Flow Energy Storage Forschungsinstitut

As energy storage becomes an increasingly integral part of a renewables-based system, interest in and discussion around non-lithium (and non-pumped hydro) technologies increases. A team of experts from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technologies and the University of New South Wales take a deep dive

Are flow-battery technologies a future of energy storage?

Flow-battery technologies open a new age of large-scale electrical energy-storage systems. This Review highlights the latest innovative materials and their technical feasibility for next-generation flow batteries.

Which flow battery is best for long-duration energy storage?

Compared with the hybrid flow batteries involved plating-stripping process in anode, the all-liquid flow batteries, e.g., the quinone-iron flow batteries , titanium-bromine flow battery and phenothiazine-based flow batteries , are more suited for long-duration energy storage.

Are alkaline redox flow batteries good for energy storage?

Combining the low cost and high performances (Fig. 4 b), the alkaline all-iron flow battery demonstrated great potential for energy storage compared with the hybrid redox flow batteries, especially for long-duration energy storage. Fig. 4.

Are lithium–sulfur based flow batteries a good replacement for lithium–sulfur batteries?

Lithium–sulfur batteries with flow systems. From 2013, lithium–sulfur based flow batteries have been intensively studied for large-scale energy storage 18, 82 – 92 and are promising replacements for LIBs because of their high theoretical volumetric energy density (2,199 Wh l −1sulfur), low cost and the natural abundance of sulfur 86.

What is the'renaissance of flow batteries'?

To overcome these disadvantages, a growing effort has been focused on developing novel systems to increase energy density and operating voltage. This trend, which has been referred to as the ‘renaissance of the flow batteries’ (Ref. 6), is very similar to the interest in fuel-cell technologies in the early 2000s.

Are lithium–organic flow batteries a cost-effective EES system?

Lithium–organic flow batteries are attractive as cost-effective EES systems. The aforementioned lithium-based flow batteries that are based on heavy metals, metal complexes or toxic halogens have drawbacks (in particular, the solubility and availability of the redox couples) that hinder their widespread use as large-scale EES systems.
