Escalating tensions in West Asia have raised serious concerns about India's energy supply stability.
India imports nearly **85%** of its crude oil and a massive amount of LPG through the **Strait of Hormuz**.
To reduce import dependency and improve energy resilience, India is focusing on **Compressed Biogas (CBG)**.

**Compressed Biogas (CBG)** can strengthen national energy security by offering a reliable domestic alternative to imported crude oil and natural gas.
CBG is produced from organic materials like cattle dung, crop residue, sewage sludge, and food waste, making it chemically identical to **CNG**.
Key schemes like **SATAT**, **GOBARdhan**, and the **National Bioenergy Programme** are driving India's waste-to-energy transition.

Biogas is a renewable fuel created when bacteria break down organic waste without oxygen.
Raw biogas contains roughly **45% to 75%** methane, alongside carbon dioxide and trace gases.
When producers remove carbon dioxide, moisture, and impurities from raw biogas, it becomes **Compressed Biogas (CBG)**.
CBG serves as a direct alternative to **CNG** in transport vehicles, industries, households, and power plants.
The government launched the **SATAT** initiative in **2018** to set up **5,000 plants** across the country.
Progress under SATAT remains slow, with only **132 plants** operational by **June 3, 2026**.
The government introduced mandatory blending targets for CBG in transport **CNG** and domestic **PNG**.
The mandatory blending mandate starts at **1% in FY26** and rises gradually to **5% from FY29**.
Commercial production of CBG in India is still in its infancy despite abundant raw material availability.
Over the last decade, rural programmes helped install around **2.88 lakh** small family-scale biogas units.
Globally, **Europe**, **China**, and the **United States** generate nearly **90%** of all biogas.

The **SATAT** scheme encourages private entrepreneurs to establish CBG plants and sell clean fuel to oil companies.
The **GOBARdhan** scheme provides financial aid up to **₹50 lakh** per district for converting organic waste into clean energy.
Mandatory blending mandates step up CBG integration into city gas distribution systems, reaching **5% from FY29**.
The **National Bioenergy Programme** offers central financial support for setting up waste-to-energy and Bio-CNG projects.
The **Biomass Aggregation Machinery Scheme** has an outlay of **₹564.75 crore** to help producers collect and store farm waste.
The government allocated **₹994.5 crore** for gas grid connections, while **SBM-Urban 2.0** supports municipal biomethanation units.

India imports around **85%** of its crude oil, so replacing fossil fuels with domestic waste reduces foreign import bills.
Because CBG works just like **CNG**, it provides a local fuel shield during global geopolitical crises.
Using renewable CBG lowers greenhouse emissions and advances India toward its target of **net-zero emissions by 2070**.
Converting crop residue into biogas discourages open field burning and protects local air quality.
Biogas plants generate organic manure alongside fuel, creating extra income for farmers and improving soil health.
Decentralized plants ensure clean cooking fuel and power reach remote rural areas, advancing **Atmanirbhar Bharat**.

Setting up CBG plants requires high capital investment, leaving India's capacity at under **1%** of its **87 bcm** annual potential according to the **International Energy Agency (IEA)**.
Banks view CBG units as high-risk investments due to uncertain gas prices and weak markets for organic fertilizer.
Organic waste is widely scattered across rural areas, making feedstock collection, storage, and transport very costly.
Inadequate pipeline networks prevent CBG producers from injecting gas directly into city distribution grids.
Overlapping guidelines across multiple schemes create administrative delays and hinder smooth project monitoring.
Relying heavily on dedicated crops like maize for bioenergy could squeeze agricultural land and threaten food security.

The **Indian Biogas Association (IBA)** recommends establishing a **₹10,000 crore** capital subsidy fund to lower initial project costs.
Regulators should enforce priority sector lending and mandate organic fertilizer blending starting at **1% in 2026-27** up to **10% by 2030**.
Developing district biomass inventories and farmer co-operatives will ensure steady feedstock delivery throughout the year.
Speeding up infrastructure funding will connect isolated CBG plants directly to urban gas distribution pipelines.
Setting up a Unified National Biogas Mission will streamline single-window clearances across ministries.
India should follow **Denmark**'s model by focusing strictly on animal manure and organic waste rather than food crops.

Compressed Biogas can transform India's energy security if the gap between targets and plant commissioning is closed quickly.
Sustained policy support and strong pipeline infrastructure will help CBG create a clean, circular energy economy.
