Proton Exchange Membrane- Hydrogen fuel cell electric vehicle

This type of vessels is operated by a hydrogen fuel cell. Due to limited power output, this technology is likely to be used preferably for small and medium vessels, as currently proved by the on-going demonstrations.

Different fuel-cell types exist, and their names reflect the materials used in the electrolyte membrane.

DNV GL evaluated 7 fuel-cell technologies and concluded that the following are the most promising for maritime applications (source: http://www.dnvgl.com/maritime/publications/alternative-fuel-assessment-download.html ).

According to the study from DNV-GL, Proton exchange membrane (PEM) fuel cell is considered a mature technology. Its operating temperature is 50-100 degrees Celsius and has a typical efficiency of is 50-60% and a moderate lifetime. It has medium sensitivity to impurity, thus requiring hydrogen as a fuel, and a low cost (compared to other fuel cell technologies for maritime applications).

Manufacturing compact fuel cells with high power densities is quite challenging. Thus, this technology is likely to be used preferably for small and medium vessels.

The International Maritime Organization (IMO) aims to reduce the total annual GHG emissions by at least 50 percent by 2050 compared to 2008, while pursuing efforts to eliminate them entirely.

Vertically integrated companies Nedstack, Powercell, and Ballard are among the leading marine PEMFC suppliers. Corvus Energy is another notable competitor with plans to release its first FC product using Toyota-sourced fuel cells within the next few years.

The average system size per vessel has risen to over 1MW, per the project database tracked by IDTechEx in ““Fuel Cell Boats & Ships 2023-2033: PEMFC, SOFC, Hydrogen, Ammonia, LNG“. Few large systems in inland cargo vessels, workboats, offshore support vessels (OSVs), tugs, cruise ships, and ferries currently dominate the market.

IDTechEx anticipates that the majority of orders in the midterm will utilize PEMFC technology and remain in inland and coastal sectors (due to hydrogen’s volumetric limitations). However, the market is still in its infancy, and the IDTechEx report predicts that by the end of 2022, a total of 6MW will have been delivered to vessels.
