Vaulted Deep

Biomass carbon removal via deep injection

Overview

Vaulted Deep provides waste management services and sells permanent carbon removal credits. It uses a proprietary slurry-injection method to bury biomass waste deep underground, turning wastes like biosolids and food waste into a slurry that is injected about a mile down into porous rock layers to achieve long-term storage. The process also prevents methane and other pollutants from being released by landfilling or incineration, and revenue comes from waste disposal fees plus verified carbon credits sold through a large buyer coalition led by Frontier. The company differentiates itself by using Advantek’s decades of oil-and-gas deep-well injection know-how and infrastructure to scale quickly, and its goal is to provide practical, scalable deep-geologic carbon removal that helps customers meet climate targets.
