Linc Energy UCG Leases in AK

Summary

An Australian company, Linc Energy, is exploring several sites in Central Alaska and near Cook Inlet, looking into the feasibility of developing one, or more, underground coal gasification (UCG) projects in those areas.

Background on UCG

Underground Coal Gasification (UCG) involves igniting coal in the ground, then collecting and using the gases ("syngas") that result from its partial combustion. Although the idea dates back over a century, very few UCG plants have ever been built. Underground gasification could potentially allow the use of coal that is currently uneconomical to mine. Underground gasification eliminates the need for strip mining, and might make carbon capture and sequestration (CCS) more practical. However, UCG produces more carbon dioxide per unit energy than standard coal-fired power plants. The wastes coal combustion leaves behind can leach pollutants into nearby groundwater, and have caused major contamination in UCG pilot projects.

Linc Energy Leases

In March 2010, the Australian company Linc Energy acquired 123,000 acres of coal and natural gas leases near Cook Inlet. In January 2011, Linc leased an additional 180,000 acres of Mental Health Trust Land for further exploration.

Linc Energy has stated that their primary goal is the generation of electric power, with an additional interest in conversion of the syngas into transportation fuels. 

Current Status

As of Fall 2011, Linc had applied for, and received, permits for exploratory drilling at two sites, one near Healy/Anderson and one on the west side of Cook Inlet near Tyonek.  Drilling at these two sites will consist of a total of five boreholes, at depths of 3000-4000 feet.  By January 2012, drilling had commenced at one borehole, near the Beluga power plant on the west side of Cook Inlet.
