Horizon 2020 is the largest research and innovation program in the history of the European Union. Over the 7 years (2014-2020), a total of EUR 77,028.3 million has been allocated to innovative research. The structure of the program is based on three fundamental, mutually supportive priorities: excellent science, industrial leadership, and social challenges.

The total amount of research support is over 2.4 million EUR.

The Cracow University of Technology is the leader of the international consortium in the project, which includes leading European scientific units from Italy and the Czech Republic – Sapienza University of Rome and the Brno University Of Technology, as well as enterprises and companies from the SME sector: OILON Technology OY from Finland and F.H.U. “CZAMARA” s.c. from Limanowa and ELFRAN Nowy Targ. The end users of RESHeat system are Cracow City (ZBK) and ATER PROVINCIA DI ROMA.

Project Motivation

More than half of the annual energy consumption in households is related to space heating and air conditioning. In the European Union, home heating and domestic hot water accounts for 79% of all energy consumed by consumers. Moreover, about 75% of the energy used for these purposes is produced from fossil fuels. Switching to renewable heating and cooling technologies such as biomass boilers and solar heating systems can help reduce the use of fossil fuels. The RESHeat project consists in creating an innovative, zero-emission and autonomous energy system based only on installations using Renewable Energy Sources (RES). The system’s innovations include integrated, cooled solar panels and solar collectors equipped with solar tracking systems, as well as advanced underground energy storage systems. The aim of the latter is to achieve a high efficiency ratio of the heat pump in the long term, which will guarantee efficient underground energy storage, while reducing the amount of energy consumed by the heat pump compressor. In addition, the solution will allow the storage of heat from various sources, including low-temperature waste heat sources.

RESHeat is an energy trigeneration system, it uses renewable energy to produce electricity, heat and cold for the needs of residential and public buildings.

The basic possibilities of the proposed solution are: the use of solar energy as the main source of renewable energy, the production of heat and electricity using PVT (thermal photovoltaic) modules of the new design, the use of PVT modules and tubular vacuum solar collectors equipped with systems following the sun, in order to increase the yield solar energy, seasonal energy storage in underground heat storage, regeneration of the ground with low-temperature heat from the cooling of PVT modules, heating and cooling of the building with a heat pump .

Novelties of the system include the high coefficient of performance of a heat pump that will enable effective underground energy storage, reducing the electrical energy consumed by the heat pump compressor, as well as available heat storage from various sources.
