Germany Fired Up Over Clean Coal
MIT's Technology Review is reporting on the world's first coal-driven power plant designed to capture and store C02 emissions. "Vattenfall's small 30-megawatt plant burns the lignite in air from which nitrogen has been removed. Combustion in the resulting oxygen-rich atmosphere produces a waste stream of carbon dioxide and water vapor, three-quarters of which is recycled back into the boiler. By repeating this process, known as oxyfuel, it is possible to greatly concentrate the carbon dioxide. After particles and sulfur have been removed, and water vapor has been condensed out, the waste gas can be 98 percent carbon dioxide, according to Vattenfall. The separated carbon dioxide will be cooled down to -28 C and liquefied. Starting next year, the plan is to transport it by truck 150 miles northwest, to be injected 3,000 meters underground into a depleted inland gas field in Altmark. Ideally, in the future, the gas will be carried by pipeline to underground storage, says Vattenfall. "
If it's pure CO2 they are capturing and storing, why don't they just release it into the Amazon rain forest?
Storing CO2 is not a viable solution, but giving it to the trees, who live on it and will convert it into 02, is!
Great idea. The problem is this:
How do you keep the CO2 in the rain forest long enough to be converted? How do you keep it from blowing away? How do you transport it from Germany, in Europe, to the Amazon, in S. America?
On second thought, it's not such a great idea. Sorry.
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.
they really want us using fewer resources because we are BAD for doing so. It is a behavior change they are looking for, not really a change in the percentage of CO2 put into the atmosphere.
Agreed. And this is why I don't like most environmentalists. They are too into ideology. Most are smug and arrogant too. In my opinion, a large number of these people just like to think they are better than everyone else.
