Research progress on biomass ash carbon capture and storage
Carbon capture and storage(CCS)technology is an important way to slow down the continuous increase in atmospheric CO2 concentration and to achieve the dual carbon target.Carbon capture and storage through biomass ash is a secure,permanent,and environment friendly way.To better understand the characteristics of biomass ash carbon capture and storage,we summarized progresses on biomass ash carbon capture and storage,clarified the mechanisms of biomass ash carbon sequestration,analyzed the influencing factors,and explored its applications in various domains.The capacity of CCS by biomass ash mainly derived from alkaline earth metal oxides of CaO and MgO.The actual carbon sequestration efficiency is affected by factors such as biomass source,chemical composi-tion,temperature,humidity,pressure,and CO2 concentration.However,the underlying mechanism is unclear.The CCS capacity of biomass ash significantly impacts its potential applications in building materials reuse,soil quality improvement,and adsorbents carbon capture and storage absorbent preparation.Long-term research is criti-cally needed.For future studies,we should strengthen the research on the carbonization efficiency of biomass ash from multiple sources,establish a database related to the impact of biomass ash carbonization,build a methodologi-cal system to promote scientific management of biomass ash,develop biomass ash carbon capture and storage tech-nologies,and quantitatively assess its role in carbon sequestration.
