Scientists at the Chinese Academy of Sciences and China University of Petroleum (Beijing) have demonstrated that CO2 may make a better hydraulic fracturing (fracking) fluid than water. Their research, published May 30 in the journal Joule, could help pave the way for a more eco-friendly form of fracking that would double as a mechanism for storing captured atmospheric CO2.
