EU OYSTER Consortium Chooses Grimsby for Innovative Hydrogen Project

Grimsby has been chosen as the location for an innovative "marinized" electrolyser project for renewable hydrogen production.

The Fuel Cells and Hydrogen Joint Undertaking (FCH JU) funded OYSTER project will develop and demonstrate an electrolyser system designed to be integrated with offshore wind turbines. The project will also investigate the potential of using pipelines to transport hydrogen to shore.

Renewable hydrogen is rapidly emerging as a key tool in the green transformation, providing a clear green path forward for many sectors that would otherwise be difficult to decarbonize, such as heavy industry and heavy transport. Developing offshore hydrogen production, by utilizing electrolysers which only require water and renewable electricity to generate renewable hydrogen, further increase this potential by providing a means of transporting low-cost renewable energy from areas of excellent resource to demand centers.

Reaching the EU Hydrogen Strategy target of 40GW of electrolysers by 2030 is expected to require both onshore and offshore electrolysers. The OYSTER project - being undertaken by a consortium of ITM Power, Ørsted, Siemens Gamesa Renewable Energy, and Element Energy - will develop and test a megawatt-scale, fully marinized electrolyser in a shoreside pilot trial, which will be located in Grimsby. The project will also explore the feasibility and potential of combining an offshore wind turbine directly with an electrolyser and transporting renewable hydrogen to shore. The project is 100% funded by the FCH JU, a public private partnership of the European Commission, who awarded the project EUR 5 million in January 2021.

The OYSTER consortium selected Grimsby because of the region's strong connection to renewable energy, in particular offshore wind. Grimsby is home to the O&M hub for Ørsted's UK East Coast operations, including Hornsea One and Hornsea Two, which will be the world's largest offshore wind farm when completed in 2022. Both offshore wind farms use Siemens Gamesa turbines and are fitted with blades manufactured in Hull. The Humber is also home to Gigastack which is developing a blueprint for the deployment of industrial-scale renewable hydrogen from offshore wind. The Gigastack project is led by a separate consortium, consisting of ITM Power, Ørsted, Element Energy and Phillips 66 Limited.

Due to the high density of energy intensive industries such as refineries, power stations, steel works and glassworks that flank the banks of the Humber, the region is the UK's largest industrial cluster by carbon dioxide emissions; 12.4MtCo2/yr. Decarbonizations of the Humber is vital for the UK's legally binding net-zero 2050 target as well as the future economy of the Humber, and renewable hydrogen coupled with offshore wind could play a central role in achieving this ambition.

To realize the potential of offshore hydrogen production, there is a need for compact electrolysis systems that can withstand harsh offshore environments and have minimal maintenance requirements while still meeting cost and performance targets that will allow production of low-cost hydrogen. The OYSTER project will provide a major advance towards this aim.

The OYSTER electrolyser system will be designed to be compact, to allow it to be integrated with a single offshore wind turbine, and to follow the turbine's production profile. Furthermore, the electrolyser system will integrate desalination and water treatment processes, making it possible to use seawater as a feedstock for the electrolysis process.

ITM Power is responsible for the development of the electrolyser system and the electrolyser trials, while Ørsted will lead the offshore deployment analysis, the feasibility study of future physical offshore electrolyser deployments, and support ITM Power in the design of the electrolyser system for marinization and testing. Siemens Gamesa Renewable Energy and Element Energy are providing technical and project management expertise.

Dr Graham Cooley, CEO of ITM Power, said: "Renewable hydrogen is the cleanest fuel available to us today. Utilizing offshore wind energy, and generating renewable hydrogen using water in the process of electrolysis, offers a route to be able to decarbonize the entire energy system. ITM Power is delighted to be supporting this move towards a greener, cleaner future."

Duncan Clark, Head of UK Region for Ørsted, said: "The combination of offshore wind and renewable hydrogen production holds game-changing potential to decarbonize otherwise hard to abate sectors, and as the largest offshore wind company in the world, we are exploring offshore hydrogen production as a future, supplemental way of getting large amounts of renewable energy, generated from plentiful offshore wind, to where it is needed. Just as with scaling-up offshore wind, early lessons from projects like this can then be deployed across the region and around the world."

Michael Dolman, Partner at Element Energy, said: "Since supporting the formation of the OYSTER project, we've seen a growing number of projects planning offshore hydrogen production and increasing interest in this area from a wide range of stakeholders. With the selection of a location for the demonstrator, OYSTER is progressing well and will play a valuable role in advancing electrolysis technology for offshore applications."

Bart Biebuyck, Executive Director, Fuel Cells and Hydrogen Joint Undertaking (FCH JU), said: "In order to meet the challenging EU Hydrogen Strategy target of 40GW renewables-fed electrolysers by 2030, off-shore wind parks will play an essential role. Depending on local conditions it may be optimal to move the electrolysers offshore and transport hydrogen rather than electricity to shore. The FCH JU is proud to support the OYSTER project as a stepping stone for off-shore electrolysers through the development of a fully "marinized" MW-scale electrolyser to be tested right next to the sea front and therefore contribute continuously to developing technologies for a climate-neutral future."

About the OYSTER project and the FCH2-JU

This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (FCH2-JU) under grant agreement No. 101006751. This Joint Undertaking receives support from the European Union's Horizon 2020 research and innovation program, Hydrogen Europe, and Hydrogen Europe Research. The FCH2-JU is a unique public-private partnership supporting research, technological development, and demonstration (RTD) activities in fuel cell and hydrogen energy technologies in Europe. Its aim is to accelerate the market introduction of these technologies, realizing their potential as an instrument in achieving a carbon-clean energy system.
