Gas hydrate is abundant in nature, its vast global resource volume represents one of the largest known unconventional energy sources. Gas hydrates have high energy density, their reservoirs can provide significant volumes of natural gas compared to natural gas reservoirs. Gas hydrate is a much cleaner alternative to crude oil and coal and could be a new clean energy source. It produces less carbon dioxide per unit of energy and fewer pollutants such as sulfur dioxide and particulates. It is expected that based on the advances of production technologies, offshore gas hydrate could be commercially viable for production in 10 to 15 years. This will play a critical role in the world energy transition and net-zero journey. US is the world's leader on gas hydrate production research and technology development since 2000, followed by Japan, China, and India. Having papers from three of these countries, this session reflects the most advanced technologies of offshore gas hydrate production.
