Energy Storage

Researchers have found strong anodic activity in disordered particles of magnesium chromium oxide. Unlike conventional, ordered nanocrystals, the disordered particles reportedly achieved reversible magnesium extraction and insertion.

Batteries, and the raw materials that make them, are a frequent target of public criticism. The high water consumption required for lithium extraction is speeding up desertification around the salt lakes of Latin America’s “lithium triangle”, for example. The mining debate highlights general problems with the extraction of raw materials including copper, crude oil and lithium but international companies can still influence extraction methods – and there are plenty of different approaches.

Storage system providers in Europe have told pv magazine output has thus far been unaffected by the virus outbreak in China. Manufacturers are aware, however, the situation may change rapidly if self-isolation measures taken by the authorities continue.

Australian peer-to-peer (P2P) energy trading pioneer Power Ledger has won a lucrative contract with Alperia SpA, one of Italy’s largest renewable electricity utilities.

A new paper published by researchers at China’s Tianjin University examines the state of the art in grid level energy storage, outlining the pros and cons of various battery technologies being deployed on grids around the world, and remaining challenges that could be overcome if research is pushed in the right direction.

Under Tennet’s most optimistic outlook, solar generation capacity could more than double the volume of wind farms by the end of the decade, provided the Netherlands goes above and beyond Paris Agreement climate change requirements.

The luxury car maker is betting on the timely development of market-ready solid-state batteries. Mercedes will work with the Canadian research institute to quickly integrate new technology into field applications to cut development cycle times.

Electronics corporations Panasonic, Kyocera and LG have filed results for the nine months to December 31. All three reported uplifts because of their solar activity and LG has said it will dive deeper into energy storage. Panasonic is deepening its commitment to automotive batteries through a new joint venture with Toyota.

Pumped hydro and battery projects, coupled with renewables, offer the world’s lowest peak clean electricity tariff. The tender, which received bids for for 1.62 GW of capacity against the 1.2 GW sought, saw Greenko secure 900 MW of pumped storage capacity and Renew Power 300 MW of battery storage.

The South African utility is seeking offers for the supply of 1,383 320 W polycrystalline modules and mounting structures, to be used for the construction of four off-grid PV projects at its research center.
