Abstract

Environmental impact, energy efficiency and cost optimization are basic aspects when selecting heat transfer fluids (HTF) for CSP plants. The present study evaluates the environmental impact of four CSP HTF types (Thermal Oil, Liquid Metal, Molten Salt and Silicone-based), by analyzing different traditional and innovative fluids, such as Therminol VP-1®, Liquid Sodium, Lead-bismuth eutectic, Solar Salt, Hitec®, Hitec XL® and Helisol® 5A. All fluids underwent a life cycle analysis with the ReCiPe 2016 method, using the Ecoinvent 3.8 database, the SimaPro 9.3 software and the “cradle-to-grave” perspective to detail their impacts on Human Health, Ecosystem Quality, and Resource Availability. For the hypothesized scenario, results show how Hitec XL® presented the lowest cost and environmental impact values (1.19 US$/kg and 104.99 mPt/kg), being up to 3.6 times more sustainable. Therminol VP-1® obtained the highest environmental impact score, being up to 88.5% more unfavourable than Hitec XL® and 73.4% than the rest of fluids. The area with the highest impact was Human health (92.54%), with a significant influence of the Fine Particulate Matter formation category (40%). The knowledge developed will provide a detailed insight into the environmental impact in CSP plants, complementing current performance data and contributing to the energy sector’s decarbonization.

抛物槽式光热电站传热流体的生命周期及环境影响评价

环境影响、能源效率和成本优化是为CSP电厂选择传热流体（HTF）的基本方面。本研究通过分析不同的传统和创新流体，如Therminol VP-1®、液态钠、铅铋共晶、Solar Salt、Hitec®、Hitec XL®和Helisol®5A，评估了四种CSP HTF类型（热油、液态金属、熔盐和硅基）对环境的影响。所有流体均采用ReCiPe 2016方法进行生命周期分析，使用Ecoinvent 3.8数据库、SimaPro 9.3软件和“从摇篮到坟墓”的视角，详细分析其对人类健康、生态系统质量和资源可用性的影响。在假设的情况下，结果表明，Hitec XL具有最低的成本和环境影响值（1.19美元/公斤和104.99万吨/公斤），可持续性提高3.6倍。Therminol VP-1获得了最高的环境影响评分，比Hitec XL高88.5%，比其他液体高73.4%。影响最大的领域是人体健康（92.54%），其中细颗粒物形成类别影响显著（40%）。所开发的知识将为CSP电厂的环境影响提供详细的见解，补充当前的性能数据，并为能源部门的脱碳做出贡献。
