Battery and technology

Barges have a capacity varying from 500 to 1000 kW. With a ZESpack of 2600 kWh, a barge can sail for 2 to 6 hours; with 2 ZESpacks on board, it can travel a distance of 60 to 120 km. And there’s Zero Emission: the battery containers are charged with green energy, and the barge’s electrical powertrain ensures that no CO2, nitrogen or particulate matter is emitted. In addition, a ZES ship makes hardly any noise. 

100% safe

Control systems in the container and on board ensure batteries cannot be overloaded. Cooling systems keep the temperature inside the container constant. The container itself is fire-safe thanks to insulation and the fact that it is equipped with fire extinguishing and safety systems. Even in the case of an external fire, the container remains safe!

Watch the explanation of the fire protection system of the ZESpack given below.

Environment and materials

The ZESPack for this application is guaranteed to last 10 years. After 10 years, the capacity of the batteries is reduced by about 20 %. Use of the ZESPack for another 10 years is possible in numerous other applications. At the end of the lifespan, the materials can be recovered and made suitable for reuse. Due to the long service life of the ZESPack, the system saves far more in emissions than it costs to build the batteries.

Multiple applications

Whenever the battery containers are not on board a barge, they can be used to stabilise the electricity grid. Grid stabilisation, the balance between supply and demand, is essential to make the electricity grid reliable. In the future, the electricity supply will fluctuate more as we draw more on solar panels and windmills and less on power plants. Monitoring the grid stability will then come to depend more often on smaller components, like batteries, boilers and heat pumps. ZESpacks can also be employed to meet a temporary demand for electricity: for example, to power an event or a building site, or to provide vessels with shoreside power.

Future-proof system

The system is future-proof because it is independent of an energy carrier. We will start out using batteries, but if hydrogen becomes cheaper in the future, hydrogen technology-equipped containers with will be able to supply power in the same way. The charging stations are designed to allow for synergies with other technologies, such as hydrogen.
