About our project.

Low-grade heat waste (-70 °C) is often widely present in several ENERGY INTENSIVE INDUSTRIES, however it can be hardly valorised using conventional technologies (e.g. Organic Ranking Cycles). Conversely, some innovative technologies (Waste Heat Recovery System-WHRS) are emerging and can provide further energy improvement and CO2 savings. 

The overall objective of HEATLEAP is to implement a number of technologies suitable for different EII (Energy Intensive Industries), to test them in a real-scale industrial environment and demonstrate their environmental and economic benefits.


Innovative Large Heat Pump (LHP) with a size of up to 7MWth output (combined with the existing heat exchangers), able to supply to district heating temperatures up to 120°C and characterized by a COP between 5 and 8, thanks also to an innovative working fluid.


Innovative Gas Expander (GEX), able to recover waste heat from decompression of natural gas from the grid and generate electricity in the range <1 MWe.


A cloud-based software platform for the system monitoring, allowing data acquisition and storage, real-time tracking of the performances with respect to the targets, data processing with artificial intelligence algorithms for outputs forecasting.

Our objectives in details.

Waste heat recovery solutions

Create a range of waste heat recovery solutions, customizable according to the different energy intensive industries requirements and type of waste heat (also low temperature), able to recover more than 70% of the available waste heat.

Reduce CO2

Reduce by 5.750 ton of CO2eq. ORI plant emissions, by recovering 22.000 MWhth/year into the production process, and by generating 2.000 MWhel/year (more than doubling the effect of the installed ORC).

Social and economic impacts

Show positive social and economic impacts, reducing the operational costs of energy intensive industries production, thereby increasing the EU’s industry competitiveness and fostering the sustainability of jobs.

Deployment of WHR

Foster the deployment of WHR solutions, at EU level, thanks to a replicability study.

Software platform

Develop a software platform able to support business decisions and strategy.

Reduce the GWP

Reduce by 99,7% the GWP of the working fluid used in the state of the art LHP, through the use of an innovative alternative fluid (i.e. R1233 ZD), contributing to the Fluorinated Gases Regulation.

Performance monitoring

Test and monitor the performances, limits and transferability of the solution to prepare its inclusion in the next BAT Document.

WHR solutions

Develop novel business models able to incentive the introduction of WHR solutions, thanks to the support of third actors (e.g. ESCOs).
