About this opportunity
The Department of Energy has published a Special Notice for a licensing opportunity regarding a technology for the catalytic regeneration of amino acid-based solvents used in direct air carbon capture (DAC). This technology aims to address the high energy requirements associated with solvent regeneration, which is a major obstacle to the commercialization and large-scale deployment of absorptive carbon capture plants.
The purpose of this Special Notice is to license a technology that utilizes a titanium dioxide catalyst to decrease the solvent regeneration temperature and energy requirements for the potassium sarcosinate (K-sar) solvent used in carbon dioxide DAC. The technology can reduce the regeneration temperature from the usual 120-140°C to less than 100°C, while also increasing the carbon dioxide removal rate by up to 128% and decreasing the energy required for regeneration columns by up to 50%. This technology is open for licensing, and interested parties are encouraged to contact the Department of Energy by October 26, 2024 to learn more about the opportunity.
Notice text
Invention Reference Number: 202405582
Regeneration of solvents used for carbon dioxide capture requires high temperature and high energy, which is a roadblock to commercialization and large-scale deployment of absorptive carbon capture plants. This technology decreases solvent regeneration energy and temperature with the use of a catalyst. It incorporates ways of introducing catalysts into traditional packing elements which will enable their usage directly into conventional regeneration columns.
Description
A major obstacle to solvent-based carbon capture is the amount of energy required for solvent regeneration, which could consume up to 70% of the total operating cost. This invention describes an energy-efficient carbon dioxide regeneration process for amino acid-based solvents used in carbon dioxide direct air capture (DAC) based on a titanium dioxide catalyst for regeneration of aqueous potassium sarcosinate (K-sar) solvent. K-sar is an environmentally friendly amino acid-based solvent that provides fast absorption and high capacity for carbon dioxide. The regeneration temperature can be decreased from the usual 120°C-140°C requirement to less than a 100°C when a catalyst is used. The TiO2 catalyst is thermally stable and when used with the K-sar solvent it can increase carbon dioxide removal by up to 128 percent. Furthermore, this technology increases the carbon capture rate and decreases the energy required for regeneration columns by up to 50 percent, which significantly reduces the carbon capture cost.
Benefits
- Reduces solvent regeneration energy
- Increases overall carbon dioxide capture rates
- Decreases costs
Applications and Industries
- Carbon capture plants
