What is a flow ba4ery?
• First explored in the 1970s
• RelaLvely li4le investment
compared to Li-ion
• Cost-effecLve at scale
• Long lifeLme
• Best for long-discharge
(energy) applicaLons

chemistry for the future of energy storage
• Non-toxic and contain earth-abundant atoms
• Can be synthesized at industrial scale
• Inexpensive compared to Vanadium
• Undergo extremely rapid redox reacLons
• Permit use of inexpensive membrane
• High energy density
• Stable and long-lived
• Can be tuned through organic chemical synthesis to improve cell
performanceResearch and commercial development
• Research support from ARPA-E
• Exclusively licensed to Green Energy Storage for commercial development
