Green hydrogen is fast becoming the next big theme in the global energy transition. Governments and companies are now racing to build capacity as industries look for cleaner alternatives to fossil fuels.
Unlike conventional hydrogen, green hydrogen is produced by splitting water into hydrogen and oxygen using electrolysers powered by renewable energy sources such as solar and wind. The fuel produces no carbon emissions and can be stored for later use in electricity generation, heat, and transportation.
Its biggest opportunity lies in sectors that are difficult to decarbonise. This includes steel, fertilisers, specialty chemicals, heavy manufacturing, and mobility. The opportunity is massive.
According to Waaree Energies, the global green hydrogen market was valued at nearly US$ 12 billion (bn) in 2025 and is expected to reach US$ 231 bn by 2035, at a 34% CAGR.
India is also pushing aggressively to build a leadership position in this space. Under the National Green Hydrogen Mission, the government aims to produce at least 5 million metric tonnes (MT) of green hydrogen annually by 2030.
This could create demand for nearly 40-60 gigawatt (GW) of electrolyser capacity. The mission has received an allocation of Rs 197.4 bn and is expected to attract more than Rs 8 trillion (tn) in investments by 2030.
Against this backdrop, we examine 5 stocks currently undertaking capacity expansion to capitalise on long-term, structural opportunities in the green hydrogen sector.
INOX India serves industries shifting towards cleaner energy solutions, with green hydrogen emerging as a key growth area. The company leverages its decades of expertise in cryogenic storage, advanced modeling techniques, and hydrogen handling to support the growing hydrogen economy.
Liquid hydrogen's superior energy density enables long-distance transport. This positions INOX's specialised cryogenic technology as a vital facilitator for global hydrogen trade.
INOX India offers an end-to-end solution for the storage and transportation of liquid hydrogen. It manufactures tanks in sizes ranging from small to large, depending on customer requirements.
The company has a long-standing relationship with ISRO, having initially designed and supplied 15 m3 Liquid Hydrogen tanks to ISRO's launch facility in 2010. Recently, ISRO awarded a contract to the company for a much larger liquid hydrogen storage tank with a capacity of 86 Kilolitres (KL).
INOX has also supplied hydrogen storage tanks for mobility applications in the South American market. The company has successfully executed key international hydrogen projects. Recently, INOX India commissioned its first installation of Liquid Hydrogen tanks in South Korea.
Furthermore, INOX received an order for a 2 KL liquid hydrogen tank from a customer in New Zealand, marking a significant milestone in the expansion of its hydrogen portfolio.
In a major strategic expansion, INOX signed an MOU with Fabrum, a global leader in small to medium-scale hydrogen production, liquefaction, and storage solutions.
Under this agreement, Fabrum will utilise INOX's liquid hydrogen storage vessels for its projects in the Asia-Pacific region. In return, INOX will sell Fabrum's hydrogen liquefiers and boil-off gas management systems to its customers in the same region.
This partnership aims to utilise each other's strengths to drive success in the liquid hydrogen industry. INOX estimates that global annual hydrogen demand will exceed 6 MT by 2030. This is expected to create significant opportunities for cryogenic equipment suppliers.
Consequently, the demand for cryogenic tanks, trailers, and terminals for storing green hydrogen is expected to persist. To this end, it plans to address the needs of port-based hydrogen hubs.
The shift from grey to green hydrogen for ammonia production is also expected to increase overall demand for INOX India's storage and transportation solutions.
