A recent study by Engineers India (EIL) and IIT Kanpur suggests that up to 5 per cent green hydrogen can be blended with piped natural gas (PNG) without causing any adverse impact on the pipeline infrastructure. This development is significant for India, as it aims to reduce its reliance on fossil fuel imports, especially liquefied natural gas (LNG). Green hydrogen, produced from renewable energy (RE) sources and electrolysis, is being explored by Central public sector undertakings (CPSUs) like NTPC and GAIL through pilot projects. These projects involve blending green hydrogen with PNG at varying percentages to test feasibility and efficiency. Additionally, the government is studying the cost dynamics and reliability of transporting green hydrogen through pipelines from renewable energy zones (REZs) to ports for both domestic use and exports. Various entities including GAIL, Indian Oil Corporation (IoCL), and NTPC are collaborating to assess the feasibility of setting up a pipeline network for green hydrogen transportation. While the initiative holds promise for energy sustainability and reducing carbon emissions, challenges such as hydrogen embrittlement in pipelines and appliances need to be addressed. The Petroleum and Natural Gas Regulatory Board (PNGRB) is also working on exploring avenues for transporting green hydrogen through natural gas transmission lines by blending it with natural gas, which is seen as a cost-effective option. India's annual demand for hydrogen is substantial, accounting for about 6 per cent of the global demand, signaling the country's potential to lead in green hydrogen adoption.
