基于生命周期分析（LCA）方法的地热发电环境影响比较研究

本研究基于全生命周期理论，通过划定统一评价边界，分环节核算地热发电及其他发电方式的环境及经济效益，填补不同发电方式环境影响横向对比研究的空白。不仅可以对地热发电的环境效益进行全面评价并以此提出未来优化方向，更能为城市群低碳转型路径中电源结构低碳化发展方向提供决策依据。地热发电作为可再生能源发电方式之一，在应对气候变化、加速能源转型和保障能源安全3方面挑战下，具有广阔的市场前景和竞争力。

Comparative Research on the Environmental Impact of Geothermal Power Generation Based on Life Cycle Assessment

This study calculated the environmental and economic benefits of geothermal power generation and other power generation methods by defining a unified evaluation boundary based on the whole life cycle theory. This filled the blank of horizontal comparative study on the environmental impact of different power generation modes. It not only comprehensively evaluated the environmental benefits of geothermal power generation and put forward the future optimization direction, but also provided decision-making basis for the low-carbon development direction of power structure in the low-carbon transformation path of urban agglomeration. As one of the renewable energy power generation methods, geothermal power generation has broad market prospects and competitiveness under the challenges of coping with climate change, accelerating energy transformation and ensuring energy security.
