Indian Oil Corporation Compressed Biogas Strategy, 25 Petronet LNG Plants, and ₹33 B CAPEX Plan (2024 to 2026)

India’s Energy Security Risk: Indian Oil Corporation’s Strait of Hormuz Exposure

India’s energy security is critically exposed to geopolitical volatility at maritime chokepoints, compelling state-owned firms like Indian Oil Corporation to pursue a high-cost, dual strategy of expanding domestic refining while building out alternative fuel supply chains. With an 85-88% dependence on crude oil imports, India’s economy is highly vulnerable to supply disruptions, particularly through the Strait of Hormuz, which handles a significant portion of its energy imports. This exposure dictates a strategic pivot from merely securing foreign crude to actively developing sovereign energy production capabilities.

• The national strategy has visibly bifurcated in the 2025-2026 period, moving beyond securing crude supplies to a parallel build-out. This involves reinforcing fossil fuel processing through refinery capacity expansions while simultaneously creating new domestic fuel streams from compressed biogas (CBG) and green hydrogen to mitigate deep-seated import vulnerabilities.
• Indian Oil Corporation’s response is a massive capital expenditure program, projected to be between ₹33, 000 crore and ₹40, 000 crore annually in the coming years. This capital is being deployed not just to expand refining but to build parallel infrastructure for LNG, biofuels, and hydrogen, representing a fundamental shift from a single-fuel focus to a multi-vector energy security approach.
• This strategic shift is driven by relentless demand growth, with India’s oil consumption projected to rise from 5.55 million barrels per day (bpd) in 2024 to 5.74 million bpd in 2025. This growth makes inaction on domestic supply and infrastructure an untenable risk to economic stability.

Indian Oil Corporation ₹40, 000 Crore CAPEX for Refining and Renewables (FY 26-FY 29)

Indian Oil Corporation has committed to a sustained, high-volume capital expenditure program averaging nearly ₹40, 000 crore ($4.8 billion) annually from FY 27-FY 29, with specific allocations aimed at both expanding core refining capacity and funding a nascent renewable energy portfolio. This spending plan confirms the company’s dual mandate to secure India’s immediate energy needs with fossil fuels while laying the financial groundwork for a long-term transition. This level of investment is significant, rivaling the capital plans of global energy firms like Total Energies, which has a medium-term target of $16-18 billion for its worldwide operations.

• The investment cycle shows a consistently high level of spending, with planned CAPEX of ₹35, 000 crore for FY 25, ₹33, 000 crore for FY 26, and ₹32, 700 crore for FY 27. This precedes a further ramp-up to the ₹40, 000 crore annual level, indicating a multi-year infrastructure expansion program.
• A clear signal of the parallel investment strategy is the ₹5, 000 crore specifically earmarked for renewables within the FY 27 budget. While a smaller portion of the total, it represents a dedicated capital pool for building out alternative energy assets.
• The majority of the capital still supports the core business, as shown by the ₹33, 494 crore CAPEX plan for FY 25-26 focused on refinery and petrochemical expansion. This is essential to meet immediate domestic demand and reduce the country’s reliance on imported finished petroleum products.

Indian Oil Corporation’s Biofuel JVs: 25 CBG Plants with Petronet and GPSR

Indian Oil Corporation is executing its domestic energy production strategy primarily through joint ventures focused on building a national network of Compressed Biogas (CBG) plants, partnering with both public and private sector entities to de-risk project execution and secure feedstock. These partnerships are the most tangible evidence of its strategy to build a domestic, non-fossil fuel supply chain to reduce reliance on imported LNG and other hydrocarbons.

• The collaboration with Petronet LNG, announced in January 2026, aims to jointly develop 25 CBG plants across India. The structure delegates project implementation, including feedstock sourcing and offtake arrangements, to Petronet, demonstrating a strategic division of labor to accelerate deployment.
• A separate joint venture structure with GPSR Renewables, confirmed in March 2026, involves other major state-owned oil marketing companies like Bharat Petroleum and Oil India. This signals a coordinated, industry-wide push to establish a viable CBG ecosystem under the government’s Sustainable Alternative Towards Affordable Transportation (SATAT) initiative.
• Contrasting with the commercial-scale CBG ventures, a technology development partnership with the Indian Institute of Science (IISc) for a biomass-to-hydrogen demonstration plant shows a longer-term strategic intent. This initiative explores a more technologically advanced pathway to creating domestic, non-fossil fuel-based hydrogen.

Domestic Focus: Indian Oil Corporation’s India-Centric Infrastructure Buildout

Unlike global majors that deploy capital across continents, Indian Oil Corporation’s strategic investments are almost exclusively focused within India’s borders. The company is building out a comprehensive domestic energy infrastructure network, from coastal import terminals and inland refineries to decentralized biofuel production sites, all designed to serve a singular, rapidly growing national market and reduce external dependencies.

• The geographic focus has shifted significantly in recent years. Before 2025, a key part of the company’s international strategy was diversifying its sources of crude oil from different countries. In the 2025-2026 period, the emphasis has pivoted to building domestic production and processing assets to reduce the need for those imports in the first place.
• Refinery expansion projects are entirely domestic, aimed at increasing India’s internal processing capacity to convert crude oil into finished products like gasoline and diesel. This enhances value capture within the country and provides a buffer against refined product import reliance.
• The push into biofuels is creating a new map of decentralized energy production. The CBG plant joint ventures with Petronet and GPSR are planned for sites “across India, ” leveraging local agricultural and municipal waste streams to produce energy close to consumption centers.
• Critical import infrastructure, such as the planned expansion of the Ennore LNG Terminal, is also being constructed on Indian soil. This strengthens the country’s capacity to handle transitional fuels like LNG, which are secured via long-term contracts to hedge against volatile spot markets.

Commercial Scale Refining vs. Pilot Stage Hydrogen: Indian Oil’s Dual Tech Focus

Indian Oil Corporation’s technology strategy operates on two distinct and parallel timelines: deploying mature, commercial-scale technologies for its core refining business to ensure immediate energy supply, while simultaneously investing in pilot- and demonstration-scale projects for next-generation fuels like green hydrogen and advanced biofuels.

• Mature Technology: In its core business, IOCL is maximizing the output of its existing asset base, pushing refinery throughput to 109.7% utilization in early 2026. The strategy relies on proven, bankable refining processes to deliver the massive volumes of fuel India requires today.
• Emerging Commercial Technology: The company’s push into Compressed Biogas (CBG) is moving from policy to practice, with joint ventures established in 2026 to build commercial-scale plants. Additionally, the plan to begin co-processing biofuels at its refineries in 2026 represents a key step in leveraging existing infrastructure to produce lower-carbon fuels.
• Pilot and R&D Stage: The collaboration with IISc on a biomass-to-hydrogen plant is explicitly a small-scale (88 tonnes H 2/year) demonstration project to prove a new technology pathway. Similarly, the hydrogen-powered mobility solutions showcased at India Energy Week 2026 are still progressing from pilot concepts to practical applications, and are not yet ready for mass deployment.
• Strategic Shift: The period from 2021-2024 involved significant policy formation and conceptual planning for these alternative fuels. The 2025-2026 period is defined by concrete investment decisions and the launch of physical projects, such as the CBG joint ventures, validating the company’s strategic pivot into new technology areas.

SWOT Analysis: Indian Oil Corporation’s Strengths and Geopolitical Threats

Indian Oil Corporation’s dominant market position as a state-owned enterprise and its access to massive capital provide a strong foundation for executing its dual energy strategy. However, this strength is directly challenged by its extreme vulnerability to geopolitical supply disruptions and the long-term risk of its heavy investments in fossil fuel infrastructure becoming stranded assets in a rapidly decarbonizing world.

• The company’s key strength is its ability to direct large-scale, state-backed capital towards national strategic priorities, a position that has been validated by the multi-billion-dollar CAPEX plans announced for FY 25-FY 29.
• Its primary weakness remains an unavoidable structural reality: an 85-88% dependence on imported crude oil, which exposes its core business and the Indian economy to severe price and supply shocks.
• The biggest opportunity lies in aligning its investments with India’s growing energy demand and national policies promoting biofuels and green hydrogen, positioning itself as the primary execution vehicle for the country’s energy transition.
• The most significant threat is geopolitical volatility, particularly in the Middle East, which could disrupt supply chains through the Strait of Hormuz. A secondary but growing threat is the potential for its new, long-life fossil fuel assets to be devalued by faster-than-expected global shifts to clean energy.
