高聚光光伏热（HCPV/T）系统产生电能和热能，它们在具有高直接正常辐照度（DNI）的地区是有效的。本文估计了HCPV/T 2000x系统在电气和热功能方面的生命周期环境影响。采用基于过程的归因方法，遵循ISO 14044/40的指导方针和框架进行生命周期评估（LCA）。研究了中点和终点影响类别。研究发现，主要的热点是热能系统的生产，分别贡献了50%和55%，其次是跟踪系统的生产，分别贡献了29%和32%，运维分别贡献了13%和7%。发现生命周期环境影响类别指标的主要贡献者是热能和跟踪系统的原材料获取/生产和制造。结果表明，与基于燃料的热电联产（CHP）和非可再生能源（non-RES）系统相比，HCPV/T 2000x系统的生命周期环境影响较低。
High Concentrator Photovoltaic Thermal (HCPV/T) systems produce both electrical and thermal energy and they are efficient in areas with high Direct Normal Irradiance (DNI). This paper estimates the lifecycle environmental impact of the HCPV/T 2000x system for both electrical and thermal functionalities. Process-based attributional method following the guidelines and framework of ISO 14044/40 was used to conduct the Life Cycle Assessment (LCA). The midpoint and endpoint impact categories were studied. It was found that the main hotspots are the production of the thermal energy system contributing with 50% and 55%, respectively, followed by the production of the tracking system with 29% and 32% and the operation and maintenance with 13% and 7%. The main contributor to the lifecycle environmental impact category indicators was found to be the raw materials acquisition/production and manufacturing of the thermal energy and tracking systems. The results indicate that the lifecycle environmental impact of the HCPV/T 2000x system is lower compared to fuel-based Combined Heat and Power (CHP) and non-Renewable Energy Sources (non-RES) systems.
