Abstract: To meet the increasing demand of clean energy in China, more than RMB Yuan 400 billion investment has been planned to contract several coal to synthesized natural gas (Coal to SNG) project in the regions of China where there are abundant coal reserve with fewer people. Meanwhile, it has been demonstrated that the successful development of shale gas in USA leads to the excessive supply of natural gas in USA and causes the ratio of oil to gas price continuously increasing. In the 12th “5 year plan”, shale gas development has been one of the main focuses, which is expected to supply more and more natural gas from shale gas reserves. This in return would give rise to the economical risks to the coal to synthetic natural gas projects, which requires intensive invest and long payback period. To mitigate the long term economic risks of coal to SNG project, it is recommended to consider the conversion of coal to SNG project into coal to oil project in the future when the gas demand is less than requirements. Because from the technology view, coal to SNG and coal to oil processes have the similar steps and common features.
