With mounting demands for a CO2 tax to "save the planet" some alternatives to a tax are starting to surface. Sequestering CO2 in old oil fields to enhance oil production is well known. But what about using CO2 in producing liquid fuels? Really?!
Los Alamos lab has Developed a Process for CO2 Capture and Stripping from Air for Synthetic Fuels Production.
Researchers at Los Alamos National Laboratory have developed a process—called Green Freedom—for large-scale production of carbon-neutral, sulphur-free fuels and organic chemicals from air and water. The primary targets for the Green Freedom fuels are vehicles and aircraft. Source
CO2 to fuels would be "carbon neutral" because it would take CO2 from the air to produce fuel and when the fuel is burned CO2 is produced . But since this is an endless cycle no new net CO2 is added to the environment.
All of this, of course, is in addition to carbon neutral bio-fuels produced from emerging sources like Jatropha and algae.
