ZES (Zero Emission Services) provides exchangeable energy containers for new and existing inland barges. These containers – ZESpacks – are charged with green electricity. Once depleted, the skippers can quickly exchange the containers for a fully charged one at one of the exchange and charging stations. These stations form part of an “open access” network; they can be used to stabilise the electricity grid or to supply a temporary local demand for electricity. ZES offers users a future-proof solution. The ZESpacks could work with hydrogen in the future, for example. With this concept, ZES offers its various stakeholders a concrete, ready-to-use solution to improve sustainability.
