Introduction

India is at a turning point where national energy security directly dictates sovereign stability. The country is heavily dependent on natural gas imports, with 51% of its supply coming from abroad, making it vulnerable to disruptions in the global supply chain and geopolitical instability. This structural exposure was underscored in the first quarter of FY27, when India’s natural gas import bill rose 24% year-over-year to $5.6 billion, and domestic LPG cylinder prices jumped from ₹853 to ₹942. To mitigate these external shocks, the policy makers and industrial conglomerates are aggressively promoting the use of Compressed Biogas (CBG), a purified, high-methane renewable gas derived from organic wastes such as cattle dung, paddy straw (parali), sugarcane waste, municipal waste, and sewage.

India’s CBG sector offers an attractive “one-shot, four-target” investment thesis for institutional investors, as it can replace costly fossil fuel imports, reduce industrial emissions, upgrade rural waste management, and enhance farmer incomes, but the commercialization of the sector is hindered by significant supply chain challenges. We explore past policy failures, review the transformative approach of the expanded ₹23,731 crore Gowardhan scheme, dissect biomass aggregation logistics, and map out the strategic pathway for capital investment in energy and agricultural value chains.

The $5.6 Billion Import Burden: India’s Bio-Resource Paradox

The paradox of India’s energy transition is the stark difference between bio-resource availability and operationalisation. Every year, India produces about 50 crore (500 million) metric tons of crop residue and 100 crore (1 billion) metric tons of cattle dung. This huge organic waste stream could be converted into purified CBG, producing 4 to 6 crore (40 to 60 million) metric tons of renewable fuel annually. If India imports 26 million metric tons of Liquefied Natural Gas (LNG) in FY26, then the complete utilization of this bio-resource potential would make India completely independent of natural gas imports. Moreover, CBG scaling reduces the intensity of environmental risks, directly reducing seasonal stubble burning in key agricultural areas of Punjab, Uttar Pradesh and Madhya Pradesh.

But real implementation has fallen short of initial policy goals. The national target was to install 5,000 commercial CBG plants by 2023 under the 2018 Sustainable Alternative Towards Affordable Transport (SATAT) initiative and Swachh Bharat Mission frameworks. However, by August 2026, only 217 facilities were operational, with a 4% achievement rate against targeted capacity. Consequently, in 2025 India realized less than 1% of its theoretical CBG capacity. This gap highlights the need for policy goals to be accompanied by a structured logistics and unit economics to mobilize private capital at scale.

Deconstructing the Bottlenecks: Biomass Logistics, Capacity Drag and Corporate Pivots

Investors need to look at the microeconomics of biomass supply chains to understand the reasons for the previous slowdown. The main constraint is the inconsistent supply of feedstock. CBG facilities are designed to suit the characteristics of the feedstock, and a plant that is optimized for sugarcane bagasse cannot easily process paddy straw without significant yield loss. The generation of crop residues is seasonal, and the post harvest collection window is short, necessitating storage facilities which are limited in availability in rural India. On the other hand, cattle dung production is steady throughout the year, but collection is spread out among millions of small dairy farms. Another structural challenge is transport economics.

In response, industrial leaders are going for vertical integration. Reliance Industries has pledged to invest ₹100 crore in a partnership with the Indian Council of Agricultural Research (ICAR) to study 11 non-seasonal high-yield grass species, ensuring a more stable supply of feedstock and providing up to ₹12 lakh per hectare in farmer income. In 2026, the automotive company Maruti Suzuki invested ₹561 crore in dedicated CBG plants. Praj Industries, a technology provider, said that the design change in FY25 was to place CBG plants in the feedstock fields instead of the conventional 20-30 km away locations, which helps in maintaining the moisture of biomass and reduces transportation costs.

Competition for biomass from other sectors further constrains feedstock availability. The 2022 Samarth Mission required coal power plants to co-fire biomass pellets (5% in FY25 and 7% in FY26) to reduce thermal power emissions. By FY26, however, only 75 of the 620 operational thermal power plants (around 10%) achieved this target, highlighting systemic biomass collection gaps affecting both power generation and biogas production.

Navigating Policy Pivots

Guaranteed pricing makes CBG development more bankable, but makes it more challenging for CGD operators. During global energy disruptions, CGD entities are exposed to higher import prices for LNG, which creates tension in the transmission of price increases to end consumers. On the supply side, GOBARdhan offers capital assistance of ₹2 crore per ton-per-day (TPD) of installed capacity, credit guarantees, funding for trunk pipeline connectivity, and a dedicated CBG Ecosystem Challenge Fund to modernize biomass aggregation. International capital involvement is also growing, with India’s July 2026 bilateral agreement with Japan for 1,000 integrated CBG and organic fertilizer plants.

In the end, value-chain monetization goes beyond biomethane sales. Like crude oil refineries, the economics of CBG plants rely on monetizing the residual byproducts, in this case, Fermented Organic Manure (FOM) from the liquid bio-slurry. FOM replenishes soil organic carbon and enhances the absorption of chemical fertilizers. India is highly dependent on imported Urea and Diammonium Phosphate (DAP) and scaling up FOM adoption directly cuts down on the national fertilizer import liabilities. The Indian Biogas Association (IBA) has suggested that by 2030, 10% of chemical fertilizers must be blended with FOM, providing investors with a dual-revenue business model that combines clean energy and sustainable agriculture.

Conclusion

The Compressed Biogas sector in India is poised to be a key player in the realm of energy sovereignty, agricultural sustainability, and industrial decarbonization. Although the initial policy initiatives were logistical hurdles and had low capacity utilisation, the ₹23,731 crore GOBARdhan framework offers the required blending off-take, fixed procurement pricing, and capital assistance to de-risk private investment. Investors who are able to master feedstock aggregation, implement facility configurations adjacent to the fields, overcome the biomass competition from thermal power plants, and monetize the byproducts of organic fertilizer production fully will be the ones to take the lead in the market. CBG is one of the most compelling infrastructure opportunities in emerging market energy transitions as India strives to lower its $5.6 billion quarterly natural gas import exposure.
