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.

该职业研究计划涉及基于二氧化碳的能源生产和存储，以打开脱碳能源领域的潜在途径。该项目将确定有利于地下地质储层中可持续二氧化碳存储的条件和特征。针对性的主要应用是使用二氧化碳来生产地热能和可再生能源产生的间歇性功率的大规模存储。将检查二氧化碳，水和岩石之间的相互作用，以更好地预测这些新兴能量技术的地质储层中注射二氧化碳的命运。 该研究计划将与提高与能源生产，减少碳和可持续地下水管理相关的地下过程的学生素养的教育使命集成。 UM本科生将通过进行场景分析来定义条件，从而直接从事研究工作，在该方案下，基于二氧化碳的地热能生产可以提供网格尺度的能量，并具有净负面生命周期二氧化碳排放量。此外，教育计划将建立在PI与中学生有关能量水联系主题的经验基础上，并利用UM Wolverine Pathways计划为大都会区域的学生开发一系列教育模块。金刚狼途径计划遵循从7至12年级的学生队列，使PI通过对五年项目期间的学生学习目标进行严格的评估来开发和完善教学模块。一旦充分开发，这些模块将通过在线资源目录以及Companion Video教学教程的在线资源目录免费提供给教育工作。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的审查标准通过评估来通过评估来获得支持的。
