"The largest hybrid energy storage project in Jiangsu Province, China, has officially been put into operation!" The project is 200MW / 400MWh, combining both lithium and vanadium flow batteries. Although the break down of each technology is not provided, one can deduce from the photo that it is mostly lithium batteries, with 38 lithium batteries and 24 vanadium ones. Bear in mind that the lithium ones will hold much more energy in each battery. The photo is more insightful than the article, as it shows how these are configured. Both technologies are separating the inverters from the DC blocks. Furthermore, unlike the lithium batteries, the vanadium DC blocks are not fully containerised, with the power module in the 20 ft (6m) container but the electrolyte tanks separated. This is a good example where a design that used larger (and taller?) tanks could increase the energy of the vanadium battery without changing its power components (and without increasing its footprint). #BESS #ESS #lithium #vanadium #VFB #LFP #batteries #LDS #energystorage https://lnkd.in/gJ2U5sCg

Hi Fortune , can we connect on johan@deepsouthresources.com ? Kind regards
Also curious on the reason for the hybrid storage model. Havent seen this combo before.

6moThank you for sharing that photo! Mikhail Nikomarov It would be interesting to see how the site makes use of the advantages of the different electro-chemistries and how the configuration, seen in the photo, would reflect that. For example, I believe the flow batteries have much better cyclical lifespans while the lithium have better round trip efficiencies. So if the flow batteries provided some form of baseload, then how often and how much lithium is committed?
