What’s it all about?

So much of our attention is taken up by what is seen. Solar panels and wind turbines are the poster boys and girls of the clean energy revolution, but huge impacts can be made with far less visible technologies. That’s what I discuss with Berlin based start-up Nuventura, and their Co-Founder Fabian Lemke.

About our guest

Dr. Fabian Lemke is a co-founder and managing director at nuventura. Together with nuventura, Fabian is working on eliminating SF6 – the most potent greenhouse gas – from the electricity grid. Their innovative switchgear technology simply replaces SF6 with dry air, which not only leads to environmental benefits, but also enables significant performance advantages.

A switchgear is an absolutely essential component of an electricity grid. It controls and distributes electrical power flow in the electricity grid network. Existing gas insulated switchgear (GIS) predominantly use sulphur hexafluoride (SF6) – the most potent greenhouse gas in existence – as an electrically insulating medium and often also as a breaking medium. The gas is 23,500 times stronger than CO2 in terms of its global warming potential (1). It also has an extremely long lifetime of 3,200 years (2). Our aim is to eliminate SF6 from the electrical grid while improving the switchgear ‘s performance.

Prior to nuventura, Fabian worked for 5 years in the energy sector for McKinsey and 3 years as a founder and CEO of Sanubi. He holds an engineering degree in Reactor Technology from the RWTH Aachen University and a PhD in Engineering from the Karlsruhe Institute of Technology. Fabian is a proud father of two little girls.
