There's a real humdinger of a statement in the report behind this claim which assumes that hydrogen is *the* technology for existing homes (1/5). You ready?
'However, electric technologies such as heat pumps are
unlikely to be able to meet the elevated heat demand requirements of the existing housing stock. We have therefore assumed hydrogen will be used to
decarbonise this existing housing stock.' (2/5).
Further in: 'However, we have assumed electrification is not
suitable for older housing stock based on Element Energy and E4Tech’s Cost Analysis of Future Heat Infrastructure report which states: (3/5)
“Heat pumps operate more efficiently at lower output temperatures, and are therefore less suitable in thermally-inefficient buildings where high temperature heating may be required during cold periods” (4/5)
That report for the National Infrastructure Comission was pretty explicitly in highlighting uncertainties with costs and it was before net zero came in. Further still, AREN'T WE SUPPOSED TO BE DOING THE ENERGY EFFICIENCY ANYWAY!? (5/5)
So, a huge assumption which underpins the rest of the thinking in the report but discounts an entire pathway! And I have no idea what the counterfactual is for the £89 bill. Any ideas? (6/5).

ICYMI, Worcester Bosch, UK's largest manufacture of gas and oil boilers last week announced a £3000 support package for heat pumps subject to the introduction of the Clean Heat Market Mechanism.
But has this company really changed course so dramatically? I think not (thread).
This company, along with the other boiler manufacturers has been against this policy from the outset. Their trade body has, and continues to call it a 'soviet style' policy.
I pointed out previously that the manufactures are playing politics with their prices, as a last ditch attempt to try and stop the scheme regulations being introduced. The manus have also bee referred to the Competition and Markets Authority on this.
This is NOT straightforward. Air to water heat pumps are much simpler from a policy perspective. Air-to-air systems are extremely heterogeneous, going from a single room unit you can buy online and plug in, to a whole house heating, cooling and hot water solution.
In the UK, where the majority of homes have wet central heating, air-to-air may only have limited value. But, we know that in markets where heat pumps have grown rapidly, air-to-air systems have played a very important role.
Heating and eating. The similarities between the two sectors and the issues at play are insane. And I'm wondering if thinking about them together can help stimulate some action🧵

Decompression: Policy and regulatory options to manage the gas grid in a decarbonising UK
TLDR: As we decarbonise heating, the gas networks represent a significant liability for UK plc, and the sooner we act the better. 🧵

For a short written version you can check out this blog I wrote for @GreenAllianceUK but the briefing is rich with detail
The problem. The @theCCCuk balanced pathway suggests just 11% of homes would have any gas connection in 2050, an 87% reduction in the scale of the gas grid. Could be less owing to limits to blue hydrogen.
Heat pumps are rightly a focus of today's progress report from @theCCCuk. The tone of the buildings chapter (5) of the report is also rightly critical as commitments and plans have not come to fruition despite the development of a heat and buildings strategy 🧵
For buildings '77% of the required emissions reduction by the Sixth Carbon Budget [2033 to 2037] period [are] judged to be either at significant risk or with insufficient plans'
Of course any further delays may the risks even higher.
There is now a huge recommendations list for buildings. All of which is clearly sensible, if you are serious about the transition to clean heating.
The UK government is currently consulting on the proposed 'Clean Heat Market Mechanism' (closes 8th June).
It has the potential to be a very important industrial and energy policy.
But what exactly is it? 🧵
In simple terms, it's a scheme which requires manufactures of fossil fuel heating systems AKA boiler manufacturers, to sell a certain amount of heat pumps. A form of a mechanism we @RegAssistProj call 'Clean Heat Standards' raponline.org/knowledge-cent…
If you have been working on energy efficiency policy, it's much like a white certificate scheme: iea.org/policies/1854-…
