The Digest’s 2025 Multi-Slide Guide to Decarbonization of Offroad, Rail, Marine, and Aviation Technologies

The DORMA program focuses R&D on efficient utilization of renewable fuels, hydrogen, and e-fuels to achieve deep GHG emission cuts across multiple heavy-duty sectors. Technology accomplishments include demonstrating 95% ammonia substitution in marine engines, yielding an 85% CO2 eq reduction. Future work is heavily focused on increasing R&D for Hydrogen Internal Combustion Engines (H2ICE), advancing electric and hybrid-electric powertrains for off-road vehicles, and leveraging exascale computing for Sustainable Aviation Fuel (SAF) and contrail research.
