Everllence Tests Hydrogen-Fueled Ship Engine at Augsburg Facility
Everllence has successfully operated a four-stroke engine with 100% hydrogen at its Augsburg facility. This project, part of HydroPoLEn initiated in late 2023, modifies an existing dual-fuel engine to utilize pure hydrogen, improving performance density. While the technology is still in the experimental phase, it presents an alternative to fuel cells for maritime applications, with potential advantages in maintenance and integration. The maritime industry is exploring various fuel alternatives, including hydrogen, methanol, and ammonia, amid the need for reduced greenhouse gas emissions.

Everllence has operated a four-stroke engine on 100% hydrogen for the first time at its Augsburg facility as part of its HydroPoLEn project, which began in late 2023. The existing Type 35/44DF engine, originally designed for dual-fuel use, has been modified to enhance performance density under hydrogen operation.
Although this research engine is still in the testing phase and not commercially viable yet, it reflects a significant step in exploring alternative maritime propulsion technologies. In comparison to fuel cells, which are also under development, hydrogen combustion offers familiar technology for shipowners, although it has lower efficiency and may produce harmful nitrogen oxides. Everllence is also developing a large electrolyzer through its subsidiary Quest One, further integrating hydrogen production and consumption.
