Natural gas hydrates are ice-like crystalline compounds formed by hydrocarbon gases, primarily methane, and water under specific temperature and pressure conditions. They typically occur in solid form within seabed sediments or in fractures and pores of rocks in permafrost regions on land. Also known as “combustible ice,” natural gas hydrates boast a high energy density and represent a clean, efficient energy resource and chemical feedstock.

  Natural gas hydrates are ice-like crystalline compounds formed by hydrocarbon gases, primarily methane, and water under specific temperature and pressure conditions. They typically occur in solid form within seabed sediments or in the fractures and pores of rocks in permafrost regions on land. Natural gas hydrates are also known as “combustible ice”; they possess a high energy density and constitute a clean, efficient energy resource and chemical feedstock.

  The conditions for the formation of natural gas hydrates include sufficiently low temperatures, relatively high pressures, and an adequate enrichment of the source materials—gas and water. In nature, natural gas hydrates are primarily found in permafrost zones surrounding the Arctic and in shallow marine shelf sediments. In China, favorable geological conditions for the occurrence of natural gas hydrates exist in the permafrost regions of the Qinghai–Tibet Plateau, as well as on the continental slopes of the East China Sea and the northern South China Sea.

  Natural gas hydrates hold broad application prospects in energy, chemical engineering, geology, and other fields. They can serve as a clean energy source for urban gas supply, combined heat and power generation, liquefied natural gas production, and the manufacture of chemical products. Moreover, natural gas hydrates are well suited for natural gas storage and long-distance transportation. In locations where on‑site storage is required, natural gas can be converted into hydrates and stored on the seabed or on land; the hydrates can then be decomposed to release the gas when needed. This approach offers distinct advantages, helping to address challenges associated with natural gas transport.

  In summary, natural gas hydrates are a novel energy resource with immense potential and broad application prospects, playing a crucial role in advancing the transformation of the energy mix and promoting sustainable development.
