Wang Changlin, deputy head of the National Development and Reform Commission (NDRC), announced that the free trade port will launch island-wide independent customs operation on December 18, 2025. The proportion of tariff lines with zero-tariff products in Hainan Free Trade Port will increase from 21 percent to 74 percent.
On June 10, 2021, the 29th meeting of the Standing Committee of the 13th National People's Congress passed the Hainan Free Trade Port Law of the People's Republic of China, which determined to establish and improve the Hainan Free Trade Port customs supervision special zone system with closed-off customs operations on the entire island.

[Photo/Xinhua] The Hainan Free Trade Port will launch island-wide independent customs operations on Dec 18, a key step in transforming the tropical island into a globally significant free trade hub, a senior official announced Wednesday.
"With the independent customs operations, Hainan FTP is poised to become a key gateway for China's new era of opening up and innovation," Cai added. China's Hainan Free Trade Port (FTP) is set to launch an island-wide independent customs operation on Dec. 18, 2025, underscoring the country's wider push for high-standard opening up.
Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only. When a carry-on bag is checked at the gate or at planeside, all spare lithium batteries and power banks must be removed from the bag and kept with the passenger in the aircraft cabin.
Lithium-ion batteries, such as power banks, should only be packed in carry-on baggage, according to US FAA and Transportation Security Administration (TSA) rules. In general, most airlines allow each passenger to carry a maximum of two lithium-ion power banks of 100-160 Watt-hour (Wh) into the cabin.
Power banks and batteries are now only allowed in hand luggage, not overhead bins. Passengers are also prohibited to charge their power banks by plugging them to in-seat power supply systems that airlines provide, the report says.
Similarly, passengers are not allowed to recharge the power bank from an aircraft’s USB outlet. Some airlines are requiring passengers to remove their power banks from bags and keep them in a seat pocket. They also advise insulating the terminals to avoid a short circuit. Why are airlines banning power banks now?
In the early 2000s, Germany encouraged people to install solar panels on the roofs of their homes by rewarding them with payments, known as feed-in tariffs, for sending energy to the grid. But those have become less lucrative in recent years, making such large-scale investments less attractive.
But in homes across Germany, they are powering a quiet transformation, bringing the green revolution into the hands of people without requiring them to make a large investment, find an electrician or use heavy tools. “You don’t need to drill or hammer anything,” Ms. Berg said.
History of German feed-in tariffs in ¢/kWh for rooftop solar of less than 10 kW p since 2001. For 2016, it amounted to 12.31 ¢/kWh. Germany introduced its feed-in tariff in 2000 and it later became a model for solar industry policy support in other countries. : 145
Energy storage systems, microgrids. The purpose of this study is to develop an effective control method for a hybrid energy storage system composed by a flow battery for daily energy balancing and a lithium-ion battery to provide peak power.
Hybrid energy storage systems are advanced energy storage solutions that provide a more versatile and efficient approach to managing energy storage and distribution, addressing the varying demands of the power grid more effectively than single-technology systems.
In 11 the energy management system was implemented for a stand-alone hybrid system with two sustainable energy sources: wind, solar, and battery storage. To monitor maximum energy points efficiently, the P&O algorithm was used to control photovoltaic and wind power systems. The battery storage system is organized via PI controller.
The hybrid energy storage configuration scheme is evaluated based on the annual comprehensive cost of the energy storage system (Lei et al. 2023). Based on balance control and dynamic optimisation algorithm, a method is described for hybrid energy storage capacity allocation in multi-energy systems.
For those investing in renewable energy, particularly solar power, the compatibility of solar energy storage cabinets is a key consideration. These systems are designed to store surplus energy generated by solar panels during the day for use when sunlight is unavailable, such as at night or during cloudy periods.
Effective solar energy storage cabinets seamlessly integrate with solar PV inverters and management systems, often featuring sophisticated software to optimize charging and discharging cycles based on generation patterns and household consumption.
A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy.
For systems designed for scalability, look for specific link ports (e.g., Link 1 & Link 0 as seen in products like the I-BOX 48100R) that facilitate enhanced connectivity for multi-unit installations, allowing your energy storage capacity to grow with your needs. Safety is non-negotiable when dealing with electrical systems.
