这项工作调查了燃料电池（FC）作为热电联产（CHP）原动机在商业建筑中的可行性，并特别关注超市。从一家FC制造公司获得了最新的技术数据，并应用于评估其在现有食品零售建筑中的可行性。一个详细的优化模型，以加强分布式能源系统管理在以前的工作中描述的扩展，以优化FC-CHP系统的技术经济性能。优化采用反映当前市场趋势的综合技术经济数据集。产出突出了影响FC-CHP项目经济效益的关键因素。此外，与竞争的内燃机（ICE）热电联产系统进行了比较分析，以了解每个系统的相对技术经济特征。研究结果表明，尽管ice仍然是一个更有吸引力的选择，但fc在财务上正变得具有竞争力。对于超市来说，安装FC系统的投资回收期为4.7-5.9年，而考虑到政策因素，安装ice系统的投资回收期为4.0-5.6年。如果取消激励措施，FC-CHP系统的回报期为6-10年，而基于ice的系统的回报期为5-8.5年。在不同的市场和政策情景下进行了敏感性分析，为燃料电池在变得更具竞争力之前面临的性能差距提供了见解。(C) 2020 Elsevier Ltd.版权所有。
This work investigates the viability of fuel cells (FC) as combined heat and power (CHP) prime movers in commercial buildings with a specific focus on supermarkets. Up-to-date technical data from a FC manufacturing company was obtained and applied to evaluate their viability in an existing food-retail building. A detailed optimisation model for enhancing distributed energy system management described in previous work is expanded upon to optimise the techno-economic performance of FC-CHP systems. The optimisations employ comprehensive techno-economic datasets that reflect current market trends. Outputs highlight the key factors influencing the economics of FC-CHP projects. Furthermore, a comparative analysis against a competing internal combustion engine (ICE) CHP system is performed to understand the relative techno-economic characterisitcs of each system. Results indicate that FCs are becoming financially competitive although ICEs are still a more attractive option. For supermarkets, the payback period for installing a FC system is 4.7-5.9 years vs. 4.0-5.6 years for ICEs when policies are considered. If incentives are removed, FC-CHP systems have paybacks in the range 6-10 years vs. 5-8.5 years for ICE-based systems. A sensitivity analysis under different market and policy scenarios is performed, offering insights into the performance gap fuel cells face before becoming more competitive. (C) 2020 Elsevier Ltd.
