  From this holistic review, recent progress in sorption DAC with CO2 utilization is closely examined. By using favourable sorbents for DAC that combine working processes, capturing CO2 directly from air can slow down global warming with a significant amount of CO2 product to be utilized. Further conversion of captured CO2, TEA and LCA researches are also summarized. The latest developments and some key remarks are discussed as follows. 1. The choice of sorbents for DAC always focuses on indicators, e.g., adsorption capacity, regeneration energy, working temperature, gas selectivity, cost, thermal and chemical stability, etc. Amongst solid sorbents, zeolites and amine modified materials are currently proposed to be the most appropriate candidates for practical DAC applications. Future research on adsorbents could focus on CO2 and H2O co- adsorption mechanism to develop the next generation materials by balancing energy penalty, cyclic performance and cost. For large DAC applications using liquid absorbents, the main barriers of high regen- eration energy and oxidative degradation need to be overcome. Further investigation could be focused on water-lean or water-free absorbent for the improved working performance. 2. After selecting sorption materials, it is essential to determine an appropriate working process that fulfils the excellent performance of DAC. Compared with PSA or VSA that is beneficial for flue gas carbon capture, TSA is a good candidate for DAC which can also be integrated with renewable heat source. Moreover, TVSA is currently the most suitable in applications that require almost pure CO2, e.g., synthesis processes where raw gas has high purity. Besides, TVSA reduces regeneration temperature and vacuum pressure which could prevent degradation, reduce energy demand and increase energy efficiency. For chemical absorption, the BPMED process is recommended which shows great potential of working efficiency by integrating renewable energy. 3. Carbon conversion technologies that require the feedstock with L. Jiang et al.

  Traditional CCS technologies have limitations, such as high energy penalty and secondary pollution. Solid sorbents require further development to achieve high CO2 capture performance and selectivity. The need for efficient, cost-effective, and environmentally benign technologies for CO2 capture and storage remains a significant research gap.
