Green hydrogen is one of the most important keys to shifting the transport sector’s dependence on fossil fuels to the use of renewable energy.
The global production capacity of electrolysis plants used to produce hydrogen is low, but will expand as demand for hydrogen and green fuels increases.
However, the high demand also requires the development of unified PtX and electrolysis technologies for hydrogen production that are scalable and cost-effective, as well as a significant amount of renewable energy to power the PtX plants.
The goal of the innovation project GreenHyScale is a 100 MW electrolysis plant built in GreenLab in Denmark, which can be copied in the rest of the world. The project aims to accelerate pressurized alkaline electrolysis to enable large-scale production of green hydrogen – which will make the establishment of a commercially viable hydrogen infrastructure possible. It is a cornerstone of the global green transition.
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 to confirm the solution for the future 100 MW project. Green Hydrogen Systems is the market leader in pressurized alkaline electrolysis, the most cost-effective type of electrolysis and a technology that works efficiently with the variable load from renewable electricity sources. As one of the world leaders in the manufacture and implementation of wind turbine generators, Siemens Gamesa will assume an advisory role.
The French company Lhyfe will provide optimized control systems for the 6MW units and is responsible for the long-term operation of the entire 100MW plant and integration to GreenLabs SymbiosisNet – an intelligent network of energy and data that allows companies in GreenLab’s green industrial park to share their excess energy with each other.
Once the prototype is complete and meets certain performance criteria, Lhyfe and GreenLab will also 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 electrolysis technology will then be developed into a 7.5 MW plant for use in an offshore environment.
Researchers from DTU and Imperial College and experiences from Eqinor and Everfuel will contribute to the project with several advisory aspects throughout the project period, ranging from technology design, assessment of the role and value of the GreenHyScale concept and providing recommendations for the transition to the CO2-free energy of the future. Energy Cluster Denmark is in charge of the communication of the project, and parts of the value chain and ‘replicability’ part, while Euroquality and Greenlab are in charge of project management.
