Digital adoption across the renewable energy value chain reveals a stark imbalance. Operations and maintenance (O&M) has embraced digitalization most enthusiastically, with SCADA systems and IoT-enabled devices revolutionizing efficiency through real-time monitoring and resource optimization. However, engineering, procurement, and construction (EPC) processes remain surprisingly under-digitized despite their critical importance.

The researchers say the photo-assisted, self-chargeable aqueous Zn-ion energy storage device demonstrated a remarkable 170% increase in charge storage capacity at a constant current density of 0.02 mA/cm2 under consistent light exposure. Self-charging took 140 s to reach the potential of 0.9 V.

Australia’s rapidly growing solar PV industry faces mounting cyber risks that no operator can afford to ignore. PV systems rely on intricate supply chains, incorporating hardware and software from multiple vendors. Each link in this chain – be it a component manufacturer, a software provider, or a maintenance contractor – can introduce potential entry points for cyberattacks.

Bharat Petroleum Corp Ltd (BPCL) will establish hydrogen refuelling infrastructure for the hydrogen-fueled vertical take-off and landing (VTOL) aircraft developed by BluJ Aerospace. It will also design and develop an indigenous proton exchange membrane (PEM) hydrogen fuel cell with high power density to facilitate vertical lift-off.

This is a proof-of-concept 1.22 kg laptop with a solar panel integrated into the lid, capable of absorbing enough sunlight in 20 minutes to power the device’s video for an hour.

Japanese researchers have engineered a 100 cm² perovskite solar cell module featuring a robust single-walled carbon nanotube (CNT) electrode to improve durability and enable dual-sided light absorption.

Charge Robotics partnered with Solv Energy to pilot a portable factory system intended to make solar installations safer and more efficient for increasingly challenging terrain.

Adani Green Energy (AGEL), with over 12.5 GW of operational renewable energy assets, has committed to achieving net water positivity across all its operational locations by 2025-26.

To make it easier to adopt building integrated PV (BIPV) as a glazing material, a group within the IEA Photovoltaic Power Systems Programme (IEA-PVPS) has tackled the solar heat gain coefficient (SHGC) calculation for BIPV. It is part of IEA PVPS Task 15 international standardization efforts.

A research group in India has embedded a hybrid heterojunction solar cell as a bottom device in a four-terminal perovskite-silicon solar cell using a solution processing technique. The novel cell architecture, according to its creators, could be produced at significantly lower costs compared to conventional perovskite-silicon tandem designs.
