It's here.
Pilot project going on now.
I was on a very interesting webinar a couple of months ago via gas safe I think.
Pioneering hydrogen project takes first step in South Bank | Northern Gas Networks
South Bank in Redcar and Cleveland could become the base for the next phase of a pioneering hydrogen energy project aimed at reducing carbon emissions, as

Due to electrical resistance you can't shovel as much energy into a home down a wire as down a pipe.
@aurora123 - what did the guys at electrician forum say??????
Can someone tell me where all this hydrogen is going to come from, once all natural gas is replaced by hydrogen?
It's not as if this gas is waiting to be pumped out of the ground. It needs to be produced using electricity and there isn't going to be enough for this + electric vehicles.

You make a good point. Have a look round, it's called green hydrogen and more recently turquoise hydrogen. I am not saying it will become a practicality but a lot is being spent on the research.
I've heard of grey and blue, grey being H2 manufactured from CH4 using steam reformation. In all cases, electricity is needed.
I forgot to mention the additional electricity needed to power all the heat pumps that are supposed to be installed. Not a lot per heat pump but a lot of heat pumps.
I think gas is here to stay for many many years to come.

The designation brown, grey, green, turquoise are all due to their method of production. I am a simple observer not an advocate. It seems to me that there's plenty of hydrogen around and a lot of money being spent getting the hydrogen to the right place. Gas is here to stay, what that gas is, may change, hydrogen blend is being looked at, hard.
I was reading about colours of hydrogen in the "Corriere della Sera" the other day. It's all colourless, so these are technical terms only:
Grey - extracted from methane (CH4) without carbon capture and storage/sequestration (CCS) - releases lots of CO2.
Brown - extracted from coal without CCS - releases more CO2.
Blue - extracted from fossil fuels, but with CCS - CO2 captured.
Green - extracted from water using renewable energy.
Violet (purple) - extracted from water using nuclear energy.

I'm not an expert. All I did was summarise [EDIT - and translate from the original Italian] what was written in a newspaper article. Bit more effort than cutting and pasting to be honest. Glad you found it interesting though.
