The Maritime Industry Decarbonisation Council (MIDC) held a brainstorm session (engineers only :-)) hosted by the Belgian dreding company DEME. The main subjects of discussion were electrification, hybridization and alternative fuels for shippping. There was an intensive and fruitful debate on the pros and cons of alternative fuels (hydrogen, methanol, ammonia, …) for shipping the energy-content of the fuels being considered one of the main barriers at this moment. In order to feed the discussions presentations were given by CMB, Meyer Werft and DEME.
