The U.S. Treasury and IRS recently finalized new rules on clean hydrogen production tax credits, impacting various energy stocks positively. The rules, part of the Inflation Reduction Act signed by President Joe Biden, offer a tax credit of up to $3 per kilogram for clean hydrogen production. This move has provided much-needed clarity for companies in the energy sector, encouraging investments in hydrogen projects. Companies like Plug Power and Constellation Energy experienced stock price increases, with a specific focus on green hydrogen infrastructure. Plug Power, known for its green hydrogen supply chain activities, also secured a significant loan from the U.S. Department of Energy for clean hydrogen development. Additionally, nuclear power providers, including Constellation Energy and Vistra, stand to benefit from the revised rules, allowing them to qualify for billions of dollars worth of credits for hydrogen production. The update has also boosted small modular reactor companies like Oklo and NuScale Power. Overall, the new regulations aim to drive the production of clean hydrogen from renewable sources, potentially reducing production costs and expanding the clean energy sector in the U.S.
