I like to monitor multiple and parallel projects when I involve myself in something and a parallel project that qualify as parallel is the CMBLu and BALIHT EU project which involves multiple organizations and companies. To put it simple, this is a big project with the focus on organic lignin electrolyte which is far more environmentally friendly and less costly than your traditional vanadium RFB.
If you go to some of these project pages you will find that they reference Vanadium RFB as the electrolyte to overtake and that a +30% energy density over Vanadium RFB is achieved which mean that CMBLue organic lignin battery achieves 30 W-h/l - as a reference. This is bellow Lead-Acid 40 W-h/l but above the std Nickel-Iron Alkaline battery at 20-25 W-h/l
If we then look at the definition of what chelate is then Google describe chelate as: "a compound containing a ligand (typically organic) bonded to a central metal atom at two or more points"
Wikipedia describes Ligand as: "In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electron pairs, often through Lewis bases. The nature of metal–ligand bonding can range from covalent to ionic."
I searched on Chemisting's blog for the word organic under the Mn/Fe project pages and didn't find organic mentioned, which is a shame since organic flow battery is the trend of long term storage solutions and effectively, if it wasn't clear, Chemisting's Mn/Fe-chelate flow battery is of the organic type.

BALITH overview: A new generation of organic flow batteries shows promise for energy storage
The EU-funded BALIHT project is designing new redox organic flow batteries that can work at temperatures of up to 80 °C. Researchers claim that the batteries will offer longer duration, higher power and a 20 % higher energy efficiency compared to other organic battery types. The new battery will be based on low-cost, abundant organic molecules that are easily dissolved in water, electrolytes comprising lignin, thin non-fluorinated membranes and carbon electrodes. Redox organic flow batteries are one of the most promising approaches to sustaining a grid powered by the sun and wind, improving grid flexibility and stability and providing high-performance charge points for electric cars.
CMBLu overview:
The renewable energy transition needs powerful, scalable and affordable energy storage systems that do not harm people and nature. However, current options have been plagued with high cost, safety issues, environmental and social concerns. They are based on scarce resources that are extracted under ethically and ecologically questionable conditions with high energy consumption and transported around the world via long supply chains. Due to the rapidly increasing demand for batteries in the field of electromobility, there are going to be dramatic bottlenecks in the availability of these materials. For numerous applications, the flammability of existing battery systems is another major problem.
CMBlu’s Organic Solid-Flow Battery is different – and it is a first of its kind to be commercialized. Our technology is based on fully recyclable organic materials that are available all over the world. The aqueous electrolytes solutions are non-flammable and ensure an absolutely safe and reliable operation. Compared to previously established battery systems, our Organic Solid-Flow Batteries are characterized by free scalability between power and capacity. They can therefore be adapted precisely to the individual requirements of the respective application with corresponding cost advantages. The system-inherent separation of the electrolyte and the actual energy converter not only avoids self-discharge, but also enables the original performance to be restored by simply replacing individual components instead of the entire battery.
A clean and renewable energy future demands radical new concepts for energy storage. This truly green Organic Solid-Flow Battery disrupts the energy storage market to accelerate the transition and to meet climate goals sooner.
