Weekend Read: A battery worth its salt
While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand.
Hitachi Energy, SP Energy Networks sign agreement to boost renewable energy flow from Scotland to England
Hitachi Energy will design and deliver a power quality solution that is expected to enable the transfer of around 280 MW of renewable energy capacity between Scotland and England.
Perovskite-perovskite tandem solar cell based on tin-lead top device achieves 28.20% efficiency
Developed by a research group in China, the two-terminal all-perovskite tandem device utilizes a 23.11%-efficient single-junction top cell relying on an optimized Sn-Pb perovskite material. The perovskite-perovskite cell was also able to retain 95.7% of the initial efficiency after being stored in a glovebox for 2,200 h.
K2 Systems launches mounting systems for facades
Germany’s K2 Systems has developed mounting systems that are specifically designed for facades, including walls made from masonry, concrete, sandwiched panels, trapezoidal metal sheets, and corrugated sheets.
New electrolyte for safer, more stable solid-state batteries
Researchers in Japan have discovered a stable, highly conductive material that can be used as electrolyte for solid-state lithium-ion batteries. The material’s ionic conductivity is said to be higher than any previously reported oxide solid electrolytes, with a wide operating temperature range.
Producing hydrogen via microalgae-bacteria coculture
A group of researchers has identified a multispecies bacterial community that could reportedly increase the efficiency of hydrogen generation via microbial metabolism. The proposed hydrogen system achieved a more than double production rate compared to common biological hydrogen production technologies.
Open-source software helps stakeholders make cost-effective renewable energy investments
Conceived by a group of scientists in Australia, the novel online tool can be modified for different regulatory environments. The program’s user interface asks for seven input files with a resolution of 30 minutes.
Belgian grid operator pays for residential PV curtailment
Fluvius, Belgium’s electricity grid operator, says it will compensate residential PV systems at €10.60 ($11.49) per kVa if they are not reconnected within 30 working days after a curtailment event.
Autarco releases three-phase hybrid inverters
Autarco has developed a three-phase hybrid inverter line, featuring 8 kW, 9.6 kW, 12.8 kW, and 16 kW versions and up to four independent maximum power point (MPP) trackers, along with a European efficiency rating of 97.5%.
