Billions of dollars in hydrogen-industry subsidies from President Joe Biden’s signature climate law will come with stringent environmental safeguards, raising concerns that strict rules will stifle production of the nascent climate-friendly fuel.

Administration officials, however, said that could change when the guidelines are finalized.
