Ocean alkalinity enhancement involves adding alkaline substances—commonly described as *antacids*—such as magnesium hydroxide or quicklime to seawater. This process increases the water’s alkalinity, allowing it to absorb and lock away more CO₂ from the atmosphere in the form of bicarbonates that can remain stable in the ocean for up to 100,000 years. Besides reducing atmospheric CO₂, OAE can help reverse ocean acidification, improving conditions for marine ecosystems like coral reefs and shellfish populations[1][3][4].

Frontier’s $31 million investment builds on an earlier commitment of $1.75 million made in mid-2025, which supported three pioneering startups—Karbonetiq (U.S.), Limenet (Italy), and pHathom (Canada)—working on ocean liming and mineralization technologies to accelerate carbon removal at scale. These startups use fast-dissolving minerals like hydrated quicklime and ultramafic mine tailings to boost alkalinity or mineralize CO₂ directly. The new funding will help overcome key challenges such as producing low-emission quicklime, scaling mineral feedstock processing, and advancing field trials to ensure safe, effective deployment of these methods[1][2].

Frontier’s initiative is backed by major buyers including Stripe, Shopify, and Google, who made early carbon removal prepurchases to accelerate technology validation and deployment. The scale of OAE is potentially vast; some estimates suggest it could remove billions of tons of CO₂ annually if properly scaled, making it one of the largest carbon dioxide removal (CDR) pathways available[1][3].

However, scientists caution that while small-scale tests have shown promise, large-scale ocean alkalinity enhancement requires careful monitoring and rigorous field trials to avoid unintended ecological impacts. The long-term environmental safety and efficiency of these interventions remain areas for ongoing research[3][4].

Frontier's recent $31 million investment in ocean alkalinity boosting antacid technologies to combat CO2 has drawn significant expert interest, highlighting ocean alkalinity enhancement (OAE) as a potentially game-changing carbon removal method. Industry leaders emphasize OAE's vast scale potential—up to 100 gigatons of CO2 removal annually—by adding alkaline minerals such as magnesium hydroxide or quicklime to seawater, which not only locks away carbon but also reverses ocean acidification locally. However, experts caution that while small-scale applications appear safe, comprehensive field trials are essential to validate ecological safety and address bottlenecks like low-emission quicklime production, underlining that the approach is promising but requires careful scaling and monitoring[1]
