Abstract

In order to reduce C02 emission to prevent global warming, the most promising way for electric generation in the Northeast Asia is to introduce highly efficient system technologies such as combined cycle, repowering, gas turbine integrated garbage incineration, gas turbine combined with coal fired steam power generation, gas turbine combined with nuclear power generation, and cogeneration including micro gas turbine and polymer fuel cell technologies. All of these energy system technologies should be based on natural gas as fuel. This paper presents a brief survey of these new technologies.
In accordance with the direction of introducing these highly efficient technologies of power generation, natural gas demand in the Northeast Asia should be drastically increased. To meet the big demand estimation, it is essential to have infrastructures as pipelines. As it is well known, in Europe, over 800,000km high pressure natural gas trunk pipelines have already been existed. In North America, there has been 440,000km in length existed. On the other hand, in Asia, there is nothing. This paper also proposes to construct the Northeast Asian Pipeline Network, by which natural gas is transported from candidate sources in East Siberia and in Central Asia to China, Mongolia, Korea, North Korea and Japan.
