The #DistrictHeating operator in #Nuremberg finds in study that #SeasonalStorage of heat is feasible to achieve #decarbonisation targets, store excess heat from summer for winter demand and overcome #Dunkelflaute of 4-6 days and even up to 1 month (160 GWh stored) magazin.n-ergie.de/presse/fau-u...

FAU und Ohm nehmen saisonale Wärmespeicher in den Fokus – N-ERGIE Magazin

Welche Technologien eignen sich besonders, um Wärme zu speichern? Damit haben sich die Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) und die Technische Hochschule Nürnberg Georg Simon Ohm in zwei aufeinander aufbauenden Studien beschäftigt.

Great thread!
The pace of #SectorCoupling is amazing!

In Helsinki 🇫🇮 it's not only #HeatPumps:
https://www.helen.fi/en/about-us/energy/energy-production/power-plants

Katri Vala
165MW heat + 100 MW cool

Esplanadi
22MW heat + 50MW cool

Eiranranta (2025)
90MW heat + 60MW cool

... but also #SeasonalStorage:

Mustikkamaa (2021):
260.000 m3

Kruunuvuorenranta (2030):
300.000 m3

#ElectricBoilers are also being built promptly in 🇫🇮 as there is often cheap wind power available in winter.

Power plants | Helen

We produce heat, electricity and cooling in power plants and heating plants in different parts of Helsinki. Find out about the power plants and their production outputs.

Finnish leading #solarThermal system supplier #Meriaura (formerly #Savosolar) to deliver
5,800-square-metre (62,431 sq ft) #solarCollector system to Les Serres Vermeil SARL, an organic vegetables producer based in Palau-del-Vidre, southern France .
The thermal power should be around 4MW.

The company serves customers in district heating, process heat and agroindustry. Ideally, the systems could include #SeasonalStorage.

Solar heat as a solution - Meriaura Energy

Solar heat as a solution Solar heat for industrial processes Solar heat for industrial processes (SHIP) continues its steady growth. Thirty-two per cent of the world’s energy demand is used by industry, and around 75% of this is for heat. Of industrial heat use, some 30% is low temperature heat (<150 °C), which is particularly… Continue reading Solar heat as a solution

Construction of the world's largest heat storage facility #Varanto to begin in June in Vantaa, Finland. Surplus heat from the adjacent Waste2Energy plant in summer can be stored for winter use. This #CavernThermalEnergyStorage also features two 60 MW electric boilers to use cheap #WindPower when available.

90 GWh, Tmax 140 °C, water volume 1.100.000 m2 cost 200 M€ incl. 19 M€ govt. grant, but no updates on schedule

@janhaverkamp @gimulnautti Technically reliable, competitive and more quickly deployable alternatives like building #EnergyEfficiency upgrades, #SeasonalStorage of heat and low-temperature bi-directional #districtHeating receive less public attention. Awareness on #spotPrice is improving, as well as demand flexibility. But most news coverage still regards price volatility a major problem instead of an opportunity to develop storage solutions and exploit the cheap hours of abundant #WindPower

Work on 90GWh thermal energy storage as part of Vantaa district heating could start next year. This one million m³ cavern for of heated water looks to become world's first seasonal thermal energy storage system. #energy #seasonalstorage

@gimulnautti @janhaverkamp Plenty of market-based, renewable and reliable technologies already exist in Finland to ensure renewable heat supply through winter. Industrial and municipal CHP incl W2E, biogas/biomass boilers & sustainable local feedstocks, hydro, semi-deep boreholes & regenerative geoenergy etc. Near zero energy buildings reduce demand.

Several heat storage facilities are and will be built, incl. world's largest #SeasonalStorage site in Vantaa.

Vantaa seasonal heat storage

The world's largest seasonal heat storage facility is being built in Vantaa, Finland, using an alliance model. In the alliance, YIT, AFRY and Vantaa Energy will jointly design and build a unique, modern and sustainable heat storage facility.

@Sustainable2050 @martinvermeer There are indeed hydrogen projects underway but can they scale up quickly enough? Adding 2 or 3 GW of wind each year is quite a pace, and capacity factors are also improving.
I assume part will go to heating, but we also need new heat storage capacity in district heating networks to absorb that wind energy when available, and cover few days of dunkelflaute.

One #SeasonalStorage is being built in Vantaa, but it takes 5 years..

#Helsinki energy utility Helen invests100M€ (incl. 14M€ govt. grant) in new #heatPump to produce 90MWth #DistrictHeat and 60MWth #DistrictCooling.
Heat source is wastewater, that has already delivered heat to the #KatriVala heat pump station, but with heat remaining.

Heat pump should be operational in late 2025 and deliver 460 GWh/a heat.

Too bad #SeasonalStorage is not included in this project, that could add value when power price volatility increases.

Työ- ja elinkeinoministeriö on myöntänyt investointitukea Helenin uudelle Eiranrannan lämpöpumppulaitokselle

Helen rakentaa Etelä-Helsinkiin uuden lämpöpumppulaitoksen, jolla tuotetaan hiilineutraalia kaukolämpöä ja kaukojäähdytystä puhdistetun jäteveden hukkaenergiasta. Huipputehokkaassa laitoksessa lämpöä saadaan tuotettua poikkeuksellisen matalalämpöisestä vedestä, jota on hyödynnetty kaukolämmön tuotantoon jo kertaalleen Katri Valan lämpöpumppulaitoksessa. Investoinnin kokonaisarvo on noin 100 miljoonaa euroa, ja sille on myönnetty noin 14,5 miljoonaa euroa työ- ja elinkeinoministeriön energiainvestointitukea.

The fokus should now be on quick solutions that work, like #energyEfficiency, #insulation and #heatRecovery in existing building stock, and automation for #DemandSideManagement. Thermal #SeasonalStorage and bidirectional low-temperature #DistrictHeating should also be expedited. #Biogas has plenty potential still unused. #SolarEnergy both PV and thermal, will provide cheap energy March-October.
