S4 Energy’s Post

We are looking for an ambitious Strategic Assistant to support our executive team with a blend of administrative tasks, strategic planning, and HR functions. Do you have excellent organizational and analytical skills and want to contribute to our company's growth? Apply now and join our dynamic team at S4 Energy

Please join the team!

It was a pleasure to show Chantal Zeegers our solution that contributes to CO2 savings in the port area. We also managed it without enlarging the electrical grid connection at Stedin! Glad to provide a tangible solution for Netbeheer Nederland to help tackle the grid congestion. Thank you WAALHAVEN GROUP and Gemeente Rotterdam for supporting us.

As of January 1st, 2024, S4 Energy welcomes two experienced professionals to its executive team. Bob Bouhuijs and Femke de Vries will assume the roles of CEO and CFO, respectively.  Together with Dominique Becker Hoff, CCO, they form the complete management team of S4 Energy, poised to expand the installed energy storage capacity—a critical component for grid stabilization in the context of the energy transition.

S4 Energy has signed a contract with Tesla for the delivery of 12 Megapacks. This marks a significant step for S4 Energy in the development of large-scale energy storage systems aimed at further stabilizing the Dutch electricity grid.   Dominique Becker Hoff, CCO of S4 Energy, expressed delight at this milestone: "We have been working closely with Tesla Energy recently to bring this first project to realization. We're very pleased with the synergy our teams have realized and eagerly anticipate further collaboration in building our significant pipeline of upcoming energy storage projects.”   The initial 12 Megapacks will be deployed in a hybrid energy storage installation, consisting of batteries and KINEXT flywheels. This installation intelligently combines the advantages of both storage media and will be used to provide services to the operator of the national high-voltage grid, TenneT, and to the regional grid operator, Stedin. The installation has a capacity of 11 megawatts (“MW”) and 44 megawatt-hours (“MWh”), meaning it can release electricity at its peak power for four hours.   S4 Energy looks forward to continuing to build upon this initial Tesla Megapack order with future large-scale energy storage projects in the Netherlands and other European countries, developed and implemented in collaboration between S4 Energy and Tesla.

S4 Energy's KINEXT flywheel is now operational at the United Waalhaven Terminals to support the harbor crane. The crane now operates fully electrical, without the need for an upgrade of the grid connection. KINEXT shaves the peaks in power demand from the crane and stores the braking energy. This new application of the KINEXT flywheel was supported by the Smart Energy Systems program of the city of Rotterdam. https://bit.ly/48Y8sYe

With the implementation of KINEXT, the flywheel-based energy storage system developed by S4 Energy, the Kone Gottwald port crane at United Waalhaven Terminals (UWT) in Rotterdam is now fully electrically powered. The diesel generator that powered the crane in previous years has been turned off, resulting in both fuel savings and an immediate annual reduction of 500 tons of CO2 emissions. KINEXT allows the crane to operate entirely on electric power. The kinetic energy released when lowering a load is stored in the flywheel. When a load needs to be lifted, the flywheel provides the stored energy to meet the crane's peak power requirements. This combination maintains a constant and low power consumption from the grid, eliminating the need for investing in a larger grid connection. This innovative application of the KINEXT energy storage system is supported by the Smart Energy Systems program of the city of Rotterdam.
