Methanol vs Green Ammonia: the future of marine fuels

IMO 2030 targets a reduction in average carbon intensity (CO2 per tonne-mile) of at least 40pc by 2030. This is an improvement in the relative efficiency per tonne-mile from the perspective of CO2 emissions. This represents the IMO’s medium-term goal.
IMO 2050 will introduce far stricter targets, necessitating a 50pc reduction of greenhouse gas (GHG) emissions from shipping by 2050. In order to meet this more aggressive
target by 2050, zero carbon fuels will need to play a part in the fuel mix beyond 2030.
Ammonia vs methanol is going to be something that will be debated a lot when it comes to meeting IMO 2050. Ammonia and methanol have a lower energy density than conventional marine fuels. The main hurdle for ammonia will be bringing down the built up cost of green ammonia and availability.
Note that even though ammonia has an established market and infrastructure, potential additional demand from new uses such as marine fuels and power generation might require huge investments in new infrastructure, which in the short term might slow down market penetration.
That unlike the majority of other alternative marine fuels, methanol can be the solution in the short, medium, and long term. In light of the IMO’s approval, the increase in take-up by
leading shipping industry players, and methanol’s qualities as an available, easy-to-handle fuel with a sustainable production pathway–methanol is truly hard to beat as the shipping sector’s pathway fuel to the future.
