← Topaz Solar home · Carbon Credits Programme

VCS · Gold Standard · India CCTS · Article 6.2 (Paris Agreement)

Every plant in the portfolio earns twice: once from its products, once from its carbon.

Topaz Solar projects are engineered so that methane becomes fuel instead of emission, CO₂ becomes dry ice instead of exhaust, and invasive biomass becomes product instead of decay. Each conversion is a registrable carbon asset. Across the portfolio, credit income is treated as upside — never in the bankable base case — which is exactly why lenders and buyers trust the numbers below.

₹50–80 Cr

Mechanisms and expected revenue, plant by plant

ProjectCredit mechanismsExpected carbon revenue
Bokakhat, Assam
Water Hyacinth BioCBG
Methane avoidance (1,200 TPD digested — largest source) · CO₂→dry ice · fossil displacement under NRL's CBO · Ramsar + UNESCO nature-based ecosystem premium (₹1,200–2,000/t vs ₹200–400 generic). Dual VCS + Gold Standard registration.~₹4.6 Cr/yr single-unit indicative · ₹5.20 Cr in Year 1 (credits to ONGC/OIL) · programme trajectory to ₹867 Cr by Year 10 with replication · ₹229 Cr/yr statewide at 50 units
Veppur, Tamil Nadu
Green Hydrogen cum Dry Ice
CCTS certification for biogenic green hydrogen (first-mover) · methane avoidance on 42,000 Nm³/day biogas · 95% CO₂ capture to dry ice (16.1 TPD saved from venting) · grey-hydrogen displacement at CPCL · 15–20% biogenic premium.₹50–80 Cr credit portfolio by Year 5; registered in first operating year, fully monetised at maturity
Palani, Tamil Nadu
CBG cum Dry Ice (MNRE Flagship)
Article 6.2 (Paris Agreement) — India's first CBG plant creditable on both methane and CO₂ capture · 16–25 credits per tonne of CBG · clean 100%-Napier baseline with no contested waste-diversion accounting.~70,000–1,09,000 credits/yr on 4,356 t CBG · ≈₹3.1–4.9 Cr/yr illustrative at the 2023 average price (US$4.73, ₹95/US$)
Kamudhi, Tamil Nadu
Solar-powered CBG + GH₂
Same CBG methane-avoidance and CO₂-capture streams as Palani, amplified by captive solar power (₹2.0–2.5/kWh) that keeps the plant's own scope-2 footprint near zero — maximising net creditable abatement per tonne.Credit lines mirror Palani's per-tonne factors at 15 TPD CBG scale; quantification at DPR stage
Bio-Fertilizer Plant
Veppur / Cuddalore
Avoided emissions from displacing 260 TPD of chemical DAP — synthetic fertiliser production and import shipping are among agriculture's largest embedded carbon sources; digestate-based organics also sequester soil carbon.Methodology under development alongside FCO certification; ₹550 Cr/yr of import displacement is the underlying abatement base
Thoothukudi, Tamil Nadu
Bioethanol cum Bioplastics
Fossil-petrol displacement — every litre of ethanol under the Ethanol Blending Programme replaces imported petrol · biogenic PLA displaces fossil plastics · 85% fermentation CO₂ captured as dry ice · invasive-biomass baseline (Prosopis decay avoided).Displacement volumes: 3,300 t/yr ethanol + 3,300 t/yr PLA + 2,805 t/yr captured CO₂; credit registration planned with OMC offtake agreements

Figures for Bokakhat, Veppur and Palani are from their respective project reports; Kamudhi, Bio-Fertilizer and Thoothukudi credit quantifications are completed at DPR/registration stage. Carbon income is excluded from every project's bankable base case. The full mechanism detail for the three lead projects is on the Yogan Green carbon credits page.
