Sub-Surface Technologies (SST) Investigating and Optimizing Geological Storage and Resource Extraction

Whether for maximizing resource extraction or commodity storage, understanding geologic systems is a critical skill set. Maximizing geologic storage capacity is critical to enable the integration of renewables, contribute to grid stability, and make creation of a hydrogen economy possible. More research is needed before safe and responsible large-scale storage of hydrogen can be accomplished below ground. In addition, CO2 can also be permanently stored underground to minimize climate change impacts.
