This competition is part of a suite of interventions to be launched by the UK Shipping Office for Reducing Emissions (UK SHORE). UK SHORE aims to transform the UK into a global leader in the design and manufacturing of clean maritime technology.

The Clean Maritime Demonstration Round 2 competition has two strands:

For strand 1, your project must:

  • have total costs between £100,000 and £1 million
  • end by 31 August 2023
  • carry out all of its project work in the UK
  • carry out the majority of the work in the UK for green corridor projects
  • intend to exploit the results from or in the UK

To lead a project your organisation must:

  • be a UK registered business of any size
  • collaborate with other UK registered organisations

Strand 1 of the competition is funding detailed feasibility studies and plans for innovative technology demonstrations of scalable clean maritime solutions. Your project must undertake a technical and economic feasibility study associated with the development and real world demonstration of one or more of the specific themes. You must plan for the real world demonstration being developed in your project to be operational by March 2025.

Your projects must:

  • underpin a future demonstration by delivering a meaningful technology, route to market, or supply chain innovation
  • achieve market potential through a clear strategy for commercialising the technology and the products, demonstrating the potential for significant value to the UK.
  • deliver emissions reduction by demonstrating a significant greenhouse gas reduction.
  • bring together a team with the necessary expertise and experience to successfully deliver the project according to its objectives, for example by including a representative end user such as vessel operators, ports or harbour authorities.

Technologies for all sizes and categories of maritime vessel, including pleasure and commercial vessels, are in scope. Solutions can be suitable for one target size of vessel or multiple. Where a project intends to utilise a vessel, the vessel should be a United Kingdom Ship, as defined in 85(2) of the Merchant Shipping Act 1995, or you must provide justification for use of a non-United Kingdom Ship in your application.

All ports and harbours are in scope, including infrastructure for both freight, pleasure and commercial vessels.

We strongly encourage projects from around the UK to support boosting jobs and economic growth, including from ports, vessel operators, vessel manufacturers and their supply chain. We welcome projects from areas with existing clean maritime expertise or co-located in clusters of renewable energy production and usage including hydrogen.

If your proposal focusses on a green shipping corridor, you must assess and develop a clear implementation plan for the real-world establishment of the corridor. To qualify as a corridor, plan for at least one zero-emission vessel to be transiting the route.

Your project can focus on one or more of the following technology themes:

Prioritised technology themes:

  • pilot fuel free hydrogen internal combustion engine technologies for maritime applications.
  • whole-ship energy efficiency design and integration
  • safe on-board storage of hydrogen and ammonia
  • larger (2.5 Mega Watt plus) marinised fuel cell systems
  • small craft alternative for fuel bunkering and charging
  • green shipping corridors both domestically and between the UK and other states including short and deep sea routes

Other technologies

Vessel low and zero emission technologies:

  • vessel propulsion and auxiliary engines, for example, battery, fuel cell, and internal combustion engines using low or zero carbon alternative fuels such as hydrogen, methanol or ammonia, and including hybrids and engines capable of using multiple fuels including zero emission options.
  • wind propulsion, including soft-sail, fixed-sail, rotor, kite and turbine technologies, targeting a range of ship types from small vessels to large cargo carriers, both as primary and auxiliary propulsion.
  • low carbon energy storage and management
  • physical connections to shoreside power or alternative fuels, including fuelling lines
  • enabling technologies such as motors, drives, sensors, and power electronics

Port and shoreside, including offshore solutions:

  • shoreside low and zero carbon fuelling including bunkering of such fuels
  • charging infrastructure and management
  • low and zero emission shoreside power solutions, such as enabling docked vessels to turn off their conventional power supply for ancillary systems
  • physical connections to shoreside power or alternative fuels, including fuelling lines
  • shoreside renewable energy generation at the port to supply vessels
  • zero emission shoreside power supply for vessels, including grid or renewable energy supply
  • low carbon fuel production, such as hydrogen, methanol, ammonia
  • zero emission infrastructure, including stationary assets for freight handling and port operations
