On the first day of stock market trading in 2025, Plug Power's stock surged by 9.9%, driven by the anticipation of new guidance from the U.S. Treasury Department on tax credits for hydrogen production under the 2022 Inflation Reduction Act. This guidance will focus on allowing hydrogen producers, like Plug Power, to claim tax credits for using nuclear power in hydrogen production. The rules will determine if companies can claim credits for hydrogen produced using existing nuclear plants and the value of these credits, potentially ranging from $0.60 to $3 per kilogram of liquid hydrogen. This decision is crucial for companies like Plug Power as it will impact the commercial viability of investing in hydrogen production. Investors buying Plug stock are essentially betting on the Treasury Department's decision being favorable to the company, with the hope that credits will be available for hydrogen produced with nuclear power and substantial enough to ensure profitability. The outcome of this decision could significantly affect Plug Power's future, making it a pivotal moment for the company and its investors.
