In recent years, interest for clathrate hydrates has increased, motivated both by their fascinating physiochemical and thermophysical properties and their industrial and practical promises in various areas of application.

Following the 2017 publication of Volume 1, which focused on fundamental aspects, modeling and characterization methods, this volume gathers a series of contributions addressing the natural occurrence of clathrate hydrates in sediments on Earth, with implications for the methane cycle, geohazards and energy resources, and then a few promising industrial applications.

This volume is intended for scientists, PhD students and engineers who wish to start working on clathrate hydrates and/or want to acquire general knowledge in this area. It presents, in a simple way, the approach commonly used to investigate marine gas hydrates and details numerical models to describe the geochemical and geomechanical dynamics of such systems. The volume ends with state of the art reviews on the promises and challenges of using clathrate hydrates in technologically important areas: cold storage and distribution, and geological storage in marine sediments of carbon dioxide and its capture from gaseous, methane-rich streams.
