Tokyo Gas begins synthetic methane trial using green hydrogen
It’s an interesting solution mostly because it tames hydrogens’ nasty properties. H2 is highly corrosive – CH4 is not. H2 is way more flammable than CH4 and will explode in a wide range of air mixtures. H2 will transpire any material and hence always leak, no matter the containment – CH4 won’t. I am not even getting started with the unsolved economics of H” transport and storage and the complete lack of any serious infrastructure. So, taming H2 by adding some carbon is the way. But it needs to be green carbon and producing enough of that will be the challenge that dominates everything.
