Solar-Charged Batteries Are The Future

StorEn Technology is developing evolutionary vanadium flow batteries. Incubated at the Clean Energy Business Incubator Program (CEBIP) within Stony Brook University in New York, we're building upon the strengths of vanadium flow batteries to revolutionize the world of residential and industrial energy suppliers. 

Our batteries are being developed to deliver superior performances at a lower cost, and fulfill market demand for more efficient and cost-effective energy storage. StorEn takes what vanadium batteries already promise - durability and sturdiness - and use extensive R&D to focus on improving the electrical efficiency of the stack, the energy density of the electrolyte, and the module. Through these processes, we create efficient, powerful, effective products which have led to four US provisional patents and four trademarks so far.

StorEn answers the call for long-lasting, and economical, energy storage.

Invest in StorEn. 

Our disruptive patent-pending all-vanadium flow battery technology for energy storage delivers the lowest cost per cycle in the world, eight times lower than lithium-ion batteries.

With a battery life of 25 years and over 15K cycles, our batteries support market demand for efficient, durable and cost-effective energy storage, enabling self-consumption of self-produced electricity and the transition towards a carbon-free economy.

The Offering

$4/share of Common Stock│When you invest you are betting the company’s future value will exceed $26M.

Our mission is to develop innovative, efficient, resilient and cost-effective energy storage. We'll enable the renewable revolution to combat climate change.

Our Batteries 

A StorEn battery module will work in synergy with the solar system. During the day, our solar panels capture energy from the sun. This energy charges the battery while simultaneously powering a home, office, or business center. Then, as day turns to night, the battery takes over, providing energy consistently, and maximizing each hour of the day for energizing efficiency.

Independent from its solar storage capabilities, the StorEn battery module can store power from the grid at night when electricity prices are low. By using battery power during peak electricity times, clients can save money on their utility bills. Additionally, in the event of an emergency, our patent pending battery design guarantees continuity to vital devices such as telecommunication, lighting, refrigeration, and heating and ventilation systems. StorEn delivers additional assurance in case of a natural disaster.

Our customers can save money while benefiting the environment.

"Your next home could run on batteries. Solar-powered batteries have the possibility of saving consumers money in the long term."


Our home batteries charge using electricity generated from solar panels. When the sun goes down, our battery uses energy it drew throughout the day to power the home through the evening. 

Home batteries recharge when electricity rates are low, and use that energy later, when prices spike. Plus, they provide backup electricity supply for added security in the event of an outage. 


Our home battery will be cost-effective, easy to install and connect, and will offer households an energy alternative to the utility grid.


Our industrial batteries charge using the electrical energy from intermittent power sources like wind and solar. 

These will be able to store energy from virtually any source when production exceeds consumption, and excess energy is generated.


When production falls below consumption, our ideal industrial battery will reduce power waste by using energy it's already stored.

Telecom-Data Centers

Our Telecom Center Batteries charge from the grid, and are powered with renewable energy in off-grid locations. 


This will be a battery for Data Centers that provides a backup electricity supply for added security.


Our ideal battery for Telecom Towers and Data Centers will enable continuity of communication, transmissions, and, data integrity.

More About Vanadium Flow Batteries 

Lithium Batteries vs. Vanadium Flow Batteries

While the initial price point of lithium batteries might be enticing, vanadium flow batteries last longer and cost less over their lifetime.

Lithium-ion batteries lose some of their original capacity over time. This decay in capacity can be in excess of 50% after only 3 years. Additionally, the safety of lithium-based batteries attracted much media coverage as they can catch fire and sometimes explode.

Tesla's Lithium Powerwall™Battery

  • Delivers 13.5kWh energy and comes with a 10-year warranty
  • Cost per kWh: $459 ($6.2K ÷ 13.5)

StorEn's Vanadium Flow Batteries

  • StorEn lifetime is 25 years without any decay
  • StorEn Cost per kWh already comparable, despite lithium batteries being already manufactured in large volumes

Vanadium Batteries Are The Clear Winner

"Lithium-ion batteries... are no match for VRFBs, which have longer lifetimes, can be scaled up more easily, and can operate day-in / day-out, with no significant performance loss for 20 years or more."

Institute of Electrical and Electronic Engineers

October 26th, 2017

Although the vanadium flow battery (VFB) technology has been around for some time and boasts strong fundamentals, demonstrated by a number of installations in several countries worldwide, we believe there is still massive room for technological advancement and improvement.


StorEn creative efforts focus on increasing power and energy density well above the current state-of-the-art technologies. These efforts resulted in patent-pending innovations developed in fluid dynamics of the stack, electrolyte molarity and battery design.


StorEn batteries deliver a reduction of 50% in the cost of the power side of the battery, an increase of 25% in battery capacity and longer service intervals with improved reliability to exceed a  20-year operative life. We deliver the lowest Total Cost of Ownership (TCOs) possible today.
