Redox Reimagined

Abstract/Technology Overview

Our advanced redox solution stores energy in low-cost solid materials and produces power from the cell stack when the redox electrolytes are circulated through the storage tanks. We demonstrate the energy density is increased up to 5 times compared to the energy density of conventional systems. Our costs are much lower and have a wider range of operational temperature. Currently solutions for large-scale energy storage applications are prohibitively expensive and suffer from low energy density and narrow operation temperature range. Our redox battery technologies effectively address all of these barriers to adoption. The technology readiness of our technology is between 5 - 6.

Technology Features, Specifications and Advantages

The current trends to switch to renewable energy and electric vehicles increase the gap for affordable and high performing energy storage systems. This has led to the creation of new battery systems that can fill the gap. We have a portfolio of technologies consisting of Condensed-phase Aqueous Redox-flow Battery (CARB), Redox Flow Lithium Battery (RFLB) and Lithium Metal-Air Batteries, including novel catholyte, anolyte and membrane materials for these systems. Our proprietary technologies are next generation redox-flow battery systems and Metal-air battery systems that can provide various solutions to your business. For example, our battery systems can be used for:

  1. Energy storage during generation, transmission and distribution
  2. Ancillary support for smart grids
  3. Energy storage for varying scales of electricity generation
  4. Electricity buffer, at both residential and community levels etc. 

Potential Applications

Flow batteries are mainly used for large (1 kWh – 10 MWh) scale applications: 

Renewable Energy Storage: Storing energy from renewable sources such as wind or solar for discharge during periods of peak demand. These batteries can be used alongside solar or wind power sources to compensate for their fluctuating power levels.

Stand-alone power systems such as telecom base stations where no grid power is available.

Peak shaving and Load leveling: During periods of high demand, the flow battery system supplies power, reducing the load on less economical peak-generating facilities. Reducing investments in grid upgrades or in new energy generating capacity.

Smart grids: Flow batteries can be integrated with smart grids and microgrids for better control of energy storage and distribution during peak consumption times.

Electric Vehicles: Flow batteries can be rapidly "recharged". They can be used for applications where the vehicle needs to take on energy as fast as a combustion engine vehicle. Metal-air batteries are promising technologies for future generations of EVs.
