LG Fuel Cell Systems, Inc. will deploy a 250kW rated product demonstrator on a site provided by Stark State College in North Canton, Ohio where the system will operate on natural gas and connect directly to the electric grid. The product-like prototype SOFC power system will incorporate current technologies and operate under a range of environmental conditions for at least 5,000 hours to assess progress of system durability, performance, and operating cost toward commercial readiness. Specific work includes assembling a fuel cell vessel rated for 250kW; assembling and packaging a generator module and balance-of-plant packages; installing and connecting the power system packages and connection to the fuel supply and power grid; commissioning and shakedown testing to validate assembly and safe operation; and at least 5,000 hours operation at a baseload power rating of 250kW net power to the grid. In addition, a stack cost model developed and updated under earlier DOE programs will be updated based on the technology and processes used in this commercial readiness demonstration test.
