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.
Lignite can be broken down chemically through coal gasification, the process of producing syngas from coal along with water, air and/or oxygen. This creates synthetic natural gas that delivers more power and is easier to operate in commercial scale electric generations.
