Of the known greenhouse gases, political attention to date has primarily focused on carbon dioxide (CO2), whereby it is assumed that underground storages of crude oil and natural gas through Carbon Capture and Storage (CCS) technology could contribute significantly to global climate protection. Underground Storage of CO2 and Energy covers many aspects of CO2 sequestration and its usage, as well as of underground storage of fossil and renewable energy sources, and is divided into 8 parts: * Environmental and Energy Policy & Law for Underground Storage * Geological Storage and Monitoring * Enhanced Gas and Oil Recovery Using CO2 (CO2 -EGR/EOR) * Rock Mechanical Behavior in Consideration of Dilatancy and Damage * Underground Storage of Natural Gas and Oil * Underground Storage of Wind Energy * State-of-the-Art & New Developments in Gas Supply in Germany and China * EOR & New Drilling Technology Underground Storage of CO2 and Energy will be invaluable to academics, professionals and engineers, and to industries and governmental bodies active in the field of underground storage of fossil and renewable energy sources.

Widespread influence of fluids on rock strength and deformation characteristics from grain-scale to lithospheric-scale has led to a necessity of understanding the hydro-mechanical coupling in strength, deformation, and fracturing behaviors of rock materials. This book provides experimental and numerical approaches for investigating the effects of hydro-mechanical coupling on shear-induced rock fractures using Punch Through Shear experiments and 2D hydro-mechanical coupled bonded particle model simulations. Especially,this book presents how the conventional 2D bonded particle modeling was modified to handle the hydro-mechanical coupling processes in rock and also deals with a new method for microparameter determination for bonded particle model generation. Therefore, this book should be helpful to anyone who may be considering using the bonded particle model in simulations of rock fracturing in geotechncal problems.
