Fuel cell vehicles, as the most promising clean vehicle technology for the future, represent the major chances for the developing world to avoid high-carbon lock-in in the transportation sector. In this paper, by taking China as an example, the unique advantages for China to deploy fuel cell vehicles are reviewed. Subsequently, this paper analyzes the greenhouse gas (GHG) emissions from 19 fuel cell vehicle utilization pathways by using the life cycle assessment approach. The results show that with the current grid mix in China, hydrogen from water electrolysis has the highest GHG emissions, at 3.10 kgCO2/km, while by-product hydrogen from the chlor-alkali industry has the lowest level, at 0.08 kgCO2/km. Regarding hydrogen storage and transportation, a combination of gas-hydrogen road transportation and single compression in the refueling station has the lowest GHG emissions. Regarding vehicle operation, GHG emissions from indirect methanol fuel cell are proved to be lower than those from direct hydrogen fuel cells. It is recommended that although fuel cell vehicles are promising for the developing world in reducing GHG emissions, the vehicle technology and hydrogen production issues should be well addressed to ensure the life-cycle low-carbon performance.

二氧化碳捕集与封存(CCS)的大规模部署在全球实现净零排放的道路中显得越发紧迫,但CCS的全球部 署显著落后于预期。回顾和学习先进国家CCS的成功实例与历史,有助于包括中国在内的国家采取科 学的方法来推动与部署CCS项目。在CCS关键技术研发与示范中,本文认为先进国家CCS科技基础研 究设施的建立是其CCS技术源头创新、成本降低、风险降低、商业化推广及人才培养的源泉。除了激励 政策外,CCS的良性发展,需要从科技基础研究设施过渡到规模化商业化设施,不然难以跨越从小规模示 范到百万吨级CCS中心(hub)与千万吨级CCS hub实施的技术障碍。CO2地质封存是CCS项目的最终目 标与解决捕集CO2归宿的驱动力。进一步提高观测、监测和证实(MMV)CO2封存量、减排量与安全性技 术的精度,仍然是地质封存面临的问题。咸水层CO2封存可以更好地耦合多种碳排放源,是目前需要优 先发展的方向。降低低浓度CO2捕集的能耗、减小化学吸收剂的衰竭、提高燃烧后CO2捕集系统的运行效率和稳定性成为制约大规模CCS部署的关键。对于各国最大程度地开采化石燃料而不是从环境友好 程度较低的产油国进口石油,CO2驱油提高石油采收率(CO2-EOR)也非常重要。

Waste-to-energy supply chains are important potential contributors to minimising the environmental impacts of municipal solid waste by reducing the amounts of waste sent to landfill, as well as the fossil fuel consumption and environmental footprints. Accounting for the spatial and transport properties of the waste-to-energy supply chains is crucial for understanding the problem and improving the supply chain designs. The most significant challenge is the distributed nature of the waste generation and the household energy demands. The current work proposes concepts and a procedure for targeting the size of the municipal solid waste collection zone as the first step in the waste-to-energy supply chains synthesis. The formulated concepts and the provided case study reveal trends of reducing the net greenhouse gas savings and energy recovery by increasing the collection zone size. Population density has a positive correlation with the greenhouse gas saving and energy recovery performance. For smaller zone size the energy recovery from waste approaches and in some cases may surpass the energy spent on waste transportation. The energy recovery and greenhouse gas savings remain significant even for collection zones as large as 200 km2. The obtained trends are discussed and key directions for future work are proposed.
