We use cyclic charge-discharge experiments to evaluate the capacity retention rates of two quinone-bromide flow batteries (QBFBs). These aqueous QBFBs use a negative electrolyte containing either anthraquinone-2,7-disulfonic acid (AQDS) or anthraquinone-2-sulfonic acid (AQS) dissolved in sulfuric acid, and a positive electrolyte containing bromine and hydrobromic acid. We find that the AQS cell...

the iranian ministry of energy commands the regional electrical companies to install dg resources at 63kv/20kv substations and at the end of 20kv lines. the first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. this paper is aimed to propose an appropriate algorithm for siting and sizing such resources in bakhtar regional el...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

producing biogas is the most common method of energy generation in municipal and industrial wastewater treatment plants in the world. methane production rate depends on degradation rate of organic pollutants in wastewater, temperature and treatment process. typical parameters for assessment of organic wastewater such as bod or cod indicate the potential to produce methane. there is no accurate ...
