What is USD 0.65–1.15 per GGE?
The range USD 0.65 to 1.15 per Gallon Gasoline Equivalent (GGE) is an indicative international benchmark for the production cost of compressed biogas or renewable natural gas, drawn from US and European reference projects and used to compare CBG cost-competitiveness against fossil CNG. At a typical conversion of 1 GGE ≈ 2.57 kg of pure methane CBG, this corresponds to roughly USD 0.25-0.45 per kg or ₹21-38 per kg of CBG at current exchange rates.
The wide range reflects four cost drivers. Feedstock type: landfill gas at the low end of $0.50-0.80/GGE because the feedstock is free or negative-cost; dairy manure $0.80-1.10/GGE; agricultural residue with collection logistics $1.00-1.40/GGE; energy crops well above $1.50/GGE. Plant scale: large plants of 10,000+ scfm enjoy economies of scale that smaller plants miss by 25-40%. Upgrading technology: membrane and water scrubbing at the low end, amine and PSA in the middle, cryogenic at the high end. Country and labour cost: US Midwest plants run cheaper than European; Indian production at scale benefits from low labour and civil costs but pays a premium for imported upgrading equipment.
For Indian developers the US benchmark range overlaps the Indian production cost band of ₹35-50 per kg of CBG (approximately USD 0.42-0.60 per kg or $1.10-1.55/GGE). India sits at the higher end of the international range largely because of feedstock-collection logistics, smaller average plant scale (5 TPD versus 50+ TPD US norms), and equipment-import costs offsetting the labour-cost advantage. The good news is that scale-up to 15-25 TPD plants, captive renewable power, and digestate monetisation under PM PRANAM are all closing the gap.
The benchmark should be read as scale-setting context, not as a target. A plant claiming production cost at USD 0.65/GGE in India would need either negative-cost feedstock, scale above 25 TPD, or upgrading technology more efficient than current standards. Sub-USD 1.00/GGE Indian production today is achievable at large scale; below $0.85 is the frontier; below $0.70 is not realistic with current feedstock supply chains.
