The GEOENVI project developed a simplified Life Cycle Assessment (LCA) method to assess the environmental impacts of planned or operational deep geothermal plants. This methodology helps prospective developers of deep geothermal energy projects to evaluate the environmental performance of their planned project, in particular against fossil alternatives. The use of the GEOENVI LCA methodology allows to quantify quickly what benefits will result from the development of a geothermal project, and facilitates public acceptance and engagement.
Life Cycle Assessment methodology for deep geothermal energy projects
Several LCA experts and geothermal energy stakeholders came together to design the LCA methodology in the framework of the GEOENVI project. The aim was to identify how to best quantify the expected environmental impacts and benefits of a planned geothermal project. The experts used several case studies to develop this methodology, providing a typology of geothermal power and heat plants. From the full assessment of several key case studies, the experts established a simplified methodology. Developers can use this methodology to obtain a reliable estimate of the environmental impacts of their planned project, which can feed into required documents, such as Environmental Impact Assessments.
