Intregrated Hydrogen System for Tidal Energy Storage
ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to announce that it has won a competitive tender to supply an integrated hydrogen system for use at the European Marine Energy Centre (EMEC) tidal test site on Eday, Orkney, Scotland. The system’s principal component is a 0.5MW polymer electrolyte membrane (PEM) electrolyser with integrated compression and up to 500 kg of storage. We have also offered an additional maintenance contract alongside the integrated system as well as a fuel cell for local back up power. The total contracted value of the project is £1.79m.
Including this project, the Company currently has £9.97m of projects under contract and a further £5.79m of contracts in final stages of negotiation.
The 0.5MW electrolyser will be used to absorb excess power generated by the tidal turbines testing at EMEC. The hydrogen gas generated will be compressed and stored, with some of the gas being used in (an optional) hydrogen fuel cell to provide backup power to critical EMEC systems. The remainder of the hydrogen gas will be used off-site by a further project being developed separately which plans to absorb output of a local community wind turbine operated by Eday Renewable Energy Ltd.
Subject to contract ITM will supply, integrate, commission and maintain all parts of this system. The electrolyser will be packaged in a standard 20’ and 10’ ISO container and is summarised below:
• Hydrogen generation capacity up to 220kg/24hours
• Self-pressurisation up to 20 bar
• Rapid response
• Hydrogen purity satisfying ISO 14687
• CE compliant
Neil Kermode, Managing Director, EMEC, commented: “We are really excited about the deployment of ITM Power’s PEM electrolyser system on Eday. This is an innovative way to tackle the shortcomings of the local grid which is holding back marine energy in Orkney. It will allow us to not only pilot the production of hydrogen fuel from tidal energy, but will allow surplus renewable energy on the island to be used without having to rely upon the inadequate grid. We really see this as the moment we begin to break away from the shackles of a 20th century cable architecture.”
Dr Graham Cooley, CEO, ITM Power, commented: “We are delighted with this sale and to be working with EMEC on the Orkney Islands. ITM Power’s PEM Electrolysers are perfect for island deployment given the logistics of power distribution and fuel supply and this application by EMEC is a fantastic example as to how the rapid response functionality of ITM’s systems offer freedom from the grid constraints of distributed and remote renewable energy”
