"The renewed concern for the care of the environment has led to lower emissions of greenhouse gases without sacrificing modern comforts. Widespread proposal focuses on energy produced from renewable sources and its subse...

"This paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen ...

"Four nickel-based catalysts are synthesized by wet impregnation and evaluated for the hydrotreatment/hydrodeoxygenation of beech wood fast-pyrolysis bio-oil. Parameters such as elemental analysis, pH value, and water c...

"The transition to renewable energy sources is reshaping energy systems globally. Germany is a leading example of this shift, having significantly increased its renewable energies (RE) generation in recent years, particu...

"The aim of this project is to study the use of energy surplus from local renewable sources at isolated places in Argentina, to produce electrolytical hydrogen as clean fuel for electricity generation. Furthermore, the h...

The main objective of the study is to present a comprehensive and, above all, updated overview of the hydrogen demand and supply situation. The physical and chemical properties of hydrogen are presented, together with an...

"This thesis evaluates the technical, economic and environmental performance of a hydrogen fueled hybrid bus, which uses an internal combustion engine as a power unit. Results are compared to those of a conventional dies...

The European demonstration fusion power plant (EU-DEMO) project intends to prove the commercial viability of nuclear fusion as a source of safe and clean energy. This fusion power plant will be fueled by a 1:1 deuterium-...

"The on growing global energy demand and the increasing need to reduce greenhouse gas emissions in order to avoid the worst case scenarios of global warming, forces to introduce cleaner and more sustainable technologies ...

In order to increase the flexibility of renewable energies and improve their integration into existing energy grids, efficient intermediate storage is necessary. High-purity hydrogen produced in a water electrolysis cell...

With the increasing relevance of energy transition, synthetic fuels have arisen as an alternative to storage green energy. In the processing of this fuels, carbon monoxide is widely used. Understanding the behaviour of t...

"En el trabajo se expone el concepto de generación distribuida de energía con sistemas que combinan aerogeneración y producción de hidrógeno mediante electrólisis de agua. Se estudia el dimensionamiento óptimo de ...
