David Ryan has already had a “significant” impact at the waste gasification specialist, despite only joining the board last month.
He will take up his new role immediately, PowerHouse said.
“David’s impact is already being felt at PowerHouse. In the past six weeks we have made significant improvements to our commercial engineering processes,” said executive chairman Keith Allaun.
“His experience delivering multiple projects concurrently, with world-class teams, creating outstanding results, provides us with tremendous confidence in our ability to bring the Distributed Modular Gasification (DMG) process to market in the near term.”
Before joining PowerHouse, Ryan was the former chief executive and managing director of Thyssenkrupp Industrial Solutions’ oil & gas business unit for the UK.
He has over 30 years of experience in the engineering, business development and project management spaces, PowerHouse said.
