Hydrogen is a very difficult fuel to handle. Leaks can easily cause explosions and then there is the problem of hydrogen embrittlement of steel.
I have convinced myself that “renewable energy” is burning wood.
The rest is just Government making changes so that you have less, in the end. It is making these “green” energies cost-competitive by raising the price of existing alternatives.
No one knows how much CO2 the Earth’s atmosphere is “supposed” to have. Those who say differently are selling snake oil.
Where did you ever get that idea? Oh, wait.

Oh the other hand, this is a core belief of every liberal:
“This time it will be different.”
Here is a hydrogen explosion video paid by taxpayers.
Project of senator Kelly.

Agree. But I repeat my experience with H2 slush from the X-30 research plane in 1988-1995: We produced it, burned it, stored it, transported it, pumped it.
It was one of the most successful elements of the program. It was slush in order to cool the incredibly hot leading edges of the airplane.
I think a devoted effort by the PRIVATE SECTOR could yield usable H2 in about 50 years.
