The B-Class fuel cell will go into production in 2010. Daimler chief Dieter Zetsche believes it can be economically feasible and competitive with conventional cars. "Today we are convinced by 2014 or '15 we can offer fuel cell vehicles that compete technically and on price with conventional powertrains, in the range of 100,000-plus units a year. It's a stretch but realistic target." Mercedes won't wait for a hydrogen infrastructure. It's in discussions with such power-generation companies as Linde. "One percent of today's hydrogen production would fuel 5-million fuel cell vehicles, so it's not a totally new world."
