UK SHORE and Innovate UK are delivering £77 million in match-funding to support high TRL research in close to commercial clean maritime technology. Funding will be made available to cover the construction and set-up of projects until March 2025, with project partners covering all costs of demonstrating in an operational environment until March 2028. This multi-year operating period will provide valuable data, demonstrating the efficacy of zero emission solutions in a real-world environment and across a range of operational states. The outputs of these projects will help to develop the wider clean maritime sector as well as inform future policy and regulatory decisions.

Innovate UK, part of UK Research and Innovation (UKRI), will invest up to £121 million from the Department for Transport in this competition. This is subject to a sufficient number of high quality applications being received.

This funding will be for projects to carry out deployment trials, pre-deployment trials and innovative feasibility studies, each of which forms a separate strand of this competition.

The Clean Maritime Demonstration Competition (CMDC) Round 7 is part of a suite of interventions launched by the UK Shipping Office for Reducing Emissions (UK SHORE) programme.

The UK SHORE programme aims to:

  • transform the UK into a global leader in the design and manufacturing of clean maritime technology
  • accelerate the fuels and technologies required to decarbonise the sector to meet net zero
    Your proposal must focus on clean maritime technology.

This competition is split into three strands:

The aim of the Deployment trials strand is to fund real world demonstrations of innovative clean maritime technologies in an operational setting. Your proposal must develop, test and deploy innovative clean maritime technologies for on-vessel or maritime infrastructure use, or both.

The aim of the Pre-deployment trials strand is to fund pre-deployment testing of innovative clean maritime technologies. Your proposal must design, develop and test, but not deploy innovative clean maritime technologies for on-vessel or maritime infrastructure use, or both.

The aim of the Feasibility strand is to fund feasibility studies of innovative clean maritime technologies and skills. Your project must undertake a primarily desk based technical and economic feasibility study. Your study must be associated with the development and future real world demonstration of innovative technologies for on-vessel use, maritime infrastructure use, skills or a combination of each.
