The demand for energy storage in the Netherlands is showing an explosive growth trend, mainly due to the increasingly prominent problems of grid congestion and uneven load, as well as the strong support of government policies and the pressure on the grid brought about by the increasing proportion of renewable energy. Last October, the Dutch Energy Storage Industry Association (Energy Storage NL) announced that the amount of large-scale energy storage used for energy storage and supplying power to the grid in the Netherlands would experience rapid growth after a slow initial development phase, and battery capacity would also increase exponentially.

According to publicly available information, large-scale energy storage projects in the Netherlands are continuously being implemented. With the rise of renewable energy, the battery capacity of energy storage cabinets continues to increase. Currently, nearly half of the electricity in the Netherlands comes from renewable energy sources such as wind or solar power. However, this type of energy is greatly affected by weather factors and cannot fully synchronize with electricity demand. Therefore, there is an urgent need for a certain amount of space to store excess energy for use in case of power supply shortage.

In September 2025, Sungreen Logistics undertook a project for S customer to combine 10HQ energy storage cabinets into 20HQ energy storage cabinets and export them in bulk to the Netherlands, providing full logistics services under DDP terms. This seemingly simple shipping task is actually a comprehensive test of scheme design, domestic operations, and international collaboration.

Technical difficulties and targeted solutions

The core difficulty of this shipment is to combine each independent 10HQ energy storage cabinet into a standard 20HQ energy storage cabinet through dedicated connectors for transportation. It should be noted that the conventional weight of 10HQ energy storage cabinets currently shipped to overseas markets is between 10-23 tons. Although this design can maximize the utilization of container capacity and improve loading economy, it also brings multiple complex challenges.

Firstly, if the combined cabinet is overweight, it is necessary to ensure absolute balance of load-bearing capacity and eliminate the risk of unbalanced loading, otherwise it may cause serious transportation safety accidents. Secondly, the strength and certification of the connectors are crucial, and they must be certified by authoritative institutions, with a tensile index that meets strict standards. Thirdly, shipping companies have extremely strict loading audits for such overweight containers. To avoid the risk of refusal to load, it is necessary to declare the detailed cargo information to the shipping company in advance and clarify the loading requirements. Fourthly, after combining two containers, only one container number should be declared, and the information needs to be synchronized with the shipping agent and terminal system in advance to avoid discrepancies in the documents. Any negligence in any link may result in cabin refusal, high surcharges, and even transportation safety accidents.

The cornerstone of seamless collaboration between transportation and warehousing

The smooth implementation of the project relies on solid and seamless collaboration between domestic transportation and warehousing. This is the starting point of the entire logistics chain and also the first hurdle in controlling risks and ensuring timeliness.

In the transportation process, efficiency is undoubtedly the foundation, but safety and compliance are the primary principles. The person in charge of the Ministry of Transport frankly stated, "Ensuring safe transportation and route compliance is of utmost importance for every energy storage cabinet transportation

If the weight of a single container exceeds 35 tons after linking to 20HQ, domestic road transportation must apply for an over limit certificate and strictly follow the approved fixed route without any carelessness. From dispatching trailers to pick up goods from the factory, to safely transporting them to the self operated warehouse for container dropping, and then executing port entry according to the shipping schedule, the transportation and warehousing teams work closely and seamlessly together. After completing the loading process, the escort personnel will immediately post dangerous goods labels and take photos for archiving, ensuring that every step complies with regulations and achieving full visibility and controllability throughout the process.

Whenever an energy storage cabinet is put into the warehouse, we must put in a lot of effort. Warehouse storage is a crucial part of logistics and directly affects the smooth operation of all subsequent processes, "emphasized the warehouse manager. When receiving the task of storing energy cabinets, the warehouse will confirm the arrival plan with the operating department in advance and reserve a dedicated storage area. After the energy storage cabinet enters the site, the warehouse staff will first check the warehouse receipt, carefully verify the box number, inspect the condition of the cabinet, confirm that there are no errors, and then synchronize the information into the system.

Compliance is the bottom line of warehouse management, and the stacking height of energy storage cabinets must strictly comply with safety regulations of no more than two layers. More importantly, in order to cope with shipping risks, especially to prevent seawater salt spray and rainwater erosion, the warehouse can provide professional customized waterproof raincloth services. Pre fabricate rain cloth according to the cabinet size, and the energy storage cabinet can be quickly covered after entering the warehouse. The reserved inspection window not only provides basic protection, but also facilitates subsequent customs inspections.

The warehouse manager added, "We strictly maintain the energy storage cabinet according to the standards until it enters the port. Every detail is related to the success of the entire project, and there should be no slack

End to end delivery that connects Europe and Asia

This batch of energy storage cabinets was shipped from Yangshan Port in Shanghai at the end of September and arrived at the European gateway port of Rotterdam in early November. Prior to the vessel's arrival at the port, the Sungreen Logistics Netherlands team had already initiated the process of obtaining over limit road permits and pre clearance procedures. It is this mode of parallel operation both domestically and internationally that enables the energy storage cabinet to quickly complete customs clearance upon arrival and be immediately connected by a professional fleet. According to customer requirements, the goods were delivered to multiple project sites within the Netherlands, achieving seamless end-to-end delivery from the Chinese factory workshop to the Dutch project site.

The smooth delivery of this project not only validates the scientific nature of the initial full chain solution, but also relies on strong end-to-end resource integration capabilities and a controllable overseas service network. It has been proven that the comprehensive solution capabilities required by logistics service providers should run through every link from the initial technical solution design, to strict warehousing management and over limit transportation execution in the domestic segment, to international shipping and destination customs clearance and distribution. Each link requires a deep integration of professional knowledge and practical experience.

As a full chain logistics provider, Sungreen Logistics has the ability to intervene in the product design phase of energy storage cabinet enterprises and provide professional logistics advice. This can not only lay a solid foundation for the smooth export of energy storage cabinets, but also rely on international logistics transportation solutions to customize and meet the full cycle and full chain service needs of overseas project delivery, providing strong support for the international development of the energy storage industry.
