The standard solution for the traction system in battery powered electric vehicles (EVs) is a two-level (2L) inverter feeding a three-phase motor. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L...

Amorphous (Ni_0.6Nb_0.4)_1−xZr_x membranes were investigated by means of X-ray diffraction, thermogravimetry, differential thermal analysis and tensile modulus measurements. Crystallization occurs only above 673 K, and even after hydrogenation the membranes retain their mainly amorphous nature....

In this paper we will present an analysis of the current state of practice in project management in the energy sector in Serbia, wherein the mentioned analysis is based on the results of original research on project maturity in this field. This paper includes a literature review about the...

With the development of the smart grid in China, new opportunities for responsive industrial loads to participate in the provision of ancillary services (AS) will become accessible. This paper summarizes AS in China and analyzes the necessary characteristics and advantages of industrial users to...

Decadal to centennial land use and land cover change has been consistently singled out as a key element and an important driver of global environmental change, playing an essential role in balancing energy use. Understanding long-term human-environment interactions requires historical...

Solar energy is a good solution for energy-deficiency problems, especially in regions such ‎as rural areas in the Middle East that have not been electrified yet or are ‎under electrification. In ‎this paper, with the aid of a Computational Fluid Dynamics simulation, we propose a ‎system...

One of the main challenges for widespread penetration of plug-in hybrid electric vehicles (PHEVs) is their impact on the electricity grid. The energy sector must anticipate and prepare for this extra demand and implement long-term planning for electricity production. In this paper, the...

Torrefaction is a thermochemical pre-treatment process for upgrading the properties of biomass to resemble those of fossil fuels such as coal. Biomass properties of particular interest are chemical composition, physical property and combustion characteristics. In this work, torrefaction of beech...

CO₂ injection in hydrate-bearing sediments induces methane (CH₄) production while benefitting from CO₂ storage, as demonstrated in both core and field scale studies. CH₄ hydrates have been formed repeatedly in partially water saturated Bentheim sandstones. Magnetic Resonance Imaging (MRI) and...</sub>

BioCCS is a technology gaining support as a possible emissions reduction policy option to address climate change. The process entails the capture, transport and storage of carbon dioxide produced during energy production from biomass. Globally, the most optimistic energy efficiency scenarios...
