可逆固体氧化物燃料电池具有燃料电池和电解池两种运行模式，其电解模式可进行H_2O-CO2共电解，是一种新型碳转化技术手段。然而其在分布式能源系统中的应用研究尚不充分，主动减碳的潜力也有待发掘。提出了一种耦合太阳能的可逆固体氧化物燃料电池综合能源系统，建立了包含冷热电联供和主动碳减排的系统仿真模型，研究了不同季节系统运行特性和燃料利用率、气源以及价格变动下的技术经济性，并提出一种考虑能量效率、环境效益、经济性和可持续性的综合评价指标。以2 000 m2的办公建筑供能为例分析，在夏季太阳辐射充足时，最大日均主动碳减排量可达53 kg。此外，参数化研究表明燃料利用率、甲烷比例与能量效率和火用效率呈正相关，系统经济性能对电价最为敏感。本研究提出的主动碳减排能源系统区别于被动减排系统，实现了碳排放主动就地消纳，可与传统能源系统灵活耦合，以满足其低碳排放的需求。
Abstract：Reversible solid oxide fuel cells(RSOCs) possess both fuel cell and electrolysis cell operating modes, with their electrolysis mode capable of H_2O-CO2 co-electrolysis, serving as a novel carbon conversion technology. However, research on their application in distributed energy systems remains insufficient, and their potential for active carbon reduction has yet to be fully explored.This research proposes an integrated energy system coupling RSOCs with solar energy, establishes a system simulation model that includes combined cooling, heating, and power as well as active carbon emission reduction, and investigates the system's operational characteristics across different seasons, fuel utilization rates, gas sources, and price fluctuations. Additionally, a comprehensive evaluation index considering energy efficiency, environmental benefits, economic performance, and sustainability is proposed. Taking the energy supply of a 2 000 m2 office building as an example, the maximum daily carbon emission reduction can reach 53 kg in summer when solar radiation is abundant. Furthermore, parametric studies indicate that fuel utilization rates and methane proportions are positively correlated with energy efficiency and exergy efficiency, while the system's economic performance is most sensitive to electricity prices. The active carbon reduction energy system proposed in this study differs from passive reduction systems by achieving on-site active carbon emission absorption and can flexibly couple with traditional energy systems to meet the low-carbon emission requirements.
