Of course it could. In fact, that’s precisely what we’ve been hearing since the early 1970s.
The problem is that we’re further from achieving this than we were half a century ago. That’s because, in the interim:
• Battery technology has made great progress in terms of cost and both energy and power density.
• The hydrogen delivery infrastructure has gone essentially nowhere., while the transmission and distribution of electricity in general, and EV charging stations in particular continues to widen.
• The modes of hydrogen generation (electrolysis and methane reformation) remain grossly inefficient.
• Fuel cells that convert hydrogen into electrical energy are expensive and fragile.
Obviously, there are con artists (see above) who prey on those who don’t understand this.
