Route to zero emission shipping: hydrogen, ammonia or methanol?
Route to zero emission shipping: hydrogen, ammonia or methanol?
To achieve climate change targets, new ship orders should be capable of delivering zero emission propulsion from 2025. The pathway towards this is unclear and requires significant investment. This study analyses the engineering considerations of the storage of alternative fuels on board large scale international vessels, with a particular focus on ammonia, hydrogen and methanol. Analysis of raw shipping data shows the maximum expected propulsion demand per voyage was 9270 MWh. The volume and mass requirements for alternative fuels to deliver this are projected and compared
to three further methods for estimating fuel storage considering: storage infrastructure; desired design range; both. This shows that a reduction of fuel storage quantities to closer to actual expected usage results in more realistic storage requirements. Also, hydrogen has a perceived low volumetric energy density, however the calculated volume required (6500 m3
for liquid storage) is not sufficiently high to be considered inviable.

Abstract
To achieve climate change targets, new ship orders should be capable of delivering zero emission propulsion from 2025. The pathway towards this is unclear and requires significant investment. This study analyses the engineering considerations of the storage of alternative fuels on board large scale international vessels, with a particular focus on ammonia, hydrogen and methanol. Analysis of raw shipping data shows the maximum expected propulsion demand per voyage was 9270 MWh. The volume and mass requirements for alternative fuels to deliver this are projected and compared
to three further methods for estimating fuel storage considering: storage infrastructure; desired design range; both. This shows that a reduction of fuel storage quantities to closer to actual expected usage results in more realistic storage requirements. Also, hydrogen has a perceived low volumetric energy density, however the calculated volume required (6500 m3
for liquid storage) is not sufficiently high to be considered inviable.
