The building sector consumes a great deal of energy and generates organic waste, and thus has been a cause of considerable environmental concern. One distributed-energy technique, solid oxide fuel cell (SOFC)-based biogas-from-waste generation, has shown promise for waste treatment as well as energy saving in buildings. This study proposes a high-efficiency cooling, heating and electricity-generation system with an SOFC-absorption water-cooled tri-generation configuration. Operations data from a typical high-rise commercial building in Shanghai and an airport in Hong Kong were analyzed as case studies of the proposed system’s economic, environmental, and social feasibility in China. The results indicated that its economic performance was satisfactory, with a short payback period of less than one year if subsidized. Additionally, the system was found to achieve high efficiency: i.e., 85%, as compared to approximately 40% achieved by conventional combustion-powered systems. Finally, in terms of social feasibility, survey respondents not only expressed positive overall attitudes towards the application of the system but also raised concerns about its long-term operating costs. Given that foreseeable technological advancements promise greater flexibility and reduced space requirements, these results imply that the proposed integrated SOFC multi-generation system will be well-suited to future infrastructure and building projects in China.

建筑领域已经成为了最大的能源消耗者和有机废物生产者。因此,建筑行业对于环境的影响引起了越来越多人的关注。一种分布式能源技术,使用基于有机垃圾制造沼气的固体氧化物燃料电池(SOFC),已显示出在废物处理和建筑节能方面的希望。本研究提出了一种具有柔性吸收式水冷三联供结构的高效冷、热、电三联供系统。以上海某典型高层商业建筑和香港某机场的运营数据为例,分析了该系统在中国的经济、环境和社会可行性。结果表明,它的经济表现令人满意,如果得到补贴,其资本回收期甚至不到一年。此外,我们发现该系统的效率很高:这一比例为85%,而传统燃烧动力系统的这一比例约为40%。最后,在社会可行性方面,被调查者不仅对该制度的应用表达了积极的总体态度,还对其长期运行成本表示了担忧。鉴于可预见的技术进步将带来更大的灵活性和更少的空间需求,这些结果意味着拟议的综合SOFC多级联产系统将非常适合中国未来的基础设施和建筑项目。
