The Biden administration unveiled final rules under the Inflation Reduction Act, providing tax credits for clean hydrogen energy. This move has positively impacted industry players like Nikola and Plug Power, with shares rising significantly. The Treasury Department's rules extend tax credits to certain nuclear power plants to encourage low carbon emission hydrogen production. The credits, offering $3 per kilogram of hydrogen, aim to boost hydrogen utilization in emission-heavy sectors. Nikola, known for manufacturing electric and hydrogen-powered trucks, experienced a rise in shares, especially due to its hydrogen-focused sub-brand HYLA. The company's fuel cell electric vehicles produce zero carbon emissions, aligning with green hydrogen goals. Biden's senior climate adviser highlighted the rules' significance in making the US a global leader in green hydrogen. The regulations aim to support hydrogen projects and provide certainty for producers. Despite the positive outlook, uncertainties exist regarding the IRA's future under the incoming administration. Additionally, Nikola's founder, Trevor Milton, addressed concerns about the company's performance, signaling challenges ahead.
