Gas is banned

Article on BBC site about blending hydrogen with natural gas and reducing carbon emissions from domestic heating

We always used to have a blend of hydrogen, carbon monoxide and nitrogen before 1967

Gas made from coal, before my time.

 

The BBC article says 1/3 of our carbon emissions come from domestic heating with gas.

Yeah coal gas - made by burning coal without oxygen - similar to charcoal making.  Terrible for the environment and the gas itself was poisonous.  This new development is not to do with coal gas - but it sounds a little pointless to me.  They are saying they could use up to 20% hydrogen.  Maybe it would be better to use the money to subsidise good quality house insulation.  And I don't mean the awful debacle of government sponsored cavity wall insulation, but properly specified and installed insulation.  It is a minefield though, I will admit.

Yes the article does state this, but of course this was written by a journalist and I am pretty certain this is nonsense!  Not easy to prove without spending the afternoon trawling the web though, so maybe someone more in the know can shed some light on this?

Not a million miles away by the looks of it.

 

Image below from government figures and quick google suggests 85% of heating is provided by gas

Thought GSHP only good for modern well insulated homes and with underfloor heating otherwise large lecky bill.

Well insulated yes but age does not matter. Our GSHP is in a 200 year old barn with IWI.

Dont get me wrong I do like heat pumps, really good for underfloor heating BUT no good for hot water and expensive install. 

 

 

 

 

Expensive to instal well yes relatively but ours wasn't anything like the figures you hear banded around these days. When we first had our GSHP I worked out in the summer we were using 2.38 kWh a day for hot water. At 15P per kWh thats just 35p a day

Yes, until we find the hydrogen mines, the hydrogen economy seems a misnomer.

I would of thought the idea with Hydrogen is when we have an excess of renewable energy (which has happened a few times lately and will only happen more) the excess can be used to split hydrogen from water. Why not use what is basically free energy

Slightly off topic, but I was on a stag do recently. One of the guys was an engine engineer boffin, and another was high up in Enterprise car rentals. They were both convinced that Hydrogen should be the future for car propulsion rather than electricity. There are a couple of technical challenges to overcome first though.

 

Hydrogen is by far the most abundant element in the universe so you would think it had quite a lot going for it.
