Stone Horn Ridge LLC is an Alaska energy company formed to expand energy options through underground coal gasification (UCG). UCG is a proven technology that converts deeply buried, unmineable coal into energy-rich syngas, a domestic, secure and environmentally sound source of clean energy. UCG-produced syngas is a bridge fuel that can be used to generate electricity, upgraded into synthetic natural gas or used as feedstock for producing clean-burning liquid fuels such as gasoline, diesel and jet fuel.
"Underground coal gasification has the potential to slash coal's environmental impacts... it could be game changing technology for addressing climate change"
- John Thompson
director of the coal transition program at the Clean Air Task Force
