  • 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 ...

  • How do Photovoltaic Cells Actually Work?

    Solar power is an abundant renewable source that could be the solution to our future energy needs, but just how does a solar array produce the electricity that powers our lives? The short answer is that, through a solar panel, photons (light particles) are able to knock electrons off atoms and this causes a flow of electricity. The long ...

  • 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 ...

  • Are fuel cells the future for stationary power?

    Fuel cells are one solution for generating stationary power for industry and grid balancing, but they are currently not competitive with conventional generation. Marc Height has a look at the market and at new, lower-cost technology coming to the fore that could change the playing field. Input hydrogen and oxygen into a very particular box and, like magic, electricity is produced, alongside heat ...

  • 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 ...

  • How will this new development in batteries make wind and solar power more completive?

    The trend is changing in obtaining energy from conventional sources to obtaining energy from solar and wind power units. The change in trend is due to this energy is considerably cheaper than the energy obtained from several other methods. Earlier an expensive metal was used over in the chargeable batteries for solar and wind units. Mostly these units contain platinum and other very expensive ...

  • 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 ...

  • New topology for management of bi-directional power flow between vehicle and grid with reduced ripple current at unity power factor

    In this paper, a new topology of single-phase pulse width modulated (PWM) AC-DC converter is proposed for bidirectional power flow between plug-in hybrid electric vehicle (PHEV) and the grid. This converter consists of a PWM voltage source converter (VSC) and a ripple reduction circuit. The ripple reduction circuit consists of a switching leg and an inductor. The inductor is connected between ...

  • 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, ...

  • A power-flow control method for hybrid active front-end converters

    The hybrid active front-end converter, which is composed of a capacitor and a voltage source converter in series connection, has been presented recently. Compared with grid-connected converter, the hybrid converter could be operated with reduced dc voltage as well as small-sized passive filters due to series-connected capacitor. This paper presents a power flow control method for a hybrid active ...
