Geologic energy storage
Introduction As the United States transitions away from fossil fuels, its economy will rely on more renewable energy. Because current renewable energy sources sometimes produce variable power supplies, it is important to store energy for use when power supply drops below power demand. Battery storage is one method to store power. However, geologic (underground) energy storage may be able to retain
Assessing global geologic carbon dioxide storage resources
Focus areas for data acquisition for potential domestic resources of 13 critical minerals in the conterminous United States and Puerto Rico — Antimony, barite, beryllium, chromium, fluorspar, hafnium, helium, magnesium, manganese, potash, uranium, vanadiu
National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources — Summary
National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources — Results
National assessment of helium resources within known natural gas reservoirs
Compositional analysis of formation water geochemistry and microbiology of commercial and carbon dioxide-rich wells in the southwestern United States
Methodology for estimating the prospective CO2 storage resource of residual oil zones at the national and regional scale
