@takvera Other studies disagree. The problem is that there is no way of directly powering heavy trucks with renewable energy. That is because they cannot just sit there and wait for the sun or wind. It will have to be fast charging. This puts enormous limits on what kind of emission reductions that are possible. It is very likely that FCEVs will be much greener in practice.
The only sustainable way is green hydrogen, and the need for that in other areas is so great there won't be any molrculrs left for trucks or the stupidity that are e-fuels.
@lil_meow_meow Agree. Green hydrogen will be needed fordecarbonising fertiliser production, petrochemical processes, shipping, perhaps industrial processes like green steel. Maybe some long term storage for grid balancing. Long haul trucking comes around middle of priorities. If you factor in building a hydrogen transport and refuelling infrastructure it adds cost and safety risk. See Liereich's Hydrogen Ladder version 5

Yes, Long Haul aviation is very problematic. Short haul low to medium passenger number aviation may be met by battery electric... or take high speed train.
I remember one of the European airline execs (could have been the Lufthansa guy, not sure) saying to the automotive and heating industry something to the effect of:
"Don't even think that you could run your products with green hydrogen because we, the aviation industry, will buy everything that'll be produced."
@lil_meow_meow@takvera He’s trapped in the fossil fuel mentality. There is basically infinite hydrogen available for transportation and industry purposes. It will never run out, and will can always scale up production to meet demand. It is all of the other ideas that will run out of supplies first.
@lil_meow_meow Your argument is just a logical fallacy. For starters, you can scale up exponentially. It is not hard to get to arbitrarily high production levels.
And saying we need to solve it in 15 years is just absurd, doomsday cultist thinking. Not to mention there is no such solution that works in that timeframe.
@lil_meow_meow You have your own issues then. Anyone who goes around saying climate change needs to be solved in 7-15 years is a doomsday cultist. You have about as deep of a grasp of the science of climate change as a climate change denier.
@lil_meow_meow@Hypx
scaling up #renewables capacity for green #hydrogen production is definitely a bottleneck.
Ahead of transport are addressing priority areas presently using Fossil based hydrogen with limited or no alternative options.
Useful to read IEA Renewables 2023 report (11 Jan 2024) on Renewable capacity for hydrogen. See pp 88-93.
@takvera@lil_meow_meow Everything is a bottleneck on some degree. But this is the most easily solved bottleneck. The other ideas will run into nearly insurmountable challenges if you try to avoid hydrogen altogether.
