Comment on Toyota trials hydrogen-powered vehicle on public roads in Australia
SupraMario@lemmy.world 11 months agoThe issue with this metric is they’re talking about energy used to get the power. It completely ignores the fact that hydrogen can already be pulled from the atmosphere using solar plants. There are a few companies out there now that are developing stations that are basically automated.
The ICE motors Toyota and Hyundai have shown, have very little loss of HP/Tq numbers from their gas counter parts. Unless the battery industry comes up with a super light, quick charging (5 mins) and long lasting battery, EV will be resigned to the city at best and no heavy workloads for it either.

Efficiency still matters significantly with hydrogen solar panels, because solar panels aren’t free.
Suppose solar to wheel is 60% efficient in a battery electric vehicle, but 30% efficient in a hydrogen vehicle. You need half as many solar panels to power the battery electric vehicle, and spend at most half as much to charge it. That matters.

It really doesn’t when the hydrogen you’re burning isn’t creating pollution like the mining and destruction of the earth that lithium batteries create.
