Making Coal Relevant for Small Scale Applications: Modular Gasification for Syngas/Engine CHP Applications in Challenging Environments
The proposed project includes construction and operation of a power plant consisting of coal gasification facilities and engine generators which would produce electrical power and heat. The recovered heat and a portion of the carbon dioxide emissions from the engines would support an onsite greenhouse and other heat and power customers. The proposed project site is located on the Marathon North Pole Terminal property in North Pole, Alaska. Two gasifiers would convert the coal into syngas, which would be fed through a gas cleanup train and then combusted in six reciprocating engines driving electric generators. Heat recovery on the engine cooling loops and exhaust trains would provide heat to a glycol/water circulation system for use in the greenhouse, in the Marathon facilities and for other customers. Natural gas would fuel two additional engine generators and would also be available to supplement the syngas-fired engines.
