Following the implementation of E20 petrol to manage fuel demand and prices, the Indian government is now shifting its focus toward the domestic energy sector. In a significant move to bolster energy security and reduce reliance on expensive imports, plans are underway to introduce hydrogen blending in Piped Natural Gas (PNG) used for cooking. This initiative comes as a strategic response to global energy fluctuations, particularly those triggered by conflicts in the Gulf region, while historically, when the Gulf War commenced, India faced a severe oil crisis due to the closure of the Strait of Hormuz, which disrupted crude oil imports. To mitigate such risks and control market volatility, the government mandated ethanol blending in petrol. Now, a similar approach is being adopted for cooking gas through the blending of hydrogen gas into the existing supply network.
The Proposed 5 Percent Blending Plan
The Petroleum and Natural Gas Regulatory Board (PNGRB) has already prepared a comprehensive draft outlining the roadmap for this transition, while according to the current proposal, the government aims to blend up to 5 percent hydrogen into the existing PNG supply. This draft is a critical step toward diversifying India's energy basket. If the proposal receives the necessary government approvals, households across the country will soon receive a mixture of natural gas and hydrogen through their kitchen pipelines. The primary objective behind this move is to decrease the volume of natural gas that India currently imports, thereby strengthening the national economy and ensuring a more stable supply chain for domestic consumers. The PNGRB is currently reviewing the technical feasibility of this integration across various urban gas distribution networks.
Economic Implications and Potential Price Hikes
While the move is strategically sound for energy independence, it carries significant economic implications for the end consumer. The PNGRB draft acknowledges that blending hydrogen into PNG could lead to an increase in cooking gas prices. The cost disparity between traditional natural gas and hydrogen is substantial. Currently, the price of one kilogram of hydrogen ranges between 387 and 397 rupees. In contrast, the price of natural gas stands at approximately 1067 rupees per MMBtu. The production of green hydrogen is even more capital-intensive, with costs estimated between 2880 and 2950 rupees per MMBtu. 7 times more expensive than conventional natural gas. Consequently, the integration of hydrogen into the PNG network is expected to make the final product more costly for households compared to the standard gas currently in use.
Safety Protocols and Implementation Timeline
Beyond the economic factors, safety remains a paramount concern for the regulatory authorities. Hydrogen is known to be a highly flammable gas with a high rate of diffusion, which necessitates rigorous testing before it can be safely introduced into the domestic pipeline infrastructure. The PNGRB and other safety agencies are currently scrutinizing every layer of the proposal to ensure operational readiness. This includes evaluating the integrity of existing pipelines, the risk of hydrogen embrittlement in metal pipes, and the compatibility of household appliances with the new gas blend. The draft is currently open for public and expert suggestions to identify potential hazards. Even if the plan receives immediate approval, experts believe that the full-scale implementation and technical upgrades required for this project could take 2 to 3 years. The project will only move forward once a No Objection Certificate (NOC) is secured from all relevant safety and security agencies, ensuring that the transition doesn't compromise public safety in residential areas.
