Younicos, the battery system developer bought by Aggreko last year, launched an energy storage rental service on the first day of Energy Storage Europe yesterday.

The Energy-Storage-as-a-Service rental offering is straight from Aggreko’s diesel generator business model playbook. It allows customers “to meet immediate storage requirements” said Younicos in a press release.

Younicos’s head of sales for Europe, Middle East and Africa, Alexander Schönfeldt, said: “This offer is straightforward: zero asset investment and no need for long-term commitment for 100% storage.”

The product is available immediately throughout the world, Younicos said. Offering batteries for rent is hardly a new idea, but with Aggreko’s leadership in the power system leasing market the Younicos news makes a lot of sense.

The announcement was just one of many made by leading energy storage names on Energy Storage Europe’s opening day. Purveyors of commercial and industrial-scale systems had a particularly busy time.  

Commercial and industrial product lines

Veteran battery maker Varta led the charge with the presentation of a modular commercial and industrial product line called Flex Storage that ranges from 20kW and 26kWh to 600kW and 750kWh.

“Thanks to the modularity of the product line, we can implement tailor-made solutions for industry, commerce and agriculture,” claimed Reiko Stutz, Varta’s general manager of commercial storage solutions.

Residential battery player Solarwatt also set its sights on the commercial sector, trumpeting the ability to link as many as five of its systems together to deliver up to 20kW and 60kWh of capacity.

The company’s MyReserve Matrix AC sensor meter has also been upgraded to allow the battery systems to take solar feeds of up to 250 amps, compared to 63 amps previously, Solarwatt said.

Elsewhere, power systems developer Socomec lifted the lid on its Sunsys Xtend energy storage system package, which combines 66kW upwards of lithium-manganese batteries with the firm’s PCS2 power conversion systems. 

Ancillary equipment manufacturers

Along with Socomec, this year saw a number of other ancillary equipment manufacturers making announcements at Energy Storage Europe. AEG Power Solutions, for instance, showed off a new storage converter, Convert SC Flex.

“The new system benefits of an enhanced power range up to 1MW for a single unit and provides an outstanding conversion efficiency factor for both the charging and discharging phases,” said AEG in a press note.

Austrian automation systems developer Bachmann Electronic also upped its energy storage market presence with the launch of a grid measurement module, GMP 232/x, designed for wind-connected batteries of up to 100kW.

“Besides manufacturers, the target groups include energy providers wanting to set up renewable energy power supply in off-grid regions, and industrial enterprises that assure grid stability using stationary storage,” Bachmann said.

Rounding off the ancillary equipment headlines at the start of Energy Storage Europe was the unveiling of a new battery inverter from Kaco New Energy. The 50kW Blueplanet Gridsave 50.0 TL3-S has an efficiency of 98.5%, Kaco said.  

Power-to-gas technologies

Another busy energy storage segment this year was that dedicated to hydrogen and power-to-gas technologies. Likely the most notable of these was a combined battery-plus-hydrogen storage system for residential use.

Launched by Germany’s Home Power Solutions, the Picea system was said to be “the world’s first compact unit for year-round power supply from solar.”

Remaining with more traditional hydrogen technologies, H-Tec Systems, which featured in last week’s Energy Storage Report, showed off its current electrolyser range.

The products on show included H-Tec’s ME 100/350 proton exchange membrane electrolysis machines, which can turn 5.4MWh of energy into 100 kilos of hydrogen a day, and its Series-S30 electrolysis stacks.

Combining power-to-gas with biofuels, meanwhile, Electrochaea displayed a portfolio of bioreactors, from 1MW to 50MW, which use surplus electricity and CO2 to create biomethane that can be added to natural gas supplies. 

Other companies at Energy Storage Europe

Among the other companies showing off their wares at Energy Storage Europe, Ads-Tec aimed to bridge the gap between energy storage and vehicle electrification with its StoraXe range, which includes fast chargers.

Bulk energy storage hopeful Gravity Energy exhibited a novel gravity power pumped storage technology, which is being piloted at a 1MW plant in Weilhelm, upper Bavaria.

And Nebuma, of Saarbrücken, Germany, touted a thermal energy storage system that could store around 16MWh of heat in a 20-foot container.

The company offers stationary or mobile tanks with blocks or granules heated to up to 1,300ºC, “with an efficiency that is second to none,” the company said.
