Driven by energy transition and carbon neutrality, Europe is accelerating the construction of its green energy system, and the demand for energy storage market is showing explosive growth. With the continuous encouragement of policies and subsidy measures in various countries, large-scale energy storage projects have been implemented one after another. As a core country in the global research and manufacturing of energy storage equipment, China's export of energy storage cabinets to Europe continues to rise, with high-capacity and ultra standard containerized energy storage systems becoming the main force in going global. However, opportunities and challenges coexist, and how to safely, efficiently, and economically transport large quantities, overweight, and oversized energy storage cabinets to project sites has become an urgent logistics challenge for many enterprises.

During the National Day holiday in 2025, Sungreen Logistics successfully shipped 40 5MWH 20HQ overweight energy storage containers from T company, departing from Yangshan Port in Shanghai, transiting through the transfer port, and finally arriving at Lisbon Port in Portugal, where on-site delivery was completed. This project is undoubtedly an extreme stress test of Shunxin's logistics resource integration ability, professional operation level, and emergency response capability.

The difficulties faced in this mission were unprecedented, like an extreme challenge racing against time under multiple constraints, "recalled the project leader of Sungreen Logistics.

The challenges come from various aspects. Firstly, there is a shortage of cabin resources. During the National Day holiday, shipping companies have suspended a large number of flights and there are frequent empty flights, and there are no container ships directly to Lisbon. The available transshipment ships not only have unstable schedules, but most ships have strict restrictions on the loading of dangerous goods and overweight containers, which undoubtedly increases the difficulty of booking.

Secondly, international transit connections are complex, and goods need to be transshipped at the transit port. The window period for connecting the first and second ships is extremely short, and the connection must be completed within 5 days. At the same time, the unloading and temporary storage processes at the transit port require precise coordination, and any delay may result in the entire process being disconnected.

Thirdly, the domestic operation process has been compressed during holidays, and the window period for domestic booking, customs declaration, maritime declaration and other links has been compressed due to holidays. All operations must be pre planned and efficiently promoted, with extremely low fault tolerance.

The fourth challenge is the arduous task of final delivery. Before the arrival of 40 overweight energy storage cabinets in Lisbon, the local team needs to coordinate the heavy shore crane operation, conduct a full survey and risk control of the transportation route, and handle the permit for oversized vehicles in advance. After customs clearance, it is necessary to arrange a qualified professional low board truck fleet for bulk delivery to the project site.

Faced with these challenges, Sungreen Logistics resolutely took on this task, relying on a forward-looking full chain planning scheme and strong end-to-end resource integration capabilities to develop a comprehensive breakthrough plan.

Sungreen Logistics, relying on its core advantage as a first tier booking agent for shipping companies, quickly coordinated and locked in cabins for the same shipping company and voyage, ensuring that all goods could be shipped on the same ship at once, fundamentally avoiding delays and additional costs that may arise from batch transportation, laying a solid foundation for the smooth progress of the project. The operation team completed all customs declaration and maritime filing in advance, and adopted the "vehicle and vessel direct loading" mode. After arriving at the port, it was directly hoisted onto the ship, saving storage costs and secondary handling risks.

The selected transshipment port for this transportation ranks among the top in global port performance rankings, renowned for its excellent operational efficiency and professional loading and unloading facilities. Sungreen Logistics, through close collaboration with ports and shipping companies, has planned transit routes in advance to ensure rapid unloading and temporary storage of goods upon arrival at the port. Within 5 days, they have successfully connected to a second leg ship and sailed towards the final destination of Lisbon Port.

As early as the goods were shipped out, the Portuguese local team had already intervened and conducted a systematic transportation risk assessment, quickly submitted materials to apply for an oversized vehicle permit, and planned the optimal delivery route. After 40 energy storage cabinets arrived at the port and completed customs clearance, the team immediately coordinated large lifting and unloading equipment with qualified low plate fleets to complete unloading and bulk delivery, directly reaching the project site, achieving seamless connection from the port to the project site.

This not only tests the integrity of the plan itself, but also highly relies on efficient collaboration between domestic and foreign teams and deep cultivation of the entire logistics chain, "said the project leader of Sungreen Logistics.

From domestic factories to overseas project delivery, this is not just a simple transportation process, but also a perfect combination of developing a complete plan and efficient collaboration between domestic and foreign teams. Sungreen Logistics has built a truly end-to-end delivery capability with its first-class agency status, self operated dangerous goods warehouses, professional low board fleet, as well as overseas branches and agency systems covering major economic regions around the world. This comprehensive layout enables Sungreen Logistics to provide professional and reliable services for every link in the complex logistics chain of energy storage going global.

The more critical combination of "talent+risk warning" is the team's ability to integrate massive fragmented information such as EU regulations, dynamic policies of shipping companies, and port operation rules, and transform it into a dynamic risk assessment model and visualized full chain management. This ensures that even in the most complex market environment, stable and reliable supply chain solutions can still be provided to customers.
