I will readily confess that 20 years ago I was not convinced that EV’s were the answer to sustainable energy. Instead, I had long been a fan of hydrogen. I was well aware that there were technical issues associated with hydrogen, but was equally aware that, for total sustainable energy, a transportable fuel is needed and hydrogen seemed to be the way to go.I envisioned hydrogen generation from sustainable sources (wind, solar, etc) and the use of hydrogen with fuel cells in cars, ships and with gas turbines in airplanes.
