NETRA, the R&D centre of NTPC, is setting up a 1 tpd seawater to green hydrogen plant at NTPC Simhadri near Visakhapatnam in Andhra Pradesh. For seawater processing, NTPC has implemented a low-carbon desalination plant utilizing waste heat from the thermal power plant flue gas, enabling low-cost conversion of seawater into hydrogen-grade water.
Producing 1 kg of hydrogen typically requires 12-13 kg of purified water. Given the water scarcity in the country, Government of India is prioritizing the development and demonstration of technologies that would enable hydrogen production from low-grade water sources, such as seawater and wastewater.
NTPC Green Energy Limited, a wholly-owned subsidiary of NTPC, is actively working on various pathways to meet the targets of the National Green Hydrogen Mission.
