Invention Reference Number
This innovative technology captures atmospheric carbon dioxide (CO2) using a guanidine photobase and small peptide, activated by UV light. The process enables CO2 to be captured and released by cycling light exposure, reducing the need for energy-intensive thermal processes. This photochemically controlled direct air capture method offers a sustainable, low-energy alternative for CO2 capture and release, potentially revolutionizing how industries approach carbon management.
Description
In response to the growing need for sustainable methods to reduce atmospheric CO2, this invention leverages a photobase that becomes more basic when exposed to UV light. The pH shift activates a small peptide that captures CO2 from the air. Once the UV light is removed, the captured CO2 is released, allowing the process to be repeated. This light-activated system avoids the traditional energy-intensive methods, such as thermal stripping, offering a low-cost, scalable solution for carbon capture that can be powered by solar energy. This technology holds promise for large-scale applications in reducing atmospheric carbon.
Benefits
- Sustainable and renewable: Can be powered by sunlight, providing an eco-friendly alternative to conventional carbon capture methods.
- Cost-effective: Eliminates the need for high-energy thermal processes, making it an economical option for direct air capture.
- Scalable for large applications: The technology is suitable for integration into industrial-scale CO2 capture systems.
Applications and Industries
- Direct air capture (DAC): Can be used for removing CO2 from the atmosphere in both small and large-scale operations.
