Toyota's Hydrogen ICE is looking pretty good...
Like "pretty good" as in aesthetically?
Because as a fossil fuel replacement engine, it looks dead in the water. I just don't understand what people's fascination with hydrogen is. It's absolutely not going to replace fossil fuels. EVs are here, they work pretty well with our current infrastructure, and they're already cheap and reliable, and getting cheaper every year.
To replace petrol/gas & diesel with hydrogen, we'd have to replicate the ENTIRE chain of fuel creation and distribution. We can't just stick hydrogen in the same trucks, pipes, and tanks. We can't use the same pumps, seals, gaskets, sensors, anything! So from the refinery, storage there, pipes to distribution hubs, tanker trucks, gas station tanks, all the pumps, all the everything....it all needs to be replaced with hydrogen compatible stuff.
But in places where EV ownership is skyrocketing, the electric grids are largely holding up. The last mile seems pretty good. We do need to beef up some of our major interstate transmission lines, but that's driven more by the installation of renewables than the increase in EVs.
How are people thinking we're going to replace or duplicate our entire fuel network to support hydrogen more cheaply than we can just plug EVs into the existing power grid? I don't understand what makes anyone think hydrogen is going to be easier to switch to than electricity, which already exists at the gas stations we'd need to completely renovate to handle hydrogen. Let alone which already exists at home, where 95% of EV charging happens.
