Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass. Energy sorghum falls somewhere in between.

PNNL study finds that PHEVs and BEVs could serve as feasible resource to offset grid imbalances caused by integration of large amounts of intermittent wind generation

Green Car Congress

The report examined grid conditions in the Northwest Power Pool, which covers Idaho, Montana, Nevada, Oregon, Utah, Washington and Wyoming; many of them home to abundant wind resources and wind energy projects. trafficIf about 13% of the existing light-duty vehicle stock (about 2.1 GW could be provided by the electric vehicles.

U Delaware team develops prototype efficient direct ammonia fuel cell for transportation

Green Car Congress

With recent and projected cost declines in wind, solar, and lithium-ion batteries, electrification using batteries has become a viable option for applications compatible with the inherent range limitations and recharging time. However, the scale of biofuels is limited by their environmental footprint, considering the land and water usage.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Their results showed that in comparison with gasoline mode, CO emitted in methanol mode decreased 11.2%.

Hondas F1 KERS motor: 60 kW, 21,000 RPM, >7 kg

Green Car Congress

Given the light weight (minimum 620 kg/1,367 pounds) and compact design of Formula One cars, Honda calculated that the motor would have to be no more than 100 mm (4 inches) in diameter, 200 mm in length, and produce approximately 8 kilowatts (kW) per kilogram (almost 5 hp per pound) of motor weight. kW per kilogram. Rotor Design.
