What is lignite coal used for?
Sometimes called "brown coal," lignite is the lowest quality and most crumbly coal. This softer and geologically "younger" coal sits relatively close to the earth's surface.

This creates synthetic natural gas that delivers more power and is easier to operate in commercial scale electric generations.
