EU H2020 REWARDHeat - Renewable and Waste Heat Recovery for Competitive District Heating and Cooling Networks

EU H2020 REWARDHeat
  • Project duration: September 2019 - September 2023
  • Project status:
    Ongoing
  • Funding:
    Societal Challenge (Horizon 2020 /EU funding /Project)
  • Total project budget: €19,023,298.75

It is in urban areas that the demand for heating and cooling demand assumes highest density. At the same time a huge amount of low-grade waste heat is diffused within the urban texture, the largest amount being rejected by air-conditioners, cooling systems in industrial processes and tertiary buildings (i.e. dry coolers and wet cooling towers), datacentres’ chillers and supermarkets’ refrigeration systems.
Moreover, for historic reasons, cities have born along rivers, lakes and seashores. All these sources make low-temperature renewable energy available, which utilisation is highly replicable because it is accessible right where it is needed.
Having this in mind, the overall objective of REWARDHeat is to demonstrate a new generation of low-temperature district heating and cooling networks, which will be able to recover low-grade renewable and waste heat available at low temperature. Focusing on the exploitation of the energy sources available within the urban context allows maximizing the replicability potential of the decentralized solutions developed in the project.
REWARDHeat will promote punctual metering, thermal storage management, network smart control as means to enable and optimise the exploitation of renewable and waste heat in DHC networks.
At the same time, this approach permits a change of paradigm with respect to the business models devised: thermal energy will not be seen as a commodity anymore, rather it will be sold as a service to the customers.

72% of the European population (EU28) lives in urban areas - defined as cities, towns and suburbs:41% live cities and 31% in towns and suburbs1. It is in urban areas that the demand for heating and cooling demand assumes highest density. At the same time a huge amount of low-grade waste heat is diffused within the urban texture, the largest amount being rejected by air-conditioners, cooling systems in industrial processes and tertiary buildings (i.e. dry coolers and wet cooling towers), chillers of refrigeration systems and service facilities, e.g. sewer pipes. Datacentres’ chillers and supermarkets’ refrigeration cabinets release a massive quantity of thermal energy: the refrigeration process in an average-size supermarket represents 50% of its energy uses and can cover the heating needs of 200 apartments.
Moreover, for historic reasons, cities and towns have born along rivers, lakes and seashores. All these sources make low-temperature renewable energy available, which utilisation is highly replicable because it is accessible right where it is needed. Having this in mind, the overall objective of REWARDHeat is to demonstrate a new generation of highly efficient district heating and cooling (DHC) networks at TRL 6, which will be able to increase production and distribution efficiency by recovering, renewable and waste heat available at low temperature, i.e. lower than 40°C. Focus is on the exploitation of the energy sources available within the urban context, allowing to maximize the replicability and upscale potential of the decentralized solutions developed in the project. The REWARDHeat solutions promote a cost efficient and technically viable decarbonization of the European DHC sector.
In REWARDHeat we gather low temperature heat that cannot be used elsehow to replace fossil fuels driven boilers installed at residential and tertiary buildings. It has three positive effects:
• the Primary Energy use and GHG emissions are largely reduced
• the pollutants emitted from single (gas or oil driven) boilers replaced are avoided
• the heat island effect is reduced as heat rejected in the environment from human activities is recycled and maintained into buildings.
To meet the overall objective of the proposal four subordinate goals have been derived.
OBJECTIVE 1. TO INTEGRATE EFFECTIVELY MULTIPLE URBAN RENEWABLE AND WASTE ENERGY SOURCES

OBJECTIVE 2. TO DEVELOP INNOVATIVE TECHNOLOGIES FOR FLEXIBLE USE OF HEAT IN DHC NETWORKS

OBJECTIVE 3. TO DEMONSTRATE DIGITALISATION SOLUTIONS ALLOWING TO OPTIMISE THE MANAGEMENT OF THE DHC NETWORK

OBJECTIVE 4. TO DEVELOP BUSINESS MODELS AND FINANCIAL SCHEMES TO ENABLE LARGE PUBLIC AND PRIVATE INVESTMENTS TO BE MOBILIZED

Eurac Research is a private research center based in Bolzano (South Tyrol) with researchers from a wide variety of scientific fields who come from all over the globe. Together, through scientific knowledge and research, they share the goal of shaping the future.

What we do

Our research addresses the greatest challenges facing us in the future: people need health, energy, well-functioning political and social systems and an intact environment. These are complex questions, and we are seeking the answers in the interaction between many different disciplines. In so doing, our research work embraces three major themes: regions fit for living in, diversity as a life-enhancing feature, a healthy society.
