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.
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.
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.
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.
2/ Similar modelling has been done for the UK by @NationalGridESO showing that overall gas demand will decline under all scenarios.
How to reduce the vast amount of operational emissions from buildings from heating, cooling and appliances?
Today I delivered a scene setting presentation at a United Nations Framework Convention on Climate Change event. Some key takeaways from my presentation in this 🧵
1/ Until recently operational emissions from buildings were the elephant in the room. This is changing now with more attention being paid to them.
2/ In 2022, operational energy demand in buildings (for space heating and cooling, water heating, lighting, cooking and other uses) accounted for a whopping 30 per cent of final energy demand. 27% of total global CO2 emissions are from operational energy use in buildings.
1/ Many uninsulated homes and buildings are already heated to comfortable temperatures with heat pumps, as shown across multiple case studies, including an uninsulated stone church. isoenergy.co.uk/projects#sort=…
2/ A building loses heat through the walls, the windows and the roof when it is colder outside than inside, as shown by the stylised arrows in the figure in the main post above. The upper panels show an outdoor temperature of 10C, coloured purple, and an indoor temperature of 20C, coloured red.
Energy transition critics often point to primary energy use to demonstrate that it's going to be impossible.
But 72% of the global energy input is currently lost after conversion.
The problem we're trying to solve here is a lot smaller than primary energy use might suggest.🧵
1/ The future energy system will be characterised by a lot more "electricity-only" renewables (mainly solar and wind). Many of the conversion losses are currently due conversion losses at the electricity generation stage. This will no longer be anywhere near as significant in a system dominated by solar and wind.
2/ All end-use sectors will use significantly more electricity. This will result in much higher end-use efficiency and globally could reduce final energy use by up to 40%.
