Advanced Thermochemical Technology for Waste Heat Recovery

The ambition of TechUPGRADE is to develop and demonstrate (to TRL 5) this radically new idea by the development and operation of two separate first-of-its-kind and compact heat upgrade systems integrated with industrial waste heat and solar thermal collectors (also district heating as an add-on) under relevant environmental conditions. These systems will be capable of performing simultaneously the following two functions:

• Upgrading the low-temperature heat to higher temperatures (150-250 ^oC) by tuning the partial pressure of water vapor consuming a small amount of electricity. It will provide a radically new way of upgrading the heat in comparison to conventional heat pump (VCHP Variable Capacity Heat Pump or Thermo Acoustic Heat Pumpt TAHP), which are mainly driven by electricity.
• It will provide inherent heat storage capability within the system (if needed), thus providing flexibility in the supply of process heat when integrated with other sources such as solar thermal and/or district heating systems.

RISE lead the work package of sustainability assessment, conducting life cycle assessment and develop guidelines on optimizing the environmental performance and benefits of upgrading waste heat from industry.
