Battery storage

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.

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.

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.

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.

A new global dataset of 119 energy-sector cyber incidents from 2022–2024 shows EU and BRICS countries, followed by the US, are most affected. Attacks targeted power, oil, gas, and nuclear infrastructure, driven by both financial and political motives, with diverse threat actors involved.

Researchers at Germany’s Fraunhofer FKIE institute developed PowerRange, a virtual simulation platform that helps power grid operators safely test cybersecurity measures and respond to realistic cyberattacks. The platform supports both traditional and renewable grids, offering immersive training across IT, OT, and control systems while highlighting the importance of coordination, communication, and practical defense strategies.

The new prototype ranks among the most advanced sodium‑ion battery systems reported worldwide.

Australia’s rooftop solar market has bounced back into record-setting territory with 281 MW of new capacity registered across the country last month, marking the largest February total on record.

The electricity grid is a real bottleneck for energy in the United States, and it’s not only utilities and grid operators who are struggling. Grid congestion also puts pressure on renewable energy project owners and is as much a business problem as it is a technical one, writes Alon Mashkovich, CEO of energy management business software supplier enSights.

Malaysia’s rising power demand, driven by industrial growth and data centers, is exposing grid and capacity constraints, prompting policies like Corporate Renewable Energy Supply Scheme (CRESS) to enable corporate renewable procurement while maintaining system cost recovery. A key factor is the System Access Charge (SAC), whose uncertain future trajectory affects long-term solar PPAs and investment decisions, making scenario-based modelling crucial for assessing project bankability.
