The article talks about making coal cleaner for the environment by using advanced technologies. They focus on improving coal-fired power plants by reducing the amount of CO2 they release. Two main methods are discussed: one called pulverized coal systems and another one called gasification. There's an idea to burn coal underground, known as underground coal gasification, to make electricity with less harm to the environment. The US government plans to create a special plant, called FutureGen, to show this new technology. This plant aims to produce electricity with very little pollution, and it could be a big step toward cleaner energy from coal. The article concludes that with these technologies, we can start making coal plants better for the planet right now.
