Copenhagen-headquartered freight and passenger ferry operator DFDS is evaluating a system that injects methanol and hydrogen as a solution for its conventional four-stroke engines.

The FS+ system, developed by Germany-based technology developer FuelSave, injects hydrogen, oxygen and methanol mix at three precisely calibrated different locations along the air intake of a four-stroke engine.

The solution uses an onboard hydrogen synthgas generator to produce hydrogen as needed, eliminating hydrogen bunkering requirements. The Motorship featured an interview with FuelSave in May.

“We have seen the results of a trial installation, and they are very promising,” Jacob Pedersen, Head of Projects & Implementation in DFDS’ Technical Organization told The Motorship.

One of the key advantages of the FuelSave solution is that it offers significant fuel efficiencies for DFDS’s existing vessels.

“It could reduce our consumption of black fuel by 15%, with only a 3-4% increase in methanol consumption,” Pedersen said, adding that the limited space requirements of the FS+ equipment was a particular advantage for DFDS’s existing vessels.

DFDS is waiting for additional data on the performance of the system with different engine designs from various four-stroke engine manufacturers.

“We haven’t put any FuelSave equipment on our ships yet but, so long as the data is acceptable, I would expect us to begin a pilot project in Q3 2021,” Pedersen said.

The solution was far from being the only technology on Pedersen’s agenda. “We had 50 projects on our long list, and 29 projects have made the cut: we love to cooperate with companies developing promising technology.”

The innovative solution is only one part of the company’s ambitious plans to lower environmental emissions. The company is also planning to achieve fuel efficiencies through the introduction of route optimisation software on board vessels, supplanting the company’s existing fuel consumption reports.
