Confronting Nationally Determined Contributions to IPPC’s +2°C Carbon Budgets through the Analyses of France and Wallonia Climate Policies
01 juin 2023, HE de la Province de LiègeArticle scientifiqueA method to objectively compare and link climate policies, expressed in CO2eq, to IPCC’s carbon budgets, expressed in CO2-only, is exhibited, as countries often omit to so in their Nationally Determined Contributions. Furthermore, they are usually pledging only towards territorial targets despite the fact that imported emissions are now greater in occidental countries, thus relying on the countries ... -
Developing individual carbon footprint reduction pathways from carbon budgets: Examples with Wallonia and France
23 avril 2024, HE de la Province de LiègeArticle scientifiqueTraditional climate strategies focus on long-term emissions targets, neglecting cumulative CO2 emissions and often limiting their scope to territorial emissions. Additionally, individual citizens struggle to connect with community targets. This study addresses these issues by computing a comprehensive carbon footprint pathway that, as a main contribution, can be easily personalized and associated ... -

Experimental assessment of pollutant emissions from residential fuel cells and comparative benchmark analysis
07 mai 2024, HE de la Province de LiègeArticle scientifiqueEnergy transition currently brings focus on fuel cell micro-combined heat and power (mCHP) systems for residential uses. The two main technologies already commercialized are the Proton Exchange Membrane Fuel Cells (PEMFCs) and Solid Oxide Fuel Cells (SOFCs). The pollutant emissions of one system of each technology have been tested with a portable probe both in laboratory and field-test configurations. ... -
Experimental investigation and modelling of a Solid Oxide Fuel Cell (SOFC) used in residential cogeneration applications
18 septembre 2024, HE de la Province de LiègeArticle scientifiqueThe much-needed energy transition brings special focus on fuel cell micro-combined Heat and Power (mCHP or micro-CHP) systems for residential uses, one of which is a Solid Oxide Fuel Cell (SOFC), fed by natural gas, designed to provide continuously 1.5 kWel with an associated amazingly high expected Low heating Value (LHV) electrical efficiency of 60%. This power output can be modulated as desired ... -
Field-test performance models of a residential micro-cogeneration system based on the hybridization of a proton exchange membrane fuel cell and a gas condensing boiler
10 septembre 2023, HE de la Province de LiègeArticle scientifiqueThe energy transition brings focus on cogeneration systems, even at residential levels. One of the latter systems consists in a proton exchange membrane fuel cell (PEMFC) combined with a gas condensing boiler and a 220L domestic hot water tank. The system, fed by natural gas, is designed to provide the heat demands of residential houses and to participate locally in the electrical produc-tion thanks ... -
