Frontier has committed $1.75 million to purchase carbon credits from three early-stage companies focused on different carbon dioxide removal (CDR) approaches.
In its fifth round of prepurchases, Frontier is providing financial support to Karbonetiq, Limenet, and pHathom, three startups centered around ocean alkalinity enhancement and surficial mineralization.
The purchases were made on behalf of Google, Stripe, Shopify, and other companies part of the Frontier advance market commitment that aims to catalyze demand and spur growth for permanent carbon removal solutions.
These deals with Frontier mark the first-ever customers for two of the selected CDR providers, and the emerging companies will use the funding to boost their manpower and raise additional support while working on getting their technologies off the ground.
Based in Santa Barbara, California, Karbonetiq tackles CO2 emissions through surficial mineralization—a process powered by alkaline industrial residues that naturally absorb carbon dioxide from the atmosphere.
The residues are then put through a passive aeration system, which is equipped with real-time sensors and software to quantify the captured CO2.
As explained by Karbonetiq, their CDR system can be deployed at existing industrial infrastructures, reducing land requirements while offering improved mineralization rates.
Italy-based Limenet, on the other hand, has come up with a way to produce zero-carbon quicklime—a material used as feedstock in a number of CDR approaches, including ocean liming, surficial mineralization, and mineral looping DAC.
This innovation, enabled through the company’s custom-made kiln, paves the way for multiple decarbonization pathways, from industrial applications to advanced CDR systems.

Positioned in Nova Scotia, Canada, pHathom captures CO2 from coastal bioenergy plants with the help of a weathering reactor that uses limestone, seawater, and biocatalysts to create bicarbonate.
By getting safely released into ocean water, this solution presents an alternative for geologic carbon storage for coastal deployments of DAC, BECCS, and CCS, showing great scaling potential.
As part of the recently announced purchasing round, Frontier will receive 2,142 tons of CDR from Karbonetiq, 510 tons from pHathom, and 330 tons from Limenet.
