Strategic Biofuels successfully tests carbon capture and storage for renewable diesel plant

Green Car Congress

LGF is the first renewable diesel fuel project to achieve this milestone. Carbon capture and permanent geologic sequestration is no longer a hypothetical scenario for Louisiana Green Fuels—successful completion of the test well is a major milestone that’s not been achieved by any other renewable diesel project.

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.

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.

Bombardier (now Alstom) to convert AGC hybrid trains to full battery power

Green Car Congress

The effort is part of France’s strategy to eventually phase diesel power out of its national rail fleet. The idea is to convert dual-mode (catenary and diesel-powered) high capacity self-propelled trains to dual-mode battery-powered AGCs. Technicians will remove the trains’ diesel packs and replace them with four battery units each.
