It was a busy year last year but how did I miss Denmark setting out plans to remove all gas from homes by 2030, to be replaced with heat pumps and heat networks?
Dear the BBC. Offering a prime time radio 4 slot on heat pumps to the UK's largest gas and oil boiler manufacturer and allowing them to spout industry propaganda unchallenged is probably part of the reason we are in such a mess with heating.
On the current GB electricity generation mix, a modern air source heat pump installed in the UK will reduce GHG emissions by 74% and overall system fossil gas use by 81%.
I find it quite offensive that people still lobby against this technology. (1/3)
Great to see these 2017 Passivhauses looking fully lived in. Electrified with PV and mechanical ventilation + heat recovery, these will be some of the people in the UK, best protected from the energy crisis. To think people lobbied and continue to lobby against such standards 🧵
In case you haven't heard, Islington is doing a huge air source heat pump which extracts hot air from the tube. Heat then goes into local district heat network! And the tube gets (relatively) cooler!

This tweet from a Victorian 1895 terrace heated with a heat pump.
Have always been intrigued by how some people with zero scientific and climate credentials can be so arrogant to assume they understand things like climate. Just like covid. No scientific training, career in property and finance, telling the world about climate change.
I have become obsessed with how offshore wind is transforming the UK energy system and how the world's largest rotating machines will be cheaply and cleanly heating and powering all of our homes in the future. And you should be obsessed too (thread).
27 years until the legal UK net zero date and gas pipes going into the ground here (as across the country) with a financial life of 45 years is indicative of the need for an energy governance rip-up and redesign amiright
The war against heat pumps continues. Total misinformation here or schoolboy incompetence. Reminiscent of the Telegraph campaigning against renewable electricity a decade ago. And look how that went 🤣.
Heat pumps always were a technological cut-de-sac - expensive to run and generally unable to deliver the required heat. Electric - and possibly hydrogen - boilers are plainly the way to go
Heating is the biggest element of emissions for typical UK households. Switching to a heat pump, which reduces heating emissions currently by around two thirds, saves around 2 tonnes of carbon emissions per annum and is therefore one of the biggest climate impacts you can make.
This is the heating industry equivalent of the water industry lobbying for maintaining sewage discharges to the sea.
The centrality of heat pumps to any decarbonisation scenario, including the high gas ones, means EUA members are funding climate delay.
Burning hydrogen for heating compared to heat pumps and electrification is a poor option economically, environmentally, socially and thermodynamically. I have a new, fully referenced long-read with

Well if I used gas to heat my house that would use about 11600kWh. My heat pump uses 2814kWh of electricity. With gas making 36.8% of the UK's 2021 grid mix assuming 50% power station efficiency:
✊I've reduced total gas use by 82%.✊
The most sensible way we can reduce our exposure to the global gas market is to use less gas. In the UK we haven't got the basics right with draughty homes - and we could reduce gas use by a quarter if we sorted that out.

Staggering stats from UK
@NationalGridESO

Using electric resistive heating in 2022 was lower carbon that burning gas. An air source heat pump would have been around two thirds less carbon than gas.
Stonking package of energy efficiency and heat pump support measures released by the Government of Ireland. Looks like plans for around a 1/3 of all homes upgraded in the next decade, majority of those with a heat pump. Supported by 10 years of funding!
Heat pumps are, alongside energy efficiency measures, the critical technology for eliminating climate change causing emissions from heating across the world. We need over a billion of them by 2050 according to the historically uber conservative

If the policy is scrapped, it would mean the government has no plan whatsoever to deliver clean heating at scale which:
a. it is legally obliged to under the CC act and;
b. will mean increased (relative) exposure to gas imports.

'There is no double glazing, no central insulation in the walls, doors, windows, roof, any heat really goes straight out.'
Heat and buildings policy in the UK is now so backwards that we're building new builds, and will continue to do so for some time, that we expect to be retrofitted by 2050 while concurrently trying to retrofit existing fossil fuel heated homes.
On twitter I try to focus on clean energy issues but with an opportunity to wind up some fascist thugs I thought I should join the fabulous hashtag hijack and show solidarity with my sisters.

I've been the owner of an e-bike for almost 24 hours now and I have to say it is fabulous! Cornish hills are a thing of the past.... Unless I want them! There might just be something in this micro-e-mobility thing.
My Friday thought is that in GB we're still connecting more homes to the gas grid than we are decarbonising and we still haven't tackled the price rebalancing issue. These elements are both fundamental for the heating market transformation and we're still going backwards.
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? 🧵
Yet we continued to build to standards way lower than this with gas connections and no solar. Even the proposed 'Future Homes Standard' won't go this far in terms of fabric efficiency. IMO Passivhaus Plus with a fossil ban should be what we are aiming for as soon a practical.
I'm rarely surprised by UK energy policy any more but my jaw is on the floor having seen many comments supporting 5GW of blue hydrogen by 2030 in tomorrow's (?) strategy.
A strategy responding to a crisis caused by fossil gas proposing using more fossil gas. WTF.
The absolutely criminal thing about heat decarbonisation/heat transition politics is the total ignorance by policy makers of the value it will bring to the UK. Ignoring the carbon reductions, it will save money and pay for itself through the reductions in gas imports (thread).
What does gas lock-in look like?
This iron mains replacement work, taking place on Avenue Road in Falmouth, which is paid for by gas bills and regulated by Ofgem, is taking place in an area deemed viable for a heat network which is surrounded by heat pumpable water. (thread)
Unless you believe that there's a role for hydrogen in home heating. Which is a view that only tends to be held by people who work for gas networks, for reasons I can't quite put my finger on.
Octopus' plans to disrupt the heat pump market and deploy at scale are totally admirable and potentially game-changing. Total respect. When will the other UK suppliers follow?
The idea of a 100GW offshore wind pipeline would have been laughed at a decade ago. Now it's set to become the most important energy source for the UK.
UK offshore wind pipeline now at 98GW, according to new data from
@RenewableUK
. But just look at what is happening globally. China added 17GW in a single year. China pipeline now at 157GW(!). US gone from practically nowhere to a 83GW pipeline.
Just had a sub £100 energy bill for my average sized terraced house for typically the coldest month of the year with the house kept at 21 Degrees celcius. Heat pump plus smart tariff.
As the hydrogen trials continue, and reality continues to bite, a reminder from myself and Prof
@DavidCebon
on why the fundamentals of hydrogen for heat are so poor economically and environmentally.
Maybe I missed this yesterday but the VAT removal on solar PV, heat pumps and efficiency measures also includes zero VAT on installation. That could be a big reduction on heat pump install costs.
Energy bill just arrived. Averaging 15.1p/kWh on the 'agile' tariff. That's 4.2p/kWh per unit of heat based on my measured heat pump performance. Current gas price cap is 7.42p/kWh, that's 8.9p/kWh at 80% efficiency plus standing charges.
Less that half the price of gas.
Has always seemed BEYOND BONKERS to me that despite having a broad goal of electrifying the economy, we tax carbon in electricity but not gas and we allow votalile gas prices to set tha vast majority of power prices. And windfall tax receipts aren't even returned to consumers. 🤯
The UK has by far the highest ratio of Electricity price to Gas price.
This is a result of Tory Government policies:
1. Gas for electricity incurs a Carbon Tax, whereas gas for boilers does not.
2. The price of ALL electricity is set by the price of Gas-fired electricity.

In 2018, the National Infrastructure Commission assumed a heat pump sCOP of 2.5 in its analysis.
The Electrification of Heat trial from 2021 (during covid) gave 2.8 measured.
I'm getting 3.7.
We're now seeing real world sCOPs of over 4.
This innovation is great! (1/n)
There is a wealth of expertise and evidence on what is a sensible path for decarbonisation of heat in the UK. Having worked on multiple biogas projects and having worked on this issue for over a decade, this idea that we can use biogas at scale for heat can be dismissed (thread)

Remember when we were told this was a 'drop in solution'? Full of holes more like!
Also 'mechanically ventilated buildings are excluded from the trial'.
Despite the importance of hydrogen for decarbonisation (primarily of industry), there are still some fundamentals that do not always seem to be appreciated by policy maker and which are ignored by much of the incumbent gas industry but which need to be considered.

They're in Hayle, Cornwall and I did a tour with students while they were being built. I remember thinking 'none of this is rocket science' but all all it took was a progressive developer. There's a policy message there!
For years, many of us have been calling out the greenwashing and climate delay dangers of hydrogen for heating while the gas companies and their trade bodies have called us activists, vested interests and personally attacked us and scientific research.
Karma winning today.
“We’re actually testing a heat pump in our lab this spring where the cutoff temperature is –31 degrees Fahrenheit,” she says. “That was unheard of 10 years ago.”
Do people realise just how much gas the UK imports? And how much and how quickly remaining gas production is is expected to fall? I feel like I'm watching a slow motion train crash. And we absolutely do not have a proper plan.
The thing I don't get about the anti-efficiency, anti-heat pump pro-gas lot is, are you really happy with an ever increasing reliance on gas imports? Are you actually happy for the UK economy to be that exposed?
As you may have seen, The National Infrastructure Commission has released its 2nd infrastructure assessment, 5 years after the 1st. The big heating headline is basically 'hydrogen for heating is dead' which I think we already knew, but a good kick for the government. (1/N)

Ripping out existing boilers across 24 million homes across the UK is utterly absurd.
It will lead to heating chaos for millions of people and general resentment towards the UK’s drive to net zero.
Important (IMO) 👇
When retrofitting a building from a boiler to a heat pump, the first time costs will be significantly higher than all subsequent heat pump replacements. This one-off investment will last in perpetuity yet this fact is rarely appreciated (thread).

If there was ever a time to set out the plans for a national energy efficiency transformation programme, and I mean getting every house to at least EPC B, it is now.
However, our exposure to volatile global gas prices underscores the importance of our plan to build a strong, home-grown renewable energy sector to further reduce our reliance on fossil fuels.
Renewable energy has quadrupled since 2010, but there is more to do (6/7)
Workings:
Based on 9000kWh heat demand = 10588 units of fossil gas in a boiler. COP of 3.5 = 2571 kWh of electric for HP. Current grid mix 39.6% gas (Digest UKEIB 22) CCGT efficiency of 50% (DUKES 22) . 2021 UK gov conversion factors. (3/3)
The results are in and my air source heat pump has given me a total system performance factor* of 3.48 between 15th October and 15th January (colder than average). I love the fact that 71% of the heat in my house has been extracted from the air.
