Touted as the most promising interim solution to deal with the greenhouse gas responsible for global warming, CCS still remains unproven, costly and will not be commercially available for another 10-20 years. Meanwhile scientists are exploring alternatives to CCS by capitalizing on CO2 as a commodity instead of treating it as a waste. Some 27 billion tons of CO2 is already a hefty number but energy-related carbon dioxide emissions are projected to reach 43 billion metric tons p
