The Solution CO2LOC a coherent two-part (materials production + CO2 sequestration) market-driven solution to CO2 emissions reduction. Stage 1) Materials production process, in which suitable mineral/waste feedstock is converted to magnesium hydroxide, this first part of the process is expected to be done in bulk at the mine/waste site but could be integrated with the second CO2 sequestration part of the process): 1st step: The process reacts concentrated alkali with olivine (or other Mg-silicate mineral feedstock) at low temperature for short times. The Mg-content of olivine is converted directly to fine Mg(OH)2 (brucite) powder. The other product of reaction is a soluble alkali silicate. Insoluble Mg(OH)2 powder is separated from the alkali silicate solution. 2nd step: Amorphous silica powder is precipitated from alkaline silicate solution. The Alkali is recovered & recycled and Metals recovery takes place. Stage 2) CO2 sequestration & carbonate production process, located where CO2 needs to be sequestered or where carbonate products need to be produced. Low-carbon magnesium hydroxide from the first process is used (as solid or aqueous slurry) to strip CO2 directly from flue gas (or even from air) to permanently sequester CO2 in the form of solid magnesium carbonate powders which can be used in construction materials.
CCC’s CO2LOC technology offers cost effective CO2 capture and utilisation from any CO2 source, including air, whilst producing zero emissions battery metals, silica and magnesium carbonate construction materials. Revenues from co-products are likely to be greater than capture costs, enabling commercially sustainable operations and good returns on investment. The Problem This technology addresses several issues simultaneously. • Low-cost carbon capture for high emissions industries. • Solutions for industries a distance from planned CCS infrastructure. • Also removes NOx, SOx and H2S. • Economic CO2 capture directly from air. • Zero emissions construction materials manufacture. • Zero emissions silica manufacture.
