The public and government have grown increasingly concerned that emissions of carbon dioxide from the burning of fossil fuels will lead to changes in climate, including global warming. Because it is unrealistic to expect this nation or the world to quit burning fossil fuels anytime soon, people have begun working on programs to capture carbon dioxide from power plants, inject it underground, and store it there. And government has begun enacting the rules that will govern this process, which sometimes is called carbon sequestration.
The Environmental Protection Agency, for example, has drafted rules relating to underground injection of carbon dioxide. And, in 2009, Louisiana enacted the Louisiana Geologic Sequestration of Carbon Dioxide Act to provide for state rules and regulations relating to carbon sequestration. As for technological research and development, much of the work done so far has related to carbon capture, but Matthew Wald has written an interesting article that appeared in the New York Times about a promising pilot-scale program that actually has begun the underground injection of carbon dioxide for purposes of sequestration.
This subject is of significant interest to the oil and gas industry, both because oil and gas are fossil fuels whose use sometimes is attacked by those who fear climate change, and also because depleted oil and gas reservoirs may be an ideal locations for carbon sequestration. Wald's article is well worth reading if you are interested in the subject.
