Decarbonise Heating UK

Communicating the UK's toughest net-zero challenge

@FarrowMP @janrosenow @IEA It's more than a caveat: by number of units, there's almost as many solar thermal units by 2050 as there are gas boilers now!

[Decarbonise Heating UK @decarboniseheat]

@robertjwhitney The original source sees a very small future for heating that involves burning stuff, so it's a reasonable approximation, even if some H2 for heat is allowed.

An complete and eminently sensible policy package for delivering subsidy-free heat pumps for all. Hopefully someone is listening... @CommonsBEIS

How to make heat pumps "subsidy free"

By Michael Lewis, UK boss of EOn, drawing on new @PublicFirst_PF report

1⃣CO2 tax on fossil heating
2⃣move renewable subsidies to general taxation
3⃣economies of scale to halve costs
4⃣cheap loans via Nat Inf Bank

[Decarbonise Heating UK @decarboniseheat]

@janrosenow Ah, my mistake! I see fig 11 now.
That's what comes of trying to read things on a bus.

[Decarbonise Heating UK @decarboniseheat]

@janrosenow Cost parity by balancing levies alone.

[Decarbonise Heating UK @decarboniseheat]

@janrosenow 17.5p per kwh electricity? Surely agile/time of use tariffs should be part of the analysis.

[Decarbonise Heating UK @decarboniseheat]

@mikefosterEUA Oh dear, that's not very nice. Whatever you call it, you're still using the wrong variable to make your point. Maybe look at the EBIT from suppliers consolidated segmental reports, (https://t.co/OZi7TWHIXQ), divide by kWH and try again?

@JonathanWaxman1 @DavidDye9 @robertjwhitney @CadentGasLtd @KeeleUniversity ... probably by a gas power station. So it ends up being just a less efficient, so more carbon intensive, natural gas boiler.

[Decarbonise Heating UK @decarboniseheat]

@JonathanWaxman1 @DavidDye9 @robertjwhitney @CadentGasLtd @KeeleUniversity Even if 'green' hydrogen, unless the electricity generation would have otherwise been curtailed, then it will be increasing emissions. The reason being that the extra energy needed due to the inefficiency of hydrogen as an energy vector has to be met by more generation...

@Pylon54 @IanStockport @david_sykes89 @platospal @CommonsBEIS Now try it with @octopus_energy agile, if you were to run your heat pump at off-peak times.

@FarrowMP @heatpolicyrich @kenbone44 @baldwinbiogas @Zain_Habib @AbigailDombey @ELPinchbeck The caveat for 'mostly' being that coefficient of performance needs to be above 2, but this is usually the case.

[Decarbonise Heating UK @decarboniseheat]

@FarrowMP @heatpolicyrich @kenbone44 @baldwinbiogas @Zain_Habib @AbigailDombey @ELPinchbeck Ah no, even if all the electricity is from gas power stations (worst case), most of the heat is still from the surroundings (warmed renewably by the sun) and the heat pump just moves this renewable energy inside.

[Decarbonise Heating UK @decarboniseheat]

@robertjwhitney And how many gas boilers are installed optimally? ;) can't let the best be the enemy of the good.

[Decarbonise Heating UK @decarboniseheat]

@heatpolicyrich @kenbone44 @baldwinbiogas @Zain_Habib @AbigailDombey @ELPinchbeck Or just 'mostly renewable', or...

[Decarbonise Heating UK @decarboniseheat]

@heatpolicyrich @kenbone44 @baldwinbiogas @Zain_Habib @AbigailDombey @ELPinchbeck So maybe the new category could be something snappy, like: 'even in the worst case scenario, mostly renewable'.

@JonathanWaxman1 Euripides trousers, Eumenides trousers.

[Decarbonise Heating UK @decarboniseheat]

@JonathanWaxman1 Yes :)
