Investors are showing increasing interest in hydrogen stocks, viewing them as an emerging opportunity with the potential for solid returns. The market for hydrogen and hydrogen-based fuels is expected to grow at around 8% annually between the current year and 2030, contributing significantly to reducing carbon emissions. Linde (LIN), a global leader in industrial gases, is highlighted for its pioneering work in hydrogen, evident through initiatives like the world's first hydrogen refueling systems for trains. With forecasted share price growth between 9-25% and a 1.3% dividend yield, investors remain positive about Linde's future prospects. On the other hand, BP, despite facing criticism for its green energy focus and recent poor performance, has expanded its hydrogen pipeline significantly, focusing on blue hydrogen production from natural gas. Air Products and Chemicals (APD) is also positioned as a reliable investment choice in the hydrogen sector, offering an 8.7% return expectation and a higher dividend yield of 2.8%. APD's status as the largest global hydrogen supplier and its substantial investments in low carbon hydrogen projects make it an attractive option for investors. While these companies show promise in the hydrogen market, BP's performance and investor sentiment highlight the challenges in balancing traditional energy investments with green energy transitions.
