The enhance weather and ocean alkalinization system increases the dissolution of olivine and mine tailings to escalate ocean alkalinity, this increments CO2 atmospheric absorption. A single system dissolves 4-6 tones of mineral in 2-3 days. Our main component, “The tumbler” creates the perfect environment to maximize mineral dissolution, shrinking from years to days the process of enhance weathering. A technology with multiple applications (ocean, rivers, dams, and land), with a single energy source, cost efficient, and with the ability to deploy anywhere in the world. Our solution sequestrates CO2 naturally in the ocean floors for 100+ years and lower the ocean acidity in the process.
Our river and dam approach uses river currents as its main source of energy and allows the system to be deploy closer to mines than ever before. Our land system can run with a single ECM motor ensuring minimum carbon foot print in the operation system. Furthermore, pulverized silicate rock on land maximizes its CO2 sequestration capacity by increasing its surface area for enhance weathering, this also stimulate plants growth by +15%. In conclusion, our technology is a solution that works with nature to maximize its potential without creating more problems in the process.
Enhance silicate weathering (ESW) is a NET approach in with the natural process of (silicate) rock weathering is artificially stimulated. The technique has been recognized as a promising strategy for atmospheric CO2 removal while counteracting ocean acidification. The implementation of ESW requires suitable source rock to be mined, ground to small grains sizes, and subsequently spread over suitable area. The mineral grains dissolve (chemical weathering), through which CO2 is captured from the atmosphere. Olivine (Mg2-xFexSiO4) is an abundant and fast-weathering ultramafic silica mineral and has been advanced as prime candidate mineral for ESW application. The dissolution of olivine in an aqueous environment consumes protons or equally increases alkalinity, and so increases CO2 uptake by the aqueous medium. ESW can be applied in terrestrial soils, in the surface mixed layers of the open ocean, or by spreading minerals onto sediments of the coastal zone and continental shelf. The largest application domain for ESW would be the open ocean, our technology mills the olivine particles with minimum energy to very small sizes to facilitate dissolution in the surface ocean.
