Alaska low-rank coal-water fuel diesel demonstration project

A Coal-Water Fuel (CWF)-Diesel Demonstration Project developed by ADLittle (ADL) and Cooper-Energy Systems (CES) was selected for funding in US Dept. of Energy`s (DOE`s) Clean Coal Technology Program (CCT). The $38.3 million demonstration was originally planned for a utility in Maryland using CWF made from cleaned Ohio bituminous coal. When the host utility withdrew from the project, the sponsors sought a new location. During this time the technical feasibility of producing a premium low-rank coal-water fuel (LRCWF) from hydrothermally treated (HT) ultra-low S Alaskan subbituminous coal had been demonstrated at the pilot-scale. Since preliminary cost analyses showed Alaskan LRCWF to be competitive with Chinese bituminous CWF and oil priced at about $18 per barrel, an Alaskan consortium was seeking funding for a commercial-scale LRCWF demonstration project proposed for the University of Alaska Fairbanks (UAF). Since the engine developers at CES were already familiar with the features of LRCWF, the projects were combined and DOE approved relocating the LRCWF-Diesel CCT Project to UAF. The combined project will feature a 6.3 MWe diesel generation set with advanced emission controls capable of operating with either LRCWF or diesel, an oil-designed boiler also modified to use LRCWF or oil, and a nominal 120 tpd LRCWF production plant. Key project objectives are to develop commercial-scale LRCWF production costs, determine derating requirements and deratings for oil-designed boilers fired with LRCWF and to operate a LRCWF-fired diesel engine long enough to establish operating and wear characteristics.
