Kemwatt announces that it has successfully designed, assembled and tested the first 10 kW industrial prototype of an Organic Redox Flow Battery, that can store electricity from renewable sources or support smart grids and micro grids.Based on its innovative chemistry and stack (the energy converter), this very first non-corrosive Organic Redox Flow Battery of industrial size has required two years of development from the French startup. It paves the way to simple, reliable and affordable storage solutions, and represents a major step for the expansion of renewable energy, smart grids and micro grids around the world.

Storing and releasing large amounts of energy in a cleaner way

In spite of advances made against global warming and at a time when renewable energy becomes competitive with fossil fuels and nuclear energy, the development of clean energy is constrained today by the management of its intermittency and the question of storage. Redox Flow Batteries offer a solution since they can store many hours of energy production, such as wind energy at night or solar energy in the middle of the day, chemically in liquid electrolytes. However, until today these batteries used highly acidic, corrosive electrolytes, resulting in reliability, lifetime, safety and environmental issues. Thanks to its non-corrosive, alkaline chemistry and its more natural molecules, Kemwatt’s Organic Redox Flow Battery solves these problems and makes large scale implementation possible, whether for industrial purposes or remote areas.

Boosting large scale development of renewable energy and implementation of micro grids

This technology allows universal implementation of renewable energy: with little maintenance and lifetimes comparable to the wind turbines or solar farms they are connected to, these systems will be integrated in smart-grids in the European Union and the United States, and also in emerging economies where they will help powering micro grids. “Our ambition is to accelerate the development and the adoption of renewable energy around the world” explains François Huber, the CEO of Kemwatt. “Our systems will power micro-grids in rural areas in the whole world and bring a modern and clean energy solution to over a billion people who have no access to electricity.” In the coming months, Kemwatt’s technology will be tested in various applications in partnership with customers, in order to finalize product development and quickly initiate sales. A fundraising round will be made early 2017 to carry out these key steps.
