Making the leap.
Achieving breakthroughs in hydrogen imports
Bart van der Meer
Chairman of H2A
Focussing on the energy Transition and Evos’ future. Bart has a strong focus on Green Hydrogen delivered on various vectors like Ammonia and LOHC. Besides Hydrogen, he also focuses on synthetic fuels (like eSAF) and bioFuels.
Bart has always had a strong and clear focus on innovation and new technologies and is broadening Evos business offers from liquids (molecule) storage to also electron (Green energies) in a broader view. His background in the storage and handling business of liquid energy carriers in multiple jobs in various port areas in the Netherlands allows him to find the new opportunities and possibilities. Using existing (port)infrastructure and re-utilization of Evos’ assets is a key driver to initiate steps in the Energy transition without having to build from scratch. Bart has worked for Evos for 3 years but has been in the industry for more than 25 years.
