In a promising partnership, Achates Power, known for its innovative designs of opposed-piston, two-stroke compression ignition engines, has teamed up with scientists from the US Department of Energy’s (DOE) Argonne National Laboratory.
Together, they are spearheading the development of a hydrogen-powered engine customized to meet the needs of long-haul commercial vehicles.
The team of researchers showcased a demonstration in this regard, proving that the opposed-piston engine can effectively utilize compression ignition with hydrogen fuel.
“Hydrogen may be the best fuel for truly sustainable long-haul transportation. Argonne’s successful demonstration with carbon-free hydrogen combustion will be an important step towards decarbonizing the mid-duty, heavy-duty freight sector,” said Essam El-Hannouny, a principal engineer at Argonne, in a statement.
During World War II, the opposed-piston engine, invented over a century ago, experienced its prime, propelling submarines and aircraft carriers with remarkable fuel efficiency. However, its widespread adoption was hindered by increasingly stringent emissions regulations.
In recent years, advancements in technology and engineering have revitalized interest in the opposed-piston engine. Scientists are investigating its viability within a zero-carbon transportation framework, underscoring its potential to contribute significantly to sustainable mobility solutions.
Compared to traditional engines, the advanced opposed-piston engine boasts several advantages for hydrogen combustion. One key benefit lies in its streamlined design, facilitated by Achates Power’s pioneering piston architecture.
