New Battery Could Enable Cheaper Energy Storage

New Battery Could Enable Cheaper Energy Storage

A new type of rechargeable flow battery engineered by MIT researchers, which doesn’t require costly membranes in order to store and generate electricity, may prove to be a key component in developing cost-effective large scale energy storage. The lack of affordable and efficient methods for storing both solar and wind energy during peak generation times, in order to later release it during periods of high demand, has often been touted as one of the stumbling blocks to further renewable energy penetration. But if the new rechargeable flow battery developed at MIT can be further refined and scaled up, it could… read more

ReadySet Solar Kit Funds Power for All


The Fenix ReadySet solar kit is not only a great choice for off-grid power in the developing world, but because of our digital lifestyle, can be the perfect addition for meeting our emergency and outdoor power needs. The ReadySet charges with a solar panel (or other input, including house current), and then stores and provides enough energy to power lighting, charge cellphones, or even run an iPad for over 12 hours. Originally designed for the demanding environment of Africa, the robust 54 watt-hour system is built to stand up to being used every day, and can serve as a renewable… read more

3D Printed Batteries as Small as a Grain of Sand

3D Printed Batteries as Small as a Grain of Sand

In the quest for smaller and smaller devices, some of our technology has kept pace, while others, such as tiny batteries for mobile devices, have not. But a recent breakthrough of a microbattery the size of a grain of sand hints at the next generation of tiny energy storage devices. A team of researchers have successfully built a tiny lithium-ion microbattery by using a 3D-printer to precisely print interlaced stacks of electrodes that are thinner than a human hair. The team, based at Harvard University and University of Illinois at Urbana-Champaign, first developed specialized inks that are both electrochemically active… read more

New Solar Cell Design Generates and Stores Energy

LA Launches Largest Rooftop Solar Tariff Program in U.S.

Solar PV panels are great at generating clean, renewable electricity from the sun’s rays, but one major drawback for them is that without an additional system to store that energy and release it on demand, they are only as useful as the reliability of the grid they are connected to. But a breakthrough at the University of Wisconsin may begin to change the way we design and implement solar panels, with a new solar cell design that can not only generate electricity, but can also store it for later use. The new technology is an offshoot of a project working… read more

Solid Lithium-Sulfur Battery Offers 4X the Energy Density of Li-Ion

Solid Lithium-Sulfur Battery Offers 4X the Energy Density of Li-Ion

A new type of battery that has four times the energy density of current lithium-ion batteries, yet uses a low-cost material, has been developed and tested at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL). The development of this new all-solid lithium-sulfur battery could lead to lower costs for energy storage, safer batteries, and increased energy density, and may lead to a sea change in mobile power for everything from portable gadgets to electric vehicles. Previous approaches to lithium-sulfur batteries were plagued by their use of a liquid electrolyte in the design, which caused premature failure in the… read more

Large-Scale Electricity Storage Could Come from Offshore Pumped Hydroelectric Plants


Efficient grid-scale storage and energy conversion solutions are key components to a smarter and more robust grid, especially with more renewable energy sources entering the market. Almost all (99%) large-scale electricity energy storage in the world uses pumped hydro technology, and a recent design for offshore energy storage from MIT takes that model and puts it at the bottom of the ocean. And now it looks like there’s another contender for energy storage solutions exploiting the pressure differential at the seabed, this time from Subhydro in Norway. “Imagine opening a hatch in a submarine under water. The water will flow… read more

High School Student Creates Tiny Supercapacitor for Rapid Device Charging

Eesha Khare

One day, your mobile phone could recharge in as little as 20 seconds, thanks to the work of a very talented high school student. We’re all tired of having dead batteries in our mobile devices that take hours to fully charge again, so innovations in small-scale energy storage could radically change the way we build, use, and charge our gadgets. 18 year old Eesha Khare, of Saratoga, California, may hold one of the keys to doing so, and now, thanks to the Intel Foundation, she’s $50,000 closer to bringing her invention to the market. Khare has developed a tiny supercapacitor… read more

New GE Wind Turbine Integrates Battery Storage

GE 2-5 120 wind turbine

One of the challenges for wind farm operators and power producers is taking the fluctuating nature of the wind and turning into a smooth and predictable flow of electricity, and a new wind turbine that integrates short-term battery storage into the system aims to help overcome that challenge. The new wind turbine package from GE, the 2.5-120, uses the company’s Durathon Battery technology, along with three software applications, as an “intelligent system” that can enable better decision-making and allow for more predictable short-term power production. According to GE, this system is the “first wind turbine to incorporate short-term battery storage… read more

Battery Breakthrough Could Benefit Solar and Wind Power


In order to further integrate solar and wind power into the grid, one of the things that can make a big difference is finding an economical way to store and release energy, and a recent breakthrough in battery design from SLAC National Accelerator Laboratory and Stanford University may be able to that. Because of the power fluctuations that are a natural part of solar and wind power installations, an energy storage system must be in place in order to smooth out peaks and valleys in the power supply by storing excess energy when it is generated, and discharging it when… read more

New 3D Microbattery Could Revolutionize Mobile Power


A team of researchers at the University of Illinois claims that by using 3D electrodes in “microbatteries”, battery units can be built that can be recharged 1000 times faster, and are much smaller but just as powerful. “The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.” – University of Illinois The new microbatteries has a so-called 3D structure, with “three-dimensional… read more
