during the last recent decades, restructuring in the electricity industry has been considered as an economical policy. consequently, it was able to increase private investment, competition, efficiency, and productivity. the purpose of restructuring electricity industry is to change electricity industry organization, in order to omit monopoly and increase competition. recognition of restructurin...

A technoeconomic analysis of photoelectrochemical (PEC) and photovoltaic-electrolytic (PV-E) solarhydrogen production of 10000 kg H2 day 1 (3.65 kilotons per year) was performed to assess the economics of each technology, and to provide a basis for comparison between these technologies as well as within the broader energy landscape. Two PEC systems, differentiated primarily by the extent of sol...

Microbial electrolysis cell (MEC) is one of the promising and cutting-edge technologies for generating hydrogen from wastewater through biodegradation of organic waste by exoelectrogenic microbes. In the MECs, the operational parameters, such as applied voltage (Eap), anode surface area, anode-cathode distance, and N2/CO2 volume ratio have a significant impact on the hydrogen yield and producti...

Because of the intermittent behavior renewable sources, efficient, reliable and clean energy storage technologies are needed to achieve a more stable secure supply. In this context, hydrogen play key role because they can store large amount for long time. study, hydrogen-based electrical system, integrated with solar power plant, is designed analyzed from perspective. The system consists photov...

Hydrogen is a clean and environmentally friendly energy vector that can play an important role in meeting the world’s future needs. Therefore, comprehensive study of potential for hydrogen production from solar could greatly facilitate transition to economy. Because by knowing exact amount production, cost-effectiveness its be compared with other methods production. Considering above, it seen s...

Bacteria able to generate electricity in microbial fuel cells (MFCs) are of great interest, but there are few strains capable of high power production in these systems. Here we report that the phototrophic purple nonsulfur bacterium Rhodopseudomonas palustris DX-1, isolated from an MFC, produced electricity at higher power densities (2720 +/- 60 mW/m2) than mixed cultures in the same device. Wh...

Whilst hydrogen is a potentially clean fuel for energy storage and utilisation technologies, its conversion to electricity comes at a high energetic cost. This demands the use of rare and expensive precious metal electrocatalysts. Electrochemical-frustrated Lewis pairs offer a metal-free, CO tolerant pathway to the electrocatalysis of hydrogen oxidation. They function by combining the hydrogen-...
