To be fair I've never seen mention of pure hydrogen as a replacement for nat gas but a mixture of hydrogen and ? which i guess lowers emissions and helps keep it in the pipes.
Let's hope its leaking under a certain government buildingMy uncle is a civil engineer for a one of the companies working on the gas network.
They have been slowly increasing the hydrogen in the mains for quite a while. Coal gas apparently had a very high hydrogen content.
They have been testing the pipework and he said the hydrogen is easier to seal than natural gas.
Although worryingly he also said that quite a bit of the London gas network is literally non existent. It is so old the pipes have completely rusted away and the gas just runs in the little clay tunnels that are left
have read that elsewhere too .... but they can not do it if you are not indebted to them, or have made efforts to recover said debt and only after informing you of their plans and why apparently.They don't have to cut your gas or electric off if you have a smart meter they can do it from there office what companies have been doing is send an email telling you they have put you on prepaid meter and we have increased your rate to help pay what you owe .So they have switched off you gas, electric if you have no money

You’re still talking about very old technology managing to keep it contained for days at a time, if not longer, Gra. In that time there’s been advances, 316 stainless is virtually impermeable at normal temperatures, there are ceramic coatings that reduce it to almost zero in carbon steel, Teflon seals are used in some pipe work.didn't say it pisses out Bri ... but it will permeate just about anything ... the molecules 'squeeze' through the gaps between the molecules of the containment materials.... the Zeppelins were a series of multiple cells, within cells (bit like bubblewrap) , which is why when you see footage of it going down in flames the flame front travels the length of it and doesn't just go off with one massive explosion
agreed on all counts ..... but the gas network is " very old technology " for the most partYou’re still talking about very old technology managing to keep it contained for days at a time, if not longer, Gra.

Also mixing hydrogen with natural gas doesn’t make a squat of difference to the hydrogen leaking out. It doesn’t bond to the natural gas and sits within the mix as a discrete molecule. it’s not impossible to seal hydrogen in a system, just harder, in the same way that what will seal a water pipe won’t seal some oils, or other fluids.

There’s still some cast iron gas pipes round here. They’d leak if you shoved coal through them.plastic pipe or cast ,leaks like a sieve
no ... just 6 times more CO2 than burning natural gas, in manufacturing the bloody stuff in the first place" If the Whitby proposal is approved, pure hydrogen will flow through its pipes from 2025. Hydrogen's advantage is that unlike natural gas, it doesn't produce the climate-warming gas CO2 when burnt. "

Hydrogen heating trial treats us like guinea pigs - residents
An English town could be the first to turn off fossil fuel gas, but some residents aren't happy.www.bbc.co.uk
you have now gaz
,s just tripped over this BobThey don't have to cut your gas or electric off if you have a smart meter they can do it from there office what companies have been doing is send an email telling you they have put you on prepaid meter and we have increased your rate to help pay what you owe .So they have switched off you gas, electric if you have no money

Energy firms remotely swap homes to prepay meters
The regulator said some "vulnerable customers had been left without power for days or even weeks".www.bbc.co.uk
" 'Disconnection by the backdoor'
Once a smart meter is installed, it is a much simpler process for a supplier to swap the customer into prepay mode at the push of a button, rather than having to apply for a warrant and install a physical box.
Ofgem's rules state that energy companies must speak to customers before moving them on to a prepayment meter, but the regulator said it was concerned this was not always happening.
Suppliers may put customers on prepayment meters if they struggle to keep up with bills, arguing it helps them to control how much and how often they pay for energy.
But Rosi Avis, who heads up the Manchester Branch of Citizens Advice, said remote switching is "disconnection by the backdoor".
"If customers are unaware that they are on a pre-payment meter they might not top up and therefore they are more likely to self-disconnect from their gas or electric," she explained. "
will be the last smart meter in the country if I have my way ....... and then it'll live in a lead box![]()
my attitude with 'em is .. "I've told you before - not interested, now stop bothering me on my private number - DO NOT call me again " ... haven't had a call for some time ... emails just go straight in the binYep being hounded for the yard at the moment blocked their number
No but it does still give off NOX particles which I didn't realise....." If the Whitby proposal is approved, pure hydrogen will flow through its pipes from 2025. Hydrogen's advantage is that unlike natural gas, it doesn't produce the climate-warming gas CO2 when burnt. "
So we back to diesels? I'd love to see how much my amarok actually spews out...dof,adblu etc never seen it emit anything other than water or steam...No but it does still give off NOX particles which I didn't realise.....
attitude to incompetence -- f**k 'em ...... "reported it twice" ... once would've done meI had a brand new gas installation earlier this year, smart meter the lot. Has never given them a reading so have to keep doing them manually. Won’t give me a date to come and sort it just tell me they’ll be in touch.
Had one at a customers last week that has been stuck on 00000.003 since it was fitted! I was there fitting a new boiler, apparently has reported it twice but heard nothing.
