摘要
由于世界油气资源的涨价和环境问题的严重,促使人们对一级能源的重新选择。与核能、水能和其他可再生能源相比,煤地下气化(UCG)是最好的选择。目前,澳大利亚、英国、南非都有快速的发展,煤地下气化技术已包括UCG-IGCC-CCS,UCG-AFC-CCS,UCG-GTL-CCS等的新方向,真正意义上地实现减排的效果。事实证明UCG的成本低廉,效率高、环境友好。尤其英国正在建由UCG供氢氧的300MW燃料电池,并通过燃料电池(AFC)发电的电站,可以达到零排放。所以,煤地下气化是解决确保国家的能源安全、CO2减排和环境污染、以及采煤矿工人身安全的一把金钥匙。因此,UCG应当是中国一级能源发展的主要方向。
Due to the rise of price of world oil and gas resourcesand serious environment problems, people again need choice in pri- mary energy. Compared to nuclear energy, water and other renew- able energy, people have to consider to the use of clean coal. Un- derground coal gasification is a best choice. Now Australia,The U- nited Kingdom, South African and so on have made quikly impor- tant developments. They put the technologies for UCG-IGCC- CCS, UCG-AFC-CCS, UCG-GTL-CCS together and realise the re- ally emission reduction. The facts show that underground coal gasi- fication （UCG） have the lower cost, higher effeciency and friendly environment. Especially the fuel cell power station of the scale 500 MW is being built and hydrogen as the fuel provided by UCG and finally achieved the zero emission. UCG is a golden key or a solu- tion to ensure the security of country＇s energy, the reduction of CO2 emission and enviorment pollution, and the safety of mine workers body. So UCG should be the main direction of the primary energy for our country in the future.
