Carmakers like Toyota have long touted the eco-friendly
virtues of zero-emission hydrogen fuel-cell vehicles, but commercialization was
hindered by the high cost of critical materials and infrastructure. Now, Toyota
has cut costs by 90 percent and German industrial gases and engineering company
Linde AG will start small-series production of hydrogen fueling stations. Some
of the stations are slated to open in California as Toyota debuts its
Highlander hydrogen fuel-cell electric vehicle (FCEV) in 2015.
