Adani Group has initiated the blending of green hydrogen into the natural gas supplied for cooking in households across parts of Ahmedabad, aiming to reduce emissions and achieve net-zero targets. Adani Total Gas Ltd, the city gas joint venture between the Adani Group and French energy giant TotalEnergies, has begun incorporating 2.2-2.3% green hydrogen into piped natural gas supplies in Shantigram, as announced in a LinkedIn post by the company.
The green hydrogen, produced through renewable energy sources like wind and solar, is generated via electrolysis, a process that splits water into hydrogen and oxygen. This blended gas is then utilized for heating and power generation, resulting in lower emissions compared to using natural gas alone.
"We are thrilled to announce the successful commissioning of our Hydrogen Blending System and in-situ Hydrogen Generation at Adani Shantigram, Ahmedabad," said Adani Total Gas Ltd (ATGL). This project aims to provide hydrogen-blended natural gas to approximately 4,000 domestic and commercial consumers.
Previously, state-owned power generator NTPC has supplied green hydrogen blended natural gas to households in Kawas, Surat, while GAIL (India) Ltd is conducting a pilot project in Indore to supply CNG mixed with grey hydrogen. However, ATGLs initiative is the largest of its kind to date.
The company plans to gradually increase the green hydrogen blend in natural gas to 5% and ultimately to 8%, expanding supplies beyond Shantigram to other regions of Ahmedabad and areas where it holds a city gas license.
"This achievement marks a significant step towards reducing our carbon footprint and transitioning to cleaner energy solutions," ATGL stated. "By blending hydrogen with natural gas, we are lowering greenhouse gas emissions, enhancing energy security, and supporting sustainable development." ATGL CEO Suresh P. Manglani emphasized that this pioneering initiative represents a crucial step toward decarbonizing Indias energy landscape.
While green hydrogen is being promoted as a future fuel due to its zero carbon emissions, challenges remain, including its potential to corrode pipelines and equipment. Tests have shown that up to 10% hydrogen can be blended in natural gas without affecting pipeline integrity. Currently, ATGL is blending at 2.2-2.3% and aims to increase this to 5% and eventually to 8%, which is the current regulatory limit. A blend of up to 30% may be achievable with modifications to the material grade and wall thickness of pipelines and equipment.
Hydrogen energy is a vital element in the global transition towards reducing greenhouse gas emissions and tackling climate change, although its high production costs continue to pose challenges. |
