Energy Storage

Investors are shifting focus from deployment growth to platforms that can orchestrate and monetize battery fleets.

The battery manufacturing heavyweight presented its latest sodium-ion products at ESIE 2026 earlier this month, expanding its push into grid-scale storage, AI data centers, and long-life applications.

The Korean manufacturer said its new heat pump system can achieve a seasonal coefficient of performance of up to 4.9 under low-temperature floor heating conditions, and approximately 3.78 under higher-temperature operation at 55 C.

Cloud and SaaS platforms are now central to PV plant operations, but their centralization creates a high-impact cybersecurity risk where a single compromise can expose or disrupt entire fleets of installations. Attackers exploit weaknesses like stolen credentials, insecure APIs, multi-tenant flaws, and platform vulnerabilities, making strong identity controls, secure APIs, and continuous monitoring essential defenses.

Taisei Corporation has demonstrated that a building can operate entirely on solar power by combining PV generation with a hybrid storage system integrating batteries and low-pressure hydrogen at a test facility in Yokohama. An EMS-enabled setup using lithium-ion batteries and PEM electrolysis balanced short- and long-term energy supply and demand, enabling year-round renewable operation, according to the company.

A study from the University of Naples Federico II finds hydrogen production at Mediterranean ports could cost €5.7–8.6/kg using only renewables and €2.5–13/kg in hybrid systems, with solar emerging as the most reliable resource and wind outperforming it in select locations. Alongside these findings, major industry developments include new hydrogen and e-fuel projects, advanced electrolyser technologies, and EU-backed infrastructure expansion supporting large-scale decarbonization.

Norwegian developer Scatec ASA has commissioned the first phase of the 1.1 GW Obelisk solar and battery energy storage system (BESS) project in Egypt, backed by $479.1 million in development finance institution (DFI) debt and a fully contracted storage revenue model.

A new metric for assessing total system costs puts a least-cost mix of offshore wind and solar at about €46 ($54.20)/MWh in a future climate-neutral energy system for Denmark. Researchers tell pv magazine that figure is less than half the equivalent cost of nuclear under the same conditions.

Researchers in the United Kingdom found that thermostatic radiator valves can reduce air-source heat pump space heating energy use by 6–8% without affecting system efficiency when used correctly. TRVs must be applied carefully in well-designed, balanced systems with at least one open flow path, as they mainly serve as a secondary tool for room-level comfort control rather than a replacement for proper heat pump design and low flow temperature operation.

India-based Pur Energy has launched the PuREPower 3.0 Lite, an all-in-one lithium battery-based power backup solution positioned as a cleaner and more compact alternative to conventional inverter and lead-acid battery combinations for the residential segment.
