Introduction Renewable energy offers a hopeful promise to reduce the energy sector’s carbon footprint, but many challenges must be addressed before it can be more extensively integrated into our society. One of the greatest barriers to widespread adoption is quite simply that due to the nature of renewable energy – the fact that it is produced only when solar rays, wind, etc. ...

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 ...

In this post we examine the economics of solar + storage. Specifically, we calculate the value of solar and storage for two commercial buildings in each of three markets: California, New York, and Hawaii. We find solar and storage are strongly synergistic in all three markets. The NPVs of solar + storage investments are greater than the sum of the NPVs of solar investments and storage investments ...

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 ...

Independent and affordable electricity supply for your home – until now that was not feasible from a technical perspective. But that’s exactly what the new SMA battery inverter Sunny Boy Storage offers. In March, the inverter has been honored with the Innovation Prize at the PV symposium Bad Staffelstein. Volker Wachenfeld, Executive Vice President of the SMA Offgrid ...

Researchers have provided a set of guidelines to help policymakers, designers and operators develop sustainable solutions for energy-storage systems for electricity grids. The guidelines cover a range of energy-storage technologies and grid-integration options. As societies move towards decarbonising the world’s energy supply and reducing greenhouse gas emissions, energy storage is ...

Claiming that we don’t want energy storage seems like a provocative thing to say. For example, the Energy Institute (EI)’s 2015 Energy Barometer report, a survey of professionals in the energy industry, rated storage as the area most in need of innovation. My point isn’t that energy storage isn’t ...

This research studies the behavior of a fully confined air pocket under the effect of water pulses induced by a water hammer phenomenon using several experimental tests in a pressurized transient condition. A compressed air vessel (CAV) has been tested under transient conditions to show its ability to absorb the pressure surges and to demonstrate the energy storage capability of the air ...

At least since the end of April, when Tesla introduced its Powerwall, everyone seems to be talking about the market for stationary battery-storage systems. At any rate, it was the dominant topic at Intersolar. I asked Volker Wachenfeld, an SMA expert in storage technology, about his assessment of the market and SMA’s plans for battery-storage systems going forward. - See more at: ...

Opportunity In 2011, AES Gener, in cooperation with its subsidiary Empresa Electrica Angamos, completed construction on a 544MW thermal power plant in the town of Mejillones in Northern Chile. The plant provides electricity to this important mining region. To ensure grid reliability against transmission or generation losses, power generators in the region each hold back capacity to meet ...

Major research efforts have been focused towards developing high dielectric constant ( ε ), low loss (tan δ ) and high electrical breakdown dielectrics for energy storage capacitors. Combining the low cost, ease of processing and high breakdown field strength (BDS) of polymers with the high ε ceramic fillers will result in high-energy storage capacitors. ...

Wind energy systems offer a promising alternative energy source due to the environmental, economic, and social benefits and, as a result, have garnered support for development and implementation. One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a ...

In the future smart grid, improvement of power system economic cost effectiveness by suitable integration of distributed energy resources (DERs) is a critical challenge. An agent–based framework is proposed in this paper for developing suitable control strategies for operations of four different types of residential–level DERs, which are storage devices, photo voltaic systems, and two ...

Abstract Electromagnetic radiation efficiency and radiating capability of impulse antenna are discussed at this paper. A term of impulse antenna is referred to an electromagnetic pulse radiation system with short pulse response. Relation between such antenna characteristics as storage factor, efficiency and radiating capability is considered here. Improvement methods of impulse antemia ...

Systems used to extract renewable energy often are subject to suboptimal working conditions due to the intermittent nature of most renewable energy sources. The flywheel energy storage system suggested in this paper utilises an electronic clutch that engages and disengages the generator from the flywheel of the renewable energy system in an attempt to prevent the generator rotor from coming to a ...
