On November 20, 2022, the first foreign-invested enterprise cluster in Hainan Free Trade Port serving foreign-invested enterprises was unveiled in Qiongshan District, Haikou, and six foreign-invested enterprises signed letters of intent to move in at the same time.
In order to connect with the Hainan Free Trade Port, on January 1, 2017, the construction of Xuwen Port in Zhanjiang City, Guangdong Province officially started. The port includes 16 5,000-ton passenger ro-ro berths and 1 5,000-ton hazardous goods dedicated ro-ro berth.
The Ministry of Commerce will make more efforts to support Hainan in aligning with high-standard international economic and trade rules, enhancing institutional openness, and fostering new growth drivers through targeted measures, Jiang said.
"The move is aimed at expanding opening up and accelerating development," said Cai, emphasizing that Hainan's opening up is not merely about lifting restrictions, but about systematically building an institutional framework to ensure the free and efficient flow of people, goods and capital.
Performance of hybrid photovoltaic-electrical energy storage systems for power supply to buildings 157 This section summarizes the recent research progress on widely used PV-EES technologies, which can be 158 applied to the building power supply. Fig. 4 shows the review framework of the recent research progress on the system
Hybrid photovoltaic-electric vehicle energy storage system The EV (Electric Vehicle) is an emerging technology to realize energy storage for PV, which is promising to make considerable contribution to facilitating PV penetration and increasing energy efficiency given its mass production .
Hybrid photovoltaic-hydrogen energy storage system HES (Hydrogen Energy Storage) is one of important energy storage technologies as it is almost completely environment-friendly and applicable to many economic sectors besides EES . It is a promising candidate leading to a low carbon hydrogen economy .
3.2.1. Hybrid photovoltaic-battery energy storage system With the descending cost of battery, BES (Battery Energy Storage) is developing in a high speed towards the commercial utilization in building . Batteries store surplus power generation in the form of chemical energy driven by external voltage across the negative and positive electrodes.
