Worked investment case

Biochar: attractive carbon physics, conditional export bankability.

The commercial thesis can work: locally available residue, measurable conversion, durable storage and premium removal demand. The weak link is not necessarily the technology—it is aligning sector classification, national recognition and an accepted issuance path.

Investment thesis

Five things must be true at once

Feedstock

Long-dated, additional, traceable waste biomass without diversion leakage.

Process

Stable operating yield, metered energy balance and defensible lifecycle emissions.

Storage

Eligible end use, low reversal risk and chain-of-custody through application.

Issuance

A current methodology plus an Indonesian national-recording pathway.

Economics

Carbon margin survives verification, registry, sovereign-fee and price sensitivities.

Method screen

Current biochar pathways are not equally bankable

Verra VM0044 v1.2

Operational

Active for biochar removals from eligible waste biomass at new facilities. Indonesia has an MRA with Verra, making this the clearest current route—subject to exact national procedure.

Verra VM0044↗

Puro Biochar 2025

Unresolved

A mature durable-removal method with strong buyer fit. The precise government status identified an LoI, not a completed MRA; recognition should be a closing condition.

Puro Standard↗

Gold Standard PARC

Draft

Indonesia recognizes Gold Standard at program level, but PARC remained under methodology development at the snapshot date.

Illustrative pre-tax, unlevered USD model. It is deliberately transparent and excludes co-financing, depreciation, working capital, tax and any unconfirmed sovereign levy.

Model discipline

A 0% sovereign charge means “no universal charge identified”, not “government cost cannot arise”. Run 5% and 10% sensitivities before IC approval.

Risk register

What can break the case

Sector ambiguity

High

Obtain written classification before final investment decision.

Program recognition

High

Condition registry spend and offtake delivery on national acceptance.

Feedstock eligibility

High

Audit origin, competing uses, sustainability and chain-of-custody.

Carbon yield

Medium

Run pilot mass balance and conservative stability testing.

Verification capacity

Medium

Pre-engage two LVVs/VVBs with matching national and standard scopes.

Sovereign take

Medium

Model explicit 0/5/10% cases; confirm tariff basis before close.

IC recommendation

A staged commitment protects option value

Stage 01

Diligence sprint

Confirm ministry route, registry recognition, feedstock rights, method eligibility and two verifier options.

Stage 02

Pilot + offtake

Prove mass balance and quality; negotiate an offtake whose claim language matches the export route.

Stage 03

FID gates

Require written approvals, executable carbon rights, fixed EPC case and downside IRR above the hurdle.
