We want a future where the energy we use does not destroy our planet 


Our vision is for an efficient and sustainable global power sector free from SF6

After 10 years working in R&D for the power industry, Manjunath Ramesh became increasingly concerned about the long-term environmental impact of SF6 - a gas with a global warming potential 23,500 times higher than CO2 found in most medium voltage switchgear. He used his experience to develop an innovative new switchgear that replaces the SF6 gas with clean, breathable air without compromising performance.


Brought together by their shared commitment to the environment - and a great product idea - Manjunath, Nikolaus and Fabian founded nuventura in July 2017.  The company has since successfully developed, built and tested the new technology and secured licensing and pilot partners for operation. Nuventura operates out of Berlin and is part of the renowned Climate KIC Accelerator. The company has also secured financing from industry experts, impact investors and private investors.

Nuventura was founded by a switchgear expert and experienced entrepreneurs

our motivation

“Anything else you’re interested in is not going to happen if you can’t breathe the air and drink the water. Don’t sit this one out. Do something. You are by accident of fate alive at an absolutely critical moment in the history of our planet.”
