I think grid-scale alternative energy management is one of the most interesting--and to judge by some of the comments on this site, least understood--of alternative energy subjects. It's not just about storage, but about deploying what's needed where at the right time, quite a delicate balancing act. The system operators in California and Texas, where there's a lot of solar and wind power on the grid, have been doing this successfully for some time.

right now, to meet Grid contracts,  a wind farm bids in Megawatt hours to the grid on the spot market.  

 

According to a buddy of mine the worst thing to ever deliver is the Megawatt-59minute.

he goes, you deliver a lot of power and pay for the privelige of doing so.

so say you have 10 1 megwatt turbines and the wind is really strong and predicted strong, you will likely bid 9 MW-H to the grid, because, you want some reserves.

if the wind is weak and variable you may bid 3 or even 2 MW-H, hoping that part of your array will be catching wind.

 

so adding some decent battery say 15 minutes of drop out protection, means that

in scenario 1 you may bid 10 MW-H and in scenario 2 you may bid 5 MW-H,

that's what i mean by increasing revenue.

 

as to reducing workload, when you blow your supply contract the Grid operators

may start up a bunch of gas turbines fast to deal with a frequency problem or voltage sag or start importing power, and that's workload to the grid managers.

if wind farms become rock solid producers, they reduce work to the grid managers

Thanks for that link, Ann. It definitely provides perspective on the concerns about overall management and system maintenance that grid-scale storage requires in quite plain terms. So not only do the batteries themselves have to meet the right price point and storage capacity, along with the usual requirements of energy storage, but they also have to fit well into the overall grid structure.

Yes, Chuck, I think cost is the key. We'll see how these storage efforts pan out--hopefully one of them can hit the affordability sweet spot.

Thanks for your comment, patb2009. Yes, they are definitely viable; what I meant was that storage will allow them to play a larger role in grid operations than they currently do. I'm not sure what you mean by "increasing revenue and reducing workload"? Can you clarify that point?

"As renewable energy sources like wind and solar become more widely used, the next step is to find a way to make them a viable part of the electricity grid."

 

i would say PV and wind are viable to the grid because they are used on the grid,

the issue is increasing revenue and reducing workload to grid operators.

High energy density and cheap, easily-available materials are a great combination. For renewable energy storage to work, cost-effectiveness is going to be a must.

Here's an interesting article discussing grid-scale batteries and their management (via a specialized OS), equally important as battery design when it comes to optimizing output via load-shifting and other techniques: http://www.greentechmedia.com/articles/read/designing-grid-batteries-to-live-long-and-prosper

As another discussion point, here is information on another one of those efforts to create a viable storage battery: http://www.designnews.com/document.asp?doc_id=255495

This is yet another promising advancement in this busy area of research. If there is viable storage then renewables, which already are becoming more widely used and really are the way forward to reduce or even eliminate independence on the traditional electricity grid, can play even a larger role in providing power to millions if not billions of people. I know of a couple of other efforts in this area--the MIT-spawned Ambri comes to mind: http://www.designnews.com/author.asp?section_id=1386&doc_id=259497--but does anyone know of any good ones as well to add to the discussion?

With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Enterprising Tesla Model S owner Steve Sasman seems to have figured out a way of recouping some of the cost on his car by renting the trunk out on AirBnB, the room/house rental website.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
