Energy storage technologies will play a crucial role in increasing both the efficiency as well as the availability of renewable energy. Compressed Air Energy Storage (CAES) enables the efficient and cost effective storage of large amounts of energy–usually above 100 MW.However, this technology is limited by the inherent risks of underground exploration. In order to reduce this handicap, we propose...
Different configurations of a 100% renewable electricity system are possible, but not all are equally desirable in terms of the scale of material resources required to sustain them. This study compares different approaches for developing a 100% renewable electricity system on the basis of the material mass investment required to sustain their physical components. Electric grid modeling accounting...
Achieving greenhouse gas reduction targets requires an increased share of renewable energy sources in todays energy systems. The spatial and temporal mismatch between electricity supply and consumers demand arising from fluctuating renewable electricity generation can be overcome by energy transport and storage. Here, one option is the Power-to-Gas concept. With this, hydrogen is produced by water...
Smart grids are a concept which is evolving quickly with the implementation of renewable energies and concepts such as Distributed Generation (DG) and micro-grids. Energy storage systems play a very important role in smart grids. The characteristics of smart cities enhance the use of high power density storage systems, such as SMES systems. Because of this, we studied the possibility of adapting these...
This paper presents a model for scheduling an energy hub (EH) whi ch supplies electricity, heat and cooling demands and manages continuous and on/off controllable appliances. The characteristics of EH components such as energy loss and depreciation cost of electrical, heat and cooling energy storages, as well as the feasible operation region of combined heat and power units are modeled in detail....
Climate targets set by international organizations require the implementation of innovative technologies that ensure the decarbonization of energy sector. It may be partially achieved through a large penetration of Renewable Energy Sources. Massive energy storage is essential to handle excess electricity associated to RES and Power-to-Gas represents a promising option to chemically convert electricity...
Efficient latent heat thermal energy storage (LHTES) systems can be potentially employed to improve the energy saving capability and thermal performance of buildings. In this paper, a new coupled cooling method with phase-change chairs (PCC) and phase-change plates (PCPs) is firstly proposed to solve the cooling problem in isolated environments, such as mine refuge chamber with high temperature. A...
Multi energy system is considered an effective pattern to improve the energy efficiency and reduce energy supply cost by integrating multi energy carriers. Face abundance energy convertor and storage devices with various characteristics, how to select the types and capacities of devices, how to connect and manage the selected devices are core challenging problems to design the optimal structures of...
The growing energy demands has led to a soaring level of greenhouse gas (GHG) production, with the implementation of EU legislations, the production of GHG and waste is being curbed but with an economic disadvantage. Multiple industries face losing their competitive edge due to the restrictions currently in place due to the inability to readily burn fossil fuels. With developments of thermal and physical...
