Storage Boosts the Power of Renewable Energy

Electricity Storage Association's Annual Meeting in California

VRB vanadium flow battery technology is already smoothing wind turbine output for remote power hybrid wind-diesel applications in northern Canada and Alaska and providing frequency regulation, voltage support and blackstart capability.

With over 200 megawatts (MW) of NaS batteries installed worldwide, Japan-based NGK Insulators, Ltd is another battery storage company hoping to capitalize on that rapidly growing market. The company's NaS batteries, used mainly for load leveling, enable companies to sell cheap off-peak wind power during peak times, thereby fetching a higher price.

technological applications such as the sophisticated vanadium flow batteries of VRB Power and the NaS systems of NGK combined with a variety of other storage options such as pumped hydro and compressed air systems demonstrate that the intermittency concerns often associated with renewables like wind and solar are quickly becoming manageable issues.

Actually, it was you who first claimed that there was electrical energy storage in post #266.
Your claim is simply incorrect.
Yet, you have made not a single point that in any way that supports your claim. Or indeed, refutes my statement. Not one.
Is it still can but won't? If so, why?

Well, that's rather what I was getting at. The dam doesn't store electrical energy. It is stored as a mass at a height - potential energy. It has to go through two stages of conversion before it is converted into electrical energy.
First through a turbine that converts it into mechanical witch then drives an alternator wich then converts into electrical.
If electrical energy storage was possible, there would be at least the possibility of greatly simplifying the conversion process.

Your were the first one in this thread, who claimed in several posts, that there was not electrical energy storage. Your claim is simply incorrect. Yet, you have made not a single point that in any way that supports your claim. Or indeed, refutes my statement. Not one.

Indeed. I suspect we all know what you were are getting at and why. It is possible to store electrical energy ( capacitors, batteries etc.. ) and this is discussed widely, but the initial discussion was in a broad context and was intended as such to include all methods direct and indirect via implicit conversion. Your arguments serve as a less than constructive distraction from the main discussion, just to try to make a point that in any event is wrong and misses the point of the discussion and does not enhance the quality of the discussion.

Ok, it's true that the dam doesn't store electrical energy but maybe that's being a bit precise. it's not like we're going to turn that water into wine, or make trees out of it. It's stored there for one purpose, and that's to convert it into electrical energy.

Energy derived, and being used, from solar technologies replaces the need for using hydro power until the sun goes down and so stored water is equivalent to stored electricity.

what, you'ld suggest we turn it into bitters?

What makes people think that hydro electric plants don't emit greenhouse gases?

It's a dead ball now. A range of storage technologies have been discussed some direct electrical, others indirect converted energy. Each to their own opinion. It's not worth allowing that aspect get in the way of more constructive discussion about the core issue of energy storage technologies. Otherwise we will just be going around in circles, wasting each others time.
