A review on the methane emission detection during offshore natural gas hydrate production

Frontiers in Energy Research, 2023
Due to the high energy density, large potential reserves and only release CO2 and water after combustion, natural gas hydrate (NGH) is considered as the most likely new clean energy source to replace traditional fossil energy (crude oil, natural gas, etc.
