Project Description
Advanced Cooling Technologies Inc. (ACT) and Lehigh University (LU) are developing a novel acid/base ion-exchange direct air capture (DAC) process during this Small Business Technology Transfer (STTR) program. This system is unique because sorbent regeneration can be driven by either a low-grade heat source (industrial waste heat or geothermal) or an electrically derived weak base solution. During Phase I, the project team demonstrated carbon dioxide (CO2) capture rates of greater than 90%, with thermal regeneration of the sorbent occurring at temperatures as low as approximately 50°C. The DAC system uses widely available commercial adsorbent resins, which reduce cost and help alleviate supply constraints. The system design and layout allow it to scale easily and be implemented as a modular system, minimizing manufacturing and deployment costs.
During Phase II, ACT and LU will develop the individual system-level components required for scaling the technology. After demonstrating the operation of these components and sub-systems, an integrated sub-scale test bed will demonstrate system operation across dozens of capture and regeneration cycles. The project team will use the data from these test bed cycles to refine their full-scale system models.
Project Benefits
DAC technologies allow for CO2 removal from current and legacy releases of CO2 in the atmosphere to achieve negative emissions. Initiatives that span from fundamental research in materials and chemical sciences to the continued advancement and field-testing of DAC technologies currently under development target a reduction in the energy consumption and cost of DAC systems while minimizing water and land use. Lab- and bench-scale testing of novel materials applicable to the conditions and process requirements of DAC will validate improved performance over materials currently available for CO2 separation.
