Abstract :
[en] In order to ensure that we do not overcome the IPCC (Intergovernmental Panel on Climate Change) 2018-2100 carbon recommendations [1] in the few years to come and that we manage to limit global warming to 2°C above pre-industrial levels as agreed upon in the “Paris Agreement” [2], tremendous efforts and investments have to be made. That is why special focus is currently brought on fuel cell micro-CHP systems for residential uses. One of the latter systems, investigated in this study, is a PEMFC-gas boiler hybrid system, fed by natural gas, designed to provide all the heat demands of residential houses and to participate locally in the electrical production. Thanks to high integration levels, it combines the same PEMFC of nominal constant power of 0.75kWel and 1.1kWth with the same 220L DHW (Domestic Hot Water) tank. The gas boiler, mainly used for peak heat demands, has to be chosen between four rated power versions from 11.4 to 30.8kWth. The machine is never electrically driven.
This study is monitoring two of those installations in residential houses in Belgium. It focuses on the comparison of the actual field test performance with the targets expected for this technology.
Since the financial incitant represents a major factor in the investor’s decision towards such a needed technological change, focus is brought on an economic indicator based on an average Belgian household energy bill. Through a quite thorough analysis of emissions factors used by recognized organizations, ecological indicators are established with current emissions factor assumptions in an attempt to foresee the place of this micro-CHP technology in the energy transition challenge of today towards the carbon neutral future that everyone should aim for.
The methodologies for calculating those indicators are quite exhaustively described as they represent key parameters in the results drawn in this paper.

Commentary :
In this publication, energy consumption (established thanks to the gas volume that has been consumed and the HHV figures given by the gas provider) could be refined with S-GERG 88 (or similar) method. This would lead to different ecological and economical indicators for the systems even if the trends shown in this paper would remain. That is why this paper is only offered in private access. Please check the ECOS 2022 paper to have a similar updated and more relevant study.
