Yep;

"Baseload isn't providing many technical details at this stage, but the key to its low cost is relying on sulfur. That's because the material is very abundant and energy-dense, Chiang says. Indeed, it's a waste product of oil and gas production that costs as little as 10 cents per kilogram.

"Based on the charge stored per dollar, sulfur was more than a factor of 10 better than the next best thing," says Chiang, a materials science professor who previously cofounded lithium-ion battery startups A123 Systems, 24M, and three other startups."

"Clark seemed, however, more bullish on the economics of energy storage, which he described as the “elephant in the room”. “We’ve hardly spoken about the subject and yet people who are able to deploy storage will make money,” he remarked. “Batteries will help stabilise prices and the big question for Italian PV owners is – do you own the battery or do you rely on the market?”"

"On Tuesday, the Los Angeles Department of Water and Power (LADWP) Board of Commission unanimously voted to purchase power from 8minute Solar Energy's Eland hybrid for a 25-year period, at record-breaking fixed tariffs for solar (US$0.01997/kWh) and energy storage (US$0.013/kWh)."
...
However, some in the solar ranks have questioned whether ultra-cheap Eland can remain money-making for 8minute. Writing for PV Tech in August, Gensol Group vice president Ali Imran Naqvi examined how the US$0.01997/kWh bid will play out economically based on assumptions over component choices, investment tax credit (ITC) support, energy yield and other factors.

“Plugging these numbers in our model threw an equity return of 5%, which leaves very little room for applying sensitivities for these important factors,” Imran Naqvi remarked. “We were filled with enthusiasm at the beginning of this effort to understand the mind of the bidders but burning the midnight oil does not yield much light, it appears.”

"While LNG or LNG-ready ships top this chart, coming in at second place are battery-assisted vessels, which are now being installed on almost every single segment of the global merchant fleet. Battery-powered ships include fully electric vessels, and chargeable and non-chargeable hybrids. The take-up has been strongest in the ferry sector followed by OSVs to date.

Commenting on the growth of battery use in shipping, Greg Atkinson from Japan’s Eco Marine Power commented: “The use of a variety of battery technologies is likely to become more widespread across shipping especially as some ship types move towards using electrical propulsion. We are also likely to see technologies specifically developed for land-based electric vehicles including solid-state batteries being adapted for ship use also.”"
