NGVA Europe study quantifies GHG reduction of natural gas use in light- and heavy-duty vehicles compared to gasoline and diesel

Green Car Congress

NGVA Europe, the European Natural & bio Gas Vehicle Association, has published its own study about the impact on greenhouse gas (GHG) emissions from the use of natural gas as transportation fuel. For heavy-duty applications, benefits compared to diesel are of 16% for CNG and up to 15% for LNG.

Study finds renewable diesel blends deliver fuel consumption and CO2 benefits in Euro 5 engines

Green Car Congress

Researchers from Istituto Motori - CNR in Italy and Eni report in a paper in the journal Fuel that blends of hydrocracked fossil oil (HCK) and Hydrotreated Vegetable Oil (HVO) as diesel fuels deliver fuel consumption (FC) and CO 2 savings based on the NEDC cycle. Its bulk modulus and material compatibility is similar to petroleum diesel.
