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.

Argonne: longer-range BEVs may be almost as powertrain energy dense as gasoline vehicles by 2045

Green Car Congress

Despite projected improvements in battery technology, this form of energy storage is still expected to be significantly less energy dense than gasoline even by 2045. This requires assessing the efficiency of the conversion of the stored energy to useful mechanical energy to propel the vehicle. Vijayagopal et al. Vijayagopal et al.

DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Given the nature of wet waste resources that requires dedicated waste management practices to collect, store, treat, and dispose of the waste, shifting the waste resources from going through conventional waste management practices to utilization as feedstocks for energy production may represent an avoided cost of waste management and disposal.

Fraunhofer suggests e-scooters as application for its magnesium hydride paste hydrogen storage technology

Green Car Congress

POWERPASTE stores hydrogen in a chemical form at room temperature and atmospheric pressure to be then released on demand, said Dr. Marcus Vogt, research associate at Fraunhofer IFAM. This means that POWERPASTE can offers a range comparable to—or even greater than—gasoline. Source: Fraunhofer IFAM. —Marcus Vogt.

Mercedes-Benz introduces latest E 200 Natural Gas Drive and E 220 BlueTEC BlueEFFICIENCY Edition

Green Car Congress

The E200 NGD can run on either gasoline or natural gas; benefits of running the car on natural gas include a 20% reduction in CO 2 emissions compared with comparable operation using gasoline, and much lower fuel costs. liters of unleaded gasoline (NEDC combined) for every 100 kilometers (37.3 Benz gasoline engines.

By comparison, gasoline has 34 MJ/L and diesel about 38 MJ/L. But in a world that aspires to leave behind all fuels (except hydrogen or maybe ammonia) and to electrify everything, the preferred measure of stored energy density is watt-hours per liter. times as much energy by volume and at least twice as much by mass.
