Investment fund managers have gained sector insights and received due diligence advice to support asset allocation decisions. Industrial gases businesses have used my guidance to develop and grown their profits. Industrial operating companies have benefited from my expertise in decarbonisation, hydrogen, CCTUS, gas analysis instrumentation and gas cylinder / valve technologies and markets. For several years, I supported Nexant Energy & Chemicals Advisory in the DACH region. Clients ranged from major oil, gas and chemical companies, governments to investors and financial institutions. In buy-side and sell-side engagements, I advised numerous M&A transactions. As a member of the H2 View and gasworld editorial advisory boards, I advise the direction of journalistic content for these two leading international publications. I am also an expert trainer for CLASS OF H2. I chaired the e-fuels and hydrogen propulsion track at the Hydrogen Technology Expo in Bremen during Sept 2023 and in Hamburg in Oct 2024. I chaired the CO2 Utilisation Summit in Hamburg in Oct 2023 and Berlin in Sept 2024. In 2025, I chaired the Green Ammonia Summit in Düsseldorf. I am on the advisory board for the 2025 Hydrogen Tech And CCS Expo in Hamburg.
