This CAREER research program addresses CO2-based energy production and storage to open potential paths for decarbonizing the energy sector. The project will identify conditions and characteristics that favor sustainable CO2 storage in subsurface geologic reservoirs. The principal applications targeted are using CO2 for production of geothermal energy and large-scale storage of intermittent power generated from renewable energy resources. Interactions between CO2, water, and rock will be examined to allow better prediction of the fate of injected CO2 in geologic reservoirs within the context of these emerging energy technologies. The research program will be integrated with the educational mission of raising student literacy of subsurface processes related to energy production, carbon mitigation, and sustainable groundwater management. UM undergraduate students will be directly engaged in research efforts by performing scenario analyses to define conditions under which CO2-based geothermal energy production can provide grid-scale energy with net negative life cycle CO2 emissions. Additionally, the educational program will build upon the PI's experience interfacing with middle school students on the topic of the energy-water nexus and leverage the UM Wolverine Pathways program to develop a series of educational modules for students in the greater metro-Detroit area. The Wolverine Pathways program follows a cohort of students from 7th through 12th grade, allowing the PI to develop and refine teaching modules through rigorous evaluation of student learning objectives over the span of the five-year project period. Once fully developed, these modules will be made freely available to educators through an online resource catalog coupled with companion video teaching tutorials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个职业研究计划解决了基于二氧化碳的能源生产和储存，为能源部门脱碳开辟了潜在的途径。该项目将确定有利于地下地质储层可持续CO2储存的条件和特征。目标的主要应用是利用二氧化碳生产地热能和大规模储存可再生能源产生的间歇性电力。将研究CO2、水和岩石之间的相互作用，以便在这些新兴能源技术的背景下更好地预测地质储层中注入CO2的命运。 该研究计划将与提高学生对与能源生产，碳减排和可持续地下水管理相关的地下过程的认识的教育使命相结合。UM本科生将通过执行情景分析直接参与研究工作，以确定基于CO2的地热能生产可以提供净负生命周期CO2排放的电网规模能源的条件。此外，教育计划将建立在PI与中学生就能源-水关系问题进行交流的经验基础上，并利用UM金刚狼途径计划为底特律大都市地区的学生开发一系列教育模块。该金刚狼路径程序如下一组学生从7日至12年级，允许PI开发和完善教学模块，通过学生的学习目标在五年的项目期间跨度严格的评估。一旦完全开发，这些模块将通过在线资源目录以及配套的视频教学教程免费提供给教育工作者。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
