DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Heavy-duty diesel vehicles using mixing controlled compression ignition (MCCI), the most common ignition and combustion strategies for heavy-duty diesel engines, contribute significantly to the emissions of GHG, oxides of nitrogen (NO x ), and particular matter (PM) and are subject to stringent emission standards. Skaggs et al.

Aberdeen awards ULEMCo contract for 35 hydrogen dual-fuel utility vehicle conversions

Green Car Congress

ULEMCo has been awarded a major fleet-wide contract by Aberdeen City Council (ACC) for its hydrogen dual-fuel utility vehicle conversions. ULEMCo’s H2ICED allows hydrogen to be mixed with diesel directly in a conventional engine, supplied via onboard gas tanks, in volumes that displace between 30-70% of the energy from diesel.

OptiFuel to repower Argentina’s 400 freight locomotive fleet from diesel-power to CNG and/or RNG

Green Car Congress

Traditional locomotives run on diesel fuel, emitting high levels of NO x , PM, and CO 2. OptiFuel is developing modular repower kits for diesel locomotives and new locomotives in all lengths, horsepower levels, and track gauges. For line-haul operations in the US, RNG is the only practical zero-emission diesel-alternative solution.

First conversion of a slow-speed marine diesel engine to operate on ethane as a fuel

Green Car Congress

ABS has confirmed the successful conversion of a slow-speed marine diesel engine to operate on ethane as a fuel. The 15-day long conversion followed engine performance and emissions testing at Kawasaki in Japan, to prove the principle that burning ethane in the Navigator ME-GI engines would be possible.
