Integrated Thermal energy Storages for Zero Emission Buildings

Solutions developed

Low2HighDH is a 3-year project supporting 30 high temperature district heating sites (HT DHC) in Lithuania, Poland, and Slovakia in the implementation process of low-grade or waste heat technologies, by promoting the advantages of these energy sources and providing them with an investment plan to fulfil the proposed criteria for ‘efficient district heating and cooling’ from the Energy Efficiency Directive within a 10-year timeframe.

Main results

The Low2HighDH project supports 30 high-temperature district heating sites in Lithuania, Poland, and Slovakia, promoting low-grade or waste heat technologies. It launches RFQs to select suppliers for solar thermal, geothermal, and heat pump implementations. Capacity-building materials disseminate technical and financial solutions, fostering engagement through stakeholder networks. With an expected EUR 454 million investment, the project aims to replace 1 TWh/year of fossil fuels, abating 291 thousand tons of CO2 emissions, aligning with the Energy Efficiency Directive's goals within a 10-year timeframe.
