Liquid hydrogen-powered autonomous ship project wins UK government funding


A consortium led by zero-emission vessel provider ACUA Ocean in partnership with zero-emission infrastructure provider Unitrove has won a multi-million-pound UK government grant in a major push to decarbonise the maritime sector.

The “Hydrogen Innovation – Future Infrastructure & Vessel Evaluation and Demonstration (HI-FIVED)” consortium will receive over £3.8m of funding to build and showcase its innovative autonomous vessel and bunkering infrastructure technologies for liquid hydrogen.

The £5.4m project is expected to be delivered in autumn of 2024 and aims to establish a domestic green shipping corridor between Aberdeen and the Orkney and Shetland Islands, with hydrogen-powered autonomous ships being used to transport cargo.

The HI-FIVED consortium involves several key players in the maritime industry including the Port of Aberdeen, the University of Southampton, Zero Emissions Maritime Technology, Composite Manufacturing and Design, Trident Marine Electrical, and NASH Maritime.
Unitrove, creator of the world’s first liquid hydrogen bunkering facility, will look to deploy its mobile fuelling technology at the Port of Aberdeen in support of ACUA Ocean’s bid to build and operate the world’s first maritime autonomous surface ship powered by liquid hydrogen.

The project is part of the Clean Maritime Demonstration Competition Round 3 (CMDC3), which was announced in September 2022, funded by the Department for Transport and delivered in partnership with Innovate UK. As part of the CMDC3, the Department allocated £60m to 19 flagship projects supported by 92 UK organisations to deliver real world demonstration R&D projects in clean maritime solutions. Projects will take place in multiple locations around the UK from as far north as the Shetland Isles and as far south as Cornwall.

The CMDC3 is part of the UK Shipping Office for Reducing Emissions’ (UK SHORE) flagship multi-year CMDC programme. In March 2022, the Department announced the biggest government investment ever in our UK commercial maritime sector, allocating £206m to UK SHORE, a new division within the Department for Transport focused on decarbonising the maritime sector. UK SHORE is delivering a suite of interventions throughout 2022–2025 aimed at accelerating the design, manufacture and operation of UK-made clean maritime technologies and unlocking an industry-led transition to Net Zero.

Michael Tinmouth, COO of ACUA Ocean, said: “Delivering successful technology demonstrations is critical to de-risking future investment in maritime decarbonisation. This CMDC3 project brings together a consortium of innovative partners, subcontractors, and suppliers from across the maritime sector, who are all laser-focused on the need to reduce emissions and accelerate the adoption and commercialisation of new technologies.”

Steven Lua, CEO of Unitrove, said: “We are absolutely thrilled to receive UK government support to enable real-world demonstration of the world’s first liquid hydrogen autonomous vessel and infrastructure. Having built such a strong consortium of eight fantastic partners across the supply-chain, we can have great confidence that we will deliver something truly remarkable.”

Marlene Mitchell, Commercial Manager of Port of Aberdeen, said: “We are delighted to be part of this transformational project, which is wholly in alignment with our green ambitions and that of the wider project team. Zero-emission fuels and vessels are an essential element in achieving decarbonisation within the maritime sector and green shipping corridors will play a key element in meeting the sector’s goals.
“This project offers a unique opportunity for our newly operational South Harbour to act as a practical and at-scale living lab for net zero in the port and maritime sector and will directly address the theme of zero-emission infrastructure and will also consider feasibility to develop shoreside renewable energy generation at our port to supply vessels in alignment with DfT’s 2019 Clean Maritime Plan.”

Madadh MacLaine, CEO of Zero Emissions Maritime Technology, said: “We can do this, and we will with the support of DfT and Innovate UK. The UK government is pushing the boat out on zero-emission shipping, supporting UK innovators who are committed to tackling climate change full-on. The partners in our consortium are making no compromises. Yes, we are facing an existential crisis, but the problem can be solved, and we’re here to solve it.”

ACUA Ocean and Unitrove have previously been successful in bidding for money from CMDC2 to explore the development of an innovative Zero-Emission Multi-Fuel Station (ZEMFS) that would power hydrogen and electric ships.
