French nuclear giant scraps SMR plans due to soaring costs, will start over, page-197

Hydrogen can be piped but it's very difficult and it's very expensive.

APA may have been testing hydrogen blended with natural gas . lt certainly can't be pumped through natural gas pipework by itself .

Hydrogen embrittlement and leaks of the standard pipework would be a nightmare.

Hydrogen converted to ammonia is much easier but there are extra efficiency losses to consider.
