No heat transition without solar thermal energy

The smarter E Podcast Episode 86 | März 24, 2022 | Language: German

The solar thermal industry has finally seen an upward trend in installed collector area in Germany since 2020, which has also been largely driven by solar thermal integration into heating networks. If this increase is continued, there still remains a significant gap to the forecast values that many studies assign to solar thermal on the path to achieving the goals of the Paris Climate Agreement. What is the reason for this and what is the current state of research, development and system integration of solar thermal heat supply? We talk about this with Dr. Karin Rühling from the Institute for Energy Technology at the TU Dresden.


  • 2.15: What do the latest research findings say about developments in the market?
  • 5.57: Is it worthwhile to install solar thermal collectors?
  • 10.31: What about system solutions in combination with heat pumps, pv, geothermal energy and biomass?
  • 15.17: How can solar building in existing buildings succeed?


The smarter E podcast is all about the current trends and developments in a renewable, decentralized and digital energy industry. Our moderators Tobias Bücklein and Zackes Brustik welcome and interview personalities who shape our industry and drive developments forward. A new episode is published every Thursday.
