Co-benefits and trade-offs of bioenergy with carbon capture and storage - the role of feedstock sustainability

具有碳捕获和储存的生物能源（BECCS）是一种关键的温室气体去除选项，许多综合评估模型结果提出，以帮助在未来世纪实现负排放，以抵消“难以减少”部门的剩余排放-以实现苏格兰和英国承诺的净零排放目标（Smith等人，2016）。提供生物质能和生物燃料化学服务的关键挑战之一涉及生物质原料和该原料供应链的可持续性。这个项目正好解决了这个问题。不同生物能源原料供应链的可持续性特征是什么？如何选择和优化它们，不仅对生态系统服务和联合国可持续发展目标（SDG;最小化权衡）造成最小伤害，而且它们如何做出积极贡献（最大化共同利益和协同作用）？在Smith等人（2019）和Albanito等人的工作基础上，（2019年），该项目的工作将涉及使用欧洲最大的生物质燃料发电站Drax的数据，以研究生物质供应链各个阶段对生态系统服务和联合国可持续发展目标的影响，并通过对实际和替代供应链的建模来量化可能的影响。研究结果还将用于帮助为行业提供信息和完善生物质供应可持续性标准，以帮助获取BECCS的好处，同时提供最佳的环境和社会成果。学生将接受定量数据分析、统计学、生命周期评估和数学建模方面的培训。等，2019年。英国国内生物质生产集中式与分布式生物质能转换和控制系统的缓解潜力和环境影响。Global Change Biology Bioenergy（early online）.Smith，P. et al. 2016.负二氧化碳排放的生物物理和经济限制。Nature Climate Change 6，42- 50.

Bioenergy with carbon capture and storage (BECCS) is a key greenhouse gas removal option, proposed by many integrated assessment model outcomes to help achieve negative emissions in the coming century to offset residual emissions in "difficult-to-abate" sectors - in order to meet net zero emissions targets to which Scotland and the UK are committed (Smith et al., 2016). One of the critical challenges to delivering BECCS relates to the sustainability of the biomass feedstock and the supply chains for that feedstock. This project addresses exactly this issue. What is the sustainability profile of different bioenergy feedstock supply chains - and how can they be selected and optimise to not only do least harm to ecosystem services and the UN sustainable development goals (SDGs; minimise trade-offs), but how could they contribute positively (maximise co-benefits and synergies)? Building on the work of Smith et al. (2019) and Albanito et al., (2019), the work in this project will involve using data from Drax, Europe's largest biomass-fuel power station, to examine impacts on ecosystem services and the UN SDGs of various stages of the biomass supply chain - and to quantify likely impacts through modelling of actual and alternative supply chains. The findings will also be used to help inform and refine biomass supply sustainability criteria for the industry, to help capture the benefits of BECCS while also delivering the best environmental and societal outcomes. The student will be trained in quantitative data analysis, statistics, life cycle assessment and mathematical modelling.Albanito, F. et al. 2019.
