nowadays, electricity is one of the most significant infrastructures required for economic development of countries. hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. the majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...

in many hydroelectric dams, when the inflows are greater than the demand for energy, a portion of the water that could be used to generate electricity is diverted to the spillway and literally wasted. this energy,designated as “spilled turbinable energy”, could be used advantageously to generate other products or an energy vector that could be stored for later use, since in these situations the...

In this paper, a novel integrated system that combines photocatalysis, photovoltaics, thermal engine and chemical energy storage for better solar energy harvesting is assessed using energy and exergy methods. The system generates hydrogen and sulfur from sulfurous waters specific to chemical and petrochemical industries. The solar light is split into three spectra using optical surfaces covered...

The possibility of a future economy based on H2 and fuel cells is both promising and uncertain. As a consequence, in the US and in the EU significant actions, with similarities as well as differences, related to hydrogen R&D are being undertaken. Efforts are focused in both cases primarily on applied research, development and demonstration. Some striking differences result from the leading role...

The uncertainty and volatility of renewable energy generation lead to large amounts abandoned electricity. electricity-hydrogen coupling microgrid (EHCM) consists the proton exchange membrane electrolytic cell (PEMEC), liquid organic hydrogen carrier (LOHC) storage, fuel (PEMFC). structure helps increase utilization wind photovoltaic power. scheduling an EHCM is very challenging. This paper pro...

the increasing consumption of electricity in iran is one of the greatest concerns of the government. using the subsidy-based pricing system is one of the main reasons of improper pattern of residential electricity consumption that has imposed great cost over the government due to the increased number of consumers and their improper way of consuming electricity. in this paper, we analyze the fac...

Biofilms of natural anaerobic microbial consortia externally grown on Gas Diffusion Electrodes (GDL) in a bioreactor, were investigated within a MembraneElectrode-Assembly with respect to lifetime and electricity production upon variation of biodegradable materials with an oxygen demand of 1000mg/l as simulated waste water. A remarkable differentiation and plasticity of the films is observed, t...

The construction and behavior of a system exhibiting all-or-nothing propagation of an electrochemical disturbance are described. Detailed measurements of the distribution of electric current and potential are given and the device is compared with nerve and with the Lillie model in respect to structure, electrical and chemical activity, and energy relationships.

Abstract Self-sufficiency (SS) of buildings with low greenhouse gas (GHG) emissions can be obtained using photovoltaics (PV). To maximize self-consumption - minimizing the import grid electricity PV coupled a hydrogen storage system converting to by electrolysis during summer season, when on-site production is higher, and it winter season fuel cells. This article deals sizing constraints solar ...

Fuel cell is an emerging technology in the field of renewable energy sources which has the capacity to replace conventional energy generation sources. Fuel cell utilizes hydrogen energy to produce electricity. The electricity generated by the fuel cell can’t be directly used for a specific application as it needs proper power conditioning. Moreover, the output power fluctuates with different op...
