After his PhD, he joined Shell at its Amsterdam research centre and worked as a scientist on catalysis and reactor engineering of refinery and gas processes. Since 2000 his work has increasingly focused on alternative fuels (notably hydrogen) and renewable energy. From 2010 to 2016 he was as Manager Energy Futures responsible for technology assessment of future energy technologies. He also worked closely with Shell’s Scenarios team.
