Indian renewable energy firms are making strides in the green hydrogen sector, with companies like Hero Future Energies, Adani New Industries, Renew, and Avaada Group expanding their initiatives domestically and overseas. Hero Future Energies is partnering with Ohmium International to develop green hydrogen plants in the UK and Europe. Adani New Industries is exploring markets in Europe, Japan, and South Korea for green hydrogen projects. Renew has signed an agreement with Egypt for a green hydrogen plant while also working on projects in various Indian states. Avaada Group is planning significant capacity for green fuels and engaging with global partners. Challenges exist, with green hydrogen currently priced higher than grey hydrogen, but industry experts anticipate cost reductions with advancements in technology and economies of scale. The sector's growth is largely attributed to government support, reflecting India's commitment to sustainable energy. Despite gradual progress, the Indian firms' expansion into green hydrogen production on a global scale signifies a pivotal move towards positioning India as a key player in the worldwide shift towards green energy.
