Berlin-based Boreal Light has developed water desalination tech powered by PV for off-grid applications. The solution uses 460 W solar panels from Chinese module manufacturer DAH Solar and produces clean water from direct seawater at a cost of €0.50 ($0.78)/m3.
A group of researchers from Helmholtz-Zentrum Berlin (HZB) has achieved a new world efficiency record for a silicon-perovskite tandem solar cell, with a certified efficiency of 32.5%.
University of Queensland spin-off Pure Battery Technologies which has developed a greener, cheaper process for refining critical battery materials has received a $57.45 million (USD 38.5 million) loan from the European Investment Bank to build a demonstration plant in Hagen, west Germany.
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
AMG Advanced Metallurgical Group has energised its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.
Germany has decided to build its first green ammonia import terminal in Hamburg, in collaboration with Air Products. Egypt, meanwhile, has signed $128 billion of hydrogen framework agreements.
Australian independent power producer ReNu Energy has signed a deal with the developers of a proposed 3.5 GW solar-plus-storage facility in Indonesia to explore the potential large-scale production of green hydrogen for supply into Southeast Asia and beyond.
German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.
Researchers led by Germany’s TÜV Rheinland have created a database of technical risks and mitigation measures for PV installations. Their broad overview of quantification methods has shown that further standardization is required.
Qingdao University researchers have synthesised high-performance titanium dioxide-based anode materials with excellent cycling stability, while German scientists have used operando techniques to observe how solvated sodium ions embed themselves in electrodes.
