Advent Technologies And Siemens Energy Collaborate On Maritime Fuel Cell Solution


  • Advent Technologies, a subsidiary of U.S. Advent Technologies Holdings, and Siemens Energy have entered a joint development agreement (JDA) to create a 500 kW high-temperature proton exchange membrane (HT-PEM) fuel cell solution for maritime use.
  • This collaboration aims to leverage Advent’s HT-PEM fuel cell modules with Siemens Energy’s electrification and automation expertise to address the power needs of large yachts initially, with plans to expand to ferries and commercial ships.

Advent Technologies and Siemens Energy have signed a joint development agreement (JDA) to develop a 500 kW high-temperature proton exchange membrane (HT-PEM) fuel cell solution tailored for maritime applications. This collaboration combines Advent’s HT-PEM fuel cell technology with Siemens Energy’s electrification and automation solutions to create an integrated solution suitable for various maritime vessels.

Objective and Market Scope

The primary objective of this collaboration is to create an integrated 500 kW HT-PEM fuel cell solution, adaptable to the diverse requirements of the maritime market, ranging from motor and giga yachts to ferries and container/commercial ships. The partners aim to develop a clean energy solution to meet the power demands of large yachts initially, with plans to expand its application to include other maritime vessels in the future.

Prototype Development and Testing

Initial prototype testing for the HT-PEM fuel cell module is scheduled to occur at Siemens Energy’s testing facility in Erlangen, Germany, in 2025. The testing phase aims to evaluate the performance and feasibility of the fuel cell module, with the first fuel cell module expected to undergo testing by 2026.

Key Features of HT-PEM Fuel Cell Technology

Advent’s HT-PEM fuel cells, incorporating Ion Pair membrane electrode assembly (MEA) technology, offer high-temperature operation between 80°C and 240°C, extending their lifespan and doubling power density compared to previous systems. These fuel cells enable the use of liquid green fuels like eMethanol, enhancing efficiency and resilience, even under challenging environmental conditions.

Previous Collaborations and Future Outlook

The agreement between Advent and Siemens Energy builds upon their prior collaborations, including the Sanlorenzo Life Ocean pilot project and the RiverCell 3 research and development project. Advent’s Chairman and CEO, Vasilis Gregoriou, highlighted the goal of positioning HT-PEM fuel cell technology as a vital component in global decarbonization efforts, particularly in achieving net-zero emissions in the maritime sector by 2050.
