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.

Systems integrator Powin Energy could gain an award today for a seemingly bizarre energy storage application: using batteries to charge batteries.

The Oregon, USA-based company is among those shortlisted for a 2016 Energy Storage North America Innovation Award for an electric vehicle fast-charging station at the headquarters of microprocessor firm Intel.

The installation, in Santa Clara, California, uses Powin Energy’s Battery Pack Operating System (bp-OS) to manage 30kw and 43kWh of lithium iron phosphate storage linked to 15 SolarWorld PV panels with a capacity of 4.1kW.

The use of batteries for electric vehicle fast charging avoids the need for standard three-phase 208/277/480V AC connections and helps avoid high demand charges, said EV4, the firm that designed and manages the station.

The technology also makes it possible to place charging stations in areas where three-phase AC is hard or costly to obtain.

An executive appointment last month has signalled increasing confidence in the ability of flow batteries to tap into the promising market for long-duration energy storage.

Michael R Niggli, the former president and chief operating officer of San Diego Gas & Electric (SDG&E), joined the board of all-iron flow battery maker ESS Inc. amid a growing focus on storage applications exceeding four hours of duration.

“As the renewable energy trend continues to reach penetration levels of 25% to 35% and potentially well beyond, it’s evident that the impact on local distribution networks, and the entire grid, is going to be pretty profound,” Niggli told Energy Storage Report.

“That suggests there is a growing need for need for medium and long-duration storage.”

Electrical energy storage’s current focus on short-duration applications, such as frequency response, is partly a consequence of the still relatively low penetration of renewables in most grids and a need for ancillary services.

Why analogue utility rates in a digital world?

They say anything can happen in a New York minute. Could one of these minutes change the way we look at demand management, though? After all, from an energy standpoint, not all New York minutes are the same.

Depending on the time of day, electricity in New York can vary significantly in price.

It’s hardly surprising: at certain times, Consolidated Edison (Con Ed), the utility serving New York City, has massive energy needs, peaking at around 13GW. That’s nearly a third of typical peak demand in the entire state of California.

At the same time, base-load production capacity is threatened by the possible closure of the Indian Point Energy Center nuclear plant.

New York Governor Andrew Cuomo’s laudable aim is to replace nuclear fission at Indian Point with nuclear fusion… from the sun. Cuomo is putting USD$1bn into installing 3GW of solar power across New York State by 2022.

Advanced Microgrid Solutions (AMS) of San Francisco, USA, is readying for a new fundraising round that could kick off as early as this month.

The much-hyped project developer is looking to bring in more than the USD$18m it achieved in its last financing effort, which closed just under a year ago.

“We are about to launch our series B and that will be concluded this year,” chief commercial officer Katherine Ryzhaya told Energy Storage Report.

The money will be used to speed up the growth of the company, which currently has 2.5MWh of storage in operation and aims to have installed more than 5MW and 3.5MWh by the end of this year, according to Ryzhaya.

“With the series B we will only be scratching the surface of the opportunity within the US,” she said. “We also have customers with a focus on the UK and Japan.”

Demand Energy last week announced completion of the first five energy storage projects in New York’s Demand Management Program (DMP).

One of the five 100kW, 400kWh behind-the-meter energy storage systems installed in five separate Glenwood properties across Manhattan has already passed measurement and verification (M&V) testing.

M&V certification is currently underway with the other four projects within the DMP, which is managed by utility Consolidated Edison (Con Ed) along with the New York State Energy Research and Development Authority (NYSERDA).

The aggregated behind-the-meter systems, with batteries from EnerSys, are powered by storage system developer Demand Energy’s Distributed Energy Network Optimization System (DEN.OS).

“We have been working during the off-peak season to install and interconnect the next four systems which make up the first 2MWh of installations for Glenwood,” said Shane Johnson, vice president of client services.

Highview Power Storage has launched a growth capital fundraising round amid commissioning for its first pre-commercial liquid air energy storage plant.

The 20-strong UK company is looking for an unspecified amount of cash but will most likely not be talking to venture capital (VC) investors, head of business development Matthew Barnett told Energy Storage Report.

“Rather than going down the VC route, we’re sticking with high-net-worth angel investors and strategic investors,” he said.

The latter group might include businesses that could add value to Highview’s offering, such as an engineering capability, a route to market or complementary technology, said Barnett.

“If a VC came up with GBP£15m then that’s a different story, but there’s a time and a place for a VC to be involved,” he continued. “Maybe we’re entering that now, maybe we’re not.

Oil giants pile into energy storage

By Jason Deign

The last week has seen two Big Oil firms move into energy storage as continuing low prices for crude force petroleum sector players to diversify.

On Monday the French oil giant Total announced a friendly takeover of Saft Groupe, which specialises in batteries for the transport, industry and defence sectors.

The €950m purchase represents a 38.3% premium on Saft’s share price on the close of business the Friday before the announcement. It is also 41.9% above Saft’s weighted average share price over the previous six months, Total said.

“The acquisition of Saft is part of Total’s ambition to accelerate its development in the fields of renewable energy and electricity, initiated in 2011 with the acquisition of SunPower,” said Patrick Pouyanné, Total’s chairman and CEO.

“It will notably allow us to complement our portfolio with electricity storage solutions, a key component of the future growth of renewable energy.”
