The maritime sector represents about 13.5% the total greenhouse gas (GHG) emissions at EU level (Source: EEA, 2021). In order to foster decarbonization of fuels in the maritime sector, the IMO fixed a target of 80% cut of GHG emissions until 2050 and cut of 100% until 2100. The path towards decarbonization of fuels in the maritime sector will also lead to the reduction and/or abatement of pollutants like CO, NOX, SOX, PM, BC, HC that are emitted by fossil fuels combustion. The installation of a methanol reformer coupled to a HTPEM fuel cell could represent an interesting solution as auxiliary power unit of yachts and superyachts, to cover the hotel load but also to sustain slow speed cruising and maneuvering operations in ports.
Why using green methanol?
Instead of methanol the project will foster the adoption of green methanol (methanol produced by renewable sources, i.e. from agricultural and forestry residues, biogas, organic fraction of municipal solid wastes, synthesis of H2 produced from electrolytic processes and CO2 coming from carbon capture technologies).
Furthermore, methanol is easy to store and handle, it is biodegradable and does not contain sulphur. It is liquid at environmental temperature and pressure, it presents a good energy density (around 22 MJ/kg) and does not need cryogenic tanks for its storage like LNG.
