44.01 Lands $11.7M Carbon Mineralisation Deal

Frontier has agreed to buy $11.7 million of carbon removal from 44.01, backing a project that turns captured carbon dioxide into stable rock.

What happened

The purchase covers roughly 21,000 tonnes of CO₂ removal expected between 2028 and 2031. 44.01 dissolves captured carbon dioxide in water and injects it into formations rich in peridotite, where the CO₂ reacts with magnesium-bearing minerals and becomes solid carbonate. The initial project will use carbon captured from a wastewater treatment facility in the United Arab Emirates. The deal is a future offtake commitment rather than revenue from completed removals today, and delivery depends on the project reaching operational milestones.

Why it matters

Permanent carbon removal is difficult because stored CO₂ must remain contained for very long periods. Mineralisation offers a potentially durable pathway because the carbon becomes chemically bound in solid material rather than remaining as compressed gas underground. Early purchase agreements can help finance the infrastructure and monitoring needed to prove the process at larger scale.

The bigger picture

The project is small relative to global emissions, but it provides a real commercial test of continuous mineralisation. If costs fall and injection systems scale safely, mineral storage could become one of several durable carbon-removal options alongside direct air capture and biomass-based approaches.
