We bring together stakeholders from the biomass, geothermal, solar thermal and heat pump sectors to define a common strategy for increasing the use of renewable energy technologies for heating and cooling.
Our Horizontal Working Groups bring together interested experts from different technology panels to work on common horizontal topics, defined on the basis of main challenges to be addressed by the RHC-sector.
Low Temperature, Urban Waste Heat into District Heating and Cooling Networks as a Clean Source of Thermal Energy
LIFE4HeatRecovery aims to demonstrate a new generation of highly efficient district heating (DH) networks. By means of reversible heat pumps used either for heat recovery or heat utilisation, the project’s networks will recover urban waste heat sources available at low temperature, i.e. lower than 40°C. This will be demonstrated both in district heating networks operated at conventional temperature (third generation, with supply temperatures of about 70- 90°C) and in DH networks operated at low temperature (fifth generation, with supply temperatures of about 15-25°C).
Waste Heat Recovery in Industrial Drying Processes
The overall objective of the DryFiciency project is to lead energy-intensive sectors of the European manufacturing industry to high energy efficiency and a reduction of fossil carbon emissions by means of waste heat recovery to foster competitiveness, improve security of energy supply and guarantee sustainable production in Europe. The project addresses three sectors, namely brick, pet care/feed and food industry. The results are however of major relevance for a number of other energy-intensive industries such as e.g. pulp and paper industry.
Production of Solid Sustainable Energy Carriers from Biomass by Means of Torrefaction
Torrefaction is considered worldwide as a promising key technology for boosting large-scale implementation of bioenergy. It involves heating biomass in the absence of oxygen to a temperature of 200 to 320 °C. As a result, the biomass looses all its moisture and becomes easy to grind and water resistant, which reduces the risk of spontaneous ignition and biological degradation and permits outdoor storage. By combining torrefaction with pelletisation or briquetting, biomass is converted into a high-energy-density commodity solid fuel or bioenergy carrier with superior properties in view of (long-distance) transport, handling and storage, and also in many major end-use applications (e.g., co-firing in pulverised-coal fired power plants, (co-)gasification in entrained-flow gasifiers and combustion in distributed pellet boilers. Moreover, torrefaction-based bioenergy carriers may form a good starting point for biorefinery routes.
