Integrating Reverse-Electrodialysis Stacks with flow batteries for improved energy recovery from salinity gradients and energy storage
Abstract Salinity gradient energy can be directly converted into electrical power by using reverse electrodialysis (RED) and other technologies, but reported power densities have been too low for practical applications. Herein, the RED stack performance was improved by using 2,6-dihydroxyanthraquinone and ferrocyanide as redox couples. These electrolytes were then used in a flow battery to ...

Repurposing Methylene Blue in Flow Batteries
Methylene blue consists of a blue dye used in the textile industry. A new study, published in mid-August 2018, reveals that the dye can be repurposed for use in redox flow batteries. After establishing that the chemical compound has electrochemical properties, chemists at the University of Buffalo divulged that, as an active ingredient, it can be used to store energy. In the textile industry, ...

Highly-Standardize Batteries for Express Convenience
Batteries of any kind matters to the preservation of renewable energies. Hence, we are referring to the ways of preservation of renewable energies here, including solar and wind energy. In fact, the availability of solar and wind energy is passively argued in several times because solar energy is precisely presence in daylight. Yet, solar power systems can work overnight in a way that experts ...

Batteries Are the Heart of Renewable Energy
US researchers have made a vital step ahead in the pursuit to amass electricity from irregular energy resources like solar energy and wind energy. A Harvard University group has turned up with a technique to cut down the expenditure of flow battery technology that is competent of storing energy on big scales within an electrical power grid. Grid-scale storage for renewable resources could be a ...

Saving Renewable Energy for a Rainy Day
Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...

Interview with E. Caglan Kumbur, Ph.D., Asst. Professor, Electrochemical Energy Systems Lab, Department of Mechanical Engineering and Mechanics at Drexel University
Energy storage technologies have the potential to improve grid efficiency and reliability by optimizing power flows and supporting variable power supplies. However, storage applications are often costly and don’t always produce achievable returns in every grid scenario. Finding a reliable and profitable strategy within electric storage can be a daunting and confusing task, as utilities ...

Project - Development of the Balasausqandiq Deposit
The Balasausqandiq deposit is a very large black-shale deposit containing vanadium and valuable by-products - uranium, molybdenum, aluminium, rare earth metals and carbon. This deposit is unlike the vast majority of other vanadium deposits, either in production or proposed, in that it is not comprised of vanadiferous titano-magnetite and is amenable to a processing method which is much lower in ...

Ambri Is Still Alive and Chasing Its Liquid Metal Battery Dreams
Among the ranks of lithium-ion alternatives these days, simply staying alive counts as above average. Ambri, the liquid metal battery startup spun out of MIT materials research, has achieved that distinction with flying colors. After halting commercialization to address a technical problem with the seals on its high-temperature battery cells, the company started afresh with a new, lower-cost ...

A Heated Discussion on Lead-Acid Batteries
Having just endured one of the hottest Julys on record, many people have been subjected to extremely hot environments lately. And, in some cases, where their bodies have produced or absorbed more heat than they could dissipate, people have been experiencing an abnormally high body temperature due to the failure of their body to thermoregulate. This is called hyperthermia. In fact, as I wrote ...

Financial Analysis of Energy Storage - Case Study
Net present-value (NPV) is the current worth of a future sum of money or stream of cash flows given a specified rate of return. It is a great tool to analyse the profitability of an investment independent of different lifetimes and account for inflation and degradation – two of the biggest impacts on ...

There’s a new contender in the quest for the next superbattery
It’s been nearly 40 years since the battery world had a major shake up. In 1980, a researcher at England’s University of Oxford made the first breakthrough that would eventually take lithium-ion batteries from theoretical to possible. But the industry was slow to embrace the shiny new design. It would be more than a decade before Sony decided to throw its weight behind lithium ion, ...

Cathode Studies: New Opportunities in Li-Ion Batteries
Research and development (R&D) into novel energy storage materials is important to improve the utility of energy generated from renewable sources, thereby reducing reliance on fossil fuels, a finite resource. Lithium ion batteries are a central to such initiatives, and are increasingly pivotal in green markets like that of hybrid electric vehicles (HEVs). Fossil fuels are a finite resource ...

Battery Management for Large-Scale Energy Storage (Part 1)
Battery Management and Large-Scale Energy Storage While all battery management systems (BMS) share certain roles and responsibilities in an energy storage system (ESS), they do not all include the same features and functions that a BMS can contribute to the operation of an ESS. This article will explore the general roles and responsibilities of all battery management systems, and will also ...

The Path to a Vehicle-to-Grid Future
Is a vehicle-to-grid future possible, where bidirectional chargers allow electricity to flow from electric vehicles back to the grid during peak demand? Given the current state of electric vehicle (EV) technology, coupled with existing pilot projects, we believe it’s more suitable to ask: what useful vehicle-to-grid applications can we implement today, and what valuable benefits await to be ...
