EU LIFE - LIFE4HeatRecovery - Low Temperature, Urban Waste Heat into District Heating and Cooling Networks as a Clean Source of Thermal Energy

LIFE4HeatRecovery will demonstrate a new generation of highly efficient district heating networks, which will be able to

- recover urban waste heat sources available at low temperature, i.e. lower than 40°C,

- in DH networks operated at conventional temperatures (3rd generation working around 70 to 90°C) or low temperature (5th generation at 10 to 25°C),

- by means of reversible heat pumps used either at heat recovery and or heat utilisation sides.

In particular, the LIFE4HeatRecovery networks will pursue the following objectives:

OBJECTIVE 1. TO DEMONSTRATE OPPORTUNITY AND EFFECTIVENESS OF WASTE HEAT RECOVERY FROM MULTIPLE URBAN SOURCES

New generation DH networks operated at very low temperatures can directly recover heat rejected by chillers (at around 30 to 40°C, e.g. from air-conditioners, supermarkets’ refrigeration and industrial processes), using rejected heat to cover heating needs in other buildings.

However, a large number of high temperature 3rd generation DH network exists, which normally can recover thermal energy only from high temperature industrial processes. In these cases, high-temperature water-to-water heat pumps are needed to rise the temperature of the heat rejected to the network’s levels.

OBJECTIVE 2. TO DEMONSTRATE MANAGEMENT STRATEGIES FOR DH NETWORK suitable to prioritise the harvest of waste energy sources compared to fossil fuels utilisation

interact with the electricity grid to negotiate the best prices from utility and customers perspectives for the electricity used by the heat pumps

OBJECTIVE 3. TO DEMONSTRATE TRADING SCHEMES allowing to manage thermal energy fed/purchased by/from different customers. The schemes are BUSINESS MODELS elaborated by the utility companies involved in the project.

With LIFE4HeatRecovery, customers assume both the role of energy consumers and producers. Trading schemes will be elaborated having the energy users as a focal point, trying to gather social acceptance and triggering the wide adoption of the solutions.

OBJECTIVE 4. TO DEVELOP FINANCIAL SCHEMES ENABLING LARGE PUBLIC AND PRIVATE INVESTMENTS TO BE MOBILIZED

LIFE4HeatRecovery activities will also be focused on the development of innovative financing mechanisms based on public-private collaboration, contributing to the uptake and large-scale replication of reliable business cases.

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.
