I’m a bit skeptical about hydrogen being a near term solution. A natural gas hybrid train can lead to significant reductions in CO2 emissions with technology that is known to work.
Erik, would you agree? Skeptic due to “source” of fuel. End result is fine but examine the very beginning of this fuel and it, well, becomes, in your words, “skeptical”. endmrw0306251534
My first concern with hydrogen is the very low energy density. Second concern is hydrogen embrittlement of various metals at high pressure.
Much skepticism on “green” ways of making hydrogen - easiest way is to make it from natural gas.
The only place you can get a hydrogen powered car is southern California. The fuel costs are so extreme that Toyota as a incentive gives you a 15k gift card for the fuel costs.
One of the few filling stations is along my normal commute to work, so it would be relatively convenient for me.
FWIW, I did get a ride in a hydrogen powered Rav4 10 1/2 years ago. The performance seemed pretty decent and also seemed to be a bit more practical than the electric IQ are company was using to get the SD commuters from the Irvine station to the office in Santa Ana - haven’t done that commute for 10 years.
