Visakhapatnam: NTPC is setting up a groundbreaking green hydrogen plant at its Simhadri power station near Visakhapatnam, Andhra Pradesh, marking a significant step in the country’s transition to clean energy. The plant, which aims to produce one tonne of hydrogen per day (TPD), will use seawater as the primary input. This project is a part of NTPC's ongoing efforts to develop sustainable energy solutions and meet the targets of the National Green Hydrogen Mission.
 

To process seawater efficiently, NTPC has implemented an innovative low-carbon desalination plant that utilises waste heat from the thermal power plant’s flue gas. This technology allows the cost-effective conversion of seawater into hydrogen-grade water, a crucial component for hydrogen production. Producing hydrogen typically requires large amounts of purified water, with one kilogram of hydrogen needing 12–13 kilograms of water. Given the growing water scarcity in India, using seawater and wastewater for hydrogen production is a strategic move to reduce pressure on freshwater resources while supporting clean energy goals.
 

NTPC Green Energy Limited, a fully owned subsidiary of NTPC, is leading the charge on several fronts to advance India’s green hydrogen capacity. The Simhadri project demonstrates the company’s commitment to developing technologies that can enable large-scale, low-cost hydrogen production from non-traditional water sources. Through this initiative, NTPC aims to contribute to India's renewable energy ambitions and help meet its climate goals.
