Company History

Named after Eos, the Greek Goddess of the Dawn, Eos Energy Storage aims to bring about a new dawn of energy storage—one that will transform the way we produce, deliver, and consume electricity.

Eos’ mission is to develop cost effective energy storage solutions that are not only less expensive than other battery technologies, but less expensive than the most economical alternative used today to provide the same services – a gas turbine for peak power generation and transmission and distribution assets for delivery capacity. Eos views energy storage as a solution to real business problems, and is developing a battery technology that responds directly to the requirements of the business case at hand. The result is Eos’ novel, proprietary Znyth® technology—the first low-cost, long-life, inherently safe, energy dense, and highly efficient aqueous battery.

Founded in 2008 after the issuance of the patent for its core technology, Eos has grown to become a leader in the nascent and rapidly growing energy storage industry. Eos’ elite research and development team is led by management with decades of experience in battery technology and building successful energy companies.

Eos has established a strong commercial platform, partnering with leading suppliers, manufacturers, and utilities to enhance and accelerate product development.

Join Eos as we work towards building a more efficient, cleaner, and more secure energy future for America and the world.


Michael Oster

Chief Executive Officer

Michael OsterMichael’s experience includes real estate, emerging markets, technology and renewable energy. Prior to Eos, Michael launched Clean Energy Holdings as a vehicle to develop solar power and invest in energy technologies. He had developed several of the larger commercial solar power systems in New Jersey in partnership with a major European utility. Michael co-founded Eos with Steve Amendola and was the first investor in the company. Michael began his career in strategy and business planning based at IBM’s largest development and testing facility, and he later joined the international management consulting firm of A. T. Kearney. In 1991, Michael moved to Russia as privatization was starting and built what was one of the first and largest real estate investment and development companies in Moscow and St. Petersburg. In 1994, Michael established the first institutional real estate investment fund in Russia in partnership with the AT&T pension fund, and developed numerous successful projects. In the last decade, Michael formed and capitalized an early stage technology venture capital firm in New York City. He was one of the original partners to launch the global energy technology firm Aspect Enterprise Solutions together with Steve Hellman, where he populated the board and investor group with OPEC oil ministers, US cabinet members and other energy industry leaders. Michael has been quoted or profiled in the Wall Street Journal, the New York Times, USA Today, the London Observer, the Moscow Times and other publications. Michael received his BA from Brandeis University and his MBA from NYU where he won an award for best thesis for his work on evaluating risk. He speaks Russian and French.

Steve Hellman


Steve HellmanSteve Hellman joined Eos as Director after a long career of building new companies, largely in energy and real estate. Steve began his energy career with Glencore, the largest commodities trading company in the world, where he built six successful companies in oil production and refining. Thereafter he created his own energy trading company which grew to $8B in revenues, and built a shipping company of 27 tankers. Together with Michael Oster he later created Aspect Enterprise Solutions, an energy technology company which provides software as a service to hundreds of major oil and energy companies (clients include BP, China Oil, ExxonMobil and Gazprom). In recent years he acted as an Advisor to the US State Department where he worked with Heads of State and Senior Ministers throughout Eurasia to resolve energy conflicts and to develop a strategy for Eurasian oil and gas infrastructure development. Steve also independently built a $150M commercial real estate business. Steve speaks Russian and Chinese, is a member of the Council on Foreign Relations, and holds an MA (Industrial Engineering) and a BS (Political Science, Slavic Languages) from Stanford University (Phi Beta Kappa, 1987).

Steven Amendola


Steven AmendolaSteve invented and patented Eos’ battery technology and co-founded the company Eos Energy Storage. Steve is also the inventor and founder of Renewable Silicon International (RSi), a silicon processing technology that reduces silicon costs by more than 60% compared to the industry standard silicon processing methods. RSi has been funded by the Quercus Trust and has started manufacturing at its plant in Easton, PA. Steve also founded the company Millennium Cell, which developed a very high energy density battery/fuel cell technology. Steve managed the company (which grew to 50 employees and later went public) before leaving to develop new technologies in 2002. Steve has been awarded more than two dozen U.S. patents, with approximately 20 additional patents pending and many corresponding foreign patents related to new fuels, turbines, diesel fuels, and hydrogen production. Steve’s area of specialty is large scale power storage. He has a deep knowledge and decades of experience evaluating and developing related technologies.
