Switzerland field tests

A self-supporting SOFC-based power plant system, HEXIS (Heat Exchanger Integrated Stack), using circular planar elements has been developed by the Sulzer company in Switzerland for natural gas as a fuel and a power of up to 7 kW [26]. Field tests have started in summer 1997 commercialization is planned for the year 2002. The development goal is the construction of small-size systems in the power range of 1 - 200 kW.

Recently migrating corrosion inhibitors have been proposed as surface applied liquids (Mader, 1994). It is claimed that the inhibitor will migrate both in the gas and in the liquid phase to the reinforcement. The results reported are conflicting a recent laboratory study on precorroded (both chloride induced and carbonated) mortar samples showed practically no effect in reducing the corrosion rate even after several immersion cycles in the inhibitor solution (Elsener et al., 1999b). Despite some field tests (Laamanen et al., 1996) and an increasing number of applications, very few documented and conclusive results exist on the inhibitor efficiency. A first field test with different surface applied inhibitors on a well characterized and instrumented side wall of a tunnel started in Switzerland in 1998. 

Sulzer Hexis started its SOFC development in 1989 [53,54], In the period 1989-1997, two proof-of-concept systems were demonstrated in Winterthur, Switzerland, at Sulzer Hexis facilities and in Dortmund, Germany (Dortmund Energy and Water utility company DEW). This proof-of-concept phase was followed by a field test on six customer sites in Switzerland, Japan, the Netherlands, Spain and Germany. Together, these field test units accumulated 65,600 operating hours. The field test phase was finished in 2000 and currently the market entry phase has started. Sulzer Hexis has orders for more than 400 of its HXS 1000 Premiere fuel cell units. The customers are utility companies, mainly located in Germany, Austria and Switzerland. Systems will be delivered from 2003 onward [55], Sulzer Hexis expects to sell 10,000 units in 2005 and to increase annual sales to 260,000 units by 2010. 

As part of the DECOVALEX III project, several independent research teams have used various numerical models to analyze a full-scale engineered barrier experiment (FEBEX), currently conducted at the Grimsel Test Site in Switzerland. This paper presents the analysis conduced by the Berkeley Lab research team, using the fully coupled thermal-hydrological-mechanical (THM) numerical model ROCMAS. Specifically, the paper presents model predictions of coupled THM responses at FEBEX that are compared to field measurements.
