DL­R­magazine 171 – Awak­en­ing the sleep­ing gi­ant

Test Facility for Thermal Energy Storage in Molten Salt (TESIS)

Until now, the energy transition has largely revolved around electricity; sustainable heat has been sidelined for quite some time. However, current uncertainty over energy supply is beginning to change this. For a while now, DLR scientists have been working on this sleeping giant, conducting research into various technologies and concepts for climate-friendly heat using renewable sources, including heat pumps, thermal wind energy, energy systems analyses and the use of lime for heat storage. The cover story of issue 171 of the DLRmagazine gives an overview of the different aspects and potential of heat. We also interview Christian Sattler, Divisional Board Member for Energy and Transport, to understand whether we are facing a ‘heat problem’.

Incidentally, an entirely different issue with heat has been developing in the Arctic, a region that is warming up much faster than the rest of the world. An international research team has travelled to the North Pole to study the phenomenon of Arctic amplification and the effects that this warming could have on the rest of the planet.

It is not just human researchers who are busy at DLR. In the ARCHES project, a team of robots journeyed to one of the most inhospitable areas in Europe – Mount Etna. In this issue, you can read about why they explored the Sicilian volcano and the special skills each individual team member brought to the project.

The number of people that read the DLRmagazine regularly is growing steadily. It is distributed well beyond the specialist community – in Germany and abroad. Of course this motivates us to improve continuously. We count on your support for this: We have created an online survey for DLRmagazine readers – it only takes a few minutes to complete. Please take this opportunity to give us your feedback. You can do so until 15 January 2023 here.
