GenCell, an Israeli fuel-cell maker, yesterday trumpeted a major win as part of an under-the-radar strategy to get utilities relying more on hydrogen.
The company said San Diego Gas & Electric (SDG&E), the Californian utility, would be installing GenCell G5rx fuel cells for substation backup power.
Bloomberg reported the deal would cover an initial three substations, with 27 more to follow within three years. SDG&E is keen to use fuel cells as a way of extending the backup power capacity at substations.
Backup power is a technical requirement at all utility substations. It is used to keep high-voltage circuit breakers open whenever there is a loss of power on the grid.
Most substations are equipped with lead-acid battery arrays that can supply backup power for up to eight hours. Beyond this, the utility usually has to switch to an alternative power source, such as a diesel genset. Read more →

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.

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. Read more →

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. Read more →
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. Read more →
