Shares of fuel cell technology company Plug Power surged 26.7% following the announcement of changes to a GOP tax bill by the U.S. Senate. The bill extends hydrogen tax credits, giving a boost to hydrogen producers like Plug Power. This extension, moving the expiration date to January 1, 2028, provides a two-year runway for scaling operations and enhancing cost-competitiveness against fossil fuels. For Plug Power, which has been investing heavily in hydrogen production but facing profitability challenges, this policy change is a significant positive. The lowered cost of producing clean hydrogen is expected to drive demand from industrial customers and improve the company's path to profitability. Despite a downtrend over the past year, investors are optimistic about Plug Power's future, citing strong Q2 2025 revenue guidance and growth potential in the enterprise software sector.
