Toshiba Corporation has announced that it has delivered two battery energy storage systems to Kyushu Electric Power Co., Inc. in Japan. Both units are for a demonstration project to make renewable energy more practical.

“The systems have been installed in substations on Tanegashima Island and Amamioshima Island, in Kagoshima prefecture, and will be used to demonstrate the integration and optimum control of battery energy storage systems deployed to manage frequency regulation and maintain stable power supply on remote islands, which are increasingly turning to renewable energy sources. The demonstration program will run for three years to fiscal 2016.”

“When large-scale renewable energy sources such as wind and photovoltaic are integrated into power grids on remote islands, power frequencies tends to fluctuate due to intermittent power outputs from the renewables. Toshiba’s battery energy storage systems provide such islands with an excellent solution for efficient and effective frequency regulation.”

The Japanese company is using in energy storage applications its SCiB lithium-ion batteries, which are known from high durability (over 10,000 charge-discharge cycles) and quick charging capability (to 80% in 6 minutes).

The same type of battery is used in Honda Fit EVs and in some versions of Mitsubishi i-MiEVs in Japan, as well as in some prototype vehicles.

The latest energy storage systems installed by Toshiba have 3,000 kW of power and 1,161 kWh of energy in Tanegashima Island (equivalent to 60 Fit EV packs) and 2,000 kW and 774 kWh in Amamioshima Island (equivalent to 40 Fit EV packs).

Toshiba is building such storage systems in other places in Japan and around the world (including Europe). One of the orders is for a 40 MW system, which is 10-fold larger than previously described.

“Toshiba is promoting battery energy storage system globally as a support for stable power supply, and is involved in Smart Community projects around the world. In Japan, these include a renewable power supply project in Okinawa and a large-scale urban project serving homes and offices in Yokohama. Overseas, they include a collaborative on-site verification testing program with GAS NATURAL FENOSA, one of Spain’s leading natural gas utilities, that uses a transportable battery energy storage system to achieve an efficient, reliable and stable distribution network*. In commercial systems, Toshiba has received an order for the battery energy storage system from Rome-based ACEA Distribuzione S.p.A (Gruppo ACEA), one Italy’s leading public utilities, and in Japan an order from Tohoku Electric Power Co., Inc. for a battery energy storage system with the output of 40MW, the world’s highest class.”

Granted it doesn’t matter much for stationary applications, but what’s the SCiB’s energy density?

I’d be interested in cost per kwh…

If I were the coal Industry I would be very worried about this in that we are entering the phase of solar power were there are already massive solar projects already built. And now they can enter the energy storage phase were they can build big battery farms next to existing solar farms vs having to build the solar farm from nothing.

The coal biz is pretty dead these days in the USA due to solar PV, wind, and (mostly) natural gas. And that is GOOD. We don’t need any new coal plants at this point. We can do fine with solar PV, hydropower, wind, solar thermal, geothermal, natural gas, nukes, and other sources.

INCORRECT! The ‘coal biz’ is doing just fine, its just that it is uneconomic to use it here because of all the carbon taxes. All the coal essentially that was used here is either shipped to China, or the “thermal coal” is shipped to Europe to compete with the high price of natural gas. It matters not what “green Europeans” say, it matters more what they do. Of course, CO2, a building block of life, is not a problem at all, as the many experts I’ve quoted in the past can attest to. But as long as people believe it is, then whatever. I don’t blame people 30ish and under since they’ve had plenty of fictions drumed into their heads since kindergaten, but older people should know better. The current NPR reporting on the Ukraine would make Joseph Goebells blush, but that’s another subject. Anyways, arrow slingers here will be glad that I’m finally taking the plunge into a quite large solar panel array, and it is nothing to do with ‘saving the earth’ or polar bears, who are at record populations these days. Has much more to do with an 80% Increase of my February electric rate; as a… Read more »

“its just that it is uneconomic to use it here because of all the carbon taxes.”
Meaning it is only economical if they have to pay for the damage they cause.

“Of course, CO2, a building block of life, is not a problem at all”
So is oxygen, but try breathing in an 80% oxygen atmosphere as see how that works out for you.

“…but older people should know better.”
I am one of the ‘older people’ and do know better; you seem not to.

“…Has much more to do with an 80% Increase of my February electric rate”
Yes, people seem only to care about their wallets, to hell with the rest.

80% oxygen level is just fine actually, but 80% CO2 would be problematic.

My favorite is Hydreliox though, that is a mixture of Hydrogen, Helium and Oxygen that allow you to breathe under 45 atmospheres of pressure. The super nice thing about it is that it is the pressure that is present on top of the Maxwell Mounts on Venus (an area about the size of Texas). So you can walk there breathing that special gas in a non pressurized suit. Of course that doesn’t prevent you from having an U-vacua type insulation system and a CO2 boil off gas cooling system. Nevertheless you would be ok for a one hour free walk on the ground. Afterwards you come back to a base that has to be actively cooled to support the 380°C that still is present at the 11 km altitude of the Maxwell Mounts. The best for that would be thermo acoustics because it is only relying on a longer stack length for higher temperature difference. The good thing on Venus is that you don’t need to worry about cosmic radiation since you have such a thick atmospheric protection. Of course breathing Hydreliox all the time will change your voice tone somewhat. Sorry totally out of topic although not completely since… Read more »

Seeing as CO2 concentration is only 0.039% currently, this leaves a bit of headroom until getting to 80%.

It is, or used to be, considered a ‘trace’ gas. Quite amazing that plants can suck such a faint amount of valueable food out of the air.

No further comment from me until critics read all my prior posts.

For critics to do any less shows a great lack of scholarship.

Forget the fossil gas though, we don’t need it neighter.

Yeah, unless Japan restarts their nukes, they need to install tons more solar PV, wind turbines, and some storage.

If I were in control there, I’d definitely restart some nukes and install tons of renewable energy.

Plenty of people in Fukushima prefecture are glad you’re not in control.

Ahem, but with only 2 of 52 reactors running, there is a lack of 50 hz in Japan. There’s sufficient 60 hz but they lack sufficient cycloconverter capacity at the ties, and the DC ties can’t make up enough of the shortfall either.

Energy storage for peak use during the day just makes sense, since in this quite exceptional situation, the cost of peak hour demand electricity is extremely high. Huge battery supply facilities while expensive are cost effective for the job.

It is somewhat Ironic that the next 2 reactors (1660 MW Net) are the Sendai units and therefore 60 hz.

@ dr. Kenneth,
Can’t remember the source but I think the Toshiba SciB energy density is between 60wh/kg and 70wh/kg. Its lower than LiFePo which is between 80 and 100wh/kg, but is the most power dense. I.e faster charge and discharge cycles.
