Installation of fuel cell-based cogeneration systems in the commercial and retail sector: Assessment in the framework of the {COMSOS} project
This work studies the technical and economic feasibility of the introduction of a SOFC-based cogeneration system
to supply non-residential buildings with electricity and heat. The techno-economic evaluation is performed for
the hotel and hospital sectors, by introducing real hourly load profiles (electrical and thermal) for the buildings.
The analysis considers different countries in terms of energy intensity (and load profiles), cost of energy and
regulations/incentives. Results are achieved by comparing the SOFC scenario with a benchmark one where
electricity is supplied by the grid and heat by a natural gas fed boiler and evaluating the relative payback time
between the two solutions.
The analysis showed that, despite the current high investment cost of the SOFC system, in countries such as
Germany, Italy and UK (where electricity prices are among the highest in Europe), the option is yet advisable if
supported by effective subsidies (already existing for cogeneration systems), and it could offer a competitive
alternative to traditional systems, especially in the hospital sector, where the relative payback time is achieved in
the 10th year for UK, and in the 14th year for Germany and Italy. A cost reduction scenario has also been
analyzed: results show that the SOFC is the best option in most of the locations, both economically and in terms
of environmental impact (pollutants emissions reduction)
Electrochemical promotion of IrO2 catalyst for the gas phase combustion of ethylene
The catalytic activity of IrO2 catalyst films for the gas phase combustion of ethylene can be increased by up to a factor of 10 via anodic polarization of the IrO2 catalyst relative to a Au electrode both deposited on Y2O3-stabilized ZrO2 solid electrolyte. The steady-state increase in the catalytic reaction rate is typically 200 higher than the expected rate increase of ethylene combustion calcd. from Faraday's law. This is the 1st demonstration of the effect of nonfaradaic electrochem. modification of catalytic activity (NEMCA) using a metal oxide catalyst. [on SciFinder (R)
