Study Shows Higher Compression Ratios Boost the Performance of Both Hydrous Ethanol and E22 Blend

Green Car Congress

This product is referred to as hydrous ethanol—approximately 93% ethanol and 7% water. Performance parameters evaluated were torque, brake mean effective pressure (BMEP), power, specific fuel consumption (SFC), thermal efficiency, exhaust gas temperature and volumetric efficiency.

Mærsk, Wallenius Wilhelmsen, BMW Group and others partner to explore blend of lignin and ethanol for sustainable shipping fuel

Green Car Congress

Hybrid technology refers to the production of fuels by both biochemical (fermentation of carbohydrates) and thermochemical (thermal upgrading of lignin) processes. They also observed that Progression Industry in the Netherlands has been collaborating with Mærsk to develop a lignin-based marine fuel—CyclOx—since 2012.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

pre- and post- decarbonization of the electric power sector—to which he referred as pre-CCS and post-CCS, respectively (although decarbonization was not necessarily via CCS—carbon capture and storage).) Direct capture of CO 2 from air, or from an exhaust stream vented to the atmosphere, represents negative emissions.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The distilleries were referred to as “stills” and the alcohol became known during the Prohibition period as “moonshine.” The result is more efficient combustion, cooler running engines, lower exhaust temperatures, and increased longevity of engine life. During the early 1900s, a distillery was a standard piece of farm equipment.
