该项目评估了新墨西哥州Rio Grande裂谷盆地的高热焓地热开发潜力。通过增强型地热系统（EGS）中开采热能并用于综合发电。以CO2作为工作流体对EGS进行了评估，并提出了其优缺点。整体煤气化联合循环发电系统（IGCC）是从煤碳中提取清洁能源的一种方式，其副产品是用作EGS工作流体的CO2。因为当地水资源匮乏，这对拟建的新墨西哥州地热开发具有很大优势。这种独特的组合预计将产生比传统EGS系统提供多出大约四倍的功率。
SUPERCRITICAL CARBON DIOXIDE CIRCULATED EGS COMBINED WITH IGCC IN NEW MEXICO
Executive Summary:The project evaluated the geothermal potential of the Rio Grande Rift, New Mexico for high enthalpy use. The high enthalpy production is utilized for the integrated generation of electricity by recovery from an enhanced/engineering geothermal system (EGS). The EGS was evaluated with CO2 as a working fluid and its benefits/disadvantages were proposed. Integrated Gasification and Combined Cycle (IGCC) is a way of obtaining clean energy from the coal and the by-product is CO2, which is used as the working fluid for EGS. This is especially beneficial for the proposed New Mexico site where water availability is a major concern. This unique combination is expected to generate about four times more power than that by a single conventional EGS system. |
