Abstract
In this paper, we present the economic analysis of a solid-oxide fuel
cell (SOFC) micro-cogeneration plant in a single-family low energy house in
Finland. Here, we implement a new solid-oxide fuel-cell (SOFC) model in the
dynamic building simulation software IDA – Indoor Climate and Energy to obtain
the match between energy demand and supply. In our computational study, we
first estimate the break-even values for both the buyback price of electricity
and plant investment that make an SOFC plant financially viable in a
comparison with a water-based gas boiler heating system without cogeneration.
Second, we determine the sensitivity of break-even prices in terms of the
electrical power, overall efficiency and two operational strategies. Our
results suggest that the optimal operation would encompass a constant run with
electrical power no more than 1 kWe. In the above case, the break-even
buyback price would remain less than 0.04 EUR/kWh, provided that the overall
efficiency exceeds 80 %
