Dissemination
Task 5 summarizes the various dissemination activities related to Project 65 about heat pumps in a circular economy.
65Project 65 collects, develops, and communicates valuable information related to heat pumps in a circular economy. This page provides an overview of the latest communication activities related to the project. The dissemination activities include reports, presentations, workshops, contributions at conferences and articles in magazines.
Task reports
- Task 1: Definitions and delimitation
- Task 2: State-of-the-art
- Task 3: Evaluation of potential
- Task 4: Guideline development
Workshops and selected presentations
Deep dives
As part of IEA HPT Project 65, a series of Deep Dives has been organised to explore selected topics related to heat-pump circularity. Typically held as one- to two-hour online webinars, the sessions feature invited speakers and are open to all interested participants.
