India's GOBARdhan CBG scheme: blending mandate, subsidies, and the road to 5% compressed biogas

India has approved a major expansion of its compressed biogas (CBG) sector under the GOBARdhan scheme, with about Rs 23,731 crore in planned support. The policy pairs capital subsidies for CBG plants with a blending mandate that requires city gas distributors to mix CBG into their natural gas networks, starting at 1% and rising to 5% by FY 2028-29. That mandatory offtake is the key change for developers, because it creates a predictable buyer for the gas. The scheme also covers pipeline connections, biomass aggregation equipment, and a credit guarantee that can absorb up to 85% of default risk for small and medium enterprises. India is targeting a tenfold increase in CBG output, which could displace 10 million tonnes of fossil fuels and cut more than 40 million tonnes of CO2e per year, according to the article. The biggest open question is feedstock logistics, since agricultural residue and municipal waste are seasonal and spread out. If the aggregation network works, the model could scale beyond India.

Useful breakdown of India's CBG push. The blending mandate is the part that actually changes project finance, guaranteed buyers make debt easier to raise. What's missing is current capacity, so 'tenfold' is hard to size. If India starts from a small base, the near-term emissions impact is modest even if the direction is right.

Pipeline subsidy is the detail that matters. CBG plants need a way to reach a trunk line, and India's gas grid is thin outside big cities. I would want to see which clusters are connected before calling this a revolution. Feedstock is seasonal too, stubble does not arrive evenly, so storage and aggregation will decide real utilization.

Blending obligation is the right tool, but enforcement decides whether it works. If city gas companies face no real penalty for missing the blend, the 1% to 5% ramp stays on paper. Also worth tracking who gets the subsidies. Small plants and women-led enterprises are mentioned, yet the capital subsidy structure can still favor larger operators.

The 40 million tonne CO2e reduction number depends on methane leakage and on what the CBG actually replaces. Poorly managed anaerobic digestion can leak methane, which is worse than CO2 over the short term. Turning stubble into fuel is still better than burning it in fields, but verification needs to be part of the scheme.

Good overview of India's CBG plans. The import substitution figure assumes CBG displaces imported gas at scale, and the blending mandate helps with that. Biomass supply chains remain the weak point, they are dispersed and seasonal. If aggregation works, this becomes a useful model for other agricultural economies.
