Making Coal Relevant for Small Scale Applications: Modular Gasification for Syngas/Engine CHP Applications in Challenging Environments
The overall objective of this project is to demonstrate the potential for small-scale, modular, coal gasification units to provide low-cost fuel for firing diesel engine generators with syngas and pyrolysis tars/oils, first in the Fairbanks area, then in the villages. By coupling the gasifier with a diesel engine, the syngas/engine combination can be used in baseload and non-baseload applications and in distributed generation applications. Through modularization of the components of this system, the manufacturing and construction costs could be lowered so that syngas/engine modular systems could become competitive with similarly sized power generating plants operating with conventional technology.
There are no less than 30 villages with coal nearby, yet it goes unused. For most of Alaska’s villages, diesel electric plants are the only viable option for power generation. Such plants and the accompanying infrastructure such as bulk fuel facilities are readily adapted to most any locality, and they are omnipresent throughout rural Alaska and the developing world. This project, if successful, could displace bulk diesel, yet allow continued use of the diesel engine infrastructure already in place. This project has already expended $3 million in design. All that remains is to acquire air permits and raise the capital to build this demonstration plant. Originally intended to repurpose UAF’s Atkinson Power Plant, the new demonstration sight is within the City of North Pole. The syngas plant will sell power into the GVEA grid for about 9¢/kWhr, and provide hot water or steam heat at $12/MMBtu for the City’s build out of their water treatment system.
