About S4 Energy

S4 Energy employs specialist expertise and equipment together with sophisticated software to fully unlock the power of energy storage. We help energy producers, grid operators and end users to stabilize supply and demand and make the most of their existing infrastructure and energy flows. Our mission is to make our client’s energy and power management smarter, more flexible and more profitable.

Our solutions consist of a range of storage techniques (chemical, electrolytic, kinetic) and incorporate proven technology both from partners and our own portfolio. S4 Energy has developed and holds various patents on energy storage technologies, including our uniquely efficient KINEXT storage units.

S4 Energy is based in the Netherlands and was founded by a group of former corporate executives and informal investors. Our team has extensive international experience up to an executive level in engineering, consultancy, finance, science and manufacturing.
