Non-Executive Director (Non-Exec) with energy and industrial process design and development expertise is required for our client Cleen Sun, an ESG start up in the clean energy sector, based in Northwood, Middlesex. 

The business was established to develop a zero emissions clean energy system with a patented, innovative combustor assembly - Cleen Sun - which when fitted to existing process and power applications can increase net energy efficiency by up to 30%.

Cleen Sun is capable of operating across a variety of gaseous feedstocks, which while producing power, is effectively an energy efficiency tool, by virtue of the fact it requires no additional raw fuel to produce electricity.  As such, on an incremental generation basis, it is effectively a zero-carbon technology.
