Frontier commits $1.75 million to ocean liming and surficial mineralisation start-ups

Frontier has committed $1.75 million in carbon removal prepurchases to three early-stage companies: Karbonetiq, Limenet, and pHathom. These purchases, made on behalf of Stripe, Shopify, and Google, support the development of ocean alkalinity enhancement and surficial mineralisation technologies. Karbonetiq received funding for 2,142 tons, Limenet for 330 tons, and pHathom for 510 tons. This initiative marks the first customer for two of the three companies, aiming to accelerate promising but underexplored carbon removal solutions.
