GW Factory

The project aims to scale the Hystar patented electrolyser stack up to gigawatt production levels at a new automated production factory in Høvik, Norway. With an initial production capacity of 1.5 GW, the project plans to expand to 4.5 GW in phases. The project is expected to achieve 100% reduction in the relative greenhouse gas (GHG) emissions compared to the reference scenario.

The plant will manufacture PEM electrolyser stack technology (developed by Hystar), providing higher efficiency and safety profiles and reducing critical raw material needs compared to conventional technologies. The stack is designed to enable high-volume manufacturing capacities and will be produced on an innovative production line that prioritises sustainability and a human-centred design. Upon starting operations in 2027, the Project Sagitta is expected to generate 6 million metric tonnes of green hydrogen by 2036, which is comparable to the current annual hydrogen demand in Germany, the Netherland, Poland, Spain, Italy, the United Kingdom and France combined. During its first ten years if operation, the project will achieve approximately 11.3 million metric tonnes of GHG absolute emissions avoidance. 

Increasing the production capacity of electrolyser stacks will support the creation of a comprehensive and sustainable value chain for electrolyser components in Europe, contributing to job creation in the region. The Norwegian facility under Project Sagitta is projected to create approximately 400 direct jobs, with an additional 1000 jobs anticipated within the broader electrolyser proudction value chain. The project has a strong scale-up potential to be deployed across Europe.
