These will be tackled by Task 45, the follow-up of IEA-ES Task 39. This new project will run from 2024 to 2027 and aims to leverage insights from the previous task. In parallel, the EU- funded project “TREASURE” will focus on demonstrating PTES in five European countries, building upon reference initiatives like the PTES in Høje Taastrup.
next enabling technology for integrating Renewable Energy.” This potential can only be supported by using LTES, which in turn needs to be widely implemented.
Within Task 39, the policy workshop has highlighted the main challenges and opportunities for the vast deployment of LTES:
raising awareness about LTES technologies, demonstrating their robustness, and illustrating typical implementation process from idea to commissioning

reducing uncertainties by facilitating the permitting process and increasing standardization
1 GWh (1,000 MWh) is enough heat to supply the demand of 62 households for one year. Households in Denmark consume, on average, 16 MWh/year for space heating and hot water in 2020. (Source: Danish Energy Agency)
shortening the realization time of LTES by sharing experiences and involving all stakeholders
decreasing costs through materials and process development and industrial network expansion
The PTES in Høje Taastrup serves three CHP plants and three waste-to-energy plants (partners in the project). Optimizing electricity production (sector coupling) and reducing peak production in the Copenhagen area is expected to represent 27.4 TJ of fuel saved/year and a total CO2 reduction of 6,200 tons/year. The total investment is 10.7 Mio €. The simple payback period is 12 years.
What are IEA-ES Task 35 and Task 39? A Task is an activity in the Energy Storage Technology Collaboration Programme (“TCP”) of the International Energy Agency (“IEA-ES”). It is working on a specific topic: Large Thermal Energy Storages (LTES) for Task 39. Task 39 gathers 60 experts from 36 institutions and 11 countries: Austria, Canada, Denmark, France, Germany, Italy, the Netherlands, Sweden, Turkey, the UK, and the USA.
