redox flow

Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.

German production equipment provider Schmid and Saudi chemical group Sabic are planning to begin activities at a new factory in Saudi Arabia, with production being expected to begin in 2021.

Matt Harper, chief commercial officer of newly-merged British-Canadian vanadium redox flow battery business Invinity Energy Systems has spoken to pv magazine about the VS3-022 Battery Unit it is marketing for grid scale solar-plus-storage projects and why it may be a better bet than lithium-ion.

U.S. researchers claim to have added iron sulfate to anthraquinone disulfonic acid in a redox flow battery for the first time. The scientists said the combination could lead to inexpensive and more stable redox flow storage for just $54/kWh and said $66/kWh is already possible.

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.

An international research group led by CIC EnergiGUNE, a Spanish research center, is designing new redox organic flow batteries. The researchers claim the batteries will offer longer duration, as well as higher power and energy densities, in a more environmentally sustainable format. The European Commission provided €3.8 million in funding for the initiative.

Lead, sulphuric-acid, nickel, cobalt and rare earth metals are highly toxic and have adverse impacts on the environment and the societies in which they are mined. As the EU is looking to become a world leader in battery production, a report considers new battery technologies – such as sodium-ion – which would have less negative impacts.

German equipment supplier, Schmid Group has announced the successful delivery and installation of three of its Everflow energy storage systems to a leading PV cell manufacturer in China. These are the first storage systems delivered to China by Schmid, and will be used in combination with large-scale PV projects.

A team of scientists from the U.S. University of Rochester has developed a compound, which it says could double the effectiveness of redox flow batteries, and “transform the energy storage landscape”.

Australian stock exchange-listed battery maker Redflow has announced a AU$14.5 million ($11.25 million) funding round, as the Brisbane-based company takes its manufacturing base offshore and turns its attention to a market “sweet-spot” including the off-grid, telecom, commercial and industrial sectors.
