Vaulted Deep, a startup focused on biomass carbon removal and storage (BiCRS), has raised $32 million in a Series A funding round to enhance its capacity for durable carbon dioxide removal (CDR) through the geologic sequestration of carbon-rich organic waste.
Founded in 2023 as a spin-off from Advantek, Vaulted Deep aims to sequester organic waste materials, such as biosolids, manure, agricultural residues, and food waste. The company converts these materials into a carbon-rich slurry, which is injected deep underground for permanent storage, preventing the release of carbon dioxide (CO₂) into the atmosphere. This innovative process allows for CO₂ absorption via biomass, which would otherwise contribute to greenhouse gas emissions.
With existing well infrastructure and expertise from Advantek, Vaulted Deep emphasizes scalability, supported by the abundant availability of organic waste. Since its founding, the company has already removed over 7,000 tonnes of CO₂ and recently secured a $58 million offtake agreement with Frontier, committing to remove 152,480 tonnes of CO₂ through 2027 for clients like Stripe and JPMorgan Chase.
The new capital will facilitate the development of additional injection well sites, including a planned facility called Monarch Fields in the United States.
Julia Reichelstein, Co-Founder and CEO, noted the importance of rapid scalability in the CDR sector, while Omar Abou Sayed, Executive Chairman, cited the company’s long-standing expertise in industrial waste management as key to expanding operations.
The funding round was led by Prelude Ventures, with participation from existing investors Lowercarbon Capital, Earthshot Ventures, WovenEarth Ventures, and new investors Fall Line Capital and Rethink Impact. Matt Eggers, Managing Partner at Prelude Ventures, highlighted Vaulted Deep’s potential to significantly impact durable carbon removal at scale.
