NTPC Limited has commissioned India’s first green hydrogen blending project. Green hydrogen blending has been started in the piped natural gas (PNG) network of NTPC Kawas township, Surat. The project is a joint effort of NTPC and Gujarat Gas Limited (GGL). After the start of the blending operation, NTPC Kawas held awareness workshops for township residents with help of GGL officials.
This set-up is geared up to supply H2-NG (natural gas) to households of Kawas township at Adityanagar, Surat. Green hydrogen in Kawas is made by electrolysis of water using power from an already installed 1 MW floating solar project.
The Petroleum and Natural Gas Regulatory Board (PNGRB), the regulatory body, has given approval for 5 per cent vol./vol. blending of green hydrogen with PNG to start with and the blending level will be scaled phase wise to reach 20 per cent. Green hydrogen when blended with natural gas reduces carbon dioxide emissions keeping net heating content same.
Recently in December 2022, Adani New Industries signed a development and licensing agreement with Cavendish Renewable Technology (CRT), a Melbourne based hydrogen technology company. The partnership will include development of alkaline electrolysers, polymer exchange membranes (PEM), anion exchange membranes (AEM), and CRT’s innovative ‘C Cell’ technology for mass-scale production.
