Long time coming: Part 2

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the second of a two-part special report, Andy Colthorpe dives deeper into questions of bankability, market segmentation and manufacturing strategies with four very different providers of flow energy storage technology.

Cellcube’s ‘highly vertical’ ambitions for long duration redox flow batteries

The fortunes of Gildemeister’s redox flow battery energy storage have been an interesting mirror to those of the technology class overall in some ways. Energy-Storage.news spoke to a leading representative of those assets' new owner, CellCube Energy Storage company president, Stefan Schauss.

Flow in flux: Long duration batteries in fight to commercialise

It’s been predicted for some time that the redox flow energy storage space will, after some turmoil and rapid consolidation, find success in providing energy storage at durations of more than four hours. This past couple of weeks have been a tale of both turmoil and success.

UK’s new de-rating factors a boost for long duration batteries and energy arbitrage

UK’s new de-rating factors a boost for long duration batteries and energy arbitrage

Changes to the de-rating factors for battery storage projects competing in the UK's Capacity Market (CM) will push the sector towards longer-duration batteries, while potentially sparking a shift towards energy arbitrage as a source of revenue for shorter duration applications. David Pratt heard from several industry sources following last week's announcement.
