Reply to comment by deck_hand in Green Hydrogen - Not The Fuel Of The Future by Realistic-Plant3957

The study implies that refitting the pipelines to carry hydrogen gas is going to be much tougher than some have previously suggested.

Hydrogen atoms are minuscule even on the atomic scale, so they pass through metal like its a thick sponge. They happily become part of the metal structure and just wander around until they exit.

Turning the gas from hydrogen (H2) into methane (CH4) means you don’t need to change the lines to carry the gas.

And you’re back to using methane reformation but with more steps.

Extracted petro-methane is going to be cheaper always.

Or, and here me out, not breaking the methane back into hydrogen gas at the other end. Methane can be freely burned for heat and/or power, because it wasn’t sourced from fossil fuels.

Yep, 100% agree with you.

The problem has always been the “petro” in petrochemicals, making fuel from the atmospheric CO2 and venting it back to the atmosphere is a valid (and in my opinion excellent) solution to the current crisis.

Still requires legislation to avoid the “petro” sneaking back in and quite a lot of storage to remove the current excess CO2.

It’s a step forward, and that’s progress

Show me the legislation and I’ll agree with “forward” :-)
