Siemens Westinghouse to provide European utilities with hybrid fuel cell plant

ORLANDO, Fla.à‚–(BUSINESS WIRE)à‚–Dec. 6, 2000à‚–The Siemens Westinghouse Power Corporation (SWPC) today announced that it has entered into a Consortium Agreement with four key European Utilities to provide the first MW scale Hybrid Plant to be demonstrated as a pre-commercial plant for the European market.

The system will be based on the tubular solid oxide fuel cell (SOFC) technology. The project will be funded under the Framework Five Program of the European Commission and also as part of the DOE Cooperative Development Agreement that Siemens Westinghouse has with the US Department of Energy (DOE). This program will be the largest demonstration in Europe of the Siemens Westinghouse Tubular Solid Oxide Fuel Cell Technology.

Energie Baden – Wurttenberg AG (EnBW), headquarters in Stuttgart, Germany, will be the host utility and the Program Manager for this strategic demonstration project. Also, the French national utilities Electricite’ de France and Gaz de France, both located in Paris, will participate in providing and coordinating the MicroTurbine and the Balance of Plant system along with Tiroler Wasserkraftwerke Antiengesellschaft (TIWAG) a major power utility of Innsbruck, Austria.

These key utilities will work with Siemens Westinghouse and Siemens AG to build this first of a kind 1 MW system in Europe. The system will be located at an EnBW facility in Marbach, Germany. The 1 MW Pressurized Hybrid System will feature a scale up of Tubular Solid Oxide Fuel Cell Generator Module.

The Generator Module will be integrated with a microturbine generator that will provide 20% of the electricity produced. The 1 MW system, which will have electrical efficiencies approaching 60% and will be connected to the EnBW utility grid. The system is to be in operation by October 2003 and will operate for a period of at least 12 months. Key objectives of the project are to gain experience with operating characteristics and to qualify SOFC system designs to European Codes and Standards.

“The Generator Module will be built at Siemens Westinghouse’s SFC facility in Pittsburgh, Pennsylvania and will be shipped to the EnBW facility for integration with the microturbine and the balance of plant subsystems. All other subsystems such as the microturbine generator, DC-to-AC inverter, etc., will be provided by the Consortium Utilities,” said Thomas Voigt, recently appointed President, Siemens Westinghouse Stationary Fuel Cells. “We are pleased to finally have everything in place to begin this key strategic program,” he said.

“In Europe, this system can be the forerunner of a new class of systems that can be used for a variety of Distributed Generation applications and can be located close to customer loads,” said Allan Casanova, Director of Business Development for Stationary Fuel Cells. “When commercial, we expect these high efficiency systems, that are environmentally friendly, to be competitive with other technologies and products being applied today for similar Distributed Generation Application,” said Casanova.

Siemens Westinghouse plans to commercialize SOFC systems by 2004 with first commercial deliveries in the 250 kW to 1000 kW range. Included in these systems will be simple cogeneration systems of 250 kW, and Hybrid Systems of 300 kW and 1000 kW utilizing the SOFC with a microturbine.

These hybrid systems, like the one being demonstrated in Marbach, are aimed at the all-electric market segments, where hot pressurized SOFC exhaust drives a microturbine generator, and thereby achieves unprecedented electrical efficiencies approaching 60%. The SOFC Hybrid System can also be used for cogeneration applications.

Siemens Westinghouse is developing SOFC technology under a cooperative agreement with the US Department of Energy (DOE) through its National Energy Technology Laboratory in Morgantown, West Virginia.

Siemens Westinghouse Power Corporation is a Siemens Company headquartered in Orlando, Florida. Within Siemens’ global Power Generation business, Siemens Westinghouse is the regional business division for the Americas and operates engineering and manufacturing centers in North America. In the U.S. and Canada, the company also is responsible for the Industrial Turbines, Instrumentation & Control, and Hydroelectric business.
