Abstract:
As part of ECN's in-house R and D programme on high-temperature fuelcells (MCFC and SOFC), system integration of solid oxide fuel cells with
small advanced gas turbines for the Dutch combined heat and power market have
been assessed, in order to determine whether this could enhance the
competitiveness of fuel cell systems. Thermodynamic computations by means of
the advanced flow sheeting program ASPEN PLUS"T"M indicate that the
integrated fuel cell advanced gas turbine CHP system can achieve electrical
efficiencies up to 70% (LHV) and total efficiencies up to 84% (LHV). The
higher electrical efficiency of the hybrid system, compared with SOFC systems
alone, allows an increase in the investment costs of about 40%, which is more
than the additional investment required for the advanced gas turbine. Thus,
the integration of solid oxide fuel cells with small advanced gas turbines
will enhance the competitiveness of SOFC systems in the CHP market. 2 figs.,
