Squeezing Coal To Reduce Emissions

Posted by timothy on from the soon-you-will-have-to-register dept.

sbszine writes "Australian newspaper The Age has an interesting story on squeezing coal before burning it in order to reduce greenhouse gas emissions. The process, discovered by Victorian scientists, is expected to make brown coal (lignite) burn 30% cleaner. Good news, as Australia is the world's number one exporter of coal."

  1. It makes perfect sense... by ResidntGeek · · Score: 5, Informative

    Anthracite, the cleanest-burning coal, is also called hard coal because it's the densest variety and it contains the least moisture. Lignite, the type they squeezed, is the crappiest kind of coal. It is almost half water and is quite light. How many brilliant people did it take to think "maybe if we make lignite denser and take the water out, it'll burn more cleanly!"???
