Are electric cars running out of juice again?
Recent moves by Japan's two largest automakers suggest that the electric car, after more than 100 years of development and several brief revivals, still is not ready for prime time - and may never be.
In the meantime, the attention of automotive executives in Asia, Europe and North America is beginning to swing toward an unusual but promising new alternate power source: hydrogen.
The reality is that consumers continue to show little interest in electric vehicles, or EVs, which dominated U.S. streets in the first decade of the 20th century before being displaced by gasoline-powered cars.
Despite the promise of "green" transportation - and despite billions of dollars in investment, most recently by Nissan Motor Co - EVs continue to be plagued by many of the problems that eventually scuttled electrics in the 1910s and more recently in the 1990s. Those include high cost, short driving range and lack of charging stations.
The public's lack of appetite for battery-powered cars persuaded the Obama administration last week to back away from its aggressive goal to put 1 million electric cars on U.S. roads by 2015.
The tepid response to EVs also pushed Nissan's high-profile chief executive, Carlos Ghosn, perhaps the industry's most outspoken proponent of battery cars, to announce in December a major strategic shift toward more mainstream gasoline-electric hybrids, which overcome many of the shortcomings of pure EVs.
The move was widely seen as a tacit acknowledgement by Ghosn that his all-or-nothing, multibillion-dollar bet on EVs is falling far short of his ambition to sell hundreds of thousands of battery-powered Nissan Leafs.
Instead, Nissan plans to follow rival Toyota Motor Co , the world's largest purveyor of hybrids, which now is poised to leapfrog pure EVs altogether to pursue what might be the next big green-tech breakthrough: pollution- and petroleum-free fuel-cell cars that convert hydrogen to electricity.
Vice Chairman Takeshi Uchiyamada, the "father of the Prius" who helped put hybrids on the map, said he believes fuel-cell vehicles hold far more promise than battery electric cars.
"Because of its shortcomings - driving range, cost and recharging time - the electric vehicle is not a viable replacement for most conventional cars," said Uchiyamada. "We need something entirely new."
TOYOTA'S LONG LEAD
In the race to identify the Next Big Thing in automotive technology, the stakes are enormous.
For example, Nissan, with French partner Renault, has committed $5 billion for development and manufacture of EVs and batteries
