燃料电池热电联产技术应用于公共建筑的可行性
Feasibility of fuel cell-based CHP systems applied to public buildings
摘要:
模拟基于燃料电池、微型燃气轮机、内燃机的热电联产机组以及传统供能方式为不同气候区的5类公共建筑供能的不同情景,分别采用运行费用节省率、碳减排比率、简单回报期3个指标来分析各种供能情景下的技术、经济与环境可行性。给出了各类供能技术为各地区酒店类建筑供能的全寿命周期的成本,并对比了平准化发电成本。对基于燃料电池的热电联产系统投资回报期进行了投资成本和燃料价格等参数的敏感度分析。结果表明,当初投资下降到现有价格的50%时,该技术具有较强的投资吸引力。
Abstract:
Simulates various scenarios of fuel cell-based, micro-gas turbine-based, internal combustion engine-based combined heat and power(CHP) system and conventional system for energy supply to five types of public buildings located in five different climate zones in China. Adopts three indexes of operating cost reduction rate, carbon emission reduction rate and payback period to evaluate the economy and environment of each scenario. Compares the project life cycle cost and levelized cost of electricity for each system in the hotel buildings located in each climate zone. Conducts a sensitivity analysis on the payback period of fuel cell-based CHP systems by two parameters of the capital cost and fuel cost. The results show that the technology has strong investment attractiveness when the initial cost is reduced by 50%.
