26 October 2021 marks the official kick-off of the GreenHyScale project whose purpose is to explore largescale production of green hydrogen. The goal is a 100MW electrolysis plant erected in GreenLab, Denmark, and replicable in the rest of the world.

GreenHyScale aims at accelerating pressurised alkaline electrolysis to enable large-scale production of green hydrogen – which will make the establishment of a commercially viable hydrogen infrastructure possible. This is a cornerstone in the global green transition.

Anders Bøje Larsen is the CTO at GreenLab, and he explains why large-scale production is so important when it comes to green hydrogen. “GreenHyScale is a very exciting project that allows us to work with large-scale production of green hydrogen – large-scale production is what will reduce production and distribution costs in the end. Our focus is to create a replicable solution for stakeholders in both Denmark and the rest of Europe – replicability is key to the dissemination of green hydrogen. That makes GreenHyScale an important project with the potential to contribute greatly to the positive development of a hydrogen infrastructure in and outside of the EU”.

“Being part of this pioneering project will enable Green Hydrogen Systems to demonstrate our unique pressurized alkaline electrolysis technology designed and optimized for use in large-scale green hydrogen production from renewable electricity. We are excited and honored to be part of an innovation project that not only affects the Danish energy transition but can accelerate Europe’s path to carbon neutrality by 2050. We strongly believe that the results of this project will have an immense impact on achieving the necessary scale for technological advancement and will contribute to lowering the levelled cost of hydrogen towards cost parity with fossil fuels”, says Sebastian Koks Andreassen, CEO, Green Hydrogen Systems.

“We are pleased to be a part of the exciting and ambitious GreenHyScale project. We see it as an important step in making green hydrogen commercially available, which is needed to assist the European energy transition. We are proud to work with strong partners who are all dedicated to developing the infrastructure for green hydrogen in Europe”, says Jacob Krogsgaard, CEO, Everfuel.

“It is good news for the green transition in Europe that the project has begun. If we are to meet the ambitions targets of CO2-reductions and green goals of Europe, we need projects like GreenHyScale – and we need to join forces across Europe. The partnership is a good example of what we can achieve when key companies from the European energy sector join forces in upscaling green electrolysis technologies,” says Glenda Napier, CEO, Energy Cluster Denmark.

From prototype to commercial scale

Backed by a solid 30 million Euro funding from the EU, each member of the GreenHyScale consortium is an important part of the puzzle: The Danish cleantech company Green Hydrogen Systems is responsible for delivering the first 6MW test module which aims at confirming the solution for the future 100 MW project. Green Hydrogen Systems is market leader within pressurized alkaline electrolysis, the most cost-efficient type of electrolysis, and a technology that efficiently works with the variable load from renewable electricity sources. As a world leader in the manufacturing and deployment of wind turbine generators, Siemens Gamesa will take an advisory role.

The French company Lhyfe will supply control systems for the 100MW plant and are responsible for the integration to GreenLab’s SymbiosisNet – an intelligent network of energy and data that enables companies in GreenLab’s green industrial park to share their excess energy with each other.

Once the prototype is done and meets certain performance criteria, Everfuel will oversee the task of scaling the project commercially, which will result in the completion of the 100MW plant based on Green Hydrogen Systems’ electrolysis. The 6MW high-pressure alkaline electrolyzer technology will then be evaluated for use in an offshore environment.

Researchers from DTU and Imperial College will contribute to the project from multiple aspects along the full project period, ranging from technology design, assessing the role and value of the GreenHyScale concept and providing corresponding policy recommendations for the transition to low carbon energy future. Energy Cluster Denmark leads the project’s advisory board and the external communication, while Euroquality leads the project management.
