Long touted as the fuel of the future but not of the present, the age of hydrogen may be about to start.

Billions of dollars in federal subsidies are part of a massive industrial policy pushing the energy source. The U.S. Department of Energy is pouring $7 billion into a series of regional hydrogen production hubs to make sure it’s available for transportation and heavy industry. It also plans to subsidize the cost of hydrogen when produced with green technologies.

Automotive News’ tech and innovation reporting team identifies the challenges and opportunities for hydrogen fuel adoption in autos and adjacent industries. The industry’s vision for a zero-emission future is clear, and there are multiple paths to get there. Policymakers are ensuring that hydrogen will be one of them. See our report.
