Reduce India's dependence on fossil fuels by enabling scalable, sustainable energy production from agricultural & organic waste.

Technology

• Process: Fixed-dome digesters + PSA compression; direct injection into pipeline network
• Primary Partner: Chem Process Systems (Ahmedabad); built India’s first Napier-based CBG plant
• Alternates: Praj (IN), Zorg (DE), FirmGreen (US), Shengquan (CN), and others

Feedstock

• Napier Grass: Perennial; 4–6 harvests/year; low water & fertilizer; high energy yield
• Cowdung: Sourced from gaushalas; cleaner use vs. burning; stabilizes their income
• Water Use (per acre/year): Napier ~10 kl vs Rice 850 kl; Sugarcane 1,500 kl

Outputs

• CBG: Sold under 10–15 year fixed contracts (GAIL; also Gujarat Gas/BPCL/IOCL pathways)
• Dry Fertilizer: Meets NPK; export-oriented; higher carbon content
• Liquid Fertilizer: 80–94% recycled; excess sold locally

Carbon Credits

Standard: Gold Standard accreditation in process. Potential: Offsets ~140k TPA; sequestration 30–80k TPA potential (project mix dependent).
