New Delhi: State gas utility GAIL (India) Ltd on Monday said it has commenced India's first-of-its-kind project of mixing hydrogen into the natural gas system at Indore, Madhya Pradesh.

The hydrogen blended natural gas will be supplied to Avantika Gas Ltd, one of GAIL's joint ventures with HPCL, for retailing of CNG to automobiles and piped natural gas to households in Indore, the company said in a statement.

"In line with the National Hydrogen Mission, GAIL has started hydrogen blending as a pilot project to establish the techno-commercial feasibility of blending hydrogen in City Gas Distribution (CGD) network. This project marks the stepping stone of India's journey towards hydrogen-based and carbon-neutral future," it said.

GAIL. started injection of grey hydrogen at the city gate station (CGS), Indore.

"This grey hydrogen would subsequently be replaced by green hydrogen," it said.

GAIL has already obtained the necessary regulatory permissions to commence the project.

Zero-emission hydrogen is the latest buzzword around the world. Depending on the source, the hydrogen is classified as blue, green, or grey.

Blue hydrogen is when natural gas is split into hydrogen and CO2. The CO2 is captured and then stored. Grey hydrogen is a similar process to blue hydrogen but the CO2 is not captured and is released into the atmosphere.

Green hydrogen is hydrogen produced by splitting water by electrolysis using electricity from renewable energy sources such as wind or solar. This produces only hydrogen and oxygen. The hydrogen is used and oxygen is vented into the atmosphere with no negative impact.
