**Abstract**
China is rich in unconventional energy resources, particularly in the fields of combustible ice (also known as methane hydrate) and shale gas. These resources hold great potential to reshape the country’s energy landscape in the coming decades.
In terms of combustible ice, China's reserves are vast, with major deposits located in the South China Sea, the East China Sea, the Qinghai-Tibet Plateau, and the permafrost regions of Northeast China. According to preliminary estimates, the total resource volume is approximately 64.97 trillion cubic meters, with recoverable reserves estimated at around 3.38 trillion cubic meters. The northern slope of the South China Sea alone holds about 18.5 billion tons of oil equivalent in combustible ice—equivalent to six times the proven oil and gas reserves from deepwater exploration in that region. Globally, combustible ice reserves are estimated at around 10 trillion tons, which could meet human energy needs for over a thousand years if fully utilized.
Regarding shale gas, the Ministry of Land and Resources announced in March 2023 that China's potential geological shale gas resources amount to 134.42 trillion cubic meters, with recoverable reserves estimated at 25.08 trillion cubic meters (excluding the Qinghai-Tibet area). This is comparable to conventional natural gas reserves. Key areas for future development include the Sichuan Basin, eastern and western Hubei, the Xiaoxiang region, the Ordos Basin, and the Tarim Basin.
Under the "Twelfth Five-Year Plan," the goal was to reach 600 billion cubic meters of proven shale gas reserves and 200 billion cubic meters of recoverable reserves by 2015, with an annual output of 6.5 billion cubic meters. By 2020, the target was to increase production to between 60 billion and 100 billion cubic meters annually. If these targets are met, shale gas could significantly alter China's energy structure, becoming a key pillar of the nation's energy supply. With continued investment and technological advancements, China has the potential to become a global leader in the exploitation and utilization of these clean and abundant energy sources.
