Potential applications based on the formation and dissociation of gas hydrates

Owing to the substantial deposits and widespread applications of gas hydrates, research in gas hydrates has been increasing in recent decades. The inherent excellent physiochemical properties of gas hydrates determine the prominent roles that they play in a wide range of areas including energy and environment. Particularly, gas hydrates represent an attractive way for gas storage, gas separation, wastewater treatment, and other fields. The review summarizes the potential applications based on hydrate formation and dissociation. Challenges, limitation, and future visions of every application are discussed. The whole purpose of this paper is to give readers with a comprehensive understand of hydrate-based applications, stimulate further innovation application research using hydrate formation and dissociation, and give some useful guidance for their industrialization. •The excellent physiochemical properties of gas hydrates determine their great potential in industrial applications.•The potential applications including gas storage, gas separation, wastewater treatment, and other fields are reviewed.•Challenges, limitation, and future perspectives of each field are discussed.
