electrician vs gas engineering

[kasser]

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.

Turquoise hydrogen production has to do with methane, natural gas.

the wonders of cut and paste...makes everyone an instant expert LOL

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.

Maybe you're showing us up with your "corierre de la sella" - closest I get to that is the menu leaflet stuck on my dominos pizza box

I'm running a news agent's shop in Italy at present, so no great feat to have flicked through the odd paper. Not trying to show anyone up: I just like to state what my sources of information are, especially when I have no way of knowing whether they are correct or not.
