Solar-Biomass Reversible energy system for covering a large share of energy needs in buildings

Project description

One size fits all energy solution

According to the International Energy Agency, buildings and the building sector account for 36 % of total global energy consumption and approximately 40 % of CO2 emissions. Demand for energy is growing; governments, businesses, and individuals are recognising the need to reduce dependence on fossil fuels and transition to renewable energy. EU-funded scientists are developing an important combined heat and power solution that harvests solar energy and ambient heat and also burns biomass. It is expected to meet all our heating and cooling as well as electricity needs for any building type or size without worrying about limited sunlight hours or frigid temperatures.


The SolBio-Rev project will develop a flexible energy system suitable for building integration based on renewables for covering a large share of energy demand (heating/cooling/electricity). Its flexibility is derived from the long-term collaboration of key industrial partners with research organisations, having in mind the large variety of EU buildings, especially non-residential (types, uses and sizes).
The overall objective is to develop a configuration based on renewables that allows covering all heating and cooling demand and a variable electricity demand (from zero up to even 100%) in a cost-effective manner. This configuration is based on solar, ambient and bioenergy, while it is suitable to be installed in various buildings types and sizes without any geographical restriction. The main technologies included have already proven their performance and they are combined with the aim to exploit all possible energy flows/sources, ensuring their cost-effectiveness compared to standard solutions.
The SolBio-Rev concept is based on solar thermal collectors with vacuum tubes combined with thermoelectrics, a cascade thermal chiller with electrical-driven heat pump for very high performance under cooling operation even at extreme hot conditions, a reversible heat pump/ORC for enhancing flexibility and switching operating modes between summer and winter, exploiting all available solar heat, and an advanced biomass boiler coupled with the above ORC for CHP operation. A smart control is also envisaged to manage and optimise the system operation with user-friendly features. The project also includes dissemination and communication activities to ensure outreach of its results, as well as an active participation of end-users and installers in the technology development. Moreover, exploitation activities include long-term deployment path development through a technology roadmap.
