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. "
step 1: capture emissions
step 2: store emissions
step 3: ? (put back where we found it, if we cant see it then its OKAY!)
step 4: TEh PROFIT!!1!
Good people go to bed earlier.
We MUST start accumulating vast reserves of liquid carbon dioxide NOW, so that in 50 years, when we're in the deadly throes of Global Cooling, we can release it to the atmosphere to warm the planet and save us all!
yeah, why the heck don't they convert the CO2 into something usable, like C and O2?
Maybe build another generating plant next door that supplies the energy required to break the molocules...
"What will exactly happen when the liquid CO2 will eventually warm up undergorund and then some future seismic event will open a crack ?
I hope this storage is somwhere in Sahara desert, not in the heart of densly populated Europe."
