Direct Air Capture of carbon dioxide is a proven means for companies to reach their net-zero goals, by using a carbon removal mechanism or by switching to more sustainable operations by using fossil-free CO₂ as a feedstock.
Our carbon removal technology is energy-efficient, and that’s how we can provide greenhouses with cheaper CO₂ than they’re paying now. We are determined to make a breakthrough in the field of Direct Air Capture of CO₂.
Carbominer’s capture efficiency relies on several engineering innovations. Our tech uses a combination of dry and wet approaches at the capture stage and electrochemistry-based pH-swing for CO₂ release at the regeneration stage.
Carbominer’s main competitive advantages are the transportability of the capturing modules and a built-in ability to harness intermittent renewable energy.
We believe that the key element on the path to gigaton scale capture is the lowest possible cost per CO₂ ton.
To ensure further cost reductions, we have introduced a passive air contactor to support the work of fans in our capturing units. This innovation is a wind capture tower, and in windy enough locations it could potentially reduce fans’ power consumption to zero.
Another important feature of the tower is dust mitigation, as the amount of dust particles at height is times lower than at the ground level.
Combination of the two well-known capture technologies in one process.
The pH-swing-based regeneration allows us using intermittent renewable energy.
We developed a wind capture tower for obtaining a passive air stream for DAC.
Carbon dioxide direct air capture (DAC) is a rather novel concept, only suggested in 1999 and still in development. Several industrial-scale pilot plants are in operation or planning across Europe and the US. However, large-scale DAC deployment is likely to get policy incentives, as it is not yet profitable on its own.
There are two well-known DAC approaches:
Carbominer’s technology capture efficiency relies on several engineering innovations.
Our technology uses a mix of dry and wet CO2 capture approaches using ion-exchange fiber sorbent at the capture stage and electrochemistry-based pH-swing at the regeneration stage.
As a result, we are releasing almost pure CO2 as output, while keeping our regeneration energy budget low.
The target capture capacity of one Carbominer’s DAC module (1 capturing unit + 1 regeneration unit) is 46 tons per year.
First, we build CO₂ capture modular unit and install it near the greenhouse and start capturing CO₂ from the ambient air. And then we deliver the CO₂ captured to the greenhouse, thus helping to promote the plants’ growth.
Humans have permanently cut down trees both legally and illegally. Thus, it is risky to rely only on planting more trees to remove CO₂ from the air.
With the current amount of pollutants emitting carbon dioxide into the atmosphere, our planet needs both planting trees and carbon-removing technologies.
Though, we do need activism in that area too. If done well, reforestation reduces soil erosion and increases biodiversity, additionally removing carbon dioxide from the ambient air.
