Milford Haven: Energy KingdomMilford Haven: Energy Kingdom

Milford Haven: Energy Kingdom (MH:EK) is a £4.5 million project exploring the vital role hydrogen could play in a decarbonised energy future.

The project is primarily delivering a Front End Engineering Design (FEED) study that is laying the foundations for what could be the first of many Smart Local Energy Systems, and seeks to make a strong business case for investment in hydrogen to the Government and engaged key stakeholders in the Waterway.

Riversimple's hydrogen powered RASA car

The project will also demonstrate the practical application of hydrogen technology. Plans are still in development and subject to relevant permissions, but the aim is to demonstrate and test feasibility of two hydrogen powered RASA cars, built by Welsh company Riversimple, that should be operating as fleet cars in and around the Haven, with a green hydrogen electrolyser and refuelling facility to be built and located on the Port estate. A hydrogen-ready smart hybrid heating system is also being designed and will be installed and tested in an operational Port building.

MH:EK Objectives

  • Provide a roadmap to decarbonisation through the design of a hydrogen and renewables smart local energy system.
  • Stimulate growth and investment.
  • Increase education and upskilling possibilities for job creation and retention.


We are working alongside Pembrokeshire County Council, Wales & West Utilities, Riversimple, Offshore Renewable Energy Catapult, Arup and Energy Systems Catapult with collaboration and support from Community Energy Pembrokeshire, Western Power Distribution, RWE, Simply Blue Energy and the Welsh Government Energy Service.

Delivery Term

The project is due to be completed in Spring 2022.
