IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.

Greece’s PPC Group has finished construction of its 2.13 GW solar portfolio in northern Greece. The company is now working on its third large-scale battery storage facility in the area, with plans for two pumped-hydro storage projects also progressing.

A new sodium-ion cell for ESS may further improve competitiveness in large-scale systems against the weight of the lithium-ion battery sector.

Battolyser Systems and VDL Hydrogen Systems have merged to form Alquion, while Ming Yang Smart Energy Group plans to invest more than $10 billion in hydrogen and renewable energy projects in Ethiopia.

Lambda Wärmepumpen GmbH said its Eureka heat pump series uses a patented fluid mechanics system that reportedly improves heat transfer by four to six times while maintaining a temperature difference of just 3 K between the air and the refrigerant. Its seasonal coefficient of performance ranges from 4.50 to 6.10.

Croatian power company Hrvatska Elektroprivreda is seeking a developer to build a 56 MW solar power plant tied to up to 200 MWh of battery energy storage. The deadline to submit expressions of interest is May 12.

An international study has demonstrated that utility-scale solar PV paired with hydraulic hydro storage (HHS) could reach an LCOE as low as $0.022/kWh in select U.S. regions. The system could provide GWh-scale, cost-competitive, and highly reliable long-duration storage, capable of powering large commercial districts with minimal environmental impact.

Chinese power transformer manufacturer TBEA introduced a grid-forming string power conversion system (PCS) for utility-scale storage, renewable energy base projects, and weak-grid applications. The TE435/392K-HV-BL high-power converter focuses on improving power density and grid support. According to TBEA, its fully integrated liquid-cooling design increases volumetric power density by 78% and gravimetric power density by 32% […]

The US manufacturer has launched a modular residential battery for Europe, scalable from 7.3 kWh to 47.9 kWh with LFP chemistry and IP65 protection. The system offers up to 23.3 kW nominal power, over 6,000 cycles, and a depth of discharge of 90%.

Indian clean-tech startup Greenvize has launched a compact hydrogen-based cooking system designed for residential and commercial kitchens. The system integrates a proton exchange membrane (PEM) electrolyser directly into a cooking unit, enabling on-site hydrogen generation from water without the need for storage or distribution infrastructure.
