A life cycle assessment (LCA) focused on greenhouse gas (GHG) emissions from the production of microalgal biodiesel was carried out based on a detailed engineering and economic analysis. This LCA applies the methodology of the California Low Carbon Fuel Standard (CA LCFS) and uses life cycle inventory (LCI) data for process inputs, based on the California-Modified Greenhouse Gases, Regulated Emissions, and Energy use in Transportation (CA GREET) model. Based on detailed mass and energy balances, calculated GHG emissions from this algal biodiesel system are 70% lower than those of conventional diesel fuel, meeting the minimum 50% GHG reduction requirements under the EPA RFS2 and 60% for the European Union Renewable Energy Directive. This LCA study provides a guide to the research and development objectives that must be achieved to meet both economic and environmental goals for microalgae biodiesel production.
基于详细的工程和经济分析，进行了一项侧重于微藻生物柴油生产过程中温室气体（GHG）排放的生命周期评估（LCA）。本 LCA 采用了加利福尼亚低碳燃料标准（CA LCFS）的方法，并使用基于加利福尼亚改良温室气体、法规排放和运输中的能源使用（CA GREET）模型的工艺投入生命周期清单（LCI）数据。基于详细的质量和能量平衡，该藻类生物柴油系统的 GHG 排放量比传统柴油低 70%，满足 EPA RFS2 下至少 50%的 GHG 减排要求和欧盟可再生能源指令的 60%。本 LCA 研究为满足微藻生物柴油生产的经济和环境目标提供了研究和开发目标的指南。
