for energy
Re-electrification (long-term storage)
Chemical feedstock 
Carbon-neutral fuels in mobility and heat 
applications
Re-electrification (long-term storage)
Methanol as energy carrier for hydrogen
Chemical feedstock (e.g. power to steel)
Re-electrification (long-term storage)
Direct use in mobility applications (fuel 
cells)
Power-to-fuels (SNG, Methanol, GTL)
Power-to-hydrogen
Power-to-ammonia

Water electrolysis market ramp-up and industrial scale plant sizes will lead to significant cost reduction 
•
Small scale projects, R&D context
•
Hydrogen expensive due to high specific costs
•
Little development of scaled technology and 
supply chains
•
No commercial hydrogen offtake  
Small scale pilots so far
Industry scale solutions commencing now
• Refineries and ammonia plants request 
large volumes 
• Scaling reduces hydrogen costs 
below benchmark of 2 €/kg: 
supply chains, highly efficient 
equipment, efficient project development
