Helsinki to test nuclear district heating plant design
A pilot project to test the concept of nuclear-powered district heating systems will use electricity rather than uranium for heat generation.

Cologne gets Europe's largest river water heat pump.
Cologne is decarbonising its district heating system. To this end, a heat pump with a capacity of 150 megawatts is being built on the Rhine.
The heat pump will supply Cologne's district heating network and will be the largest river water heat pump in Europe.
Interesting insights also in the combination of solar PV and district heating (power to heat): electric boilers with very (price) responsive demand, heat pumps with 'slower' optimisation.
Bottom left graph shows how heating has become much more price responsive over the years.
Article on #Geothermal energy worth reading. Could also add direct use in #districtHeating that doesn't require deep wells.

**World’s largest CO2-based seawater heat pump goes online**
This heat pump itself, and the system it is part of (e.g. e-boiler) is responsive to the electricity system: on a huge scale what many ‘small’ residential heat pumps can also do: adjust consumption (very quickly for frequency regulation, or longer in time to match renewable electricity generation)

Many cities might even do without #HeatPumps for heating, as #geothermal resources like the #Molassebecken in Southern Germany provide valuable #hydrothermal temperatures above 70°C-100°C at moderate drilling depths.

The city of #Munich already features 6 geothermal plants, feeding #decarbonisedHeat into the 900km #DistrictHeating network.

now I continue in the collection of very large heat pumps with an earlier thread from a different platform. Time to bring those here:

"World's largest heat pump" is a lämpöpumppu (the only Finnish word I know, don't ask)
And in the competition for largest heat pumps, it is a bit like the Olympics: with many subcategories (heat source), there are many winners.

Reaching Germany's district heating goals in jeopardy after planned cuts to 2025 budget, says utilities association VKU
Goal of tripling the share of #districtheating by 2045 not achievable with current allocated funding

TIL that Denmark has district heating systems using large heat pumps even in rural villages! Something for Ireland to consider? #ClimateChange #HeatPumps #DistrictHeating

Municipalities in #Germany need to compose plans to decarbonise heating, using solutions like #DistrictHeating or ground source heat pumps. A recent study shows that new district heating infrastructure requires 44b€ investment by 2030, or 10b€ more than previously estimated. The industry calls for subsidies of 3,4 b€ per year, but actual support is a fraction of this.
3.6 million buildings are targeted for DH by 2045, equivalent to 14 million homes.

#DistrictHeating
Promising updates from the world of renewables-powered thermal energy storage and utilization!
In Finland #bioenergy is used widely for #DistrictHeating. Logging should prioritise supply of more valuable building materials that also constitute long-term carbon storage, and only logging residues burnt (to replace fossil fuels) in heat generation.
New study finds that "While biomass combustion generates direct CO2 emissions, forest fine woody debris will also be decomposed to CO2, but with a half-life of one or two decades in the studied environment"

Yesterday #Fortum, the local heating utility in Espoo, Finland, has shut down their last remaining coal plant at #Suomenoja.
One year ahead of schedule.
#DistrictHeating in #Espoo is decarbonising quickly and increasingly relies on excess heat recovery, #HeatPumps, several hundred megawatt electric boilers and #heatStorage.
