NTPC's Green Hydrogen Initiative in Visakhapatnam
Key Ideas
- NETRA, NTPC's R&D center, is establishing a 1 TPD seawater to green hydrogen plant in Visakhapatnam, using low-carbon desalination technology.
- NTPC is leveraging waste heat from thermal power plant flue gas for seawater processing, reducing costs for hydrogen production.
- The Government of India is promoting the development of technologies to produce hydrogen from low-grade water sources like seawater and wastewater due to water scarcity.
- NTPC Green Energy Limited, a subsidiary of NTPC, is actively contributing to the National Green Hydrogen Mission's objectives.
NETRA, the Research & Development (R&D) center of NTPC, is making strides in the green hydrogen sector by establishing a 1 Tonnes Per Day (TPD) seawater to green hydrogen plant at NTPC Simhadri near Visakhapatnam, Andhra Pradesh. This initiative involves an innovative approach where NTPC is using low-carbon desalination technology powered by waste heat from the thermal power plant flue gas, which facilitates the cost-effective conversion of seawater into hydrogen-grade water. Considering the significant water requirements for hydrogen production (12-13 kg of purified water for 1 kg of hydrogen), the Indian government is emphasizing the need to explore technologies that can enable hydrogen production from unconventional water sources like seawater and wastewater, especially in light of water scarcity issues in the country. Additionally, NTPC Green Energy Limited, a wholly-owned subsidiary of NTPC, is actively engaged in exploring various pathways to align with the targets set by the National Green Hydrogen Mission. These efforts by NTPC demonstrate a positive step towards sustainable and innovative hydrogen production in India.
