The use of solar energy for heating greenhouses in the cold period for a Mediterranean climate is an important issue. In this paper, the thermal performance of a new solar air heater using a packed bed of spherical capsules with the latent heat storage system in east–west oriented greenhouse,...

A very common problem in solar power generation plants and various other industrial processes is the existing gap between the period of thermal energy availability and its period of usage. This situation creates the need for an effective method by which excess heat can be stored for later use....

This paper reviews the development and application of energy saving latent heat storage phase change materials (PCMs) and environmental friendly humidity-controlled materials for indoor thermal management and humidity control. Based on the studies reported in the literatures, we indicated that...

The present research explains and analyses a technically feasible and economically profitable alternative for concentrated solar power plants recently constructed in Spain. The proposed solution is hybridization with biogas. The method is more economical than investment in salt storage systems,...

The paper reviews different approaches, technologies, and strategies to manage large-scale schemes of variable renewable electricity such as solar and wind power. We consider both supply and demand side measures. In addition to presenting energy system flexibility measures, their importance to...

Wind energy is inexhaustible renewable. Unlike conventional fossil fuels, wind energy is clean, abundant energy that will be available for future generations. However, wind speed is a highly stochastic component which can deviate very quickly. Output power of the wind energy conversion system...

In future electricity systems with a high share of intermittent renewable power generation, battery technologies have the potential to support power quality and security. The growing scientific literature on batteries reflects the high attention that currently rests on these technologies. This...

The microgrid concept has been closely investigated and implemented by numerous experts worldwide. The first part of this paper describes the principles of microgrid design, considering the operational concepts and requirements arising from participation in active network management. Over the...

The growing economy with corresponding increase in power demand causes more challenges in power sector of developing countries. In India, the increase in peak power demand necessitates energy storage schemes over and above the storage—hydro-, oil- and gas-based peak power plants to ensure...

The use of ammonia-based working fluids for absorption prevails in a wide range of applications due to the low freezing temperature of the refrigerant and the absence of crystallization as well as the lack of problems under vacuum conditions. This paper presents a comprehensive overview on the...
