The urgent need to combat climate change has put a spotlight on the potential of green hydrogen as a clean and sustainable fuel to replace fossil fuels in critical sectors. India, as the third-largest CO2 emitter globally, is embracing green hydrogen as a means to reduce emissions and enhance energy security. Green hydrogen, generated through the electrolysis of water using renewable energy sources like solar and wind power, stands in stark contrast to grey hydrogen produced from fossil fuels, which emit significant CO2. Although the cost of green hydrogen is currently higher than grey hydrogen, there is a growing consensus on its long-term benefits for the environment and economy. The applications of green hydrogen span across various sectors, including energy storage, transportation, industrial processes, and domestic energy networks. India's National Green Hydrogen Mission, backed by substantial government funding, aims to scale up green hydrogen production significantly by 2030, driving a shift towards cleaner energy sources. The market for green hydrogen in India is projected to experience exponential growth, with ambitious targets set to meet a substantial portion of the country's hydrogen demand within the next decade. Strategic partnerships with global markets and policy measures to support green hydrogen production are key strategies in India's pursuit of energy transition and emission reduction. Leading Indian companies are spearheading the adoption of green hydrogen, with investments in technology, production facilities, and downstream products like green ammonia. Their efforts, coupled with government support and industry collaboration, are propelling India towards a greener and more sustainable energy future.
