Carbon credits — from ecological liability to financial asset.

Expected revenue

• Single-unit indicative: ~₹4.6 Cr/yr under VCS + Gold Standard — treated strictly as upside, never in the bankable base case.
• Year 1 (2026): ₹5.20 Cr — VCS registration completed and initial credits sold to domestic compliance buyers such as ONGC / OIL.
• Programme trajectory to ₹867 Cr by Year 10 as the 50-unit Assam replication scales, with international buyers entering alongside the domestic compliance market.
• Statewide potential: ₹229 Cr/yr in carbon credits once replication is complete — the financial engine of India's first carbon-positive state.

Why these credits command a premium

• High-integrity methodologies — measurable 1,200 TPD feedstock intake gives auditors a hard, meterable baseline.
• Nature-based co-benefits — 18,000 ha of wetland restored, 17,500 fishing families uplifted: exactly the co-benefit profile Gold Standard prices highest.
• Dual registration — VCS for volume, Gold Standard for premium, sold into whichever market clears higher.

Credit mechanisms

• Methane avoidance — 42,000 Nm³/day of raw biogas that would otherwise be flared or vented at TMB and the Phase 2 digester feedstocks is converted to hydrogen.
• CO₂ capture → dry ice — 95% of process CO₂ (RRSi technology) becomes biogenic dry ice instead of an emission: 16.1 TPD of CO₂ saved from venting daily.
• Grey-hydrogen displacement — every tonne of biogenic H₂ delivered to CPCL displaces SMR-from-natural-gas hydrogen; as CCTS matures, grey-process users face rising liabilities that make green credits more valuable.
• Biogenic premium — India's first biogenic GH₂ commands a 15–20% price premium over electrolysis-based hydrogen in credit and product markets alike.

Expected revenue

• ₹50–80 Cr carbon-credit portfolio by Year 5 — built through early CCTS certification, per the project report.
• Registration in the first operating year — the project timeline registers credits as CPCL supply and SIGHT revenue begin, with full monetisation at maturity.
• Counted within, not on top of, the ₹389 Cr full-scale annual revenue — the project stands on hydrogen and dry ice alone; credits deepen the moat.

What makes Palani distinct

• Dual-stream eligibility — the first CBG project in India creditable for both methane capture and CO₂ capture, because the cryogenic dry-ice unit turns the CO₂ stream into a verified product rather than an emission.
• Clean baseline — 100% self-cultivated Napier feedstock means no contested waste-diversion baseline; the entire gas output is additional.
• Revenue line in the model — carbon credits appear as a standing income line in the project's financial projections alongside CBG, FOM, LFOM and dry ice.

The illustrative range above applies the synopsis's published factors (16–25 credits/t, 2023 average price); actual realisation depends on registration, vintage and market at the time of sale.
