Carboniferous

Black Sea

Sinks leftover surgar cane and corn fibre into the deep ocean. 

Carboniferous is safely and purposefully replicating the process of anoxic biomass carbon sequestration. We are a BiCRS pathway, storing terrestrial biomass in naturally forming permanent anoxic basins under the ocean.

Vessel Manufacturing Factory

Vessel Manufacturing Factory

Panama City, Panama

Uses solar unmanned vessels to sink invasive seaweed to the deep sea.

Pull To Refresh’s carbon removal solution is highly scalable due to its deployment in the open ocean, which offers abundant space for expansion. This approach is both inexpensive and energy-efficient, utilizing solar power and the natural process of photosynthesis to minimize costs and environmental impact. The carbon is stored for over 1000 years thanks to the deep-sea environment’s cold temperatures, high pressure, and slow-moving horizontal currents. This ensures long-term sequestration.

Banyu Carbon

CoMotion Labs at Fluke Hall, University of Washington

Uses sunlight to degas seawater

Banyu uses sunlight to capture CO₂ from seawater. A reusable, light-activated molecule that becomes acidic when exposed to light causes carbon dissolved in seawater to degas as CO₂, which is then stored permanently. Because only a small portion of the visible light spectrum is needed to trigger the reaction, this is a highly energy-efficient approach to direct ocean removal.

Captura

Kårstøvegen 1, Sekundær Fylkesvei 798, 5565 Tysværvåg, Norway

Uses established electrochemical concepts to enable gigatonne removals

Developed and proven in Caltech’s laboratories, Captura uses established electrochemical concepts to enable gigatonne-scalable solutions for removing carbon dioxide from the atmosphere via direct ocean capture. We capture carbon dioxide using only renewable electricity and ocean water, producing no by-products. Captura’s mission is globally scalable carbon capture to support a sustainable future for the world’s climate.
