- jhp123 4y agoAmount in the crust is hardly relevant. After all there are trillions of tons of lithium etc. in the Earth's crust. Transition to a "hydrogen economy" would put unprecedented demand on existing sources. It's not realistic.
- _hypx 4y agoHydrogen is also one of the most common elements in the Earth's crust. Hence why it will never run out. It is very relevant.
