HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

As a result, shipbuilders and operators around the world are seeking environmentally friendly alternatives to conventional ship engines powered by fuel oil or diesel. The hydrogen molecules escape through the extremely fine pores of the membrane, while the larger carbon dioxide gas molecules are retained.

Study finds urban waste heat affects temperatures across thousands of miles, warming some areas and cooling others

Green Car Congress

The extra waste heat generated from buildings, cars, and other sources in major Northern Hemisphere urban areas causes winter warming across large areas of northern North American and northern Asia. At the same time, the changes to atmospheric circulation caused by the waste heat cool areas of Europe by as much as 1 degree C (1.8

New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. PAHs are highly volatile, meaning they escape into the air much more than many people think.

Study finds diesel derived by pyrolysis of plastic grocery bags suitable for blending with petroleum diesel

Green Car Congress

Gross product yield from the pyrolysis was 74% crude oil fraction, 17% solid residue; and 6% gases. The oil fraction broke down into 17-23% gasoline-range product; 35-42% diesel #1; 19-25% diesel #2; and 14-24% vacuum gas oil. Previous studies have used pyrolysis to convert plastic bags into crude oil. Brajendra K.

Fuel cells are also sensitive to oil admixtures. The electric compressor used to compress the supply air flow must therefore be oil-free. This also applies to the shaft bearing, as even small quantities of oil can cause irreversible damage. Compressor. Water separators. Exhaust pathway.
