Hydrogen vs. Battery Electric Cars

Just wanted to mention that I’ve seen initiatives in Australia where they are making vehicle to grid and the idea is that if the car is plugged in during peak times it draws energy from the car battery to stabilise the grid. Then at night the car recharges. And people are actually getting paid for what they are “exporting.”
Aside from that Australia’s EV momentum is atrocious. Certain car companies won’t even bring them here because they can’t sell them.
