This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

"Most recently, they've been piloting distributed energy storage (DES). If the predictions below are true, DES could be a real game-changer."

Although volatility in most assets is sharply lower than it was in November, oil price volatility has continued to climb. This rise in volatility, and resulting near $30-a-barrel oil price, is reflecting the same imbalances in the energy market that $147 oil did last summer: namely inadequate investment in basic infrastructure to produce, deliver, store and distribute energy. Last summer, attention focused on shortages in production capacity. However, present underlying shortages in storage and transportation are creating massive price distortions across the energy complex. Storage and transportation capacity provides the system with a buffer to supply-and-demand shocks by allowing it to run surpluses and deficits that smooth the normal cyclical swings in prices. As global storage capacity has failed to keep pace with growth in global demand over the past three decades, this buffer has shrunk relative to the size of the market, resulting in chronically higher than normal price volatility. Once infrastructure begins to constrain the ability of the market to run imbalances, prices have to create more of the adjustment process. Electricity markets are an extreme case of this. As power cannot be stored, supply must always equal demand, leaving price as the only mechanism to force the adjustment process. Accordingly, electricity is the most volatile of all assets. Due to inadequate infrastructure investment over the past several decades, oil is looking more like the electricity markets.

In fact, many researchers believe energy storage will have to take an entirely new chemistry and new physical form, beyond the lithium-ion batteries that over the last decade have shoved aside competing technologies in consumer electronics, electric vehicles, and grid-scale storage systems.

However engineers and scientists at The University of Texas at Austin have made a breakthrough in the development of a new carbon-based material that they believe might allow for at least a doubling of current electricity storage capabilities. The new structure is called grapheme, and measures in at one atom thick

"The supporting technologies associated with energy storage systems include power conversion (primarily focused on inverters), system-level software and controls, and systems integration services. "

"Lithium-ion battery life and their limited warranties have been one of the limiting factors for the widespread adoption of energy storage"
