The financing is backed by Vaulted Deep’s existing service agreements and carbon removal offtakes, including contracts with Frontier buyers like Google, Shopify, and Stripe. Having delivered over 20,000 tons of carbon removal in the first half of 2026—surpassing its 2025 total—the company is now scaling its operations to meet rising industrial demand. CEO Julia Reichelstein noted that the capital will accelerate the deployment of the firm’s AI-driven site development platform, which streamlines the complexities of permitting and geological evaluation for new injection sites.
Vaulted Deep Secures $35 Million to Scale Subsurface Waste Infrastructure
A $35 million debt facility from Mediobanca marks a turning point for carbon removal finance, proving that long-term purchase contracts can unlock mainstream capital for physical infrastructure. Arranged by CFP Energy, the deal provides the Houston-based company with the necessary leverage to expand its subsurface waste disposal network nationwide.
This debt infusion complements $48 million in previous equity rounds and an $8 million XPRIZE award. By integrating AI tools to optimize site discovery and monitoring, Vaulted Deep aims to transition from pilot-scale operations to a standardized, high-capacity infrastructure model. The transaction also received a boost from Artio, which provided carbon insurance to de-risk the investment for institutional lenders. As corporate demand for permanent carbon removal grows, this deal signals a shift toward utilizing traditional debt markets to fund the physical assets required for the energy transition.
