Beer made with heat pumps is becoming a thing.

Yes, that's right - a đź§µ on the electrification of beer brewing.
1/ First up: @hepworthsbeer partnered with @futraheat & @energygovuk to install and trial their heat pump prototype at the brewery.

It recovers low grade waste heat and boosts it up to 150°C reducing fossil fuel use by up to 90%.

2/ Next is @Feldschloss1876 - they make 250 million bottles and cans of beer in Rheinfelden, Switzerland.

A heat pump makes this process more efficient and reduces the company's annual CO2 emissions by 275 tonnes.

3/ Sinebrychoff in Finland is the oldest brewery in the Nordic countries and has been labelled Finland's most energy-efficient brewery. Heat recovered from the brewing process through heat pumps now supplies around 26% of the plant’s annual heating needs.

4/ @Heineken working with @Eneco is about to install a 4 MW heat pump in the village of Zoeterwoude, the site of the largest brewery in the European Union.

5/ Ayinger Brewery in Germany uses a heat pump in the bottle cleaning process reducing energy and water consumption of this process by almost 90%.

https://t.co/pGxve7CX7Kenergie-experten.org/projekte/braue…
6/ Across the pond in the US @newbelgiumbeer partnered with @AtmosZeroSteam to introduce a 650 kW heat pump system at New Belgium Brewing’s headquarters facility in Colorado.

@newbelgiumbeer @AtmosZeroSteam 7/ In Austria people heat with waste heat from beer brewing.

Brewing beer releases lots of heat.

In this example 800 homes near the are heated using waste heat upcycled by a heat pump.

https://t.co/wQx27XFtvYbrauwelt.com/en/topics/ferm…
8/ Over in Australia @3ravensbrewery Melbourne’s Oldest Independent Brewery is fitting a heat pump to capture waste heat from the brewing process reducing their energy consumption by over 70 per cent.

https://t.co/bdHaOgutJ3foodanddrinkbusiness.com.au/news/3-ravens-…
@3ravensbrewery 9/ Austrian brewery @Mohrenbrauerei which has installed a 370 kW heat pump including a heat storage unit.

The heat pump saves the burning of
1.8 GWh/a of fossil fuels and had a payback period of less than 6 years.

https://t.co/3kP3Gt4Oy4sintef.no/globalassets/s…
10/ Dutch @Gulpener brewery installed a 650 kW heat pump in the new brewhouse, which saves 75% energy compared to the old brewhouse.

Please share more examples you can find. I'd love to extend the list!

BREAKING: A catastrophic shift in German heat policy. Fossil heating systems are getting a comeback.

While the heat transition is finally gaining real momentum, the government is sending a signal of uncertainty. Until the next energy crisis.

đź§µ Image
1) The buildings sector has been missing its climate targets for years. Watering down key provisions postpones necessary decisions and ultimately makes the transition more expensive and more chaotic.
2) The federal government has not even attempted to argue that the buildings sector’s climate targets can still be achieved despite the reform.

JETZT bestätigt: Dramatischer Kurswechsel in der deutschen Wärmepolitik.
Fossile Heizungen bekommen ein Comeback durch die HintertĂĽr.

Während die Wärmewende endlich skaliert, sendet die Politik ein Signal der Verunsicherung. Bis zur nächsten Energiekrise.

đź§µ Image
1) Der Gebäudesektor verfehlt seit Jahren seine Klimaziele. Eine Verwässerung zentraler Vorgaben verschiebt notwendige Entscheidungen und macht die Transformation am Ende teurer und chaotischer.
2) Die Bundesregierung hat noch nicht einmal versucht zu argumentieren, dass trotz der Reform die Klimaziele im Gebäudesektor noch erreicht werden können.

Today, hit a personal milestone: I lifted 2x my body weight. I could barely lift the bar 1.5 years ago.

It taught me that powerlifting principles—progressive overload and consistency—are essential for personal growth, work, and creating impact.🧵 Image
1/ Weightlifting is not mindless; it’s a strategic practice. A key principle is progressive overload, where you gradually increase the difficulty of your workouts—by adding weight, reps, or frequency—building strength, muscle, and endurance over time.
2/ Similarly, consistency is critical: showing up regularly, focusing on technique, and putting in steady effort ultimately yield results. However, this process requires patience, discipline, and resilience.

"Why are electricity prices so high if renewables break generation records and are so cheap?" I have been asked.

The main reason: Gas still sets the price 63% of the time in wholesale electricity markets in EU27 & >90% in some countries.

The graphic is from the Draghi Report. Image
For those wanting to understand why the most expensive generator dispatched sets the price I highly recommend this explainer by @LionHirth hertie-school.org/en/news/detail…
The same issue is also very prevalent in the UK market as recent @UCL_Energy analysis shows.

I love it when "experts" like Richard make sweeping claims that more wind and solar will result in more outages without ever looking at the real data.

Here's the data for Germany:

Wind + solar had a share of 33% of electricity in 2022. ➡️But there were 43% FEWER interruptions than in 2006 when wind + solar contributed only 5%.Image
1/ This is no different for other countries. Here's data from @CEERenergy on the minutes of interruptions per customer per year (SAIDI). Whilst wind and solar have seen record growth in Europe customer DO NOT experience more interruptions. ceer.eu/publication/7t…Image
2/ James Glennie also plotted grid reliability vs. wind & solar penetration in Europe and the US.

I struggle to see that places with a lot of wind and solar have more outages.

Why? Because the data doesn't show that. There simply is no correlation between grid outages and the share of wind and solar.

NEW RESEARCH: What do we do with the gas grid when gas demand drops?

A new regulatory approach is urgently needed to ensure costs for gas grid do not spiral out of control.

@RegAssistProj @heatpolicyrich @CKemfert

Free copy here 👇


Key findings in 🧵. authors.elsevier.com/a/1jJcf9C%7EIu…
Image
1/ Modelling at EU level indicates that gas demand will decline by 71-73% by 2050 as part of the path to net zero climate targets.

Importantly this includes ALL gases including hydrogen and biomethane. Even after considering alternative gases overall gas demand still declines by more than 2/3.Image
2/ Similar modelling has been done for the UK by @NationalGridESO showing that overall gas demand will decline under all scenarios. Image
