Chris Baraniuk has been on a quest to find the biggest heat pump-powered projects in Great Britain.
Here's what he found. A fun and inspiring read.👇

2024-12-17 15:26:09 UTC

Did you know that heat pumps are good for your health?
Replacing oil and gas boilers eliminates in-home fossil-fuel combustion that vents pollutants like ammonia, sulfur dioxide, and nitrogen dioxide into the outside air.

2024-12-13 07:53:46 UTC

Cost of electricity relative to fossil fuels is key factor when it comes to industrial electrification.
In most EU countries electricity is taxed more & renewable energy support levies are often put on electricity & not on fossil fuels.

A remarkable transition:
Kenya is Africa's leading country when it comes to renewables.
In 2000 fossil fuels contributed 60% to electricity generation.
Today it is 6%. In 2023 electricity was from almost 50% geothermal, 20% wind+solar and 22% hydro.

What do we do with the gas grid when gas demand is in terminal decline?

One type of comment on renewables I get frequently is from people who show primary energy demand.
They say “We will never be able to replace this with renewable energy.”
I tend to differ. Here’s why.👇

1 in 4 cars sold in the UK in November were electric.
Despite all the negativity in the media about EV sales being down and so on - the market keeps on growing.
Too often media reports just reflect the author's own dislike of EVs more than anything.

I thought the discussion around hydrogen for heating was pretty much over.
But I keep seeing people postulate that hydrogen for heating will play a role in the future.
I highly doubt that. Why? Because the 54 independent studies I reviewed suggest otherwise.

Energy efficiency needs a radical rethink.
Making fossil fuel technologies & processes incrementally more efficient is no longer enough.
It might even perpetuate their use.
In my new article I explore how energy efficiency needs to evolve to remain relevant.
https://medium.com/p/41741abea59b

2024-11-22 11:13:37 UTC

Why I’m optimistic about the energy transition:
Watch my recent keynote at the Euroheat and Power conference in Brussels in full.
We tend to underestimate new technologies and innovation, and we tend to overestimate the inertia of incumbent technologies.

2024-11-21 14:23:21 UTC

Have we been duped by the primary energy fallacy?
Critics of renewables often say that we cannot possibly replace the vast amount of fossil fuel we currently use with clean energy.
The good news is that we don’t have to. My article in Medium explains why.

Cold climate heat pumps have arrived.
Even down to -25C some models still deliver heat with an efficiency superior to fossil fuel heating systems.
https://www.washingtonpost.com/climate-solutions/2024/11/14/cold-climate-heat-pump-winter/

2024-11-12 09:46:30 UTC

I keep hearing that heat pumps are a niche technology and will never take off.
Look at the market share of heat pumps in different European countries - in 8 countries most new heating systems installed are now heat pumps.
https://sfo3.digitaloceanspaces.com/cdn.mastodon.energy/media_attachments/files/113/469/344/221/199/048/original/3d61568aac770a20.png

2024-11-11 18:14:39 UTC

Crazy fact:
Even if you just installed a new gas boiler ripping it out and replacing it with a heat pump makes sense from a carbon perspective.
Carbon emissions associated with manufacturing the boiler and the heat pump are offset in less than 2 years.
After that the heat pump will save carbon year on year.

2024-11-11 09:46:08 UTC

Our current energy system is extremely wasteful.
More than 2/3 of primary energy inputs end up as waste heat.
Yet the customer has to pay for all of the energy in the left hand side of this chart to get the small amount of energy converted to energy services.

Most people don’t know this.
Heat pumps REDUCE gas consumption even if running 100% on electricity from a gas fired power plant.

No we don’t have to replace all fossil primary energy.
We only have to replace the useful energy with clean energy using much more efficient technologies.
We don’t need to replace the wasted fossil energy. We can avoid the inefficiency in the first place.

This is a great illustration of what the new energy order looks like:
➡️ large to small
➡️ centralised to decentralised
➡️ large grids to microgrids
➡️ one-directional to bi-directional
➡️ passive consumers to active prosumers
Of course this is simplified and highly stylised but it shows the direction of travel.

Gas networks fees in Germany are on the rise.
This is because
a) fewer and fewer people use the gas network and
b) gas network assets are now depreciated faster to avoid stranded assets and costs later down the line as Germany approaches its 2045 net zero target.
Those who installed a new gas boiler following the advice from some commentators now find themselves with rising heating costs.

When people think about leading countries in renewable energy they rarely think about Lithuania.
The country has now reached a whopping 60% of wind + solar as a share of total electricity generation making it number 3 in the world.
In 2012 gas still supplied 64% of Lithuania's electricity. It's now down to about 10%.

I was asked: Why do you think heat pumps are great?
Simple: Heat pumps are the most efficient heating technology ever invented. Why is that? Because rather than burning a fuel heat pumps simply capture, compress and transport pre-existing heat from the air, the ground or the water and put it into buildings. And they do this by using electricity that is getting cleaner by the day.

Heat pumps work when it's cold.
Our research shows: In fact they are much more efficient than fossil fuel systems even at sub-zero temperatures.

Next generation heat pumps can work in the extreme cold:
Carrier HVAC will shortly launch new units that operate reliably at 100% capacity down to -30C according the lab and field tests.

The EU’s wind and solar power generation surpassed fossil fuel generation in the last 12 months.

WHAT A BEAST!
Finland’s capital city, Helsinki, is building one of the world’s largest heat pumps to keep as many as 30,000 homes warm in the winter while reducing carbon emissions.
I say “one of the world’s largest” as it depends on whether you aggregate heat pump units in a single project or not. The main message here is: This thing is HUGE!

THIS IS A HUGE ACHIEVEMENT:
The EU now generates more electricity from wind and solar than from fossil fuels.

The UK government‘s target for near zero emissions electricity by 2030 will require monumental change.
Doubters will say that it‘s impossible. But if you said 10 years ago that in 2024 coal would be gone many would have laughed at you.

$7 trillion per year - that’s the amount of fossil fuel subsidies the world provides according to the the International Monetary Fund.
This includes both direct and indirect subsidies.

Range anxiety is frequently cited as one of the biggest turnoffs of electric vehicles.
Even as recent as 2021, the average range of an EV was just 217 miles (349 km), falling significantly short from the average gas car’s range of 413 miles (665 km).
Thankfully, as this infographic shows, EVs with over 300 miles of range are becoming more common.
Below are the top 10 EVs for 2023, ranked by their EPA combined driving range.

Over the first 7 months of 2024, renewables comprised 30.2% of electricity - nearly double the levels seen just three years ago.

Coal once provided 70% of UK electricity. Soon it will be 0%:
On September 30, 2024, the UK's last remaining coal-fired power station, Ratcliffe-on-Soar in Nottinghamshire, will close.

So much energy is getting wasted.
Here's Germany: Almost 2/3 of primary energy is lost in conversion processes as waste heat.
Luckily we do not have to replace all of this energy as renewable energy, electrification and efficiency result in a vastly more efficient energy system.

"If wind & solar were the answer, China would be building them at record speed." someone replied to my post on UK coal phase-out on X.

This Nature paper says yes.
Most surprisingly this is AFTER including short- and long-term storage costs for renewable energy sources.

Sweden is a global heat pump leader.
How have they managed to phase out fossil heating oil and deploy millions of heat pumps over a period of 20 years despite having one of the coldest climates in Europe?

Yes heat pumps work in very old buildings.
Here's an 11th century Norman church in Lympne, Kent that has been fitted with a heat pump.
My own 1880 Victorian house had a heat pump fitted in 2019 and it works very well.

When horses were replaced by cars there was a lot of resistance & scaremongering by the incumbent horse industry.
Here's an old anti car advert by a horse carriage company.
Technology transitions are always characterised by resistance from incumbents who want to keep their assets and continue to gain from them.
