India's Compressed Biogas (CBG) Ecosystem: A Comprehensive Review of Central and State Government Support, Benefits, and Future Trajectory

 


I. Background

India is strategically leveraging Compressed Biogas (CBG) to address its multifaceted national objectives concerning energy security, waste management, and climate change. The nation aims to significantly reduce its reliance on fossil fuel imports, manage vast organic waste streams, and foster a circular economy. This report details the multi-faceted support from both central and state governments, outlining the tangible benefits, current progress, and the roadmap for future growth in the CBG sector. A robust policy framework, substantial financial incentives, and a clear market off-take strategy characterize the government's approach. While significant strides have been made, ongoing challenges in feedstock aggregation, affordable financing, and regulatory streamlining persist, necessitating continued adaptive policy measures to fully unlock India's immense CBG potential.

II. Introduction: The Strategic Importance of Compressed Biogas in India

India's rapidly expanding economy faces a dual challenge: a burgeoning energy demand, with approximately 77% of its crude oil and 50% of its natural gas requirements met through imports, and a pressing waste management crisis. The country generates an estimated 62 million metric tons of waste annually, of which only 70% is collected, and a mere 12 million tons undergo treatment, leaving a substantial 31 million tons to be disposed of in landfills. Traditional waste disposal methods, including uncontrolled landfilling and open burning, are significant contributors to methane emissions, a potent greenhouse gas, and exacerbate air pollution. In response to these critical issues, India has committed to ambitious climate goals, including a national objective of achieving net-zero emissions.

Compressed Biogas (CBG) emerges as a pivotal solution within this complex landscape. Produced from diverse organic waste streams through anaerobic digestion, CBG is a clean, renewable fuel with properties comparable to Compressed Natural Gas (CNG). Its production process effectively transforms various feedstocks, such as agricultural residue, cattle dung, municipal solid waste (MSW), and food scraps, into a high-value energy source. The adoption of CBG not only reduces greenhouse gas emissions and improves air quality by mitigating practices like stubble burning  but also offers a viable alternative to fossil fuels, thereby bolstering India's vision of energy access, efficiency, sustainability, and security. The consistent emphasis on India's simultaneous struggles with energy import dependency, massive waste generation, and environmental pollution underscores a deliberate, multi-pronged policy approach by the Indian government. CBG is strategically positioned as a transformative solution because it offers synergistic benefits: enhancing energy security by reducing Liquefied Natural Gas (LNG) imports , contributing to environmental sustainability by managing waste and reducing emissions , and fostering rural economic development through job creation and supplementary income for farmers. This integrated approach is a key underlying theme of India's broader bioenergy strategy.

III. Central Government Support for Compressed Biogas (CBG)

The Central Government of India has implemented a comprehensive suite of policies and initiatives to foster the growth of the CBG sector, addressing various aspects from production incentives to market integration.

A. Flagship Initiatives

The Sustainable Alternative Towards Affordable Transportation (SATAT) Initiative

The SATAT initiative, launched by the Ministry of Petroleum & Natural Gas on October 1, 2018, is designed to incentivize entrepreneurs to establish CBG plants and supply the produced fuel to Oil Marketing Companies (OMCs). This scheme initially set an ambitious target of producing 15 MMT of CBG from 5,000 plants by 2023. While this initial target proved highly ambitious and was not fully realized, the scheme has successfully generated significant interest, evidenced by over 2,000 Letters of Intent (LOIs) issued. As of November 30, 2024, 80 CBG plants have been commissioned under SATAT, with an additional 72 plants reported to be in various stages of construction. Furthermore, in the fiscal year 2024-25, 94 CBG plants collectively sold 31,423 tons of CBG.

A crucial aspect of SATAT is the assured off-take and pricing mechanism. OMCs provide a long-term off-take pricing agreement, typically spanning 10 to 15 years, with a basic price of ₹46 per kilogram (plus 5% GST) for CBG that adheres to the IS 16087:2016 quality standards. This guaranteed off-take and stable pricing mechanism is a critical policy lever specifically designed to de-risk investments in the nascent CBG sector, thereby attracting private entrepreneurs and fostering market confidence. It acknowledges that a predictable and stable market for the end product is as crucial as capital subsidies for ensuring long-term project viability. The government's adaptive approach, evident in adjusting the target for commissioned plants to a more realistic 1000-1200 large-size plants by 2030 , demonstrates a willingness to recalibrate based on ground realities and implementation challenges.

GOBARdhan Yojana

The Galvanizing Organic Bio-Agro Resources Dhan (GOBARdhan) initiative was launched in April 2018 as a component of the Swachh Bharat Mission (Grameen). Its primary objective is to transform organic waste, such as cattle dung and agricultural residues, into valuable resources like biogas, CBG, Bio-CNG, and organic manure. The scheme actively promotes waste-to-energy projects in rural areas by providing subsidies and financial support. The Union Budget 2023-24 set a target for establishing 200 new CBG plants under GOBARdhan, with 75 of these specifically designated for urban areas. As of December 4, 2024, 37 CBG plants are reported as functional under the GOBARdhan scheme, with an additional 133 plants in various stages of development towards the budget announcement target. Notably, the number of functional CBG plants under this initiative has seen impressive year-on-year growth, increasing from just 19 in 2020 to 125 currently. Financial assistance includes a subsidy of ₹37,000 per unit for biogas plants  and up to ₹50 lakh per district for setting up community-level biogas plants under Swachh Bharat Mission-Grameen Phase II (2020-2026).

This initiative demonstrates a sophisticated and holistic policy design that simultaneously addresses rural economic upliftment, environmental sanitation, and renewable energy generation. By focusing on decentralized production models and leveraging locally available waste resources (cattle dung, agri-residue), it aims to create sustainable livelihood opportunities and significantly improve hygiene in rural areas, directly supporting the achievement of Open Defecation Free (ODF)-plus status under SBM-G. The strong emphasis on the production and utilization of organic manure (bio-slurry/Fermented Organic Manure) as a valuable byproduct further underscores the government's commitment to a circular economy model.

Ministry of New and Renewable Energy (MNRE) Bio-Energy Programme

The MNRE actively supports biogas projects through its Bio-Energy Programme, offering Central Financial Assistance (CFA) and incentives for power generation and thermal applications. Under the Waste to Energy Programme, substantial financial support is provided: for new Biogas to CBG plants, a CFA of ₹4.00 Crore per 4800 kg/day capacity is available, capped at a maximum of ₹10.00 Crore per project. For projects converting existing biogas plants to CBG, the CFA is ₹3.00 Crore per 4800 kg/day, also with a maximum of ₹10.00 Crore per project. A special, enhanced CFA (20% higher) is provided for projects located in Special Category States (e.g., North Eastern states, Himachal Pradesh, Uttarakhand, Jammu & Kashmir, Ladakh) and for projects by Registered Gaushalas that primarily use cattle dung as feedstock.

Eligible applicants encompass a wide range of entities, including companies, LLPs, NGOs, Trusts, Cooperatives, Special Purpose Vehicles (SPVs), Joint Ventures, Gaushalas, local bodies, and private developers. Projects must involve the installation of new machinery to qualify. The application process is streamlined through the BioURJA Portal, requiring an initial proposal submission, followed by in-principle approval from MNRE. Plants must be commissioned within 24 months (for CBG & Power Projects) and demonstrate a minimum 80% Plant Load Factor (PLF) for 3 months to claim the full CFA. An advance subsidy, up to 50% of the CFA, can be released during the construction phase for SATAT-linked projects that have secured a loan covering at least 50% of the total project cost. The MNRE is also in discussions for the second phase of the National Bioenergy Programme, which has a total allocation of ₹1,700 crore. This comprehensive financial support mechanism signifies a strategic effort to de-risk initial capital investments and ensure long-term operational efficiency. The performance-linked disbursement encourages robust project planning, construction, and sustained operation, while the advance subsidy for SATAT-linked projects highlights effective inter-ministerial coordination and a concerted push for faster deployment by alleviating upfront financial burdens. The differentiated incentives for special category states and gaushalas aim for equitable regional development and targeted feedstock utilization within the CBG sector.

B. Enabling Policies and Financial Mechanisms

Biomass Aggregation Machinery (BAM) Scheme

The Ministry of Petroleum and Natural Gas (MoPNG) launched the Financial Assistance Scheme for Procurement of Biomass Aggregation Machinery (BAM) on February 2, 2024. This scheme directly addresses a significant bottleneck in CBG production: the often slow, labor-intensive, and unmechanized process of feedstock collection and management. A total budget of ₹564.75 Crore has been allocated for this scheme for the period FY 2023–24 to FY 2026–27. Under this scheme, a 4 TPD CBG project is eligible for a subsidy of ₹1.80 Crore, calculated on a pro-rata basis, with a maximum cap of ₹9 Crore per project. To be eligible, plants must have a minimum capacity of 2 TPD, utilize at least 50% agri-residue, and be registered on the GOBARdhan portal. This scheme represents a crucial policy intervention designed to professionalize and mechanize the feedstock supply chain, which is often a significant operational and cost challenge for CBG plants. By subsidizing BAM, the government aims to ensure a consistent, high-quality, and cost-effective supply of raw materials, thereby improving overall plant efficiency, reliability, and long-term viability. This proactive measure demonstrates a comprehensive understanding that successful CBG production necessitates support across the entire value chain, not just at the conversion facility.

Scheme for Development of Pipeline Infrastructure (DPI)

The Government of India has approved the "Scheme for Development of Pipeline Infrastructure (DPI) for injection of Compressed Biogas (CBG) in City Gas Distribution (CGD) network". This scheme provides financial assistance for establishing CBG-CGD grid connectivity for 100 CBG projects. A financial outlay of ₹994.50 crore has been allocated for this scheme for the fiscal years FY 2024-25 to FY 2025-26, with plans to support 50 projects in each year. The scheme offers a maximum financial assistance of ₹28.75 crore per project for the construction of pipelines (Steel/MDPE) up to 75 kilometers. An online portal for submitting applications under the DPI Scheme was activated on September 1, 2024. This initiative is deemed crucial for seamlessly integrating CBG into existing local gas grids, thereby enhancing its accessibility and simplifying distribution, particularly for plants located in rural areas. However, it is important to note that meeting stringent pipeline injection standards requires advanced purification processes. This scheme directly addresses the "last mile" connectivity challenge for CBG, enabling its injection into existing City Gas Distribution (CGD) networks. This is vital for expanding CBG's market reach beyond localized consumption, significantly reducing transportation costs (which would otherwise involve cascades), and facilitating its role as a mainstream energy source. It signals a strategic shift in policy from merely incentivizing production to ensuring comprehensive market integration and efficient delivery to consumers.

Compressed Biogas Blending Obligation (CBO)

In a significant move, the National Biofuels Coordination Committee (NBCC), chaired by the Union Petroleum Minister, approved the introduction of phase-wise mandatory blending of CBG in both Compressed Natural Gas (CNG) for transport and Piped Natural Gas (PNG) for domestic segments of the City Gas Distribution (CGD) sector. This mandate is designed to stimulate demand for CBG within the CGD sector, facilitate import substitution for Liquefied Natural Gas (LNG), conserve foreign exchange, promote a circular economy, and contribute to India's net-zero emission targets. The CBO will remain voluntary until the fiscal year 2024-25. Mandatory blending will commence from FY 2025-26 at 1%, progressively increasing to 3% in FY 2026-27, 4% in FY 2027-28, and reaching 5% from FY 2028-29 onwards. A Central Repository Body (CRB) will be established to monitor and implement this blending mandate. This mandatory blending is projected to facilitate significant investment (around ₹37,500 crores) and the establishment of approximately 750 CBG projects by 2028-29. This is arguably the most crucial policy shift, transforming the market dynamic from incentivizing supply to mandating demand. It provides long-term market certainty for CBG producers, ensuring consistent off-take, which is vital for attracting larger-scale investments and achieving the ambitious production targets. The phased implementation allows the industry to scale up its production capabilities gradually, making this blending mandate a cornerstone for the sustained growth and deeper integration of CBG into India's national energy mix.

National Biofuel Policy 2018

The National Biofuel Policy 2018 serves as the overarching framework that highlighted the increasing role of CBG in strengthening indigenous bioenergy generation, distribution, and consumption across India. The policy initially set indicative targets, such as 20% ethanol blending in petrol and 5% biodiesel blending by 2030. Recent amendments to this policy demonstrate the government's adaptive approach, including provisions to allow more diverse feedstocks for biofuel production and, notably, advancing the 20% ethanol blending target to ESY 2025-26 from the original 2030 timeline. The policy's fundamental aim is to reduce India's energy import dependency. This demonstrates the government's adaptive and proactive approach to biofuel policy, responding to evolving energy security needs, feedstock availability, and technological advancements. By broadening feedstock options, the policy aims to enhance the economic viability and scalability of overall biofuel production, including CBG, and to accelerate the national transition away from fossil fuels. The advancement of blending targets signals a heightened urgency and commitment to these renewable energy goals.

Priority Sector Lending Status for CBG Projects

To facilitate financing, loans for CBG plants have been accorded special treatment. The Reserve Bank of India (RBI) has expanded the scope of priority sector lending to include funding for start-ups up to ₹50 crore and loans specifically for farmers for the installation of CBG plants. This classification is intended to improve access to funds from scheduled commercial banks. This policy signals to financial institutions that CBG projects are a national priority, encouraging them to offer more favorable lending terms, such as potentially lower interest rates and extended repayment periods, and reducing their perceived risk associated with these projects. It directly addresses the identified challenge of "lack of affordable financing options" and high capital expenditure , thereby stimulating investment and accelerating project development by easing the financial burden on developers.

Proposed Tax Benefits and Carbon Credit Mechanisms

The Indian Biogas Association (IBA) has actively advocated for the creation of blanket corporate tax holidays for CBG production, specifically proposing a complete tax waiver during the initial years of operation, to attract greater investment into the sector. The IBA argues that such tax breaks would enable CBG producers to offer their products at more competitive prices, thereby boosting the adoption of CBG in India's energy mix and promoting the utilization of agricultural residues instead of burning them. Additionally, the IBA has proposed the development of a robust framework that would allow CBG plant promoters to sell carbon credits on both international and domestic platforms. This mechanism would not only create new revenue streams for producers but also significantly assist the Indian government in meeting its climate change targets. The potential of the carbon credit system as a substantial revenue generator has also been highlighted by the Ministry of Jal Shakti. These proposed financial incentives, particularly the corporate tax holidays, are crucial for significantly improving the economic viability and competitiveness of CBG production, especially given the high initial capital costs. The emphasis on carbon credits aligns India's CBG sector with global climate finance mechanisms, potentially attracting international investment and further incentivizing sustainable practices. This approach moves beyond direct subsidies to leverage market-based mechanisms, demonstrating a strategic evolution in policy to foster long-term sustainability and profitability for the sector.

IV. State-Level Biofuel Policies and Incentives for CBG

Many Indian states actively provide additional support and incentives for CBG projects, effectively complementing the central government's initiatives. These state-specific policies are critical as they are often tailored to address unique local conditions, specific feedstock availability (e.g., agricultural waste, municipal solid waste), and regional economic development priorities. This localized approach allows for more targeted interventions and fosters a competitive environment among states to attract investments in the CBG sector.

Organic fertilizers produced from bioenergy plants are promoted by the Agriculture & Farmer Welfare Department, with free trials conducted by State Agriculture Universities.


V. Swachh Bharat Mission and Waste-to-Energy Integration

The Swachh Bharat Mission (SBM) stands as a foundational initiative integral to India's waste-to-energy endeavors, particularly in the promotion of Compressed Biogas (CBG). SBM-Urban 2.0, launched on October 1, 2021, for a five-year period, places a strong emphasis on the scientific management of all waste fractions, including biodegradable waste. Concurrently, SBM-Grameen Phase II, active from 2020 to 2026, directly supports the establishment of community-level biogas plants under the GOBARdhan initiative. The overarching mission aims to achieve a "waste to wealth" transformation, converting organic waste into valuable resources such as CBG and organic manure.

Under the Solid Waste Management (SWM) component of SBM-Urban 2.0, the Ministry of Housing and Urban Affairs (MoHUA) provides crucial central financial assistance (CFA) for setting up Municipal Solid Waste (MSW)-based CBG plants in urban areas. This financial support is tiered based on the Urban Local Body (ULB) population, offering 25%, 33%, or 50% of the project cost, with a maximum cap of ₹18 crore per 100 TPD feedstock for Bio-methanation plants. The Union Budget 2023-24 further bolstered this integration by targeting the establishment of 500 new "Waste to Wealth" plants under GOBARdhan, which includes 200 compressed biogas (CBG) plants, with 75 of these specifically earmarked for urban areas. As of December 4, 2024, the Ministry of Housing and Urban Affairs reported that the construction of 67 CBG plants is expected to be initiated by March 2025 under its purview.

A prime example of successful waste-to-energy integration is Asia's largest municipal solid waste-based GOBARdhan plant, inaugurated by Prime Minister Narendra Modi in February 2022, located in Indore, Madhya Pradesh. This state-of-the-art facility processes an impressive 550 tonnes of municipal organic waste daily, yielding approximately 17,000 kg of Bio-CNG gas (equivalent to 17 TPD, with a consistent achievement of 15 TPD) and 100 tonnes of high-quality compost. The plant is projected to achieve a significant CO2 emission reduction of approximately 130,000 tonnes per year, which is intended for carbon credit generation. Operating with a high degree of automation and divided into three shifts for continuous functioning, this facility exemplifies the successful integration of waste management, renewable energy production, and circular economy principles under the broader umbrella of the Swachh Bharat Mission and GOBARdhan initiatives. The deep integration of the Swachh Bharat Mission with CBG development signifies a comprehensive national commitment to transforming waste from an environmental liability into a valuable resource. By promoting decentralized processing and providing substantial financial assistance specifically for MSW-based plants, the government is not only addressing the burgeoning urban waste crisis but also simultaneously creating a robust and diversified feedstock supply chain for CBG. The Indore plant serves as a scalable and replicable model, demonstrating the significant economic and environmental benefits of linking urban waste management with renewable energy production and carbon credit generation, thereby strongly reinforcing the principles of a circular economy.

VI. Current Status, Progress, and Timelines of the CBG Sector in India

The CBG sector in India is undergoing a transformative phase, driven by ambitious national targets and a supportive policy environment. While initial targets were highly aspirational, the government has shown adaptability in its approach, leading to steady progress.

Overall Progress Against National Targets

The SATAT initiative, launched in October 2018, initially set an ambitious target of establishing 5,000 CBG plants by 2023. As of November 30, 2024, 80 CBG plants have been officially commissioned, with an additional 72 plants reported to be in various stages of construction. In the fiscal year 2024-25, 94 CBG plants collectively sold 31,423 tons of CBG. Recognizing the complexities of scaling, the target has been realistically adjusted, with current expectations aiming for the setup of 1000-1200 large-size CBG plants by 2030.

Under the GOBARdhan initiative, the Union Budget 2023-24 set a target for establishing 200 new CBG plants. As of December 4, 2024, 37 of these targeted plants are functional, and 133 are reported to be in various stages of development. The number of functional CBG plants under GOBARdhan has shown significant growth, increasing from just 19 in 2020 to 125 currently.

The CBG Blending Obligation (CBO) is currently in a voluntary phase until the fiscal year 2024-25. Mandatory blending will commence from FY 2025-26 at 1%, progressively increasing to 3% in FY 2026-27, 4% in FY 2027-28, and reaching 5% from FY 2028-29 onwards. This mandatory blending is projected to facilitate significant investment (around ₹37,500 crores) and the establishment of approximately 750 CBG projects by 2028-29.

Number of Functional and Under-Construction CBG Plants

While India has over 5 million biogas plants, most are small-scale digesters. As of December 4, 2024, there are 125 functional CBG plants specifically under the GOBARdhan scheme. Under the SATAT initiative, as of November 30, 2024, 80 CBG plants have been commissioned, with an additional 72 plants currently under various stages of construction. Overall, the CBG industry in India operates with a combined capacity of approximately 1 million kg per day across 150 operational plants as of 2024. The government anticipates commissioning a total of 750 CBG plants by 2028.

Project Implementation Timelines

The timelines for project implementation vary based on plant size:

       Small Plant: Typically requires 6-12 months for implementation.

       Medium Plant: Requires a longer duration of 12-18 months.

       Large Plant: Generally takes 18-24 months for full implementation.

Table 2: Key Progress Indicators and Targets for CBG Development in India


While India has established highly ambitious CBG targets, the actual pace of commissioning has been slower than initial projections. The initial SATAT target of 5,000 plants by 2023 was highly ambitious, and the current number of commissioned plants is significantly lower. However, the government has subsequently introduced new facilitating schemes and adjusted future targets, indicating a learning curve. This demonstrates an adaptive policy evolution. The government's willingness to recalibrate targets and introduce targeted support mechanisms, such as the Biomass Aggregation Machinery (BAM) scheme and the Pipeline Infrastructure (DPI) scheme, illustrates a pragmatic approach to overcoming implementation challenges and ensuring the long-term viability of the sector. The phased mandatory blending obligation is a testament to the government's commitment to creating a sustainable demand for CBG, which is crucial for attracting further investment and scaling up production.

VII. Conclusion

India's commitment to developing a robust Compressed Biogas (CBG) ecosystem is evident through a comprehensive and evolving policy framework, substantial financial incentives, and strategic market integration initiatives. The central government, primarily through the SATAT, GOBARdhan, and MNRE Bio-Energy programs, has laid a strong foundation by ensuring assured off-take, providing capital subsidies, and promoting waste-to-wealth conversion. The introduction of the Biomass Aggregation Machinery (BAM) scheme and the Scheme for Development of Pipeline Infrastructure (DPI) directly addresses critical supply chain and infrastructure bottlenecks, demonstrating a holistic understanding of the sector's needs. Furthermore, the phased implementation of the Compressed Biogas Blending Obligation (CBO) is a transformative step, creating a guaranteed demand that is essential for attracting large-scale private investment and ensuring long-term market stability.

Complementing these central efforts, various state governments have introduced tailored biofuel policies, offering a diverse array of incentives such as capital and operational subsidies, exemptions from duties and charges, and support for feedstock aggregation and bio-manure promotion. This state-level customization allows for targeted development based on regional feedstock availability and economic priorities, fostering a competitive environment that benefits the overall growth of the CBG industry. The deep integration of CBG initiatives within the Swachh Bharat Mission highlights a synergistic approach to addressing both waste management challenges and renewable energy generation, with the Indore Bio-CNG plant serving as a successful model for urban waste-to-energy conversion.

While significant progress has been made, with a notable increase in functional CBG plants and a clear roadmap for mandatory blending, the sector continues to face challenges related to the high initial capital expenditure, the need for efficient feedstock logistics, and the complexities of regulatory clearances. The proposed tax benefits and carbon credit mechanisms, if fully implemented, could further enhance the financial viability and global competitiveness of CBG production. The adaptive nature of India's policies, as seen in the recalibration of targets and the introduction of new support schemes, suggests a proactive stance towards overcoming these hurdles. The continued success of the CBG sector will depend on sustained policy coherence, effective inter-ministerial and inter-state coordination, and increased private sector participation, ultimately contributing significantly to India's energy security, environmental sustainability, and circular economy goals.
