As of 2020, there was limited hydrogen infrastructure, with fewer than fifty hydrogen fueling stations for automobiles publicly available in the U.S., but more hydrogen stations are planned, particularly in California, where, as of 2019, according to "Hydrogen View", there had been over 7,500 FCEVs sold or leased. Critics doubt whether hydrogen will be efficient or cost-effective for automobiles, as compared with other zero emission technologies, and in 2019, "USA Today" stated "what is tough to dispute is that the hydrogen fuel cell dream is all but dead for the passenger vehicle market."
