EnerVenue, developer of lithium-free nickel-hydrogen batteries, has signed its first multi-megawatt-hour commercial order: 11 MWh with a major Chinese oil and gas producer. Announced on 23 September 2026, the order covers 26 containerised Energy Prism units that will store solar power at an oilfield in northern China.

Shifting daytime solar to peak hours

According to the company, the systems will shift the site’s daytime solar output to peak demand hours. Three units will ship in December 2026 and 23 in March 2027. The customer was not named; EnerVenue says safety was the primary selection factor.

Water-based, non-flammable electrolyte

The Energy Prism units use EnerVenue’s fourth-generation Aqueous Metal Cell (AMC), a nickel-hydrogen chemistry with a water-based, non-flammable electrolyte, designed for 30,000 charge cycles – up to three cycles a day for 30 years. The company says the cells passed UL 9540A fire propagation testing with no fire at cell level.

CEO Henning Rath said an oil and gas producer does not put new technology on a working site unless it is completely satisfied that the safety case is sound. CTO Dr Majid Keshavarz said the AMC chemistry does not produce the progression of events that leads to ignition, fire or explosion.

New line in Changzhou

The units will be made at the company’s new facility in Changzhou, Jiangsu, which opened on 24 September 2026. Phase 1 capacity is 250 MWh a year, with plans to reach 1 GWh in 2027.

Greenvolt Power has started construction of the 600 MW / 2.4 GWh Siedlce battery energy storage project in Poland. Announced on 24 September 2026, the project will become Poland’s largest and one of Europe’s largest battery storage facilities, according to the company. Commercial operation is planned for the end of 2027.

210 battery containers from BYD

According to Greenvolt, BYD Energy Storage is supplying the batteries. The facility will comprise 210 battery containers and 105 transformer containers with power conversion systems. P&Q is responsible for engineering and construction and ONDE for the electrical infrastructure.

1 GW / 4 GWh in Poland

Greenvolt’s 200 MW / 800 MWh Turośń Kościelna facility has been operating since July 2026, while the Ełk project of the same size is expected online in the fourth quarter of 2026. Together with Siedlce, the three projects will total 1 GW / 4 GWh. The company’s probability-weighted BESS pipeline stands at around 4.6 GW, of which about 2.4 GW is in Poland.

João Manso Neto, CEO of Greenvolt Group, said that with Siedlce the company is once again moving from plans to delivery, adding that Poland is a key market and battery storage is becoming an increasingly important part of its growth.

FRV Australia, owned by Jameel Energy and OMERS Infrastructure, has commissioned the 100 MW / 200 MWh Terang battery energy storage system (BESS) in Victoria – its first standalone, utility-scale battery project in Australia. The commissioning was announced on 30 September 2026.

48 containers, 38 inverters

According to the announcement, the facility uses 48 SolBank 3.0 battery containers manufactured by e-Storage and 38 SMA inverters. Canadian Solar was the EPC contractor and TEC-C the balance-of-plant contractor. The plant runs on grid-forming inverter technology supported by an AUD 7 million grant from the second round of the Victorian Government’s Energy Innovation Fund. Construction created around 40 full-time-equivalent roles.

Gnarwarre next

FRV Australia’s 250 MW / 500 MWh Gnarwarre BESS is under construction and targeted for completion at the end of 2027. The company also has a pipeline of standalone BESS and solar-plus-storage hybrid projects in New South Wales, Victoria and Queensland.

Michael Steiner, CEO of FRV Australia, described the commissioning of Terang as a defining moment for the company, demonstrating its ability to develop and operate utility-scale dispatchable energy infrastructure.

As part of the project, FRV Australia also sponsored the Australian Indigenous Education Foundation (AIEF) and the Terang Mortlake Netball Club.
