Green Hydrogen for a Sustainable Future: Prospects and Challenges for Energy-Based Applications in Major Indian States by 2030

Abstract

India is a country with a rapidly growing demand for energy. Currently, most of the country's energy demand is met by fossil fuels which are hindering our environment by contributing to greenhouse gas emissions and climate change. Green hydrogen produced from renewable energy sources is clean and free from the pollution which can reduce our country's dependency on fossil fuels. Building a green hydrogen community in India can help the country to transit into sustainable development and achieve net zero emissions. Our review shows that green hydrogen can be produced in India according to the geography of the different regions rich in renewable energy resources such as solar and wind power. Many states in India have high solar energy prospectus, high wind speeds and existing infrastructure and supply chain logistics that can be used for the production and distribution of green hydrogen. States such as Gujarat, Andhra Pradesh and Tamil Nadu have been identified by the Indian government as "renewable energy clusters" and aim to support the development of green hydrogen projects. Additionally, the Indian coastal area's seawater can be used as a water source for electrolysis. These coasts are windy and suitable for wind power generation and have access to excellent ports and transport infrastructure to transport green hydrogen. Overall, India has unlimited potential for green hydrogen production due to its abundant renewable energy sources and favourable geographical conditions. India can use this potential to become a major player in the green hydrogen market with the right political and regulatory framework.
