OUR SOLUTION
Direct Air Capture (DAC) of carbon dioxide is not a new idea, but the x/44 approach is. Instead of relying on energy-intensive thermal reactions to capture COâ‚‚ from the atmosphere, our solution employs an electrochemical process, which yields the same product at a much lower price, energy, and carbon intensity.
Growing the Potential of DAC
x/44 has developed a novel approach that is not energy intensive and can be used in partnership with carbon removal and storage technologies - from large concrete plants in urban areas to novel ocean mineralization facilities. Most other DAC companies require a large upfront investment in equipment, need a lot of physical space, utilize too much energy, and require harsh ecologically unsafe chemicals. x/44 will make it possible for nearly any organization to capture historical carbon dioxide emissions, affordably and sustainably.
The Electrochemical Difference
The x/44 solution introduces a different approach to DAC - Electrochemical Fractional Enrichment: eFCE. Electrochemically driven pH swing adsorption/desorption processes can produce partially concentrated COâ‚‚ streams from air using renewable energy at low energy intensities. This will enable wider spread use of both DAC and alternative COâ‚‚ utilization/abatement technologies. The four key benefits of the x/44 approach are:
Reduced electricity
A novel electrochemical reactor uses water electrolysis to generate acid and base to facilitate a pH swing while generating Hâ‚‚ as a co-product, allowing for DAC at a net energy intensity that is at least two times lower than existing approaches.
1
Sustainable process, end-to-end
Electrochemical cells drive a pH shift to regenerate COâ‚‚-rich solvents rapidly and efficiently while re-circulating charge balancing salts.
2
Modular scale up
3
Durable, readily replicable, and energy-efficient modular electrochemical reactors that are “rackable and stackable” such that overall scaling in system size is achieved by adding units rather than building larger plants.
Enables downstream capture technologies
4
Enhances alternative COâ‚‚ utilization and abatement technologies by providing distributed and flexible access to partially enriched/concentrated COâ‚‚ (5-to-99 vol.% COâ‚‚ ), which allows spatial decoupling from point-sources of COâ‚‚ emission.
