Advait Greenergy opens 30 MW electrolyzer assembly facility in India
Advait Greenergy has launched a 30 MW electrolyzer assembly facility in Gujarat, India, with plans to scale capacity to 1 GW annually.
2D carbon selenide offers route to competitive sodium-ion batteries
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.
Refra debuts water-to-water heat pump for commercial, industrial use
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.
US residential solar set for 33% decline in 2026, says Roth Capital Partners
Roth Capital Partners says it expects a sharp drop in US residential solar installations as tax credit changes and Foreign Entity of Concern (FEOC) rules constrain financing.
How EU NIS2 is reshaping physical and cybersecurity for PV plant operators
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.
US says China not undercutting domestic battery anode makers
The US International Trade Commission (ITC) has blocked the imposition of anti-dumping and countervailing duties on Chinese active anode material (AAM), providing a massive sigh of relief for the domestic battery storage sector.
Pexapark registers 30 European PPAs for 2.2 GW in February
Swiss analytics firm Pexapark finds February saw the highest monthly volume of new European power purchase agreements (PPAs) since February 2024, including the longest PPA observed in the European market to date.
India’s 35 GW of renewables at risk of curtailment, warns Crisil Ratings
Crisil Ratings says rapid renewable energy additions and slow grid expansion could expose more than 35 GW of capacity to curtailment in India.
K2 Systems unveils elevated PV mounting solution for metal roofs
The K2 MultiRail High mounting system is a one-piece elevated solution with a height of 100 mm tailored to improve rear ventilation on metal roofs. K2 Systems says greater distance between modules and metal roof surface improves airflow and lowers module temperature, which can translate to higher annual energy yield.
Discovery of passivating pinholes in TOPCon solar cells paves the way for higher efficiencies
DAS Solar and Hebei University have identified two types of pinholes in TOPCon solar cells: harmful recombinational pinholes, which lack oxygen and cause carrier recombination, and beneficial passivating pinholes, which retain oxygen to enable efficient tunneling while maintaining interface passivation. Their work shows that optimizing oxide layer formation, back-surface polishing, and polycrystalline silicon deposition can increase passivating pinholes, boosting device efficiency and guiding industrial cell design.
