Industrial scale renewable hydrogen project advances to next phase

GBP 7.5 million funding secured for phase two of Gigastack, which is to demonstrate low-cost, zero-carbon hydrogen in the UK to industrial scale. Project consortium includes ITM Power, Ørsted, Phillips 66 Limited and Element Energy.

GBP 7.5 million funding has been awarded for the next phase of Gigastack, a new renewable hydrogen project, as part of the Department for Business, Energy and Industrial Strategy (BEIS) Hydrogen Supply Competition.
The Gigastack project, led by ITM Power, Ørsted, Phillips 66 Limited and Element Energy, will show how renewable hydrogen derived from offshore wind can support the UK's 2050 net-zero greenhouse gas emission target.
Producing hydrogen has traditionally been associated with high carbon emissions, but by using renewable electricity, e.g. from an offshore wind farm, the process of producing hydrogen from water (electrolysis) can be completely decarbonised. Energy-intensive industries and the transportation sector will have the opportunity to reduce the carbon intensity of their fuels by using renewable hydrogen.
As part of the initial feasibility phase of the Gigastack project, which finished in 2019, ITM Power developed designs for a low-cost modular 5 megawatt (MW) electrolyser 'stack', collaborating with Ørsted to understand the potential synergies with offshore wind farms and with Element Energy to undertake a market analysis and explore business models for the first industrial-scale 100MW electrolysers.
For the second phase of the project, which has now received funding from the department for BEIS, the consortium will conduct a Front-End Engineering Design ('FEED') study on a 100MW electrolyser system using staged installations with a nominal capacity of 20MW.
The FEED study will detail the actual design of a hydrogen production system connected to a wind farm and industrial off-taker using ITM Power's new generation of electrolyser stack technology, renewable energy directly from Ørsted's Hornsea Two offshore wind farm, and with the resulting renewable hydrogen supplied to an industrial off-taker; Phillips 66 Limited's Humber Refinery. A key objective of the Gigastack project is to identify and highlight regulatory, commercial and technical challenges for real applications of industrial-scale renewable hydrogen systems.
As part of the second phase, ITM Power will also install and trial both their next-generation electrolyser stack and the semi-automated manufacturing machines required for large-scale and high-volume manufacture of these new large low-cost stacks. This will help validate a complete production system capable of delivering hundreds of megawatts of electrolysers per year.

Anders Christian Nordstrøm, Vice President for Hydrogen, Ørsted, said:

"Creating renewable hydrogen with offshore wind really has the potential to decarbonise industrial processes, and what is needed now is to scale up the electrolyser technology and bring the cost down. We've seen this happen in offshore wind. With industry and government working together, there has been a rapid deployment and a huge cost reduction. This project aims to do the same with hydrogen. At the right cost, this technology has the potential to play a huge role in meeting the UK's decarbonisation targets. We're excited to be part of this project in the Humber region where we are already very active, including constructing the biggest offshore wind farms in the world, Hornsea One and Two, and with them setting the global standard for deployment of offshore wind at scale."
Darren Cunningham, Lead Executive UK and General Manager Humber Refinery, Phillips 66 Limited said:

"Phillips 66 Limited is excited to be involved in the Gigastack project. This project aligns with our record of developing new low-carbon markets within the UK and worldwide, following our innovative technologies, which are key to lithium-ion battery production and, more recently, our biofuels produced from used cooking oil."
"The Humber region is uniquely positioned within the UK for the large-scale deployment of renewable hydrogen. Direct access to existing offshore wind power and a developed industrial base with hydrogen demand at Phillips 66 Limited's Humber Refinery provides an ideal opportunity to develop a new renewable hydrogen market where the feedstocks are just water and renewable power."
Dr Graham Cooley, CEO, ITM Power, said: 

"The second phase of Gigastack includes stack scale-up, volume manufacturing and a FEED study for a refinery deployment. The project will result in a scalable world-class product for the production of low-cost renewable hydrogen."

Project partners
Gigastack brings together:

  • ITM Power, a developer and provider of world-class hydrogen systems with 16 years of experience;
  • Ørsted, a renewable energy company with 25 years of experience in deploying and operating wind farms;
  • Phillips 66 Limited, the UK subsidiary of an international, diversified energy company and the owner of the Phillips 66 Humber Refinery, one of Europe's most complex refineries;
  • and Element Energy, a zero-carbon consultancy with 17 years of experience in hydrogen technology projects.

Details about the project

  • ITM Power will finalise manufacturing designs and test their new generation of electrolyser stack technology, which enables very large stacks (up to 5MW) thus reducing costs and improving efficiency. This will enable the future deployment of 100MW scale electrolyser systems.
  • ITM Power will install and trial the semi-automated manufacturing machines required for large scale and high-volume manufacture of these large low-cost stacks. ITM Power will remove bottlenecks and validate a complete production system capable of delivering hundreds of megawatts of electrolysers per year (initial target 300MW/year, ramping to 1GW/year).
  • Led by Ørsted, the consortium will conduct a FEED study on the application of a 100MW electrolyser system, using renewable energy directly from Hornsea Two offshore wind farm, and supplying the resulting renewable hydrogen to the Phillips 66 Humber Refinery, where it will reduce CO2 emissions from the refinery by lowering the consumption of fossil-based hydroge
  • The 100MW will be made up of 20MW electrolyser module systems, including all aspects of dynamics and integration of renewable hydrogen supply based on power from offshore wind.
  • The study will consider the market and regulatory conditions required for the installation of up to (and potentially beyond) a 100MW-scale electrolyser.
