Won’t hydrogen cars just come around and make these types of hybrids “obsolete”?
Maybe, but right now the infrastructure for hydrogen cars is not in place. The infrastructure to foster PHEVs is not totally in place either, but since light posts and outlets exist on almost every street in America, extending these out to allow for car charging will not be a major problem. Companies are starting to test charging stations that look like pay meters in urban areas, shopping malls, etc.
