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.
Demand Energy installations are impressive… but it’s the invisible energy storage software controlling them that is the real attraction for Enel. Pic: Demand Energy.

Enel’s buyout of US project developer Demand Energy last week was largely down to a secret ingredient that has been cooking for several years.
While Washington State-based Demand Energy has a decent portfolio of projects in New York and closed last year with a microgrid deal in Costa Rica, the real lure for Enel is understood to have been its software platform, DEN.OS.
DEN.OS, which stands for ‘Distributed Energy Network Optimization System’, is a cloud-based platform for integrating energy storage and distributed generation that Demand Energy has perfected over the last eight years.
The market was of interest because the state’s Reforming the Energy Vision plan was creating new opportunities for storage to complement distributed generation in reducing demand, shifting load and adding resiliency. Read more →
GUEST POST by Rhys Walker, cost estimator, Glenmore Investments
According to the latest predictions, the cost of electric vehicles is likely to be the same as their internal-combustion counterparts by 2022, while by 2040 this price is predicted to become even lower.
Skeptics would say that predictions should not be taken too seriously as they are always to some extent based on merely subjective opinions. This is absolutely right, just like is the fact that electric car sales continue to increase.
Statistics say that global sales increased by approximately 80% in 2015 compared to 2014, from 315,519 to 565,668, while by the end of 2016 the number of electric cars on the world’s roads is expected to exceed 2 million.
By 2040, for instance, electric vehicles would account for 35% of all new vehicle sales. What this implies is that even if some years or numbers in such sort of predictions may be inaccurate, the tendency of sales growth is definitely strong and cannot be doubted. Read more →

Energy storage systems developer Demand Energy and Latin America microgrid pioneer Rio Grande Renewables this week announced a record-breaking project in Costa Rica.
The two companies have commissioned a battery storage-plus-solar-PV microgrid at Establishment Labs, a Costa Rican medical manufacturing plant, said Demand Energy in a press release.
The microgrid is said to be the largest in Central America and includes a 500kW, 1MWh lithium-ion battery connected to 276kW of solar PV.
The system is designed to provide multiple on-site and grid-assisting services, including peak demand reduction, solar variability smoothing and backup power for critical loads in the event of an outage.
It is controlled by Demand Energy’s Distributed Energy Network Operating System (DEN.OS™), which optimises how energy storage, distributed generation and other distributed energy resources interact and perform. Read more →
About 30% of storage procurement decision makers interviewed for the ESS study Beyond Four Hours said long-duration storage was “very important” for their business already. Image: ESS.

More than half of upcoming energy storage projects could require assets with a discharge duration of around four hours or more, according to new research.
About 30% of energy storage procurement decision makers interviewed for the ESS study Beyond Four Hours said long-duration storage was “very important” for their business already.
Another 30% said they were currently considering long-duration storage projects, 20% said it would be important in future and 10% considered it as part of a broader portfolio. Only 10% said it was not applicable to their business.
The research, carried out among energy storage procurers and project developers in association with Energy Storage Report, revealed a wide range of definitions for what constitutes a ‘long-duration’ asset.
But six out of 10 respondents claimed a requirement of more than four hours, which is generally considered beyond the cost-effective range of lithium-ion batteries commonly used for shorter-duration electricity storage. Read more →
Skeleton Technologies pitched to investors at The Business Booster in Barcelona (pic: InnoEnergy).
By Jason Deign
Skeleton Technologies is expanding its top team and contemplating further cash injections as its sets its sights on a precious German market.
The Estonian ultracapacitor maker, which has so far raised €26.7m in funding, is looking for a vice president of global sales as it expands manufacturing into Germany, which is expected to account for a fifth of its global market.
The company was also showing off to potential investors and customers at a showcase event called The Business Booster (TBB), in Barcelona, Spain, last Thursday.
Having closed its round C funding, for €13m, this summer, programme director Egert Valmra appealed to TBB’s audience for a round D injection in support of UCGEN3, a ‘next-generation’ ultracapacitor programme led by Skeleton.
In the meantime, however, Skeleton is focusing attention on scaling up production in Estonia and building a presence in Germany, where it opened a factory this year. Read more →
