Unlocking the Future: Discover the Innovative Technology Pathways Paving the Way to Fuel Cells

This week, Ed Schwarz from Siemens talked about how an electric distribution “backbone” can help ferry operators. They can add more batteries, switch fuels, or even go completely emission-free with fuel cells. This flexibility is key for a greener future.

Several recent developments show that the maritime industry is moving in this direction. Lithuania’s first green hydrogen and electricity-powered ship was launched by the Klaipėda State Seaport Authority. This tanker will help manage waste from incoming vessels when it starts operating later this year. It will be powered by two electric motors, backed by 2,000kWh batteries and a hydrogen fuel cell.

In another exciting development, Van Oord showed off its all-electric crane vessel, Christiaan P, marking a first in the dredging sector. During its pilot project, the vessel used two DENS Powerhub mobile battery systems, each with 870kWh of capacity. It also features a Nexus fuel cell and a hydrogen storage container to keep the batteries charged, even when shore power isn’t available.

Additionally, sea trials are starting this month for a hydrogen-powered rigid inflatable boat from New Zealand companies Fabrum and King Watercraft. This boat carries 18kg of hydrogen gas, which powers a fuel cell. The fuel cell then charges a battery bank that runs the two electric stern propulsors.

However, using fuel cells for larger cargo ships is a different challenge. A report by the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping suggests that fuel cells won’t replace traditional internal combustion engines in ocean-going vessels anytime soon. The high costs and required changes to engine room designs and crew training make this switch complicated.

Instead of replacing internal combustion engines, the industry may see a mix of both technologies for now. Ship owners might combine fuel cells with traditional engines, allowing them to benefit from the environmental advantages of fuel cells while gradually increasing their investments as the technology becomes more affordable.

Market research from December 2024 predicts strong growth for fuel cells in the maritime sector, fueled by advancements in technology, regulatory support, and the push for sustainability. By integrating renewable energy sources with fuel cell systems, efficiency and adoption will rise, further enhancing the potential for market growth.

As the maritime industry prioritizes sustainability, fuel cells are likely to play a vital role in the future of greener shipping.
