I am very positive on the future of renewables (solar PV, wind). These will completely crush fossil fuels even more than they already are. I am glad that this is happening.

I am pretty pessimistic about the prospects of hydrogen in general, so I can't provide any suggestions, sorry. Green hydrogen is just a mechanism to move renewable energy from one place to another. My scepticism is mainly from the high capital costs to make hydrogen at scale and transport it, and inherent energy losses along the way at each stage of conversion. Why not just build the renewables where the energy is needed rather than bothering with all the hydrogen stuff and energy losses?
