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.

Diesel and gasoline prices drop in early 2020, but diesel drops substantially less

Green Car Congress

Although both diesel and gasoline are made from oil, the trends in their prices do not always go in parallel. While personal driving (which uses primarily gasoline) is down greatly because of various stay-at-home mandates, commercial truck transport (which uses primarily diesel) has been substantially less affected.

Engine testing shows environmental and performance benefits of hydrotreated vegetable oil as renewable diesel fuel

Green Car Congress

Comparison of power loss and fuel consumption among BD, HVO and iso-HVO. liter diesel engine and passenger car. liter diesel engine and passenger car. On the emissions side, iso-HVO and HVO blended diesel emit less THC and CO than BD, even though iso-HVO blended diesel emits similar level of NO x and PM to blended BD.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

Perhaps surprisingly, the greenhouse gas footprint of blue hydrogen is more than 20% greater than burning natural gas or coal for heat and some 60% greater than burning diesel oil for heat, again with our default assumptions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds.
