Prudent and efficient utilization of renewable energy sources is needed in order to achieve clean energy transition. Since energy use in buildings represents around 40% of total energy use in European Union the reduction of energy use in this sector is most definitely needed. One of the great challe ...

V doktorskem delu smo obravnavali celostne masne, energijske in okoljske vplive v fazi uporabe nizkotemperaturnih gorivnih celic s protonsko izmenjevalno membrano (NT PEMFC). V ta namen smo raziskali mehanizme degradacije komponent membransko elektrodnega sklopa in izvedli ciljne pospešene degradaci ...

Climate changes are already here. And they will get much worse in time. The main reason for global warming is GHG emissions from anthropological sources. That includes transportation, industry, electricity production, agriculture, and others. The European Union has introduced a new Green Deal as an ...

In the building sector, 40% of final energy is used for heating and cooling. Up to 75% of this is used in res-idential buildings. It is necessary to take a step forward and reduce this share of energy consumption, inparticular through the use of efficient technologies and their integration into the ...

In this paper an environmental impacts of a 3 kW uninterruptible power supply system with polymer membrane fuel cell (FCH-UPS) was evaluated with a life cycle assessment (LCA) method. The analysis was focused on the analysis of the end of life (EOL) scenarios that will help to reduce environmental i ...

Although proton exchange membrane fuel cell (PEMFC) systems are expected to have lower environmental impacts in the operational phase, compared to conventional energy conversion systems, there are still certain economic, operational, and environmental setbacks. Durability under a wide range of opera ...

When considering the deployment of renewable energy sources in systems, the challenge of their utilization comes from their time instability when a mismatch between production and demand occurs. With the integration of thermal storages into systems that utilize renewable energy sources, such mismatc ...

To support the energy transition in the area of defence, we developed a tool and conducted a feasibility study to transform a military site from being a conventional energy consumer to becoming an energy-positive hub (or prosumer). Coupling a green energy source (e.g., photovoltaic, wind) with fuel ...

The EU-funded project eGHOST supports the fuel cells and hydrogen (FCH) industry in shaping the eco (re)design of hydrogen-related products such as proton exchange membrane fuel cell (PEMFC) stacks. Within this framework, a life cycle sustainability assessment (LCSA) of a PEMFC stack was conducted t ...
