The U.S. Treasury and the Internal Revenue Service recently updated rules for hydrogen production tax credits, positively impacting the energy sector and the nuclear industry. Clean hydrogen production now qualifies for tax credits of up to $3 per kilogram, encouraging companies to invest in cleaner hydrogen infrastructure. This move has particularly boosted stocks of companies like Plug Power, Constellation Energy, and Vistra. The tax credit, part of the Inflation Reduction Act signed by President Joe Biden, aims to lower the cost of producing clean hydrogen, which historically has been more expensive than conventional methods. The revised rules also allow nuclear power providers to benefit from billions of dollars in credits for hydrogen production. Constellation Energy and Vistra saw significant stock increases following this announcement. Additionally, companies focused on small modular reactors, such as Oklo and NuScale Power, experienced surges in their stock prices. Plug Power, a key player in green hydrogen, has been increasingly emphasizing its involvement in the clean energy supply chain. Despite past struggles to meet hydrogen supply demands, Plug Power recently received a $1.6 billion commitment from the U.S. Department of Energy for clean hydrogen development. The company also completed its first customer order, delivering liquid hydrogen to major retailers like Amazon, Walmart, and Home Depot. The article concludes with industry experts and executives expressing optimism about the impact of the updated tax credit rules on the clean hydrogen projects and the nuclear industry.
