstration activities are complete, HIMET partners will pursue opportunities to develop applications for type approval of the systems demonstrated, in order to facilitate uptake across the UK, and beyond. This will create market opportunities for the integrated HIMET team of UK technology developers and maritime engineering experts.

In parallel, we will also carry out research and stakeholder engagement activities to establish how these deployments can best inform the broader maritime energy transition in Orkney and elsewhere. We will draw upon embedded energy system and maritime innovation expertise in Orkney and in the north east of England, both areas identified as centres of excellence in research and development for these sectors. Our consortium is further strengthened by the involvement of leading technology developers from all across the United Kingdom, who will bring their innovative systems and solutions to Orkney for testing in our "living laboratory".

This combined work programme will build on Orkney's position as an ideal location to research, develop and demonstrate the maritime technologies and working practices of the future.
