Has Fracking Gone ‘Green’?
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.
