Centre releases draft roadmap for R&D for green hydrogen manufacturing, storage
New Delhi: The union ministry of new and renewable energy on Wednesday released the draft roadmap for research and development of green hydrogen manufacturing and storage. As per the draft roadmap, the plans to develop efficient, safe, and cost-effective hydrogen storage methods that enable high-density storage, reduce leakage, and allow for easy and quick refueling.
The ministry aims to demonstrate distributed aboveground storage solutions available at a capital cost lower than ₹30,000 per kg by 2030 along with demonstrating large-scale underground storage at a capital cost less than ₹3000 per kg by 2030. The roadmap outlined examples of storage facilities globally.
It mentioned that hydrogen storage in salt caverns is already used in the US, Britain, and Germany. The walls of a salt cavern are stable and impervious to gas over the lifespan of the storage facility.
It noted that hydrogen can be generated from diverse resources, which include fossil fuel resources such as coal, natural gas, and lignite, and renewable resources such as biomass and water splitting using solar, wind, hydroelectric, and geothermal energy. Fossil fuels-derived hydrogen production includes coal gasification, along with hydrocarbon reforming and pyrolysis.
Renewable resources-based hydrogen production includes biomass process and water splitting using renewable energy. It said that electrolysis, with high capital costs and dependency on electric costs, has made it the most expensive method of producing hydrogen. Noting that technology advancement to build large capacity and improve the efficiency of electrolysers is a major big challenge, the draft roadmap said that by 2030, government aims a steep reduction in electrolyser capital and
