Gas engine and fuel cell CHP systems for Germany

The municipal utilities in the towns of Wolfen and Weimar in Germany are each to be supplied with a CHP plant from propulsion and power solutions company Tognum. The stations will be used to generate both electricity and heat ” each produces 1,999 kW of electrical and 2,206 kW of thermal output. And, apart from the CHP modules, the contracts extend to all connecting systems, including switchgear and engine technology, heating, exhaust and ventilation systems.

They will be the first MTU Onsite Energy systems in Germany to use 20-cylinder MTU Series 4000 gas engines.

Several municipal utilities in Germany’s eastern states are currently planning to install CHP generation systems or to renew older installations, says Tognum, so the two contracts in Wolfen and Weimar will thus serve as important reference projects for potential follow-up orders.

Meanwhile, Tognum has received another contract in the decentralized energy generation sector, this time for fuel cell technology, from the Giessen-Marburg University Hospital. An MTU Onsite Energy fuel cell will supply the hospital with energy from 2010. The contract is worth nearly €2 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 and, compared with its predecessors it has an increased performance of around 45%, says Tognum.

The hospital can use the thermal energy recovered at around 400à‚°C not only for heating but for cooling as well, by passing the heat through an absorption chiller. Combined operation is also possible, so that while the clinic is using the thermal energy for heating, the cooling function can be employed for air conditioning. And. if the hospital should not require the total amount of heat or cooling energy produced, it has the option of diverting the surplus into the relevant grid operated by the Giessen municipal utility company.

The plant in Giessen-Marburg represents the third fuel cell installed by Rhàƒ¶n-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.
