Tognum Announces Orders for Gas Engine and Fuel Cell Systems

Posted on May 28, 2009

Tognum has further expanded its business in the decentralized energy generation sector in Germany with the announcement that the municipal utilities in the towns of Wolfen and Weimar are each to be supplied with a combined heat and power plant this year. These will be the first MTU Onsite Energy systems in Germany to use 20-cylinder MTU Series 4000 gas engines.

The Type GC 2145 N5 power stations will be used to generate both electricity and heat. Each produces 1999 kW of electrical and 2206 kW of thermal output. Apart from the CHP modules themselves, the contracts also extend to all connecting systems – not only switchgear and engine technology but heating, exhaust and ventilation systems. Several municipal utilities in Germany’s eastern states are currently planning to install combined heat and power generation systems or to renew older installations. The two contracts in Wolfen and Weimar will thus serve as important reference projects for potential follow-up orders.

Another contract in the decentralized energy generation sector, this time in the fuel-cell sector, has been received from the Giessen-Marburg University Hospital. An MTU Onsite Energy fuel cell will supply the hospital with energy beginning in 2010. The contract is worth nearly US$2.7 million. The Type HM400 (HotModule) natural-gas fuelled fuel cell is capable of an electrical output of 345 kW and a thermal output of 230 kW. It is the most powerful such plant so far supplied by MTU Onsite Energy. Compared with its predecessors, it has an increased performance of around 45 percent. The hospital can use the thermal energy recovered at around 400 degrees Celsius not only for heating but for cooling as well. That is achieved by passing the heat through an absorption chiller. Combined operation is also possible.

The plant in Giessen-Marburg represents the third fuel cell installed by Rhön-Klinikum AG for one of its hospitals. The company previously ran a plant as a pilot project at its medical facility in Bad Neustadt from 2001 to 2004. Its second HotModule has been in operation in Bad Berka since 2003.
