Here's a novel twist on curbing greenhouse gases. Some scientists and companies are examining ways of using captured carbon dioxide to extract fossil fuels.
It works like this. Carbon dioxide from smokestacks would be captured and compressed, and then shuttled into pipelines to oil fields. The gas would then be forced into oil wells to extract more fossil fuels.
The scenario solves two major problems in the energy field. First, what do you do with all of the carbon dioxide? The leading idea is to store it underground in depleted mines or saline aquifers. By being forced into oil … Read more
