Solid oxide


Technology Description

Solid Oxide Fuel Cells (SOFC) run at very high temperature (500-1000 °C).
This fuel cell has low sensitivity to impurities, thus being able to run with hydrogen, methanol, LNG and diesel. It has a high cost (compared to other fuel cell technologies for maritime applications), can have medium size and has a moderate lifetime. Typical efficiency is 60% and this can be optimised to 85% with heat recovery,

Relevance for Net Zero

Fuel cells have better energy efficiency than internal combustion maritime engines and do not emit pollutants.
Solid Oxide Fuel Cells (SOFCs) can work with several fuels and thus provide flexibility to ship operators, potentially making them an option to power oceangoing vessels.
Their limited power density is challenging for long-distance routes, making this technology more suited to short- and medium-distance vessels.
