Florida, USA-based energy storage start-up Concept by US is due to start shipping its all-in-one battery systems to Africa in May.

For the African market, the company has created a 50Hz, 220V, three-phase version of its Powerstation 247 Plus integrated battery system. It will be installing the units in Africa on behalf of an un-named African energy firm.

Units will be going into African locations ranging from high-end resorts to small off-grid communities, said Sara Kissing, vice president and chief operating officer.

The Powerstation 247 Plus is a solar, wind and diesel genset-ready edition of what Concept by US claimed was the market’s first true integrated home storage system when it launched last year.

Concept by US expects to sell 800 units this year, split almost evenly between African and America. In the US, the company’s biggest markets are California, Texas and Florida.

Alevo, a Swiss battery maker with operations in Concord, North Carolina, USA, has confirmed the first commercial delivery of its sulphur-based lithium-ion GridBank product.

The company is due to install six 2MW/1MWh GridBank units this month across three sites in Hagerstown, Maryland, to provide frequency regulation and other ancillary services to the PJM Interconnection Market.

Speaking to Energy Storage Report during European Utility Week last year, Alevo officials confirmed that two other projects were already “grid connected.”

The implication is that these two projects, a 8MW/4MWh deployment Lewes, Delaware, which was announced in March 2016, and a 10MW, 3MWh project in Georgetown, Texas, are non-commercial pilots.

According to the Charlotte Business Journal: “The company has taken longer than initially expected to get to commercial production of the battery and its control systems.

Military interest in energy storage remains strong

Military enthusiasm for energy storage applications is at an all-time high, according to one supplier close to the industry.

“There’s no doubt that their interest is strong,” said Ryan O’Keefe, senior vice president of business development at the power conversion systems maker Ideal Power.

Energy storage is seen as one of a number of technologies that can help military chiefs offset costs and risks while allowing troops to operate more independently in the battlefield, he said.

“They identified quite some time ago that their military bases, wherever they are, are at the mercy of the electric grid. The military is clearly in planning mode for how to make their operations resilient.”

Ideal Power is currently working with “a couple” of military suppliers on how to improve frontline logistics and power quality.

Lithium-ion’s potential to dominate the stationary storage battery sector may be stronger than previously thought, according to the implications of a new study.

Research published last week by the analyst firm Bloomberg New Energy Finance (BNEF) shows a glut of second-hand lithium-ion (Li-ion) batteries from the auto industry could cut battery storage costs significantly.

By 2018, says Used EV batteries for stationary storage: second-life supply & costs, the cost of repurposing batteries for second-life applications could go down to as little as USD$49 per kWh.

This compares to a cost of roughly $300 per kWh for new batteries at the moment, and $160 for lowest-cost battery chemistries such as the zinc hybrid cathode technology being commercialised by Eos Energy Storage.

Given that BNEF expects around 10GWh of capacity from used electric vehicle batteries to be entering into the stationary storage market by 2025, second-life applications could deal a real blow to the prospects for non-Li-ion chemistries.

Encell’s hardy battery targets emerging markets

Battery start-up Encell Technology is taking aim on emerging markets with a residential-scale product that bucks the current trend for sleek, eye-catching design.

The company’s Fused Iron batteries are visually unimpressive but able to perform better and withstand a much wider range of operating conditions than lithium-ion (Li-ion) rivals, said Encell chairman and founder Robert Guyton.

“There are fundamental trade-offs in lithium-ion when it comes to cost, cycle life and safety,” he said. “It’s a zero-sum game.”

Evaluating the trade-offs led Encell to select a nickel-iron battery chemistry instead.

Nickel-iron batteries have low specific energy and poor charge retention but are popular in mining because of their long operating life, of up to 20 years with regular cycling, and their ability to withstand harsh environmental conditions.

One battery to rule them all?

The Tesla Powerwall launch three weeks ago focused attention on energy storage but may also have been a nail in the coffin for non-lithium-ion (Li-ion) technologies.

In drastically reducing prices, Tesla removed one of the remaining barriers to adoption of Li-ion as the standard for battery storage.

Currently other technologies are vying for supremacy on the basis of cost, safety, performance and bankability.

However, the launch of a residential battery system for USD$3,500 helped lay to rest the idea that Li-ion is automatically more expensive than other chemistries.

Even Tesla’s grid-scale Li-ion offering, the Powerpack, looks competitive with the most cost-effective battery technologies out there.

Tesla Gigafactory: nothing but good news for energy storage

As Reno wins the jackpot to be the location of the Tesla Gigafactory, we look at what it means for Tesla, Nevada and the energy storage industry.

The waiting is finally over. And surprise, surprise, Nevada, the state that never missed an opportunity to bend over backwards for big business (an attitude Bugsy Siegel may have appreciated), has scooped Tesla’s Gigafactory for a mere USD$1.25bn in subsidies over the next two decades.

Okay, let’s park the cynicism over the vast sums corporations squeeze out of the tax-payer and look at the positives of what will be a real game-changer in energy storage, not just for electric vehicles and their drivers, as well as providing a bit of background.
