First AI-based control method for vanadium redox flow batteries
Australian researchers are proposing a novel, learning-based H∞ control method to enhance the performance of vanadium redox flow batteries in DC microgrids.
High-energy, membrane-free organic redox flow battery
US researchers have developed a new high-voltage, membrane-free, nonaqueous lithium-based organic redox flow battery. They say that the elimination of the membrane decreases the upfront costs of the battery by as much as 30%.
Distributed PV, battery storage curtailment in low-voltage networks
University of New South Wales (UNSW) researchers have looked at energy losses in South Australia and have identified average curtailment of 1.5% for distributed PV sites and 0.2% for distributed PV coupled with batteries, but some locations experience generation losses of up to 25%.
Anode-less redox flow batteries capable of fast cycling
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
The case for hard carbon-based sodium-ion batteries
Researchers in China have summarized the technical issues hindering the development of hard carbon, which is regarded as the most promising anode for high-performance, commercial sodium-ion batteries.
Romania to launch first CfD renewable energy auction
Romania is set to launch its first auction for a contracts-for-difference (CfD) support scheme later this month. It will tender 2 GW of solar and wind capacity, backed by 15-year power purchase agreements (PPAs).
Eaton introduces overhead EV fleet charging solution
Eaton, an Irish energy management specialist, has developed EV Charge Busway, an overhead power distribution solution that eliminates cable runs and major modifications to existing parking and conveyor structures.
Carbon-cement supercapacitors for bulk energy storage
The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with inexpensive, abundant precursors – cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.
Weekend Read: Much more than Goodenough
The world would have been a different place today had John Goodenough accepted the Shah of Iran’s $7 million offer, in 1974, to carry out solar research. Instead, he secured a job as the head of inorganic chemistry at the University of Oxford. During his tenure, he made a lithium-ion battery discovery that would affect the lives of almost everyone.
Croatia adopts legal framework for agrivoltaics
The Croatian government has adopted bylaws to the Spatial Planning Act that define agrivoltaic installations and the areas in which they can be deployed, in order to facilitate future deployment.
