We recently published a list of 10 Best Hydrogen Stocks to Buy According to Billionaires. In this article, we are going to take a look at where Plug Power Inc. (NASDAQ:PLUG) stands against other best hydrogen stocks to buy according to billionaires.
As the global push toward clean energy and decarbonization gains momentum, hydrogen stocks are seeing a renewed interest from institutional investors and billionaires. With recent advancements in hydrogen technology, this once speculative energy source is now looking like a solid investment opportunity in the clean-energy sector.
The World Energy Transitions Outlook 2025 highlights that annual deployment of over 1,000 GW of renewable power is needed to stay on a 1.5°C pathway. Hydrogen is expected to play a key role in the decarbonization of end uses and the flexibility of the power system. Investment needs for clean hydrogen and derivatives are projected at $1.1 billion per year to meet global transition requirements. An IEA 2025 Report noted that the global energy demand rose by 2.2% in 2024 – a faster-than-average rate. This reiterates the fact that the demand for alternate sources of energy is still on the rise.
More investors are looking for long-term growth opportunities in emerging sectors but are restricted by the ever-fluctuating interest rate expectations and evolving energy policies. Within these dynamics, policymakers and corporations are looking at hydrogen adoption more favorably. According to Grand View Research, the industry is projected to hit a staggering $317.39 billion by 2030, expanding at a healthy 9.3% CAGR.
After a challenging 2023, fraught with high interest rates and investor skepticism leading to a sector-wide decline in clean energy stocks, hydrogen stocks have made a recovery in 2024. The Global Hydrogen Index has gained 4.86% in U.S. dollar terms, signaling a comeback. The finalization of hydrogen tax credit guidelines could be seen as a key catalyst. Barron’s has noted that with the 45V tax credit offering up to $3 per kilogram for clean hydrogen, investment in the sector is getting a much-needed boost.
Compared to wind and solar energy, hydrogen has had smoother sailing due to direct government support and increasing private sector interest. In 2025, expanding industrial applications are likely to fuel hydrogen stocks. With research and technological advancements easing production and storage, costs and scalability can be massive improvements. Furthermore, the growing interest in hydrogen infrastructures in the U.S and Europe can bring in growth for the best hydrogen stocks.
Of course, the challenges remain. Despite strong momentum, hydrogen stocks are faced with strong cost competitiveness and regulatory uncertainty. Green hydrogen is still relatively expensive compared to fossil fuels, even with the declining costs. Stricter lifecycle emissions requirements for qualifying hydrogen progens under the 45V tax credit are likely to lead to an adoption slowdown. Also, geopolitical uncertainties pose additional risks within supply chains.
While not entirely free of challenges, there is no denying the rising interest in the industry. Its vast potential has attracted major investors like Bill Gates and Jeff Bezos, who are backing a startup focused on harnessing expertise from the hydrocarbon sector to capitalize on the burgeoning hydrogen market, now termed a “white gold rush” by analysts. In a growing global hydrogen economy, some of the best hydrogen stocks are in a position to create great value.
