Market ramp-up ahead - Joint forces required!

Session 1-2A
Room: Skt. Hans Torv & Nørrebros Runddel, ground floor
Chair: T. Nowak, EHPA

11.30 - 12.30     High-temperature heat pumps are a key technology for sustainable process heating and a massive scaling of the market is required to exploit the potentials. This rapid development does, however, also imply challenges for different parties. End-users need to put their strategy on unmature technologies, technology suppliers need to develop technologies with a yet unclear application potential, and policies need to consider new technologies for an unknown market. This debate will highlight the challenges from different view points and elaborate on strategies to exploit the full potential by joining forces across various disiplines.
