A feasible alternative to the Hydrogen Economy and other proposals is the Methanol Economy. The emissions of fossil-fuel-burning power plants and varied chemical and industrial plants contain high concentrations of CO2 that can be readily captured and recycled to methanol. Methanol can be readily converted to ethylene and/or propylene (the methanol-to-olefin (MTO) process), which can then be further transformed to synthetic hydrocarbons and their products that are presently obtained from oil and gas. Petroleum oil and natural gas reserves could be extended somewhat by their better and more economical use, conservation measures, and the introduction of improved, more efficient technologies, particularly in the transportation area where oil-based fuels continue to be primarily used. Engines specifically designed to run on methanol being developed offer exceptional efficiencies and cleaner emissions when compared with other types of engines.
