Suppliers

A supplier is an organization focused on achieving carbon dioxide removal (CDR). They can be grouped into pathways based on capture and storage mechanisms. Scientists at Isometric work with multiple suppliers across pathways to advance research and to both review and develop protocols.

DescriptionBiomass Carbon Removal and Storage (BiCRS) involves storing carbon present in biomass, which is organic material originating from living or recently living organisms. Examples of products stored are biomass in its original form, dried biomass, or products produced from biomass such as bio-oil or bio-char.
Vaulted Deep
Vaulted takes biomass and with minimal processing is able to inject it underground for durable storage.
United States
Verification in progressCredits expected Q2 2024
Charm Industrial
Charm Industrial converts agricultural waste biomass into bio-oil via fast pyrolysis, and then injects the bio-oil underground to achieve storage of carbon on geological timescales.
Coming soon
Carba
Carba converts biomass to a stable solid carbon through torrifaction and buries it underground in anoxic chambers for durable storage.

DescriptionEnhanced weathering refers to the acceleration of natural chemical weathering, a process in which CO₂ dissolved in rainwater reacts with minerals contained within rocks, partly dissolving them and producing stable bicarbonate ions. When these bicarbonate ions are transported to the oceans via rivers they may be securely stored on long-term timescales. Typically enhanced weathering involves the spreading of crushed reactive rocks or minerals on croplands.

DescriptionOcean Alkalinity Enhancement (OAE) enhances the natural capacity of the ocean to absorb and store carbon. The process works by adding alkaline materials to seawater, which acts to raise pH and shift the surface ocean’s carbonate buffer system to consist of proportionally more bicarbonate and carbonate ions and less dissolved aqueous carbon dioxide. This change prompts drawdown of atmospheric carbon dioxide into the surface ocean, lowering the concentration of atmospheric carbon dioxide.

Planetary Technologies
Planetary Technologies add alkaline compounds to seawater to enhance the natural ability of seawater to absorb atmospheric carbon dioxide, storing the carbon in dissolved carbon-containing ions in the oceans.
Direct Air Capture
DescriptionDirect air capture refers to a set of chemical or electro-chemical processes that remove carbon dioxide from ambient air. CO₂ in the air binds to either a solid sorbent or a liquid solvent which then undergo a process called regeneration where they are treated to release captured CO₂. This typically creates a pure stream of CO₂ which can then be stored using a variety of storage techniques.

Airhive
Airhive captures carbon dioxide from the air using mineral sorbents through a process known as fluidisation

Carbon Atlantis
Carbon Atlantis is using a process known as electrochemical pH-swing. Their system uses a solvent to capture CO₂ and an acid to release it.
Coming soon
EDAC Labs
EDAC Labs’ electrochemical process allows for the production of low cost acid and base products that are utilized to recover commodities from extractive wastes and capture CO₂.
Direct Ocean Capture
DescriptionDOC is a marine Carbon Dioxide Removal (CDR) technique that involves the removal of CO₂ from seawater, resulting in a pure CO₂ stream which can then be utilized in products, fuels, or stored durably in geological storage reservoirs. The CO₂-depleted seawater produced during the process is then returned to the ocean, where it has an increased capacity for atmospheric CO₂ drawdown due to the resulting pCO₂-deficit.
Coming soon
Captura Corporation
Captura’s Direct Ocean Capture technology extracts CO2 from the upper ocean, creating capacity for the ocean to remove CO2 from atmospheric air.
Electrolytic Marine CO₂ Removal
DescriptionElectrolytic marine carbon removal utilizes the changes in seawater pH that result from water electrolysis to facilitate carbon removal. When sufficient voltage and current are applied to influent seawater, the fluid surrounding the cathode (catholyte) will become alkaline, while the fluid surrounding the anode (anolyte) will become acidic. The resulting catholyte and anolyte are processed separately. Due to the significant pH increase in the catholye, dissolved inorganic carbon (DIC), calcium ions and magnesium ions are quantitative precipitated as carbonate minerals and magnesium hydroxide. Following mineral precipitation, the catholyte is sparged with atmosphere to restore some of the DIC that has been precipitated. The acidic anolyte is separately processed by adding alkaline feedstock to restore some of the alkalinty that was removed in the catholyte. Following processing, the catholyte and the anolyte are mixed and released back into the ocean.
