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%.
2.3MWp grid connected photovoltaic array on Auckland Airport’s new outlet centre. Auckland Airport’s modern retail outlet centre, Mānawa Bay at opening had the largest rooftop solar system in New Zealand, on top of the 35,000m2 building.
There is about 200 MW of rooftop solar on residential buildings across New Zealand. The rest is commercial and industrial solar installations, where the business uses some or all of the solar generation on site. Any leftover generation is fed into the distribution network for other businesses and households to use.
At 2.3-megawatts, the solar array is expected to generate the equivalent of 80 per cent of the 100-store centre’s power usage. Auckland Airport’s Chief Commercial Officer Mark Thomson said sustainability is a core feature of the purpose-built premium outlet shopping centre.
Flyover of the Manawa Bay Outlet Centre roof-top solar, at Auckland Airport Mānawa Bay, Auckland Airport’s modern retail outlet centre, currently under construction, is set to have the largest rooftop solar system in NZ, at 2.3 megawatts.
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.

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%.
