BRUSSELS -- DaimlerChrysler's first hydrogen-powered car using fuel cell technology will be on sale in 2012, a company executive said Wednesday.
DaimlerChrysler has sent 60 Mercedes-Benz A-class cars to Japan, Germany, Singapore and the United States for tests. Many car companies are developing hydrogen-powered cars to help wean the globe off diminishing oil supplies.
The Mercedes car uses fuel cell technology where electricity is generated through the chemical reaction between hydrogen and air, emitting only water vapor.
Commercialization will start in 2012, Herbert Kohler, vice president of the body and powertrain research unit at DaimlerChrysler told reporters in Brussels, on the margins of a hydrogen car technology exhibition.
But there are still technical obstacles to overcome such as extending fuel cell reliability and durability; ensuring that they start at subfreezing temperatures; reducing costs; and storing enough hydrogen in a small enough space to be workable.
The car industry is also waiting for the introduction of hydrogen filling stations.
Shell Hydrogen CEO Jeremy Bentham said once consumers demanded hydrogen filling stations, energy companies would meet it.
"We see that these vehicles have the potential to be attractive to consumers," he told reporters. "Our job is to make sure we are prepared for that business."
Hydrogen is already produced in refineries for industrial purposes and the energy industry needs to build the infrastructure to sell it to consumers, said Bentham.
He said Europe would need 50 million tons of hydrogen a year to power cars.
Shell Hydrogen is a division of Royal Dutch/Shell.
