About the Project

Severe global warming caused by an unprecedented increase in CO2 concentration in the atmosphere has led to natural disasters such as glaciers melting, intensified heat waves, droughts and floods. It is critical to limit the global temperature rise to 1.5 oC above the pre-industrial level to avoid rapid irreversible damage to the climate. To achieve this, it is necessary to deploy negative emissions technologies (NET) such as the removal of CO2 from ambient air. Direct air capture (DAC) has the ideal advantage of flexible applications, limited land and water footprints and is less prone to contaminants such as SO2 and NOx. However, DAC technology faces challenges of high energy consumption and high cost. Its thermal and electricity consumption can be 2 – 4 times larger than the conventional CO2 capture technology. The electricity and thermal energy in the current DAC design are supplied by fossil fuels such as natural gas. A study has shown that this could lead to 0.48 Mt-CO2/year of additional onsite CO2 emissions when capturing 1 Mt-CO2/year. Therefore there is a need to consider a low-emission energy source (e.g. solar, wind ) for DAC to be truly NET. This project aims to develop an energy-efficient and economically viable renewable energy-driven DAC and CO2 utilisation.
