The future of the global environment is at threat due to global warming and climate change primarily driven by greenhouse gas emissions. Bioenergy with carbon dioxide capture and storage/utilisation (BECCS/U) through its CO2 negative emission capacity is considered a principal component of global mitigation strategies as agreed in the Paris climate change agreement. In this study, the current global status and efforts to implement BECCS systems are comprehensively reviewed. The potential for thermochemical conversion processes (combustion, gasification, pyrolysis, and liquefaction) to manifest within BECCS systems is analysed, in addition to their integration potential with carbon dioxide capture methods. Outcomes suggest that gasification and combustion processes when integrated with CO2 capture and storage (CCS), within combine heat and power (CHP) configurations, biomass integrated gasification combine cycle (BIGCC) and chemical looping cycle (CLC) are mature technologies. Furthermore, this review indicates that pyrolysis and liquefaction process are commercial and lab-scale respectively. When integrated within BECCS systems, pyrolysis systems are at the pilot level and liquefaction processes are at lab scale. Moreover, a comprehensive discussion on the negative emission potential from various BECCS configurations is provided, highlighting their role in advancing bio-refineries through waste management and conversion to value-added products such as biochar, ethanol, bio diesel etc. The pyrolysis process has CO2 mitigation potential of 2.2 GtCO2/year by 2020-2050. Finally, an insight into the commercial barriers and future perspectives of BECCS technologies, role of international supply chains therein, and the need for effective stakeholder management to facilitate BECCS systems within global trade.

BECCS 网络内与 CO 2捕获和利用相结合的基于生物质的热化学转化技术的全面审查

由于全球变暖和主要由温室气体排放驱动的气候变化,全球环境的未来受到威胁。具有二氧化碳捕获和储存/利用 (BECCS/U) 的生物能源通过其 CO 2负排放能力被认为是巴黎气候变化协议中商定的全球减缓战略的主要组成部分。在这项研究中,全面审查了当前的全球状况和实施 BECCS 系统的努力。分析了热化学转化过程(燃烧、气化、热解和液化)在 BECCS 系统中体现的潜力,以及它们与二氧化碳捕获方法的集成潜力。结果表明,当与 CO 2结合时,气化和燃烧过程在热电联产 (CHP) 配置中,捕获和储存 (CCS)、生物质综合气化联合循环 (BIGCC) 和化学循环循环 (CLC) 是成熟的技术。此外,该评论表明热解和液化过程分别是商业规模和实验室规模。当集成到 BECCS 系统中时,热解系统处于中试水平,液化过程处于实验室规模。此外,还对各种 BECCS 配置的负排放潜力进行了全面讨论,强调了它们在通过废物管理和转化为生物炭、乙醇、生物柴油等增值产品来推进生物炼油厂的作用。热解过程产生 CO 2 2.2 GtCO 2 的减排潜力/年 到 2020-2050 年。最后,深入了解 BECCS 技术的商业壁垒和未来前景、国际供应链在其中的作用,以及有效的利益相关者管理以促进全球贸易中的 BECCS 系统的必要性。
