Background In the wake of the climate crisis, the necessity of removing carbon dioxide (CO2) from the atmosphere is of utmost importance. Current methods for removing CO2 from the atmosphere include Direct Air Capture (DAC) which uses a chemical filter that selectively binds to CO2 molecules. Once captured, the concentrated CO2 stream is then stored...

Background The removal of CO2 from the atmosphere through direct air capture (DAC) can help to stabilize the planet’s climate. There is a need for large-scale negative emission systems as more CO2 will need to be captured and stored in the future. There are existing DAC systems for carbon capture using airflow, which can use large fans to bring...

Background Negative emission technologies, including direct air capture (DAC), are a critical solution needed to reduce carbon emissions and lead to a net-zero scenario. DAC solutions are a viable solution that present many advantages, but generate increased demand for low-cost CO2 sorbents, due to greater amounts of material needed to effectively...

Background Carbon dioxide (CO2) capture technology has the potential to alleviate greenhouse gas emissions and mitigate climate change. There are several types of technology that are currently being used to capture and store CO2 such as Direct Air Capture (DAC), power plants, enhanced rock weathering (ERW), etc. Carbon capture technologies are typically...
