Greener Generation(更环保的能源生产)
Despite the surfeit(过量) of soot(烟灰), the average Chinese citizen accounts for a mere fraction(一小部分) of the greenhouse emissions of the average American. Sheer population overcomes the small per capita number, however, and the country is not bound by any international treaty to reduce its pollution.
Nevertheless, the government has at least started to tackle the problem by launching a pilot project to capture and store the carbon dioxide (CO2) produced from burning coal at a demonstration power plant dubbed GreenGen.
The project, in the Yellow Sea port city of Tianjin northeast of here, will proceed in three phases. First, a consortium of power and coal companies will construct a so-called integrated gasification (气化)combined cycle power plant. In this design, coal is converted into a gas, and pollutants are removed before the gas is burned. Such technology could cut acid rain–causing sulfur dioxide emissions by more than 90 percent and smog-forming nitrous oxides by 75 percent—as well as capturing more than 80 percent of the CO2 emitted by 2015 and storing it in nearby depleted (大大减少的)oil fields.
The $1-billion GreenGen plant became the world’s leading clean coal project in January after the U.S. government pulled the plug on FutureGen, a similar demonstration plant in Mattoon, Ill., that lost steam as construction costs skyrocketed(突升). The cancellation came despite the fact that the United Nations Intergovernmental Panel on Climate Change and leaders of the world’s eight richest nations (the G8), including President George W. Bush, had called the development of clean coal technology essential to preventing the consequences of climate change.
