[font size=3]Earlier this year, Ellen Williams, the director of ARPA-E, the U.S. Department of Energys advanced research program for alternative energy, made headlines when she told the Guardian newspaper that "We have reached some holy grails in batteries.
Despite very promising results from the 75-odd energy-storage research projects that ARPA-E funds, however, the grail of compact, low-cost energy storage remains elusive.
A number of startups are closer to producing devices that are economical, safe, compact, and energy-dense enough to store energy at a cost of less than $100 a kilowatt-hour. Energy storage at that price would have a galvanic effect, overcoming the problem of powering a 24/7 grid with renewable energy thats available only when the wind blows or the sun shines, and making electric vehicles lighter and less expensive.
But those batteries are not being commercialized at anywhere near the pace needed to hasten the shift from fossil fuels to renewables. Even Tesla CEO Elon Musk, hardly one to underplay the promise of new technology, has been forced to admit that, for now, the electric-car maker is engaged in a gradual slog of enhancements to its existing lithium-ion batteries, not a big leap forward.

This is news to most Americans, many have no idea that Toyota has perfected a hydrogen powered car. Don't believe me, ask around.
Meanwhile, in Europe

(6,436 posts)YOKOHAMA, Japan -- Nissan Motor Co. has developed a new kind of fuel cell drivetrain for cars that taps an onboard tank of ethanol instead of pressurized hydrogen, delivering a cheaper and safer ride that it says is more user friendly.
The new technology, dubbed an e-bio fuel cell, aims to combat a common hurdle to deploying traditional hydrogen fuel cell vehicles: the lack of a hydrogen fueling infrastructure. Nissans system uses bio-ethanol, derived from renewable crops such as corn or sugarcane, and that refueling infrastructure already largely exists.
