I'm sick and tired of people claiming "Heat pumps don't work in Britain" such as @CalumDouglas1 commenting on my LinkedIn Post.
Heat pumps can work in any building if designed and installed well. They don't care much about national borders.
1) Summary of ongoing @beisgovuk heat electrification trial:
-"most homes are technically suitable for a heat pump"
-"running costs [...] generally [...] have been similar or lower than previous fossil fuel heating costs."
-"participants generally satisfied with their heat pumps"
3) Using single cases where people had a shoddy installation, a poor design or poorly maintained heat pump is not evidence that heat pumps don't work in Britain. It is evidence that someone should have chosen a different installer.
4) Another reminder that in the coldest parts of Europe about half of the population has a heat pump. And no, people in Norway, Sweden and Finland are not freezing in the winter.
5) The old British housing stock is often used as an argument why heat pumps supposedly "don't work". But there are plenty of examples of heat pumps in old buildings working well.
7) The UK government @beisgovuk@10DowningStreet have identified heat pumps as a key technology for heating decarbonisation. By 2028 they want to see 600,000 heat pumps to be installed every year. Policy to deliver on this pledge is underway. gov.uk/government/pub…
8) @theCCCuk also looked at how to decarbonise heating in the UK. Heat pumps have been identified as the key heat supply technology to reduce emissions for net zero. 75% of low carbon heating systems expected to be heat pumps by 2030. theccc.org.uk/publication/si…
2) This study coming out of Australia uses IPCC emission factors for fugitive emissions and longer Global Warming Potential time horizons (100 year not 200 years) than the Howarth & Jacobson study. It also provides estimates for up to 90% capture.
People often ask me whether I’m for or against hydrogen. But that is the wrong question to ask.
Instead the question should be “In which use cases can hydrogen deliver decarbonisation where other solutions are either not available or more costly?”
1) Hydrogen appears to be currently peaking on a “hype cycle” i.e., the current expectations are inflated far beyond its likely impact.
2) Clearly, the fossil fuel industry has a vested interest in maintaining its existing business model, and its strong support for blue hydrogen is primarily driven by self-preservation rather than climate protection concerns.
1) Banning fossil fuel heating by 2035: The document is not entirely clear what is being planned. It talks about setting an 'ambition' but it remains unclear whether this means setting an outright ban of installing new fossil fuel heating systems.
2) The document also talks about the 'aim' to phase out new natural gas boilers by 2035 and highlights the potential for further policy. Further detail needs to be seen before we can be confident that 2035 is a hard regulatory stop.
🚫Ban of fossil heating systems to be installed after 2035
This is a huge step. The UK is the first country in the world doing this and it replicates what we have already for petrol and diesel cars. Details to be seen yet but a big step forward.
💷£450m grants for heat pumps
The current funding policy for heat pumps will run out next year and has been generous. £450m over 3 years translates into 30,000 heat pumps per year. That’s not enough to get us on track to 600,000 per year and supports current installation levels.
1) It is widely accepted that heat pumps will play a major role for decarbonising heating. But their running costs are usually higher than gas boilers. This is because we put most of the climate policy costs on electricity and almost none on fossil fuels.
