Just came across this

very interesting... but no details how it works or overall efficiency...

Dear Dave,
Interesting, but if you've converted electricity to hydrogen why use more to make methane? Also I was intrigued to find they believed methane was neutral in climate change, I thought it was more of a greenhouse gas than CO2. Both gases are flammable and therefore are potential energy but methane can be produced from organic matter (eg. farm waste and sewage). Why not just store the hydrogen and use that? Thanks for the link anyway.
Love and Peace
Jim

Yeah I read methane is even more dangerous than CO2 as a greenhouse gas. Claimed also to be one of the main component for the end of the last ice age.

yes - methane has around 22.5 times the greenhouse effect of CO2 so not sure what is going on there... I think the point is that storing and transporting hydrogen is a lot more difficult than natural gas, for which we already have an infrastructure.. and mainland Europe has oodles of gas storage ready to use. UK doesn't.
