So far, scientists have struggled to find batteries for electric cars that match the huge amounts of energy stored in a gallon of gasoline or diesel. Fossil fuels may not be the cleanest way of powering us between two points on a map, but there''s little doubt they offer convenience.

The Net-Zero Neighborhood is based on local generation using renewables; distributed energy storage in proportion to the population; electric transportation as an integral part of energy storage; energy becoming a consumer commodity that is bought and sold in a local marketplace; and a new jobs base in the form of local energy service providers.

The performance of this new generation of powertrains will reflect significant advances in battery, electric motor and gasoline engine technologies. The next Prius will also feature electric motors that will be smaller in size. We have also heard from owners that they would like a more convenient charging operation.

The second round was focused specifically on three areas of technology representing new approaches for advanced microbial biofuels (electrofuels); much higher capacity and less expensive batteries for electric vehicles; and carbon capture. Electrofuels: Biofuels from Electricity. The grants will go to projects in 17 states.

The US Department of Energy (DOE) released the EV Everywhere Grand Challenge Blueprint , which describes plug-in vehicle (PEV) technology and deployment barriers, and provides an outline for DOE’s technical and deployment goals for electric vehicles to 2022. Reducing the cost of electric drive systems from $30/kW to $8/kW.

The transition to Li-air batteries (if successful) should be viewed in terms of a similar development cycle. The energy density of gasoline is approximately 13,000 Wh/kg. With a current average tank-to-wheel efficiency of 12.6%, the usable energy density of gasoline in an automotive application is about 1,700 Wh/kg.
