利用文献计量方法,基于Web of Science核心合集数据库,对2000—2023年全球电厂和煤化工厂耦合碳捕集、利用与封存(CCUS)的文献进行了系统分析。研究发现:(1)从发文量和发文趋势来看,美国一直位于电厂和煤化工厂耦合CCUS技术研究的领先地位,其中卡内基梅隆大学的H指数和篇均被引频次均为第一,在该领域国际影响力和话语权较高。中国在该领域发文量虽然较高,但H指数和篇均被引频次均较低,文献影响力仍有待提升。(2)从国际合作来看,美国、中国和英国是各国的主要合作对象,CCUS技术领先国家不断激励CCUS技术进步。(3)从研究热点来看,碳捕集和封存、生物质能碳捕集与封存技术(BECCS)和可再生能源替代是该领域的研究重点。近年来,BECCS、脱碳、生物质等关键词热度也迅速上升,CCUS技术结合生物能源被认为是实现CO2减排目标的关键技术路径。CCUS技术经济性的研究也成为学者的重点研究方向。 相似文献

面对日益严峻的全球气候变化形势和日趋紧迫的温室气体减排要求,全球主要经济体加强了在低碳与气候友好技术领域的国际合作,推出了主要经济体能源与气候论坛技术行动计划。技术行动计划集中关注了先进汽车、生物质能利用、碳捕集利用与封存、建筑部门提高能效、工业部门提高能效、高效低排放燃煤、海洋能利用、智能电网、太阳能利用和风能利用等10项低碳与气候友好技术。我国在技术行动计划中应以终端用能技术、核能技术为重点,在碳捕集利用与封存领域做好技术储备,在不同阶段采取财政补贴和排放交易的政策促进低碳与气候友好技术的发展。 相似文献

依据我国燃煤发电工业所面临的环境保护要求提高和温室气体减排压力等一些现实问题,把燃煤发电的工程子模型与能源CGE模型进行衔接而建立了混合CGE模型,通过对我国能源、经济和环境的复杂系统的仿真计算,对严格的节能减排政策下我国2030年以前的电力需求以及我国发展先进燃煤发电技术的节能量、大气污染物排放和温室气体排放进行了预测。结果表明,我国SO2排放问题在2030年以前将可以达到完全符合环保要求的标准,我国燃煤发电行业近期应该重点开发和推广高效脱硝技术。从可持续发展的观点来看,我国燃煤发电行业在中长期应该引入碳捕集与封存技术。 相似文献

Numerous energy scenarios consider concentrated solar power (CSP) technologies as an important option for mitigating global CO2 emissions. A global deployment of CSP technologies would generate significant economic opportunities for German CSP technology providers. The presented paper analyses potential economic benefits resulting from a global ramp up of CSP until 2050 based on scenarios of the International Energy Agency (IEA) and Greenpeace International. The analysis focuses on the economic opportunities of German technology providers which are among the leading international CSP market players. 相似文献

Business-to-business (B2B) electronic platforms have become important channels for transforming traditional modes of transaction. The success of these platforms relies heavily on the platform firms' customer orientation (CO) practices, which are designed to attract both sellers and buyers. This study draws on the cross network effect theory to explore whether and how a B2B e-commerce platform firm's (in)congruent CO strategic initiatives toward sellers or buyers affect the firm's performance. In addition, the moderating effects of seller-side and buyer-side demand uncertainty on the relationship between CO (in)congruence and platform firm performance are investigated. The analysis of data collected from 185 B2B electronic platform firms in China reveals that CO incongruence is more beneficial to firm performance than CO congruence. Furthermore, when seller-side demand uncertainty is high, an increase in seller-focused CO incongruence (i.e., higher seller orientation than buyer orientation) or buyer-focused CO incongruence (i.e., lower seller orientation than buyer orientation) improves or impedes a B2B e-commerce platform firm's performance, respectively. However, when buyer-side demand uncertainty is high, an increase in either type of CO incongruence does not improve firm performance. These findings contribute to the literature on and practices of B2B e-commerce and customer orientation. 相似文献

基于LMDI模型的CO2排放影响因素研究——以江苏省为例 总被引:1,自引:0,他引:1
本文采用Kaya及其扩展模型将CO2排放影响因素划分为产业能源强度、生活能源强度、能源结构、产业结构、人均产出、人居收入和人口总数7个方面。根据1995~2009年江苏省一、二、三产业和居民生活部门的12种能源消费数据,利用LMDI模型分解计算出7个因素的CO2排放量和贡献值。研究结果表明,1995~2009年江苏省CO2排放量总体呈上升趋势;人均产出、人居收入和人口总数对CO2排放起到正向驱动作用,产业能源强度、生活能源强度、能源结构、产业结构起到负向驱动作用,人均产出和产业能源强度分别是影响CO2排放的正向和负向主导因素。降低CO2排放量,需要通过提高产业能源强度、调整产业结构、能源结构和促进居民生活方式和消费模式的转变,要坚持计划生育的基本国策。 相似文献

Wind energy is one of the key technologies to become independent of fossil fuels. Implementation of wind energy on a local level, however, has sometimes proved to be challenging and dealing with local acceptance of onshore wind turbines has become troublesome for some projects. Communication and public involvement are seen as strategies to prevent or respond to local opposition. This paper analyses the views of a variety of experts in wind energy on this matter. It focuses on eliciting their experiences with public participation measures. Furthermore, the perceived effectiveness of the measures for the social acceptance of wind energy projects is analysed. To do so, this paper draws on an expert survey among 207 individuals across Europe linked to wind energy projects. The analysis shows that negative reactions to wind farms are reported more frequently than positive reactions. In nearly 40% of cases, projects experience negative consequences on project development due to a lack of social acceptance, ranging from delays to changes in project plans and even termination. The vast majority of wind project developers respond to this by carrying out public participation activity at least sometimes. However, a much lower share does this systematically and the level of activity is low in early project phases. With regard to the relationship between project activities and project success, there is some support for the assumption that early and systematic involvement of the public and stakeholders is likely to reduce negative reactions. 相似文献
