New study finds gasoline stations vent up to 10x more benzene fumes than previously thought

Green Car Congress

A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

Comparison of current federal subsidy to base case assumptions showing lifetime fuel savings (HomeEve charging scenario). An EPA estimate based on the Chevy Volt’s reported efficiency is also included for comparison. In all cases, HEVs and PHEVs save gasoline over conventional vehicles. Earlier post.).

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

We have therefore developed a hydrogen combustion engine that aims to match the power and torque of current high-performance gasoline engines as a concept study. liter eight-cylinder gasoline engine—or rather, its digital data set, since we conducted the entire study virtually using engine performance simulations.

Neste files patent on gasoline fuels with high bioenergy content

Green Car Congress

Neste, currently largest producer of renewable drop-in fuels (primarily diesel) with its NEXBTL platform ( earlier post ), has filed a patent ( US20150144087 ) on a gasoline composition (and the method for making it) comprising up to 20 vol% (preferably from about 10-15 vol.%), of paraffinic bio-hydrocarbons originating from the NEXBTL process.

“Charging Station” — Is That the Location or the “Charger”?

EV Adoption

This requires simple, easy-to-understand terms without jargon, and that leverage consumer’s existing reference point of the gasoline refueling experience. In an ensuing discussion around this “charging station” reference it wasn’t clear what the author meant. 39% assumed charging station refers to the site/location and 43.2%
