Energy Storage Breakthrough: Large And Powerful Redox Flow Battery Developed
March 19, 2013Nathan

A breakthrough has been made in the field of renewable energy battery storage. Researchers have developed a redox flow battery that reaches a stack power of up to 25 kW. This breakthrough in battery technology is important because it will allow the energy from intermittent sources of power, such as most renewables, to be more efficiently stored for later use. The new redox batteries are eight times larger than the systems currently in use, which are only capable of generating 2.3 kW of electricity, so it’s a significant increase in capability.

With Germany’s stated goal of being powered 100% by renewable energy by 2050, big improvements in energy storage would be very helpful, offering a means to balance out periodic fluctuations in the energy supplied by wind and solar. With this in mind, researchers from Fraunhofer-Gesellschaft set out to dramatically increase the size and capacity of the redox flow batteries that are currently commercially available, and they succeeded. The new battery is a significant improvement, capable of providing up to 25 kW of electricity. The prototype currently has an efficiency of up to 80%, and “can take a load of up to 500 amps of current.”

The improvements leading the battery were possible primarily as a result of “testing new membrane materials and researching battery management and battery design,” the researchers add. “Flow simulations helped them to optimize the cell structure. A complete redesign of the battery followed which enabled the Fraunhofer team to make their breakthrough.”
The next objective for the researchers is the development of a battery with a capacity of 100 kW.

Thank you for the exciting news! Now if they could just make all of the alternative energy products affordable for the average household, we could really reduce our carbon footprint. In addition, I must say that this country was the leader in the research and development of new technology, and frankly with the austerity measures that have been enacted in Germany, I'm surprised to hear that the scientists there have the funding to accomplish this feat.

Thnks, we need to resolve the storage issue to make renewables useful.

I installed storage here at our farm for solar electric in 2001. It's a 4 battery systems that works just fine and much better than a gas generator. I don't have to run to the gas station with a 5 gallon container for gas. It just goes on without my need to do anything and pulled me through hurricane Sandy. I had power. In fact, I didn't even know there was a power outage. Some people in New Jersey are still without power !

Your situation is awesome Alice! Some of my family members are struggling with power. My cousin may have to settle for a buyout. She's between the ocean and bay and is heartbroken. Lucky she and her son have family to stay with.

The role of this type of battery is amazing! Hope we all jump on board. Competition isn't a bad thing in this regard!

My cousin lives at the shore and had to redo her entire 1st floor. They were not in a flood zone. My other cousins home had a boat go through it in Atlantic Highlands. She is now homeless. Many people in my family live along the coast and have had lots of damage. My Aunt lost 3 cars. Yikes !

PermaCity First to Join Program Aiming to Accelerate Solar PV Projects

Panasonic Eco Solutions North America (Panasonic) and Coronal Management, LLC (Coronal) have announced that PermaCity Solar, located in Los Angeles, is the first charter member to join a new solar power project Alliance Program launched by the two companies.

PermaCity is a full-service solar energy company that works with customers to provide customized solutions from development and design to construction to ongoing maintenance and monitoring for solar systems. By joining the Alliance Program, PermaCity and future program members will have access to an integrated platform that aims to accelerate the sales and implementation process for solar PV systems.

"Panasonic and Coronal provide the first comprehensive end-to-end solution for solar photovoltaic (PV) projects between 250 kW and 20 MW to the underserved commercial, industrial, municipal and small utility scale markets," said Jamie Evans, Managing Director of Panasonic's U.S. solar platform.

"Our new Alliance Program supports developers and EPC providers with a stable project implementation and financing platform in conjunction with Panasonic and Coronal."

The Alliance Program offers benefits to participating members. Program members will enjoy additional credibility, reliability as well as marketing and brand resources as part of the Panasonic/Coronal platform.

Also included is a financing platform to eliminate the time and frustration of searching for multiple sources of capital. Panasonic and Coronal provide a proven model for projects, streamlining the process to reduce inefficiency, eliminate redundancy and provide more velocity to project development and implementation.

"The Alliance Program provides a perfect vehicle for expanding our business and offers our customers a superior solution that will deliver benefits for decades to come," said Jonathan Port, PermaCity's CEO.

"Finding financing for projects has been challenging. Having our projects developed, built, financed and maintained by a global brand leader of Panasonic's reputation with their partner, Coronal Management, is a true game changer."

WOW--this is great news---especially your news, Alice, that you had power despite the outages, and your sotarage was bought in 2001!!
