The only thing wrong with Japan's economy is its leadership.

Norway threw socialist oil billions into developing #hydrogen vehicles for two decades, but it kept killing people so they stopped.

Toyota is butthurt they jumped the wrong way on EVs, but hydrogen is not the messiah they need.

(I drive a Toyota Camry hybrid as my daily. Toyota needs to stay with what works, and stop trying to impress SoftBank and friends).

As has been the case with battery technology, portable hydrogen technology will evolve. Here’s an example of relatively recent progress on using hydrogen released from the reaction between aluminum and water. The concept isn’t new, and the slow walk of it is an example of alternatives to electric/battery being sidelined as a carbon replacement.

Much better - no hydrogen stored, generated as needed. Mature technology too - replaced the Otto II fuel in NATO torpedoes in the '70s, I believe.

Energy density is low but acceptable for marine use where water is everywhere and free.

On land, forget it, even lead-acid has better power density than aluminium-water.

Aluminium-air, OTOH, has potential, but the technology is far from ready.
