The production of green hydrogen is experiencing rapid growth, surpassing previous conservative estimates. Green hydrogen, produced by renewable energy with zero CO2 emissions, is expected to represent 27% of total hydrogen production by 2030 and 55% by 2035. ABI Research anticipates that the market for green hydrogen will expand from US$10 billion today to US$180 billion by 2035, displacing grey hydrogen as the primary market driver. Heavy industries such as petrochemical refineries and ammonia producers are investing in low-emission hydrogen to decarbonize, cut operational costs, and benefit from green premiums. The impending net-zero regulations, particularly in Europe, China, and India, are driving the scaling of production to meet emission reduction targets. China, a significant player in global hydrogen production, is expected to lead in green hydrogen output growth, aligning with its ambitious climate goals. These developments indicate a clear shift towards green hydrogen as the fuel of the future, particularly in industries like petrochemicals, chemicals, steel, shipping, and aviation. Key companies in the green hydrogen and electrolyser production sector to watch include Adani Energy, Linde, ITM Power, Sinopec, and Plug Power. The optimistic outlook for green hydrogen underscores its potential to revolutionize the energy landscape and decarbonize hard-to-abate sectors.
