Why in the News
Compressed biogas (CBG) producers will now get both capital assistance and a guaranteed buyer from the Centre, with output targeted to rise from 0.4 to 4 to 6 million standard cubic metres per day. The Union Minister of Petroleum and Natural Gas formally launched the ₹23,731 crore GOBARdhan scheme to drive this ten fold increase.
What is compressed biogas, and what does GOBARdhan do with it?
- What CBG is: CBG is methane rich gas made by processing organic waste and compressing it, so it works like CNG but comes from waste rather than gas fields.
- Feedstock: The scheme targets agricultural residue, animal dung, food waste and other biomass.
- Why it was introduced: The government wants to turn agricultural and organic waste into a new source of domestic energy.
- Farmers as suppliers: The Minister said the programme would turn farmers from “Annadatas” (food givers) into “Urjadatas” (energy givers), since their waste becomes saleable fuel input.
- The takeaway: Pairing a plant subsidy with an assured market tackles the two reasons CBG plants have struggled, high upfront cost and uncertain sales.
How is the support structured?
| Component (lifecycle stage) | Support | Main beneficiary | |—|—|—| | Greenfield CBG plants (plant build) | ₹1.25 crore per tonne per day (TPD) of eligible CBG capacity | New CBG producers | | Brownfield capacity (plant expansion) | 50% of the greenfield rate, for capacity added through fresh investment | Plant owners expanding output | | Upgrade of existing biogas plants (asset conversion) | ₹0.60 crore per TPD, with a ₹5 crore project ceiling | Biogas plant operators shifting to CBG | | Assured offtake (offtake and demand) | Up to 100% of eligible output bought at an administered price of ₹2,110 per mmBtu (million British thermal units, a unit of heat energy used to price gas), about ₹98 per kg | All CBG producers |
- Project ceiling: Total capital assistance for one project is capped at ₹30 crore, counted across the scheme’s “two eligible capital-support components”, so large plants cannot draw unlimited subsidy.
- Why offtake matters: The assured offtake is offered to make CBG projects commercially viable, because a plant sure of selling its output at a fixed price can raise loans against that income.
What does the scheme aim to achieve?
- Cleaner energy mix: The output rise is meant to help lift natural gas, a cleaner burning fuel, to a 15% share of the energy basket by 2030.
- Fossil fuel replacement: The scheme aims to replace about 10 million tonnes of fossil fuel with clean gas, cutting over 40 million tonnes of carbon dioxide emissions.
- Organic manure: Plants would also yield around 250 million tonnes of organic manure for farmers as a by product.
- Import savings: Domestic gas would save more than ₹40,000 crore in fuel imports.
Challenges
- Scattered feedstock: Farm residue is seasonal and dispersed, so plants struggle to secure year round supply. Eg. The Sustainable Alternative Towards Affordable Transportation (SATAT) initiative missed its plant target.
- Weak manure market: Organic manure competes with subsidised chemical fertiliser, so a key by product may not sell.
- Grid distance: Plants far from city gas pipelines must truck compressed gas, adding cost.
- Price risk: A fixed administered price can turn into a subsidy burden if imported gas becomes cheaper.
- Operation and maintenance: Small biogas plants often fall idle once technical support ends.
Way Forward
- Feedstock aggregation: Farmer producer organisations should run baling and collection hubs under the crop residue management scheme.
- Manure offtake: Fertiliser companies should co-market fermented organic manure alongside chemical fertilisers.
- Pipeline links: The Petroleum Ministry should fund last mile connections from CBG plants to city gas networks.
- Blending obligation: Enforce the phased CBG Blending Obligation on city gas distribution networks so demand grows with supply.
- Commissioning tracker: Publish plant wise commissioning and output data so slippage shows early.
Conclusion
The scheme turns biogas into an energy security instrument backed by both capital and a guaranteed buyer. Whether plants are actually commissioned and fed with year round feedstock will decide if the output target is met.
Key numbers
- Value added to GDP: over ₹75,000 crore (scheme estimate).
- Jobs: more than 1.5 lakh (scheme estimate).
- Current share of natural gas in the energy basket: 6 to 7%.
