Division/Committee: [GEOC: Division of Geochemistry]

Subsurface environments play a crucial role in energy production and waste storage. Utilizing subsurface space for clean energy production and carbon sequestration has become a key strategy for achieving a carbon-free economy. Despite significant advancements in understanding chemical and chemically induced physical processes (chemomechanics) through in situ time-resolved techniques and computational simulations, many critical questions and challenges remain. This session highlights recent advances in experimental and computational methods that enhance our understanding of reactions in subsurface environments. The topics to be covered in this session include, but are not limited to: Origin of geologic H2; Geothermal energy production; Nucleation, growth and multiphase reaction; Water/gas/solid interfaces; Underground storage of H2 and CO2; Underground gravity energy storage (air/CAES, compressed fluids); Radioactive waste disposal; Permeability manipulation; Fracture initiation/seismic effects; Caprock efficiency and improvement.
