Special Issue Information
Dear Colleagues,
Natural gas is considered a clean energy source that enables human society to transition from a fossil fuel-dominated phase to a sustainable and renewable energy-dominated phase. Fortunately, natural gas hydrates could become an important source of natural gas in the near future. It was estimated that the global reserves of natural gas hydrates are as high as 3 × 1015 m3, which is about double the reserves of conventional fossil fuels (such as oil, gas, and coal). In the stable structure of gas hydrate, natural gas is firmly fixed in the center of the cage structure that is composed of water molecules. Once its stable state is disturbed, natural gas escapes from the cage structure, allowing it to be extracted and utilized. At present, the commonly used development strategies mainly include depressurization, thermal stimulation, inhibitor injection, and CO2 replacement. Unfortunately, there will be many environmental challenges during its long-term development process using these strategies. For example, inhibitors injected into hydrate-bearing sediments can contaminate pore fluids and cause damage to the reservoir. Therefore, exploring strategies for producing energy from natural gas hydrates in an environmentally friendly and efficient manner has become particularly important.
This Special Issue on “Environmentally Friendly Production of Energy from Natural Gas Hydrates” seeks high-quality research focusing on environmentally friendly production strategies for natural gas hydrates. Topics include, but are not limited to, the following:
(1) Impact of hydrate development on the environment and ecology, including analysis of engineering geological issues, methane leakage, reservoir damage, and contamination by chemical reagents.
(2) Development of environmentally friendly chemicals for hydrate development, such as drilling fluid additives, fracturing fluid additives, and various inhibitors.
(3) Application of industrial waste (such as power plant flue gas and waste heat) or low-quality energy (such as geothermal energy) in the efficient development of hydrates.
(4) Economic and technical evaluation of various environmentally friendly production strategies for natural gas hydrates.
