Houston-based Vaulted Deep takes carbon-rich waste from landfills, feedlots, paper mills and other industrial facilities and converts it to biomass to be buried underground. It says its process can sequester carbon for more than 10,000 years.

The Frontier coalition of tech and corporate heavyweights agreed to pay the year-old company $58.3 million for carbon removal credits generated from its process. The capital will help Vaulted Deep launch commercial-scale production and remove more than 150,000 tons of CO2 by 2027, including more than 18,000 tons this year.

Companies in the Frontier network, including Stripe, Meta and Alphabet, will use the credits to offset their hard-to-abate carbon emissions. 

Carbon removal

Credits generated by removing carbon from the atmosphere are considered higher quality than credits from “avoided” emissions. They’re also in shorter supply.

Frontier has pledged to spend $1 billion on permanent removals by 2030. The corporate network recently bought its first batch of credits from Houston-based Mati Carbon, which uses “enhanced rock weathering” to sequester carbon underground. Mati Carbon’s credit sales are helping farmers in India boost incomes and soil health.
