Adsorption CO2 capture technology has been regarded as one of the most promising approaches for effectively mitigating greenhouse gas (GHG), by which global warming could be controlled as well. The Intergovernmental Panel on Climate Change (IPCC) reported that the temperature increases should be kept within 1.5 °C other than 2 °C, implying that some more typical negative-emissions technologies (NETs) should be intensively investigated, such as the biomass-derived CO2 adsorption process driven by solar thermal energy. In this review, for the post-combustion CO2 capture, the biomass-derived CO2 temperature swing adsorption (TSA) combining the potential of low-grade thermal energy utilization was primarily addressed. In terms of adsorbent, adsorber, and adsorption process, the biomass-derived CO2 adsorption capture was reviewed as the main guideline to achieve the negative-emissions targets. The development of high-performance biomass-derived CO2 adsorbent was investigated firstly, including the thermo-chemical conversion techniques, activation treatment, and surface modification. Biomass-derived CO2 adsorption technology could be verified as one cost-effective and environment-friendly method for alleviating climate change. From the view of heat and mass transfer, the design and optimization of CO2 adsorber were also reviewed for high-efficiently achieving biomass-derived CO2 capture process. Thirdly, the system design for the entire process was discussed from the thermodynamics view, suggesting that the biomass-derived CO2 adsorption capture driven by low-grade solar thermal energy could become more preferable and feasible for commercial-scale application. Finally, concluding remarks and future perspectives for biomass-derived CO2 adsorption capture were addressed. •Development of biomass-based CO2 adsorbent for achieving negative CO2 emission.•Application potential of adsorption reactor and process configuration.•Solar thermal energy supply to enhance the negative-emission effect.•The possible thermodynamics evaluation approaches for the integrated system.
