HOME / inside china s hainan free trade port what changes in 2025
The creation of a free trade port is the highest level of opening-up in the world today. With rich natural resources and the advantages of being backed by China's mega-market, the Hainan FTP covers the entirety of the 33,900-square-kilometer Hainan Island. The FTP currently has eight open ports and 10 second-line customs ports.
On December 18, the country launched island-wide special customs operations in Hainan, transforming the entire island into a high-standard free trade zone, encompassing not a single port or industrial park, but the whole island.
The island-wide special customs operations in Hainan FTP, that began from Dec 18, are different from how the rest of China's general territory functions. Trade in Hainan operates through a dual-line system: the first line between Hainan and overseas markets, and the second between Hainan and China's mainland.
The FTP currently has eight open ports and 10 second-line customs ports. China aims to build the Hainan FTP into an important gateway that leads the country's opening-up in the new era.

In total, the cost of a 2MW battery storage system can range from approximately $1 million to $1.5 million or more, depending on the factors mentioned above. It is important to note that these are only rough estimates, and the actual cost can vary depending on the specific requirements and characteristics of each project.
On average, the cost of lithium-ion battery cells can range from $0.3 to $0.5 per watt-hour. For a 2MW (2,000 kilowatts) battery storage system, if we assume an average battery cell cost of $0.4 per watt-hour, the cost of the battery alone would be 2,000,000 * $0.4 = $800,000.

The LM-complementarity between wind and solar power is superior to that between wind or solar power generated in different regions. The hourly load demand can be effectively met by the LM-complementarity between wind and solar power.
Based on the China Surface Climate Data Dataset V3.0, we analyze herein the spatial and temporal distribution in wind- and solar-energy resources in China and evaluate via the Spearman coefficient the temporal complementarity of wind- and solar-energy resources in China.
Intra-seasonal complementarity of wind and solar energy across China under the baseline and climate change scenarios. In contrast, Tibet shows extremely strong inter-seasonal complementarity but high intra-seasonal similarity (except winter), meaning that wind and solar resources tend to vary in the same direction.
The results reveal that wind energy and solar energy resources in China undergo large interannual fluctuations and show significant spatial heterogeneity. At the same time, according to the complementarity of wind and solar resources, over half of China's regions are suitable for the complementary development of resources.
