Imergy is a world-leading battery storage company that addresses the key challenges of energy storage



  • Imergy combines the power of proprietary chemistry and advanced technology to deliver groundbreaking sustainable solutions for storing and sharing energy. 
  • Its Energy Storage Platform (ESP) allows users to scale up power and storage capacity independently of one another, making it far more flexible and cost-effective than any other battery available


  • Battery storage is the most crucial element in the renewable energy business due to the intermittent nature of primary energy sources such as wind and solar
  • Imergy technology is world class and they have partnerships with corporations and governments in Europe, US, Asia and Africa
  • There is a huge market opportunity within US, Asia (particularly India) and Africa


  • Bill Watkins – former CEO of Seagate and Bridgelux
  • Tim Hennessy – former president of Prudent Energy (Chinese flow battery manufacturer), and CEO of VRB Power Systems
  • CFO Jack Stark was former CFO of BrightSource and Silicon Valley Bank
  • “Venture Investors” – NEA, Draper Fisher Jurvetson, Blue Run Ventures



  • Imergy received major press coverage in Forbes in May 2015 as a major rival to Tesla’s battery technology
  • In discussions with potential partnerships for MicroGrid projects in India – EIP assisting with this effort
  • Signed a deal with Juno Capital Group to bring Imergy’s vanadium flow batteries to telecom companies in China. Imergy will sell flow batteries to Juno and Juno will then develop ways—leasing, storage as a service

Imergy’s Flow Batteries vs. Other Technologies

Imergy’s ESP transforms batteries from consumables into long-life assets.

Compared to conventional lead-acid and lithium ion batteries, Imergy’s flow batteries offer unlimited cycles, charge quickly, retain charging capacity indefinitely, and can tolerate extreme temperatures without exploding, all with lower environmental impact.

Therefore, Imergy’s systems perform better over much longer time horizons, and have lower lifetime costs than lead-acid and lithium-ion batteries.


Imergy’s Energy Storage Platform (ESP) is based on redox flow battery technology, the most cost-effective and reliable energy storage solution available today.


  • A flow battery is charged and discharged by a reversible reduction-oxidation reaction between the two liquid electrolytes of the battery
  • Unlike conventional batteries, electrolytes are stored in separated storage tanks, not in the power cell of the battery
  • During operation these electrolytes are pumped through a stack of power cells, in which an electrochemical reaction takes place and electricity is produced
  • The design of the power cell can be optimized for the power rating needed, since this is independent of the amount of  stored energy


  • Reliable and consistent power availability enabled by fast charge and discharge times
  • Customized, separate power and capacity specifications for different applications
  • Unlimited cycle life due to no solid state reaction 
  • Durable operations in rugged, remote outdoor environments from -20°C to 55°C ambient.
