To enhance reliability of the electric grid while simultaneously incorporating renewable power sources into it, there is a pressing need for electrical energy storage, to increase the capability for dispatch and to accommodate the variable nature of those resources. There is, at present, very little energy storage on the grid, due in part to the high capital costs associated with electrochemica...

The feasibility of inertial energy storage in a spacecraft power system is evaluated on the basis of a conceptual integrated design that encompasses a composite rotor, magnetic suspension, and a permanent magnet (PM) motorlgenerator for a 3-kW orbital average payload at a bus distribution voltage of 250 volts dc. The conceptual design, which evolved at the Goddard Space Flight Center (GSFC), is...

In the present work,MoS2 decorated graphene nanocomposite powders were synthesized by laser scribing method.Theobtainedflexible light-scribed graphene/MoS2composites are very suitableas micro-supercapacitors and thus their performance was evaluated at different concentrations.The effect of laser scribing process to reducegraphene oxide (GO) was investigated. The GO/MoS2composite wassynthesized ...

24.1 INTRODUCTION Portable electronics have evolved rapidly over the last 10 years and now wear-able technologies are following the same trend. While multifunctional clothes are appearing on the market with a multitude of electronic devices incorporated onto the fabric, garment devices are articles of clothing with inherent electronic properties. Garment devices are the actual device, a new kin...

Based on this redox mechanism, we developed a series of polyamides with different structures and investigated their electrochemical activity as cathode materials for rechargeable lithium batteries. The results show that the polymer framework endows these samples with excellent cycling stability. Additionally, their capacity and rate capability are also satisfactory. The five polyimides were obt...

Being sustainable and producing little waste products, the renewable energy knows a rapid deployment. Unfortunately, the intermittent characteristic of these energies makes them difficult to control. The influence of this aleatory character can be reduced with the coupling of two or more sources of renewable energy and secondly with a sound management of storage systems. This new configuration ...

The main risks of arising from the using fossil fuels can be referred to environmental pollution, the effects of greenhouse gases, climate change and acid rain. For this reason, efficient use of energy in economic development has always been considered as an important goal of sustainable development. In this study, the effects of time-varying electricity prices in the energy storage components ...

In recent years, climate change and nationally determined contribution (NDC) policies worldwide have accelerated the transition from fossil energy sources to renewable energy. Consequently, storage system (ESS) sector has emerged as an area of increasing importance in this industry. particular, compressed air (CAES), which a long history commercialization, is reappraised competitive ESS technol...
