Reducing environmental impacts of a Ups system based on polymer membrane fuel cell with circular economy [Elektronski vir]Stropnik, Rok ; Sekavčnik, Mihael ; Mori, MitjaIn this paper an environmental impact of a 3 kW UPS system with hydrogen technologies (HT-UPS) was evaluated with a life cycle assessment (LCA) method. The analysis was focused on the development of ... end of life (EOL) scenarios that will help to reduce environmental impacts during manufacturing stage. Numerical model of the HT-UPS was developed using Gabi software. The scope of analysis was cradle-to-grave with functional unit 1 kWh of produced electrical energy. In operating phase hydrogen is produced with electrolysis on site at two geographical locations. Three EOL scenarios were used in the study. With realistic EOL scenario in average a 68% reduction of all environmental impacts in the manufacturing phase was achieved, while a 74% reduction of GW emissions with was achieved with a feasible EOL scenario. EOL phase of HT-UPS represents low environmental impacts compared with other phases of LCA. Finally results show that with recycling and reuse of the materials in HT-UPS a 20% reduction of environmental impacts can be achieved in entire LCA.Vir: Environmental management and impact assessment [Elektronski vir] : (conference proceedings) (2017, Str.
