New power electronic device to manage surplus solar power–Part II
The first pilot tests have been conducted for the EU-funded project ‘renewable penetration levered by efficient low-voltage distribution grids (RESOLvD). pv magazine has looked into the demonstrator and the related energy sharing algorithm.
Hybrid operational strategy to use lithium-ion storage in commercial PV arrays
Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.
Rosatom plans 2 GWh lithium-ion battery factory in Russia
Russian nuclear energy giant Rosatom has acquired a 49% stake in Enertech International, a South Korean lithium-ion battery specialist, and has announced plans to build a gigafactory at an unspecified location in Russia. The start of production is scheduled for 2025.
Australian government praises vanadium project
The Australian government has recognized TNG’s flagship Mount Peake Project – a mine that includes production plans for vanadium redox flow batteries and green hydrogen – as nationally significant.
Solid-state batteries in space
Japanese scientists are about to launch solid-state batteries into space.
A ‘chemical fuse’ – voltage sensitive polymers in the fight against battery fires
A team of researchers from St. Petersburg say they can build a circuit interruptor that works directly into the current collector. The device operates via chemical reactions and would be thus more reliable than current battery monitoring system approaches.
Six new ways to boost battery energy density
Scientists in the UK developed a model to explain one of the challenges to harnessing an oxygen-redox reaction in certain cathode materials for lithium-ion batteries. Based on their improved understanding of the reaction, they suggest several possible routes for further research to avoid the unwanted reactions and develop reversible, high energy density cathode materials.
Australia to support battery production with $1.2 billion funding initiative
Lithium-ion battery manufacturer Energy Renaissance has welcomed a new AUD 1.5 billion ($1.2 billion) Australian government initiative to boost processing of critical minerals for batteries, solar panels, and wind turbines.
Spain joins the gigafactory race
SEAT and Iberdrola are planning to build an EV battery manufacturing facility in Barcelona with the support of the Spanish government.
Australian mining company moves ahead with 1 GW green hydrogen project
Province Resources is pushing ahead quickly with its plan to develop a 1 GW hybrid solar PV and wind farm in Western Australia as part of a proposal to produce renewable hydrogen for domestic and foreign markets.
