Summary

In conclusion, the gas turbine represents a cost effective resource for the Balance-of-Plant in the fuel cell system, because of its energy conversion performance and the availability as off-the-shelf equipment The advanced thermal integration features of the Ztek Planar SOFC uniquely facilitate the hybrid system integration with a gas turbine. With the hybrid system integration, the Ztek Planar SOFC and gas turbine can mutually enhance the favorable characteristics of cost, efficiency, package flexibility, and environmental performance for distributed generation.

Studies of near-term applications of Ztek's SOFC technology, by year 2000, indicate that systems in the capacity range of sub-MW to 10MW offer ultra-high efficiency of more than 70% for pressurized SOFC/Gas turbine systems. Ztek plans to provide Distributed Generation products to customers at a system price below $900/kW. It is expected that the Cost-of-Energy of these units can approach 4 Cents/kWh.

The Ztek Planar Solid Oxide Fuel Cell Technology has been developed under cost sharing of corporate funds and contracts with the Tennessee Valley Authority, the Electric Power Research Institute, the U.S. Department of Defense and the U.S. Department of Energy.
