Clean Maritime Demonstrator Competition


CATAGEN have been successful in a consortium application to the Clean Maritime Demonstrator Competition (CMDC), supported by UK Department for Transport and Innovate UK.

The Techno-economic Study of ClimaHtech Innovative Clean Maritime Solutions is part of the Clean Maritime Demonstration Competition Round 4 (CMDC4), funded by the UK Department for Transport (DfT) and delivered by Innovate UK. CMDC4 is part of the Department’s UK Shipping Office for Reducing Emissions (UK SHORE) programme, a £206m initiative focused on developing the technology necessary to decarbonise the UK domestic maritime sector.




The Consortium brings diverse partners including technology innovators, fuel distributors, maritime decarbonisation catalyst organisations, and harbour and government authorities. The project will be led by CATAGEN, partnering with The European Marine Energy Centre (EMEC), Orkney Islands CouncilHighland Fuels Limited, and Belfast Harbour.

The project consists of a techno-economic feasibility study exploring the opportunity of bringing novel clean fuel production technology to market, which has the potential to deliver significant decarbonisation to the UK’s maritime activities.


CATAGEN is developing a process for new liquid e-fuel production using its energy efficient patented E-FUEL GEN reactor. This is a new approach to create an energy dense hydrogen fuel carrier that uses renewable energy sources.

The techno-economic study aims to determine the commercial viability of using CATAGEN’s E-FUEL GEN technology to produce e-diesel and E-Fuels for the maritime sector in marine vessels and to supply port-side equipment.

The project’s core methodology involves harnessing a wealth of data, including local renewable energy generation potential, fuel demand profiles, fuel infrastructure, fuel storage and distribution insights provided by project partners. Through meticulous analysis, the consortium seeks to determine the efficacy of CATAGEN’s ClimaHtech technology in expediting the reduction of carbon emissions in maritime operations of Belfast and Orkney partner ports, establishing a replicable model for adoption across various harbours and ports in the UK.

  • Will bring valuable insights into the Orkney Maritime industry (hydrogen production currently in place), and support the development and data requirements for the study.


  • Will provide data of relevant area / harbour / operations / current and future requirements of
    the area.

  • Contribute and provide maritime decarbonisation expertise to some elements of the report. 


  • Will provide data acquisition, advisory and guidance in the Maritime industry, and provide feedback on the analysis and report.


  • Will also bring a local government and regulatory aspect to the project.

  • Will provide data and information on blending of fuel, storage and distribution infrastructure at Orkney to support development of use cases.


  • A wealth of experience on innovative product development, and distribution of fuels in Orkney 

“As the primary gateway to Northern Ireland, a key hub for trade and the 9th largest port in the UK, Belfast Harbour handles more than 70% of the region’s imported and exported goods transported by sea. At the heart of the city’s Innovation District, the 2,000-acre Harbour Estate is also home to over 760 businesses. Since 2019, the delivery of an ambitious five year, £254m investment programme has supported regional economic growth, and enabled the visible and celebrated transformation of Belfast Harbour.


While we are first and foremost a port, Belfast Harbour is increasingly recognised as a hub for thriving and innovative industries in Northern Ireland, including engineering, commercial and residential real estate, maritime technology, and the renewable energy sector.


As we continue to develop and build a Port for everyone, sustainability is at the centre of our business model, and we recognise that we can achieve more through collaboration and partnership. Innovative organisations such as CATAGEN, Artemis Technologies and Harland & Wolff (H&W) call Belfast Harbour home and with whom we’re working hard to progress our collective ambitions around decarbonisation” – Belfast Harbour
