Hydrogen fuel cells are controversial—several automakers, including Daimler, Honda, GM and Volkswagen, have abandoned the technology, while Toyota continues to pursue it.
Hydrogen opponents cite its inefficiency relative to batteries, and question the wisdom of building a complex and costly new infrastructure.
On the other hand, many believe that hydrogen may have a role to play in industrial processes, and for powering heavy-duty vehicles, including ocean-going ships and aircraft.
Many articles in the mainstream media, however, ignore the controversy—for example, a recent article in the New York Times depicts hydrogen fuel cells as a proven technology that only needs to be scaled up to be a viable alternative to internal combustion. ABC News also recently ran a rapturous rhapsody hyping hydrogen as the fuel of the future - Link
