HYBUILD focuses on the development of two innovative compact hybrid electrical/thermal storage systems for stand-alone and district connected Buildings.

The project aims at developing cost-effective and environmental-friendly solutions, while ensuring comfort conditions in residential buildings located in two different climates: Mediterranean climate where cooling is critical; and Continental climate where a stronger focus is put on heating demand.

The project is led by the Spanish group COMSA Corporación and it associates 21 partners from 11 EU countries. It started in October 2017 and is running for 4 years. The project was selected as part of the Energy-efficient Buildings Public-Private partnership.

Motivation and Impact

Energy storage is a key component in providing flexibility and supporting renewable energy.

Integration in the energy System can efficiently contribute to the decarbonisation of buildings.
A promising research area is to exploit compact hybrid energy storage systems for covering space heating and/or cooling, Domestic Hot Water, and electricity demand. The overall impact is to enhance energy savings, leading to reduced greenhouse gas emissions and fossil fuel utilization, thus contributing to the EU energy security. 

HYBUILD will contribute to produce robust and innovative energy storage solutions presenting the following characteristics and advantages:

  • Cost-effective ness supported by advanced economic and business models for Investors;
  • High replicability potential to ensure an important market Penetration;
  • Easy integration (compact solutions) into existing buildings/Systems;
  • Extended solution life time;
  • Superior energy performance contributing to the overall energy system flexibility;
  • Reduction of building energy consumption and greenhouse gases.

HYBUILD innovations will be validated in three demo sites in Almatret (Spain), Aglantzia Municipality (Cyprus) and Bordeaux (France).

Role of AIT

AIT is responsible for the design of the Continental hybrid sub-system. The Continental hybrid sub-system uses a latent storage which is directly integrated into the heat pump cycle to utilize mainly sensible heat of the refrigerant after the compressor. AIT will perform system simulations of the hybrid sub-system which will help to design and control the lab-test prototype and the demo prototype. Furthermore, experimental tests of the Continental hybrid sub-system will be carried out in AIT’s laboratories under controlled environmental conditions. Additionally, AIT is work package leader of WP 3 (Hybrid storage sub-systems).
