Big changes are underway in Hainan—and they’re designed to make everyday life smoother for residents, expats, and businesses alike. China's Hainan Free Trade Port will officially launch island-wide independent customs operation on December 18, 2025, completing its transition into a full-fledged Free Trade Port.
In April 2018, China announced plans to transform the island into a pilot free trade zone, with a long-term vision of developing a free trade port with Chinese characteristics. A master plan released in 2020 aimed to make Hainan a globally influential hub for high-level openness by mid-century.
Wang Yang publishes an official definition of a free port in the People’s Daily. Announcement of a free trade zone covering the entire island of Hainan during the 30th anniversary of the Special Economic Zone. Launch of the Master Plan for the construction of the Hainan Free Port, aiming for global status by 2050.
The "Notice on Preferential Corporate Income Tax Policies for Hainan Free Trade Port" proposed that enterprises in encouraged industries registered and operated in Hainan Free Trade Port shall be subject to a reduced corporate income tax rate of 15%.
Sigenergy offers home battery storage, residential ESS, and commercial solar solutions. Explore our innovative energy storage systems for sustainable power management.
These top energy storage companies 2023 are among many global leaders providing energy storage solutions: Fluence was established by Siemens and AES, both industry powerhouses in energy storage. Fluence’s energy storage systems are designed for common use cases and are also customizable for more specific applications.
Most of the world's grid energy storage by capacity is in the form of pumped-storage hydroelectricity, which is covered in List of pumped-storage hydroelectric power stations. This article list plants using all other forms of energy storage.
The city of Fresno, California has flywheel storage power plants built by Amber Kinetics to store solar energy. There is a 110 MW compressed air facility in McIntosh, Alabama and a 290 MW compressed air facility in Huntorf, Germany. 3. Battery Storage
Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants. In: Proceedings of ASME Turbo Expo 2004: Power for Land, Sea, and Air; 2004 Jun 14–17; Vienna, Austria. ASME; 2004. p. 103–10. F. He, Y. Xu, X. Zhang, C. Liu, H. Chen
A study numerically simulated an adiabatic compressed air energy storage system using packed bed thermal energy storage. The efficiency of the simulated system under continuous operation was calculated to be between 70.5% and 71%.
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.
Battery energy storage capacity is the total amount of energy the battery can store, measured in kilowatt-hours (kWh) or megawatt-hours (MWh). Think of this as like the size of a water tank where you measure the water capacity in litres.
Battery storage duration describes how long the battery can discharge at its rated power. It’s calculated: Energy Capacity (MWh) ÷ Power Rating (MW). A 4 MWh battery with a 1 MW power rating has a 4-hour duration. A 1 MWh battery with a 2 MW power rating has a 0.5-hour duration. We’ve written about storage duration in more detail here.
Battery capacity is a core indicator of battery performance, representing the total amount of energy a battery can release under specific conditions, such as discharge rate, ambient temperature, and cutoff voltage. Battery capacity is usually expressed in three units: Ah (Ampere-hour), Wh (Watt-hour), and kWh (Kilowatt-hour):
Nauru Telikom (Neotel) has launched 5G in Nauru, which it claims to be Oceania's first nationwide 5G+ network service. The carrier launched the network earlier this week. In the announcement earlier this week, the carrier noted that the launch of 5G will spur job opportunities across various sectors including telecommunications and IT.
