How to sustainably decarbonise heating – a topic increasingly on our radar as we strive to become more energy efficient – and one of the key focus points in this episode of the Energy Transitions Podcast.

There are several new innovative technologies making an impact to decarbonise the heating space, such as deep geothermal, solar geothermal, and harnessing of waste heat. To learn more about how these technologies are making an impact and driving decarbonisation efforts, Pamela Largue speaks to Dr Andrej Jentsch, Programme Manager of the IEA Technology Collaboration Programme on District Heating and Cooling.

Jentsch, who mainly works for the AGFW, an association promoting district heating and cooling and combined heat and power, delves into why our progress (or lack thereof) is a matter of will and why we can not achieve our efficiency goals without a systems perspective and a sound measuring and analysis methodology.

“We often forget that using all the waste heat that we have, we just have to collect it, it’s even easier to get to that heat than to geothermal…while some argue waste heat is not renewable, it’s very good for the climate…” - Dr Andrej Jentsch
