Green Energy Hydrogen Battery by LAVO™ Australia. Redox-Flow Cell Stores Renewable Energy as Hydrogen. When it comes to renewables, the big question is: How do we store all that energy for use later on?
Because such energy is intermittent in nature, storing it when there is a surplus is key to ensuring a continuous supply—for rainy days (literally), at night, or when the wind doesn’t blow. Using today’s lithium-ion batteries for long-term grid storage isn’t feasible for a number of reasons. For example, they have fixed charge capacities and don’t hold charge well over extended periods of time. The solution, some propose, is to store energy chemically—in the form of hydrogen fuel—rather than electrically. This involves using devices called electrolyzers that make use of renewable energy to split water into hydrogen and oxygen gas.
“Hydrogen is a very good carrier for this type of work,” says Wei Wang, who is the chief scientist for stationary energy storage research at the Pacific Northwest National Laboratory in Washington. But water electrolyzers are expensive. Liquid storage of solar energy – more effective than ever before. Researchers at Chalmers University of Technology in Sweden have demonstrated efficient solar energy storage in a chemical liquid.
The stored energy can be transported and then released as heat whenever needed. The research is now presented on the cover of the scientific journal Energy & Environmental Science. Many consider the sun the energy source of the future. New hybrid device can both capture and store solar energy. Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation and desalination.
Unlike solar panels and solar cells, which rely on photovoltaic technology for the direct generation of electricity, the hybrid device captures heat from the sun and stores it as thermal energy. It addresses some of the issues that have stalled wider-scale adoption of solar power, suggesting an avenue for using solar energy around-the-clock, despite limited sunlight hours, cloudy days and other constraints. The work, described in a paper published Wednesday in Joule, combines molecular energy storage and latent heat storage to produce an integrated harvesting and storage device for potential 24/7 operation. The researchers report a harvesting efficiency of 73% at small-scale operation and as high as 90% at large-scale operation. T.

This Battery Can Power Electric Cars 1,500 Miles Non-Stop. A powerful new battery could give us electric planes that don’t pollute. Brightly colored molecular models line two walls of Yet-Ming Chiang’s office at MIT.
Chiang, a materials science professor and serial battery entrepreneur, has spent much of his career studying how slightly different arrangements of those sticks and spheres add up to radically different outcomes in energy storage. But he and his colleague, Venkat Viswanathan, are taking a different approach to reach their next goal, altering not the composition of the batteries but the alignment of the compounds within them. By applying magnetic forces to straighten the tortuous path that lithium ions navigate through the electrodes, the scientists believe, they could significantly boost the rate at which the device discharges electricity.
That shot of power could open up a use that has long eluded batteries: meeting the huge demands of a passenger aircraft at liftoff. The $2.5 trillion reason we can’t rely on batteries to clean up the grid. A pair of 500-foot smokestacks rise from a natural-gas power plant on the harbor of Moss Landing, California, casting an industrial pall over the pretty seaside town.
If state regulators sign off, however, it could be the site of the world’s largest lithium-ion battery project by late 2020, helping to balance fluctuating wind and solar energy on the California grid. The 300-megawatt facility is one of four giant lithium-ion storage projects that Pacific Gas and Electric, California’s largest utility, asked the California Public Utilities Commission to approve in late June. Collectively, they would add enough storage capacity to the grid to supply about 2,700 homes for a month (or to store about .0009 percent of the electricity the state uses each year).
But there’s a problem with this rosy scenario. These batteries are far too expensive and don’t last nearly long enough, limiting the role they can play on the grid, experts say. Small doses And that ends up being astronomically expensive.
