Scrubbing colloidal coal

To environmentalists the concept of "clean coal" is considered an oxymoron, however, unperturbed by those with doubts, chemists at Nano Dispersions Technology in Panama, have developed a new form for an old fuel based on a colloidal coal-water suspension that avoids the problems associated with current coal-slurry alternatives to oil. When burned in an ordinary boiler fitted with a sulphur scrubber, colloidal coal can decrease emissions of that element. The company is now investigating whether carbon dioxide emissions can be trapped during burning without having to use a separate carbon capture facility.
