RE: New Hydrogen Engine on the market30 Sep 2022 17:09
They are marketing it for heavy vechicles, I think. I've looked at this before and I found that for the same model of long-haul lorry in the US, electric has half the range of ahydrogen fuel cell truck . Of course, diesel is best of all. 1000 miles range is hard to beat! This new engine is still combustion, but it seems to work like a stirling engine, so it's very efficient. Also, I think that relying on big heavy hydrogen tanksnfor trucks is not the wtg, and it would probably be better to have a tank of liquid fuel (like Di-Methyl Ether) and smaller tank for hydrogen that gets produced from cracking the DME, perhaps with electrodes or better: microwaves (which can also crack water). This would mean that a battery would be required for producing the hydrogen on board the truck. I know this works against Igas's hydrogen production, but there's still going to be a market for it. For smaller vehicles, I'd say use hydrogen fuel cell and a battery for regen-braking. Choosing hydrogen fuel-cells for cars would be for the safety benefits (in a crash a leaking tank of hydrogen gas would shoot upwards instead of lingering around)and zero air-pollution (and I don't mean CO2 - nitrogen oxides, carbon particles, VOCs...).
