Norman, £100s millions have been spent on the big Hydrogen lie, and continue to be spent.
H2 never was vaiable for domestic use, it's a scam generated by Gas Operators because without it they don't have a business.
The notion is crazy that 3x the amount of H2 is needed to produce the same amount of energy the Natural Gas does and that H2 is planned to be produced by burning Natural Gas.
And the Carbon from that is pumped offshore to be stored, more expense.
And it goes on. Some schemes are on their 3rd round of funding for the same proposals just badged up differently.
Scam.
