Shadowy Existence - How Solar Thermal Energy Is Helping to Shape the Energy Transition

The smarter E Podcast Episode 171 | April 4, 2024 | Language: German

Electricity or heat, or perhaps both? If you have a roof, you are spoiled for choice. Although solar collectors are significantly more efficient than photovoltaic modules, they tend to lead a shadowy existence in the public eye. Yet solar thermal energy can not only heat domestic bath water, but also supply industry with process heat and feed entire heating networks.

The Solar Thermal Symposium in Bad Staffelstein has been dedicated to solar thermal energy for 33 years. How has solar thermal energy changed since then? What technical innovations are there and what contribution does it make to the energy transition? We talk about this with the symposium's technical director, Dr. Korbinian Kramer from Fraunhofer ISE in Freiburg.

Timeline:

  • 05:58 What are the advantages of solar thermal energy over photovoltaics? Why are they not used more?
  • 07:22 How and where can solar thermal play to its strengths in the context of the energy transition?
  • 20:20 An important topic at the symposium is PVT technology. What is it? What are its advantages and where is it used?
  • 14:25 What role can solar thermal energy play in heating networks and what about process heat in industry?
