Houston Energy Advisors

ESS Inc. provides safe, environmentally sustainable, energy storage technologies and services that are transforming the industry and accelerating the adoption of renewable energy globally. ESS Inc. has partnered with Munich RE to launch industry-first insurance coverage of its flow batteries. The innovative policy means our long-duration storage solutions are now backed by a full 10-year performance guarantee, regardless of project size or location. Energy storage demand is growing significantly.

At ESS Inc., our mission is to bring to market the cleanest, lowest-cost long-duration energy storage systems. We are the catalyst for a sustainable energy future. Established in 2011, ESS Inc. manufactures low-cost, long-duration iron flow batteries for commercial and utility-scale energy storage applications requiring 6+ hours of flexible energy capacity. Our long-duration energy storage platforms, the Energy Warehouse™ (EW) and Energy Center™(EC), use iron, salt, and water for the electrolyte, and deliver an environmentally safe, long-life energy storage solution for the world's renewable energy infrastructure.

At ESS Inc., we're encouraged by the increased amount of renewable energy penetration across the grid. We know that, with wind and solar energy storage deployments growing up to 46% year-over-year, electric utilities need alternatives to lithium-ion that are clean, resilient and have long operating lifetimes and are not cycle limited. Our iron flow battery solutions, the Energy Warehouse™ (EW) and Energy Center™(EC) offer more than double the operating lifetime and cycle capacity of lithium-ion battery storage systems, with a non-flammable chemistry and minimal maintenance requirements.

Many remote locations are forced to rely on power from diesel generators which comes with significant cost, maintenance requirements, noise and negative environmental impact. Microgrids can help communities become energy independent and in many cases more environmentally friendly. Renewables plus energy storage can act as the baseload power source of a microgrid and reduce the use of costly fuel generators. As more remote locations move toward renewable energy adoption, our EW™ becomes an ideal solution for renewables integration with minimal environmental impact.

Energy is a significant operating expense that needs to be minimized to improve a company's bottom line. At ESS Inc., we believe that proactively addressing this in a sustainable way is just smart business. If you're looking to utilize renewable energy to support your brand and lower costs, long-duration energy storage may be the solution for you. Whether it is managing the self-supply of intermittent solar or wind energy, maximizing savings from existing utility tariffs for demand charges and time-of-use rates, or protecting your facility's energy security from grid outages, an economical, long-duration energy storage solution can give you control of your distributed energy resources.
