Chementator: Hybrid power plant

By Chemical Engineering |

Energie Baden-Württemberg AG (EnBW; Karlsruhe) and Siemens Power Generation (Erlangen, both Germany; edlinks.chemengonline.com/6517-550) are joining forces to build a fuel-cell hybrid power plant with 70% efficiency (fuel to electricity) and a megawatt-scale power output. The 70% efficiency of this hybrid process — combining a high-temperature fuel cell with a gas turbine — is significantly higher than the approximately 60% achieved by modern gas- and steam-turbine power plants, says Siemens. In the first phase (three years) of the project, Siemens will supply a 5-kW, high-temperature solid-oxide fuel cell (SOFC) that will be used for developing an operating concept, the simulation model and a control concept. From 2009 to 2012, test components will be coupled together and the configuration optimized. Construction of a 1-MW hybrid fuel cell plant is to begin in 2012.   Click here for a full pdf version of the Chementator Section
