Energy Storage

The Chinese manufacturer said its new Nex E6000 and Nex E6000H storage systems combine a 6 kWh battery, an inverter, and an integrated energy management system, with scalable design allowing multiple units to be networked for higher capacity and coordinated energy sharing.

Researchers at TU Delft propose using 2D carbon selenide as a sodium-ion battery anode, offering a theoretical capacity of 589 mAh/g with minimal volume expansion. Computational studies confirmed the material’s structural and thermal stability, as well as tunable electrochemical properties, making it a promising candidate for large-scale, renewable-linked energy storage.

Lithuania-based Refra has launched its Oasis series of water-to-water heat pumps and chillers, offering capacities from 34 kW to 600 kW for small to large commercial and industrial applications. Featuring propane refrigerant, inverter-controlled compressors, and modular multi-circuit design, the units can reach a coefficient of performance of up to 5.1.

The European Union’s NIS2 Directive is pushing PV operators to strengthen both cyber and physical security, treating solar assets as critical infrastructure. It also highlights the need for stronger physical protection measures, such as site surveillance, access control, and perimeter security to prevent tampering and intrusion.

Icelandic utility ON Power has deployed a hybrid solar-plus-storage facility in Reykjavík to support electric vehicle charging infrastructure. The company says it believes such distributed systems will play a growing role in charging infrastructure in the future, even in Iceland’s renewables-dominated power system.

Marstek has unveiled a plug-in storage system with a two-kilowatt-hour capacity. The device plugs into a standard household socket and is designed to store solar power from balcony systems or draw in cheap electricity from dynamic pricing tariffs.

Australia has become one of the world’s most attractive destinations for hyperscale data centers, ranking among the top five to 10 markets globally by capacity. Drivers include large land availability in Renewable Energy Zones, renewable penetration exceeding 40% across the National Electricity Market (NEM), geopolitical stability, Five Eyes membership, and proximity to Asia-Pacific demand hubs.

The new series features single- and three-phase systems with scalable LFP battery integration. Designed for rapid whole-house backup and VPP applications, the new product delivers up to 89.6 % round-trip efficiency, according to the manufacturer.

US-based Pii Energy has launched a plug-in solar-plus-storage kit designed for renters and apartment residents, priced at about USD 2,400.

Newly-implemented rules governing Ukraine’s energy market introduce solar-plus-storage systems as a separate auction category, ease regulatory barriers governing standalone storage projects and establish processes for renewable energy facilities located in Ukraine’s occupied territories.
