Concluding Remarks

Developing a portfolio of resource aware technologies for greenhouse gas mitigation, utilization, and removal and the utilization of low-value residues to generate value-added materials is essential for realizing our societal goal of achieving a low carbon future. Towards this end, advancing the science of fluid-particle interactions and transformations in subsurface environments and engineered processes and harnessing this understanding to develop novel and scalable technologies is essential. In this context, we will discuss the role of emerging understanding of the organization and transport behavior of nanoconfined fluids as it relates to the storage and utilization of compressed fluids such as CO₂ and CH₄ in geologic environments. The development of novel fluids to enhance permeability in subsurface environments for heat mining and chemical pathways to limit silica scales in geologic reservoirs will be presented. To meet our energy needs in a sustainable manner, we will discuss multi-phase chemical pathways for producing hydrogen with inherent carbon removal and hybrid absorption-crystallization pathways for CO₂ capture and removal, with the potential for utilization. The role of naturally occurring minerals, biomass, low value residues including alkaline residues in advancing these pathways and the potential to produce essential materials such as carbonates for construction applications and battery materials will be presented.
