Abstract:
The results of an environmental life cycle assessment of a 250 kWExternal Reforming Molten Carbonate Fuel Cell (ER-MCFC) power plant are
presented. The aim of this investigation is to determine environmental
aspects of (1) lifetime extension of the stack and (2) efficiency
improvement. Shortcomings of the allowed procedure for life cycle assessments
are pinpointed in the field of the software package, the inventory and the
normalization of effect scores or classification as well as evaluation. Life
extension of the stack from 7,000 to 42,500 hours results in a decrease
(5-80%) of all environmental impacts considered in this study. A 6%-point
efficiency improvement of the power plant to 50% reduces all environmental
impacts by 12%. Efficiency improvement in combination with lifetime extension
of the stack leads to a decline of environmental pollution by about 20-80%. 7
