Bringing battery storage into the 21st century

Incubated at the Clean Energy Business Incubator Program (CEBIP) within Stony Brook University in New York, StorEn delivers proprietary vanadium flow batteries to revolutionize the world of industrial energy storage. 

This technology brings superior performance at a lower cost, providing more efficient, safe, environmentally friendly and cost-effective energy storage. StorEn takes what vanadium batteries already deliver - durability and sturdiness - and through extensive R&D has enhanced the electrical efficiency of the stack and the energy density of the electrolyte and module, ultimately reducing costs. Our research has led to four international PCT patents and five trademarks to date. 

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

The Problem

Other batteries just don't get the job done

Unlike Lithium and Lead Acid Batteries, StorEn Vanadium flow batteries are:

  • Eco-Friendly: 100% recyclable, 100% reusable electrolyte, low GHGs emissions, non-pollutant, and reduce mining!
  • Safe: Non-flammable, non-explosive

  • Cost Effective: Cost/kWh comparable to lithium batteries but Cost/Cycle up to four times lower than lithium batteries, thanks to the exceptional duration of 25 years or 15,000K cycles

  • Efficient: +35% in energy storage with the same volume, +5% Round-Trip efficiency in harsh climate

The Solution

A greener solution that outperforms the competition

A StorEn battery module will work in synergy with the solar system. During the day, your solar panels will capture energy from the sun. This energy then charges the battery while simultaneously powering a home or office. Then, as day turns to night, the battery takes over, providing green energy consistently, and maximizing your solar system dependability.


In addition to its solar storage capabilities, the StorEn battery, in locations with dual rates, can store power from the grid at night when electricity prices are low. By using battery power during peak electricity times, clients can lower their utility bills. Our customers can safeguard the environment while saving money! Additionally, in the event of an emergency, the StorEn battery guarantees continuity to your home and vital devices such as telecommunication, lighting, refrigeration, and heating and ventilation systems. Finally, StorEn delivers additional resilience in case of a natural disaster.

Our Industrial Microgrid Solution

StorEn Technologies is developing a containerized energy storage system that will be offered to the utility and telecommunications industry. We have partnered with Connexus Energy, a Rural Electric Cooperative to build a system that will be placed at their headquarters in Ramsey, Minnesota. This system will supply 20kw of power and 100kwh of energy (5 hours run time) and will be used to demonstrate how our system can complement medium to large scale energy storage solutions in various utility applications. StorEn Technologies was selected for this project after a rigorous validation process by Connexus and by GridCatalyst, a clean energy accelerator program focused on the midwest region of the United States. 

Our first system is scheduled for deployment in early 2023. The successful deployment of this first system will open up our market opportunities across the country to hundreds of small to medium size utility companies looking for stationary energy storage solutions. StorEn Technologies is currently building the cell stacks needed for this project and we have teamed up with a reputable contract engineering and manufacturing company to build the containerized system for this deployment.   

Our batteries are modular. Our customers will only pay for the energy capacity they really need! Additional modules can be connected together for maximum flexibility!

The Market

The solar market is booming!

The trend for wind energy in the US is as bullish as solar. Historic private sector investments are expected to expand the wind energy supply chain. In 2021 alone, investors announced $2.2 billion in new funding, including commitments to develop nine major manufacturing facilities to produce the foundations, towers, cables, and blades of offshore wind turbines (source). Supplier contracts to provide materials and services to offshore wind projects more than doubled. More opportunities are ahead, including an estimated $109 billion revenue opportunity across the offshore wind supply chain this decade. Nearly 40 GW of offshore wind is already procured, providing a strong demand for clean energy that will lower energy costs for American families while protecting them from volatile fossil fuel price spikes (source). 

The Solar Energy Industries Association’s goal of having solar account for 30% of electricity by 2030 will provide an even greater boost to accelerate the deployment of solar energy (source).

For long duration storage applications in excess of 2 hours, such as offshore wind, lithium batteries are not cost effective. Vanadium flow batteries are the ideal choice!

  • Founding Team's 3rd energy start-up 

Winner of numerous Technology and Innovation awards 

With the partners who can make it happen

And exclusive rights to high-end supply-chain partner

StorEn has entered into a supply chain deal with Multicom Resources, an Australian mining company which is the owner of two vanadium mines. Through this exciting arrangement, StorEn has secured the exclusive availability of vanadium for up to 20 years with either a price cap or at market price, whichever is the lowest.

Capitalizing on the governments’ support to fulfill the Australian energy storage opportunity, Multicom’s subsidiary, Freedom Energy, will assemble StorEn batteries within Australia and distribute them widely across the wider Asia Pacific region. In addition to an initial pilot plant, Multicom has completed a concept design for a full-scale manufacturing facility for StorEn batteries.

What We Do

Bringing power to the home

Our batteries charge using electricity generated from solar panels. When the sun goes down, our batteries use the solar energy accumulated throughout the day to power the home through the evening and night. Home batteries also recharge when electricity rates are low, and use that energy later, when rates are higher. Our home battery will be cost-effective, easy to install and environmentally-friendly, offering an energy addition to a solar system and the utility grid.

StorEn is a member and supports the mission of advancing zero-energy green buildings and LEED.
A Solution for Developing Economies

Over a billion people still do not have access to electricity. Living without electricity has a major impact on daily activities such as cooking and food preservation as well as key development indicators such as access to health, access to education and economic development. The electrification of these unserved communities can become a reality with mini grids, using solar plus energy storage. StorEn’s vanadium flow batteries can be a key technology towards universal access to affordable, longer-lasting and dependable energy.

To support this critical mission, Storen Technologies is proud to be a member of the Alliance for Rural Electrification and the Global Off-Grid Lighting Association.

The Business Model

Tax credits make residential storage even more appealing

Battery systems that are charged by a renewable energy system more than 75% of the time are eligible for the Investment Tax Credit (ITC). Battery systems that are charged by a renewable energy system 75%–99.9% of the time are eligible for that portion of the value of the ITC. 

In addition to the federal Investment Tax Credit, additional State credits may reduce the cost of an energy storage system.  For example, a system charged by renewable energy 80% of the time is eligible for the 30% ITC multiplied by 80%, which equals a 24% ITC instead of 30% (the tax credit is vested over 5 years, and recapture can apply in unvested years if the percentage of renewable energy charging declines).

Although energy storage is a relatively young industry, a growing number of states and municipalities will support the installation of solar-powered batteries to accelerate the transition to renewables and the reduction of GHG emissions. Maryland established a solar battery tax credit worth 30% of the total installed system cost, up to $75,000 for commercial systems. While in California, a cash rebate is available through the Self-Generation Incentive Program (SGIP).

Why Invest

A Note from StorEn's CEO

To Our Prospective Investors,

It is an exciting time at StorEn! Last year, we completed our THIRD successful Regulation Crowdfunding campaign on StartEngine, maxing out our old StartEngine raises from hundreds of investors that share our passion for technology and the environment. Our investors contribute to companies with a higher cause. 

The funds raised allowed us to hit several additional milestones,  advancing our development! We were able to use these funds to design and test our cell stack technology, the heart of our flow battery system. We also brought on new engineering talent at our facility in Italy and we are working to expand our team here in the United States. I would like to thank our community for the additional support and those who invested in StorEn in our fundraising campaigns. 

Following the successful independent validation of our prototype installed at the Advanced Energy Center at Stony Brook University in 2019  performed by the New York State Pollution Prevention Institute (NYSP2I) in Rochester in NYS, we commenced our early manufacturing phase. In January 2020, we delivered our first battery to Australia. The first one of an order worth up to $500,000. 

In 2020, following an Award from the Empire State Development's Division of Science, Technology and Innovation (NYSTAR), we started an R&D program with Cornell University on innovative components. This work, in addition to the ongoing NYSERDA-funded R&D program with Rensselaer Polytechnic Institute and University of Illinois in Chicago, allows us to explore technological improvements that will be the foundation of our future generations of our batteries.


With the funds raised, we also entered the National Phase of the PCT (WIPO in Geneva, Switzerland) process. Thus, we selectively and successfully extended our four patents in several regions and countries, including the USA, European Union, South Africa, Brazil, Israel, Japan, India, China, Australia, Korea, Indonesia and many others, covering approximately 90% of the world population.

In April of this year, we were selected to build a containerized microgrid system to be demonstrated in a live network at the headquarters of Connexus Energy, located in Ramsey, Minnesota. This system involves having four of our current cell stacks working in tandem with each other and will help us understand the performance of our systems in a live environment. Our systems must operate in all types of climates and conditions. The winter conditions in Minnesota will challenge our system and will supply excellent data for our engineering teams to design an extremely reliable system.  

We are now asking our community and those who would like to join us, to support us in the next phase of our journey, our Reg CF offering. 

Please help us build a successful business while sharing a superior cause: The love for our planet! Our vanadium batteries can enable the transition to electricity generated from renewable sources, like the sun and the wind, and we envision that one day our batteries will work in tandem with solar generation in an environmentally-friendly, safe and cost effective manner. 

In addition to this goal, we rest assured that our batteries in conjunction with solar panels can be the ideal technical solution to bring electrification to off-grid communities, such as the ones in developing countries, to eradicate poverty and to promote economic development! 

Together we can make StorEn a success while accomplishing our incredible mission. 

Help us to do well while doing good! Support StorEn! 

Sincerely yours,

John Davis, CEO
