South Heart IGCC
Great Northern Power Development and Allied Syngas are heading for establishing a lignite fired 175 MW net output IGCC plant, with about 90 percent capture rate of carbon dioxide. The plant will produce 4.7 million Nm3/day of hydrogen for power production.
Will capture 2.1 million tonnes per annum of carbon dioxide transported via pipeline to oil fields for enhanced oil recovery in the Williston Basin, western North Dakota and Montana.
The facility will use three BGL gasifiers and associated downstream process units to convert lignite from the adjacent mine into hydrogen. The hydrogen will be used to fuel a combustion turbine (CT) that will drive a generator to produce electricity. The heat energy contained in the turbine exhaust will be recovered in a heat recovery steam generator (HRSG) that will produce steam used to drive a steam turbine. That steam turbine will drive a second generator. This configuration is commonly referred to as IGCC.
Zoning change to allow a coal mine and gasification plant was granted in April 2010. Additional permits have been applied for.
SHED does not anticipate commencement of construction before July 2013. Were construction to begin in July 2013, SHED projects operation to begin approximately 4 years later in July 2017.
The current estimated cost for the construction of the facility is $2.2 billion.
