The transition to low-carbon emitting technologies provokes an increasing demand in energy conversion and storage systems such as fuel cells, batteries, supercapacitors, consequently, the need for their raw materials. use of new chemistries from earth-abundant precursors instead scarce, toxic, nondegradable components existing current must be a priority future years. Cellulose is most abundant ...

Climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. Climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...

many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...

In this paper, a new strategy based on a dynamic (time-based) model is proposed for expansion planning of electrical energy distribution systems, taking into account distributed generation resources and advantage of the techno-economic approach. In addition to optimal placement and capacity, the proposed model is able to determine the timing of installation / reinforcement of expansion options....

Smart devices have pervaded our society and encouraged lifestyles that depend on them. One of the fundamental requirements for a successful dependency is that the general public be aware of the energy limitations of these devices and to stay in control of energy consumption. In this paper, the authors propose a formal specification method that takes energy into account. They propose two develop...

The deployment of multi-carrier energy systems, which are called energy hubs, is one of the most recent and useful strategies in the field of energy systems. The reliability of energy systems and their operation cost and efficiency could be improved by applying the concepts of energy hubs. The simultaneous management of electrical consumptions and heat demands by the concepts of energy hub woul...
