Planeteers

Planeteers is a startup developing innovative technology for large-scale carbon removal. Our advanced reactor technology accelerates natural limestone weathering to convert COâ‚‚ into mineralized water for safe ocean storage. We aim for rapid carbon capture, scaling significantly by 2030, and targeting a gigaton of COâ‚‚ removal by 2047 to achieve fast, permanent carbon mineralization and ocean storage.

Industry Problem

Planeteers aims to solve the problem of insufficient large-scale carbon removal by accelerating natural processes to capture and permanently store COâ‚‚, addressing the urgent need for effective decarbonization solutions to combat climate change.

R&D Focus

Planeteers focus on developing advanced reactor technology that accelerates natural limestone weathering to capture and convert COâ‚‚ into stable mineralized bicarbonate, which is permanently stored in the ocean. Their niche lies in carbon dioxide removal (CDR) by enhancing natural processes to enable large-scale, rapid, and safe carbon capture from both point sources and the atmosphere, offering a sustainable and effective solution for decarbonization.

Innovative Solution

The Planeteers solution accelerates the natural process of limestone weathering, where atmospheric COâ‚‚ reacts with water and limestone to form bicarbonate, a stable compound naturally stored in oceans for thousands of years. Using their advanced reactor technology, they speed up this reaction from thousands of years to just minutes, converting COâ‚‚ into mineralized water (hydrogen carbonate) that can be safely and permanently stored in the ocean. This approach neutralizes large amounts of carbon dioxide quickly and sustainably, enabling effective carbon removal from both industrial emissions and the atmosphere.

Solution Effectiveness

Planeteers technology has demonstrated rapid carbon capture capabilities, with prototypes progressing from handling over 60 tons of COâ‚‚ in 2023 to plans for industrial units capturing 2,500 tons by 2025, scaling to 10,000 tons by 2026, and targeting a global roll-out of 1 million tons by 2030. Their long-term goal is to achieve a capacity of 1 gigaton of COâ‚‚ removal by 2047, showcasing significant potential to make a large-scale impact on climate change through fast, permanent carbon mineralization and ocean storage.
