Every fuel takes more energy to produce than you can get out of it. This will be true whether the fuel is ethanol or anti-matter. It's the second law of thermodynamics.

What makes a fuel non-polluting is the waste products. A fuel that, when used, gives off water is non-polluting compared to a fuel that gives off carbon monoxide. In this case, if the polymeric nitrogen could be converted to the more stable triple-bonded molecule, you would get common molecular nitrogen and a lot of energy. Thus, this has the potential to be a non-polluting fuel source.
