The use of low- or zero-carbon maritime fuels in the BSR hinges on the ability to handle H2-derivatives (methanol, ammonia) at the seaports. The strategy, planning & operations departments of port authorities, terminal operators, maritime fuel providers and energy suppliers lack know-how, tools and strategies to speed up the necessary preparatory works. There is a need for H2-Derivative market forecasts, techno-economic models to decide on investments, suitable bunkering equipment and berth mappings. The port transformation requires adapted port regulations including safety manuals for handling, and suitable bunkering technology. Equipment for ship-to-ship and truck-to-ship methanol bunkering needs to be defined and tested, proper public communication with port residents are required. H2Deri@BSP will increase the capacity of port authorities and helps to build stronger cooperation to jointly develop proof-of concepts for the uptake of H2 Derivatives fuels and by that demonstrates a pathway to the successful transition towards zero emission in energy supply and shipping. The project solutions are relevant for all target groups across the EU, made accessible through intensive dissemination. Target groups outside the H2Deri@BSP partnership will apply the solutions and achieve a fast transformation of green energy supply land-side and sea-side. Applying the project solutions will help reducing CO2 emissions in EU regions and mitigate the negative effects of climate change.
