Analysis on carbon emission reduction intensity of fuel cell vehicles from a life-cycle perspective

《能源前沿（英文）》 doi: 10.1007/s11708-023-0909-1

摘要： The hydrogen fuel cell vehicle is rapidly developing in China for carbon reduction and neutrality. This paper evaluated the life-cycle cost and carbon emission of hydrogen energy via lots of field surveys, including hydrogen production and packing in chlor-alkali plants, transport by tube trailers, storage and refueling in hydrogen refueling stations (HRSs), and application for use in two different cities. It also conducted a comparative study for battery electric vehicles (BEVs) and internal combustion engine vehicles (ICEVs). The result indicates that hydrogen fuel cell vehicle (FCV) has the best environmental performance but the highest energy cost. However, a sufficient hydrogen supply can significantly reduce the carbon intensity and FCV energy cost of the current system. The carbon emission for FCV application has the potential to decrease by 73.1% in City A and 43.8% in City B. It only takes 11.0%–20.1% of the BEV emission and 8.2%–9.8% of the ICEV emission. The cost of FCV driving can be reduced by 39.1% in City A. Further improvement can be obtained with an economical and “greener” hydrogen production pathway.

《能源前沿（英文）》 2011年第5卷第2期页码 214-220 doi: 10.1007/s11708-010-0133-7

摘要： The influence of energy intensity on carbon intensity depends upon the fraction of energy mixes with high carbon emissions in the total energy mixes . The correlation of with a variety of primary energy mix fractions and technology advances such as CCS and CCHP is analyzed and deduced. Taking the long-term carbon reduction target in 2050 settled upon by the Copenhagen Agreement and the mid-term target suggested by the “450 Scenes Program” of the International Energy Agency (IEA) as constraints, the new pattern of the energy transition of the world in 2020, 2030, and 2050 are estimated and figured out. The peak value of energy consumption will lag behind the peak value of carbon emissions; the world energy structure shifting point will be in 2020–2025. Estimates show that China’s mid-2020 and long-term targets of energy-saving and emission reduction announced by the Chinese government might be achieved.

《能源前沿（英文）》 2012年第6卷第4期页码 427-435 doi: 10.1007/s11708-012-0199-5

摘要： An energy audit of 22 tertiary hospitals was conducted in Tianjin. The detailed content included design data, basic information, energy bills and equipment lists. It was shown that during the study, the energy intensity of hospitals in Tianjin was approximately stable and the average level of energy consumption was 348 kW·h/(m ·a). From the date collected, it was calculated that the energy intensity of general hospitals was 380 kW·h/(m ·a), and the average carbon emissions was 157 kgCO /(m ·a); While the energy intensity of specialized hospitals was 309 kW·h/(m ·a), and the average carbon emissions was 131 kgCO /(m ·a). By breaking the energy consumption down into several items, it was found that the heating system consumed the highest amount of energy (42.12%), followed by the cooling system (6.78%), the medical equipment (4.98%) and the lighting system (3.63%). The main factors that affect the hospital energy consumption were determined, and some feasible technology and management measures to save energy and reduce carbon emissions were proposed.

《中国工程科学》 2023年第25卷第2期页码 187-197 doi: 10.15302/J-SSCAE-2023.02.016

摘要：

隐含碳排放限值是建筑结构碳排放量化调控与减碳目标保障的关键指标。本文从社会“碳中和”所需减碳路径出发，依据建筑结构保有与需求量中的新建与既有结构构成比例，提出减碳目标分解方法，为既有结构低碳维护与新建结构低碳设计提供与宏观年度减碳需求相匹配的限值预设依据。依托“双碳”目标的减碳需求构建行业预期发展情景，得出在维持现状、常规预估、拆除限制、减量预估四类典型情景下，2022 年我国新建建筑结构隐含碳排放限值分别为442.6 kg CO₂e·m^-2、456.2 kg CO₂e·m^-2、485.9 kg CO₂e·m^-2、616.0 kg CO₂e·m^-2（对应结构设计服役年限50年）；给出2022—2060年建筑结构建造与维护碳排放限值的变化趋势，厘清了新建结构总量控制、既有结构延寿等减碳措施促使结构单体隐含碳排放限值宽松的成效。进一步从概率化调控、区域特征量化、可操作性、数据驱动优化等方面，提出了建筑结构隐含碳排放限值设定的相关建议。

《工程管理前沿（英文）》 2019年第6卷第4期页码 517-523 doi: 10.1007/s42524-019-0061-0

摘要： The core of China’s low-carbon development includes optimization of industrial structure, clean energy technologies, emission reduction technologies, and innovation of relevant systems and institutions. China National Petroleum Corporation (CNPC) has always been a proactive participant in developing low-carbon economy, shouldering the responsibilities of safeguarding oil and gas supply, conserving energy, and reducing emission. Therefore, CNPC fulfills those responsibilities as a substantial part of its overall strategy. Guided by low carbon and driven by innovation, petroleum corporations have taken constant innovation of low-carbon technologies, especially the development of green and low-carbon petroleum engineering technologies and equipment, as major measures for energy conservation and emission reduction. Large-scale development mode of unconventional resource anhydrous fracturing should be innovated. And supercritical CO should be used to replace water for fracturing operation, in order to achieve multiple objectives of CO burying, conserve water resource, improve single well production and ultimate recovery, realizing reduced emission and efficient utilization of CO resources. Artificial lifting energy-saving and efficiency-increasing technologies and injection-production technology in the same well should also be innovated. Energy consumption of high water-cut wells is reduced to support the new low-carbon operation mode of high water-cut oilfields and realize energy saving and efficiency improvement during oil production by developing the operation efficiency of the lifting system and reducing the ineffective lifting of formation water. These technologies have been widely recognized by local and international experts and have greatly enhanced CNPC’s international influence. This study expounds the key technologies and equipment with regard to the development of green and low-carbon petroleum engineering and provide relevant suggestions.

Life cycle carbon emission assessment of a multi-purpose university building: A case study of Sri Lanka

Ramya KUMANAYAKE, Hanbin LUO

《工程管理前沿（英文）》 2018年第5卷第3期页码 381-393 doi: 10.15302/J-FEM-2018055

摘要：

Buildings are known to significantly affect the global carbon emissions throughout their life cycle. To mitigate carbon emissions, investigation of the current performance of buildings with regard to energy consumption and carbon emissions is necessary. This paper presents a process-based life cycle assessment methodology for assessing carbon emissions of buildings, using a multi-storey reinforced concrete building in a Sri Lankan university as a case study. The entire cradle-to-grave building life cycle was assessed and the life span of the building was assumed as 50 years. The results provide evidence of the significance of operation and material production stages, which contributed to the total carbon emissions by 63.22% and 31.59% respectively. Between them, the main structural materials, concrete and reinforcement steel made up 61.91% of the total carbon emitted at the material production stage. The life cycle carbon emissions of the building were found to be 31.81 kg·m⁻² CO₂ per year, which is comparable with the values obtained in similar studies found in the literature. In minimizing the life cycle carbon emissions, the importance of identifying control measures for both building operation and material production at the early design stage were emphasized. Although the other life cycle stages only contributed to about 5.19% of the life cycle carbon emissions, they should also receive attention when formulating control strategies. Some of the recommended strategies are introducing energy efficiency measures in building design and operation, using renewable energy for building operation and manufacturing of materials, identifying designs that can save mass material quantities, using alternative materials that are locally available in Sri Lanka and implementing material reuse and recycling. This study is one of the first to undertake a life cycle carbon emissions assessment for a building in the Sri Lankan context, with the hope of facilitating environmentally-friendly buildings and promoting sustainable construction practices in the country.

张贤,李阳,马乔,刘玲娜

《中国工程科学》 2021年第23卷第6期页码 70-80 doi: 10.15302/J-SSCAE-2021.06.004

摘要：

碳捕集利用与封存（ CCUS）是实现碳中和目标不可或缺的重要技术选择。为了系统梳理技术发展现状、明确未来发展方向，本文对我国 CCUS 技术水平、示范进展、成本效益、潜力需求等进行了全面评估。我国 CCUS 技术发展迅速，与国际整体发展水平相当，目前处于工业化示范阶段，但部分关键技术落后于国际先进水平。在工业示范方面，我国具备了大规模捕集利用与封存的工程能力，但在项目规模、技术集成、海底封存、工业应用等方面与国际先进水平还存在差距。在减排潜力与需求方面，我国理论封存容量和行业减排需求极大，考虑源汇匹配之后不同地区陆上封存潜力差异较大。在成本效益方面，尽管当前 CCUS 技术成本较高，但未来可有效降低实现碳中和目标的整体减排成本。为此建议，加快构建 CCUS 技术体系，推进全链条集成示范，加快管网布局和基础设施建设，完善财税激励政策和法律法规体系。
