The "climate crisis" does exist, and the claim that life on earth wants more is false.
We are putting an enormous amount of carbon dioxide into the atmosphere.
I've started reading a book "The Hydrogen Revolution" by Marco Alvera, who has been involved with energy companies most of his working life.
He made the following startling comments - "To get an idea of how precious a resource oil is, consider that it takes nearly 25 tonnes of prehistoric buried plant material to make a litre of petrol (gas)." .... "Or, to put it another way, we are using up plants that would have required 40 acres of land every time we go visit grandma 20 miles away. These estimates are from Jeffrey S. Dukes, then an ecologist at Purdue University, who said; 'Every day people use the fossil fuel equivalent of all the plant material that grows on land and the oceans over the course of a whole year'".
If we think we can just go heedlessly adding more and more CO2 to the atmosphere, we're kidding ourselves.
The reason that hydrogen has been so slow to be developed as a fuel is that it takes a lot of energy to divide it from it's host compound, usually water, since it is rarely found by itself on earth. The hydrogen molecules in the atmosphere are so light and move so fast they eventually reach escape velocity in the upper atmosphere. So it rarely exists in free form on earth.
But there is plenty of hydrogen in water, and after burning via a hydrogen fuel stack, it goes back to water.
It has to be extracted first, and then compressed to very high pressure to make it practically useful. But with solar power becoming more and more accessible, hydrogen, in my opinion, will be the fuel of the future, for transport at least.
