In December 2023, the global hydrogen pipeline witnessed a substantial 35% expansion, with 1,400 projects in progress, representing potential investments of up to $570 billion by 2030. This growth outlook is promising, despite facing economic challenges. The transition from grey hydrogen to clean hydrogen is anticipated to fuel demand until 2050, creating lucrative investment opportunities in hydrogen stocks. The article also discusses the criticism by U.S. Senators Cassidy, Crapo, Risch, and Ricketts towards the Biden administration's strict 45V tax rule, which hampers U.S. hydrogen producers from qualifying for tax credits. Reforms in this policy are deemed crucial to unlock the growth potential of hydrogen stocks and facilitate renewable energy expansion for hydrogen production. Furthermore, the piece highlights three top picks in the hydrogen stocks sector: 1. Plug Power (PLUG) is identified as a strong buying opportunity, with recent developments in plant expansions and partnerships to accelerate decarbonization efforts. The company's focus on green hydrogen production positions it well to contribute significantly to emission reduction goals. 2. Air Products and Chemicals (APD) is mentioned for its significant expansion plans, including a multimillion-dollar investment in its Missouri facility and a major green hydrogen supply contract with TotalEnergies to support decarbonization initiatives in Europe. 3. Bloom Energy (BE) emerges as a top-performing hydrogen fuel cell stock, with positive projections for stock price growth in 2024. Its innovative technology, backed by partnerships with tech giants like Alphabet and Intel, underscores its potential in the clean energy market. Overall, the article advocates for investors to consider hydrogen stocks as a strategic investment choice to leverage the industry's trajectory towards clean energy solutions and emission reduction targets.
