Siemens Gamesa tests redox flow ‘BESS hybrid’ in Spain

A vanadium redox energy storage system is being tested in Spain by Siemens Gamesa Renewable Energy (SGRE) as part of a hybrid renewables project.

SGRE said the next-generation redox flow battery at its La Plana test site near Zaragoza offers a 120-kilowatt energy output with 400 kilowatt-hour storage capacity.

Utility plans pioneering underground redox project

A subsidiary of German utility EWE has unveiled proposals to build “the world’s largest redox flow battery” in the country’s underground former salt mines.

EWE Gasspeicher has teamed up with researchers at Germany’s Friedrich Schiller University in Jena to work on the Brine for Power (B4P) project that involves deploying an electrolyte solution pioneered by the university team.

Liquid power for future computer is under development

Researchers at ETH Zurich and IBM Research Zurich have built a miniature redox flow battery that can supply electric power and dissipate heat simultaneously for computers.

The group, led by Dimos Poulikakos, Professor of Thermodynamics at ETH Zurich, used liquid electrolytes as a medium to deal with heat dissipation and taking out that heat generated by the processor via the same circuit.

Bigger and better redox flow to enter the large-scale ESS market

Bigger and better redox flow to enter the large-scale ESS market

A Japanese company is set to launch a redox flow battery onto the large-scale energy storage market that it claims will boast higher capacity at a cheaper rate than its previous products.

Sumitomo Electric Industries plans to release the scalable 500kW/h per unit ESS this autumn.

Situated in a conventional cargo container, the all-in-one design incorporates the battery’s liquid tanks, pump and all the necessary devices.

The market for large storage batteries has been growing around the world, driven by the increase of renewable energy generation, which needs a stabilising buffer between it and the grid.

In Japan, a feed-in-tariff programme introduced in 2012 to promote the use of renewable energy has boosted demand for large storage batteries.

Large storage batteries are a main product in Sumitomo Electric's energy- and environment-related businesses.

Back in 2012, Sumitomo completed a 1MW redox flow battery electric power generation/storage system on the premises of its Yokohama Works.

The system was developed in cooperation with Nissin Electric Co,  Sumitomo Densetsu Co and Meidensha Corporation in the respective technical fields.

US laboratory testbed to use ViZn 128kW flow battery system

US firm ViZn Energy Systems is to deliver a 128kW/ 320kWh redox flow battery system for use in a US laboratory’s microgrid research, development and demonstration testbed.

The order for the system, based on its zinc-iron chemistry, was received from Idaho National Laboratory (INL), part of the Department of Energy’s (DOE) complex of national laboratories.

German funding to cut redox flow battery costs

A cash boost from the German government will allow a multi-agency joint R&D project to develop better and cheaper bi-polar plates for redox flow batteries.

The country’s Ministry for Economic Affairs and Energy (BMWi) has provided €3.9 million funding for the “extruded plate” project,
