Nearly 4,000 Adani Total Gas Ltd. customers will soon have access to a cleaner fuel source, with the city gas distributor blending green hydrogen in natural gas for cooking in a town in Ahmedabad.

The company announced on Sunday that it started blending 2.2 percent to 2.3 percent of green hydrogen in piped natural gas and supplied them to households in Shantigram.

“We are thrilled to announce the successful commissioning of our hydrogen blending system and in-situ hydrogen generation at Adani Shantigram, Ahmedabad,” said ATGL in a LinkedIn post.

Green Revolution

Green hydrogen is produced through electrolysis, where electricity derived from renewable energy sources splits water into hydrogen and oxygen.

Blending this green hydrogen into natural gas reduces carbon emissions in cooking, household, or industrial heating.

“By blending hydrogen with natural gas, we are lowering greenhouse gas emissions, enhancing energy security, and supporting sustainable development,” the company said in its post.

The firm will slowly increase the green hydrogen blend in natural gas to 5 percent and ultimately to 8 percent. It will also widen supplies beyond Shantigram to other parts of Ahmedabad and eventually across areas where it holds a city gas license.

Presently, state-owned power generator NTPC supplies green hydrogen blended natural gas to households in Kawas in Surat district, Gujarat.

State-owned gas utility GAIL (India) Ltd is also doing a small pilot in Indore, Madhya Pradesh, to supply compressed natural gas doped with grey hydrogen.

Assessing the Feasibility

Grey hydrogen, the most commonly produced fuel, is primarily derived from natural gas through a process known as steam methane reforming.

While green hydrogen is widely viewed as a future fuel for decarbonization, its corrosive nature challenges existing infrastructure.

Tests have confirmed that hydrogen can be safely blended with natural gas at concentrations of up to 10 percent without impacting pipelines or equipment.

However, higher concentrations, up to 30 percent, would require modifications, such as improved material grades and increased wall thickness in pipelines.

Nevertheless, the ATGL initiative to blend green hydrogen with natural gas represents a significant milestone in India’s journey toward sustainable energy utilization.
