Hydrogen is gaining traction as a crucial element in the energy transition towards a low-carbon economy. While the sector has experienced challenges in the past, the Morningstar Global Hydrogen Index shows a recent uptrend, indicating growing investor interest. Industrial gas companies are identified as major beneficiaries of the hydrogen boom, with opportunities in production, storage, and distribution. The industry is evolving towards blue and green hydrogen, offering long-term growth prospects. Despite the slow uptake by policymakers, the International Energy Agency projects a significant increase in global hydrogen demand by 2050. Investment opportunities are emerging for long-term investors, particularly in industrial gas firms like Air Liquide, Air Products & Chemicals, and Linde, which are well-positioned to leverage the shift towards hydrogen. While the market is still nascent and stock valuations are high, the outlook for blue hydrogen remains strong, and industrial gas firms are expected to capitalize on green hydrogen opportunities in the future.
