Gigastack will demonstrate that renewable hydrogen is essential to the UK’s 2050 net zero greenhouse gas emission target and the decarbonisation of large industrial clusters. Accelerating the uptake of renewable hydrogen through Gigastack is vital and will facilitate the development of a UK renewable hydrogen technology hub as well as the creation of a world-leading supply chain and highly skilled jobs across the sector.

What is Gigastack?

Gigastack brings together an ambitious consortium to prove economically viable renewable hydrogen at scale by:

  • Developing electrolyser technology to produce renewable hydrogen at large-scale
  • Coupling one of the largest offshore wind farms in the world with the largest carbon emitting industrial zone in the UK on a pathway to net zero
  • Decarbonising large industrial clusters through collaboration

Project timeline

There are three high-level phases to the Gigastack programme that will take the concept from the feasibility stage to the build and supply stage in the mid-2020s.
