Advent Technologies, a wholly owned subsidiary of a US-based developer of fuel cell systems, Advent Technologies Holdings, has signed a joint development agreement with Siemens Energy to develop an integrated 500 kW high-temperature proton exchange membrane (HT-PEM) fuel cell solution for maritime applications.
The agreement helps combine Advent's HT-PEM fuel cell 50 kW modules, which utilize an ion-pair membrane electrode assembly (MEA) technology, with Siemens Energy's electrification and automation solutions for hybrid and electric vessels. It will further evaluate and scale the system down or up to meet market requirements, from motor and giga yachts to ferries and container/commercial ships.
The initial prototype testing for the HT-PEM fuel cell module is expected to occur at Siemens Energy's testing facility in Erlangen, Germany, in 2025, with the testing of the first fuel cell module scheduled for completion in 2026.
The HT-PEM fuel cells offer high-temperature operation between 80°C and 240°C, helping extend their lifespan by at least threefold and double the power density compared to earlier Advent systems. Additionally, Advent’s HT-PEM fuel cell technology enables the use of e-methanol, enhancing efficiency by utilizing both heat and electricity, resulting in high resiliency.
The fuel cells function with impure hydrogen, impure air intake, and extreme ambient temperature and humidity conditions, making them an ideal choice for the maritime industry.
Currently, Advent is engaging with customers in the maritime industry and expects to sign commercial term sheets in the future to pursue upcoming Requests for Proposals (RFPs).
“After two years of intensive collaboration, we stand prepared for the next stage, with the goal of positioning HT-PEM fuel cell technology as a pivotal element in global decarbonization initiatives, working towards achieving net-zero emissions in the maritime sector by 2050,” said Advent’s Chairman and CEO, Dr. Vasilis Gregoriou.
