USES4HEAT
Underground Large Scale Seasonal Energy Storage for Decarbonised and Reliable Heat
USES4HEAT is EU-funded project which aims to accelerate the decarbonization of heating and cooling by demonstrating innovative, large-scale underground seasonal thermal energy storage (UTES) solutions. By integrating them into local district heating networks, the project will harness renewable sources like waste heat, solar thermal, and geothermal energy, proving their techno-economic and environmental viability. With demonstration sites in Italy and Norway, and replication efforts in four other European cities, USES4HEAT is set to promote sustainable heating solutions across the EU.
INTERSTORES
International Innovation Network for the Development of Cost- and Environmentally Efficient Seasonal Thermal Energy Storages
The INTERSTORES Project focuses on advancing Seasonal Thermal Energy Storages (sTES) to support future energy systems that integrate diverse renewable energy sources, sector coupling, and waste heat recovery. By demonstrating two full-scale sTES variants, Reno-sTES and Giga-CTES, across Europe, the project aims to improve performance, cost efficiency, and reliability, ensuring their market acceptance and competitiveness.
THUNDER
Thermochemical Storage Utilization Enabling Data Centre Seasonal Energy Recovery
The THUNDER project aims to overcome existing barriers hampering the wide adoption of data centres' waste heat recovery strategies, providing an innovative, efficient and cost-effective Seasonal Thermal storage based on Thermochemical Materials. THUNDER solutions stretch across the value chain (data centre innovative storage providers, heat pump manufacturers and district energy company operators). The THUNDER solutions will be validated in field conditions at the Demosite in Bulgaria where the practice of waste heat recovery from data centres is not widely diffused thus boosting the market also in those areas. A deepened replicability assessment will be done and a pre-feasibility analysis developed in 10 further Demosites all over Europe. THUNDER is funded by the European Union.
PUSH-IT
Piloting Underground Storage of Heat In geoThermal reservoirs
The PUSH-IT project aims to pilot underground seasonal heat storage technologies to balance the mismatch between renewable heat supply and demand. By demonstrating these solutions at six European sites, the project supports the integration of sustainable heat into district heating networks. PUSH-IT also promotes stakeholder engagement and is developing an open-source tool to optimize storage configurations for cost-effectiveness and CO₂ reduction.
GEOSYN
Geothermal Heating & Cooling for Industry
GEOSYN focuses on promoting geothermal energy solutions for industrial heating and cooling applications. By developing innovative technologies and strategies, GEOSYN aims to enhance the adoption of geothermal systems, contributing to Europe's transition towards a sustainable and low-carbon energy future.
Platforms
Our cooperation with various platforms enhances innovation, creates more networking opportunities and promotes collaboration across diverse sectors.
The European Technology and Innovation Platform on Renewable Heating & Cooling (RHC-ETIP) brings together stakeholders from the biomass, geothermal, solar thermal, heat pump and district heating and cooling and thermal storage sectors to define a common strategy for increasing the use of renewable energy technologies for heating and cooling and phasing out fossil fuels.
