Researchers Develop Another Potential Battery for Renewable Energy Storage
Yi Cui, an associate professor in the Department of Materials Science and Engineering at Stanford University, holds a lab demonstration of his research group's new lithium-polysulfide flow battery contained in a simple flask. The design could serve as a model for a low-cost, long-life battery that enables solar and wind energy to become major suppliers to the electrical grid. (Source: Stanford University)
I think you're right, Ann, I think this area deserves more coverage and exploration. I think there is a good story to be had in how it's been managed in those states and how others might learn from this example. Do you know how if they use storage devices in those states and how they do it? It would be really interesting to delve into more. I've done a few stories now and didn't know they were managing it so well in those regions.
The biggest problem is the fluctuations, with renewables more than 20% a large cloud could make such a dent in the power provided the grid that a few turbines would have to spun up and then down as thcloud passes, the only problem is that large turbines take perhaps a minute to go from 0-100% (someone please feel free to add a real number here, this one's out of my hat - gut feeling) where as currently they only need to go upi or down 10% which is much shorter.
"which already are becoming more widely used and really are the way forward to reduce or even eliminate independence on the traditional electricity grid,"
Small typo above?
Thanks for posting this, It's good to see that electrical storage research is alive and well.
We have a 4kW systems and it just about covers our usage in spring an autumn an definitely in Summer but winter is another story. On a sunny day it's only supply positive for 4-7 in shoulder periods so effective storage would be a real boon.
I can imagine that if we had more than 20% solar or wind that dotty cloud cover or buffeting wind would be a real drama without storage.
I Europe there's talk of using EV's plugged into the grid as a levelling sytem for renewables. The interesting thing here would be that the grid would be reducing the life of the EV battery through extra usage and may have offer storage credit much the same way that feed in tarifs work :-)
Really, Chuck? That's pretty high profile to be on The Colbert Report. That is definitely interesting, and quite cool that he would apepar there--shows a bit of progressiveness on the part of Colbert and some savvy marketing on the part of Sadoway. I haven't checked on their progress in awhile so I wonder how much traction Ambri is gaining--possibly quite a bit.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
