What needs to happen now?The missing dots to make it THE BIG THING
• Real Political Commitment and ACTION:
• From Demo to Real Implementation at extended scale • + R&D and Technology development & optimization• Sometimes you need to enforce
• Serious supporting schemes to make our world better:
• Serious Favorable Drivers for a H2 Economy• Well setup tools and incentives to make a REAL decarbonization • Cost? Yes. But fair comparison with total socio-economic cost of fossil fuels
• Full Market Spectrum:
• Medium size (5-10-20MW) OR/AND Large scale (50 – 500MW) (Economies of scope)• Every geography / country / industry has its own business case (small, big)• Continue international “Standardization”
Number one by nature
