V-Grid Energy Systems

Audit Analysis

V-Grid Energy Systems is a US biochar removal project verified by 350Solutions under the Puro standard, with a VVB-confirmed investment additionality test and a 1000-year permanence claim. The project's main weaknesses are the absence of a buffer pool, no quantified leakage treatment, a project-specific baseline, and several material operational findings (including a downward revision of carbon content) that temper confidence in the credit's robustness. Transparency is moderate: claimed and verified ERR figures match exactly at 207, but key MRV parameters such as FNRB and usage rates are not stated in the extracted record.

Project Description

Red Flags

• ⚠No buffer pool is documented for a 1000-year permanence claim, leaving no financial backstop against potential reversal or credit retirement disputes.
• ⚠Leakage deduction is not stated and no justification is provided, despite biochar production involving feedstock sourcing and transport where displacement effects are plausible.
• ⚠Five material findings in the verification report include a downward revision of carbon content from 90.58% to 87.80% and increased shipping distances raising Euse emissions, yet no corrective actions were required.
• ⚠Three contradictions exist between the 2024 verification report and the 2022 methodology/appendix documents on safeguards, additionality test type, and VVB verification status.
