CCTV News: On January 6, multiple departments released the latest economic data, showing the resilience and vitality of my country's economic development. The "combination punch" of tax preferential treatment continues to stimulate the innovation vitality of enterprises

The latest data released by the State Administration of Taxation shows that in the first 11 months of 2024, my country's main policies to support scientific and technological innovation and manufacturing development were tax cuts and fee reductions and tax refunds of 2297.9 billion yuan. A series of "combination punches" of tax incentives continue to stimulate the innovation vitality of enterprises.

By policy type, in the first 11 months of 2024, we supported increasing investment in science and technology and transfer of results, with tax reduction and fee reduction and tax refund of 803.6 billion yuan; supported equipment updates and technological transformation, with tax reduction and fee reduction and tax refund of 80 billion yuan; supported high-quality development of the manufacturing industry, with tax reduction and fee reduction and tax refund of 968.3 billion yuan. China's retail industry prosperity index rebounded significantly in January

The China Federation of Commerce released the latest data on January 6 showing that driven by the implementation of the policy of New Year's goods consumption during the Spring Festival and the old-for-new trade-in policy for commodities such as household appliances, in January, China's retail industry prosperity index was 51.1%, up 0.7 percentage points month-on-month and 0.2 percentage points year-on-year, and the consumer market continued to rebound and improve. my country has accelerated the layout of national data infrastructure

The new year and new atmosphere are the right time to strive for it. In recent days, a number of major projects in my country have made new progress. my country accelerates the layout of national data infrastructure

The reporter learned from the National Data Bureau on January 6 that my country is accelerating the layout of national data infrastructure and issued the "National Data Infrastructure Construction Guidelines" for the first time to promote large-scale data sharing and utilization.

The National Data Infrastructure is a new type of infrastructure that provides data collection, transmission, processing and other services to the society, including data circulation and utilization facilities, network facilities, computing power facilities, security facilities, etc.

It is estimated that the data infrastructure will attract about 400 billion yuan of direct investment every year. By 2028, my country will achieve basic coverage of large and medium-sized cities across the country. The railway express logistics demonstration train with a speed of 120 kilometers per hour was launched

On January 6, three freight trains with a speed of 120 kilometers per hour were launched from Beijing, Hefei, Guangzhou and other places, marking the official launch of my country's railway express logistics demonstration trains. There are 6 demonstration trains in total, and the operating hours of trains from Beijing, Yiwu to Guangzhou are 33 hours and 17 hours respectively, which is about 30% shorter than the previous fastest freight train. my country successfully launched the 25 satellite

At 04:00 Beijing time on January 7, 2025, my country used the Long March 3B carrier rocket at the Xichang Satellite Launch Center and successfully launched the 25 satellite. The satellite successfully entered the predetermined orbit, and the launch mission was a complete success.

This satellite is mainly used for satellite fuel replenishment and life extension service technology verification. This mission is the 555th flight of the Long March series of launch vehicles. my country's largest tidal flat photovoltaic power station was put into production today

On January 7, my country's largest tidal flat photovoltaic energy storage power station, Huadian Laizhou's large-scale saline-alkali tidal flat photovoltaic power station, was put into production and power generation on the banks of the Bohai Bay. Large areas of saline-alkali land have turned into a new oasis of clean energy.

The Huadian Laizhou large-scale saline-alkali mudflat photo storage integration project is one of the third batch of large-scale wind power photovoltaic bases in the country, with an installed capacity of 1,000 megawatts and a supporting construction of 200 megawatt/400 megawatt-hour electrochemical energy storage project. The power station integrates "photovoltaic power generation + salt production" to realize the composite industrial model. News link: Tidal flat photovoltaic energy storage power station

Tidal flat photovoltaic energy storage power station usually refers to photovoltaic energy storage projects built in complex areas such as sandy and silt along the coast with excellent sunshine conditions.

Take the Huadian Laizhou saline-alkali mudflat integrated light storage project as an example, the annual average sunshine time here reaches more than 2,600 hours, and the average sunshine time is more than 7 hours a day, which can convert rich solar energy resources into electricity.

In addition, due to the intermittent and instability of photovoltaic power generation, the power station has also built an energy storage system to store excess solar energy in the battery to release it when there is insufficient light or peak power demand at night. The liquid air energy storage power station is successfully connected to the grid.

Recently, the liquid air energy storage power station located in Shijiazhuang, Hebei has been successfully connected to the grid. This new energy storage technology generates 4,000 degrees of electricity per day, which can meet the electricity consumption of more than 400 households in a day.

In the liquid air energy storage power station located in Shijiazhuang, Hebei, staff closely monitor the operation of the equipment in the command and dispatch center. After three months of full-load trial operation, the grid-connected power generation and trial operation tasks were successfully completed.

Zhe Xiaohui, Secretary-General of Hebei Energy Storage Industry Technology Research Institute, introduced that during the trough period of electricity consumption, a refrigerator is driven by electric energy, reducing the ambient air temperature to minus 170℃ and turning it into liquid state. When power generation is needed during peak electricity consumption, the liquid air is heated up and turned into gaseous air, so that its volume can expand more than 600 times, pushing the expander's impeller to rotate and generate electricity.

Compared with conventional energy storage, liquid air energy storage has many advantages such as low cost, safer, and not subject to geographical conditions, especially in the fields of renewable energy consumption, grid peak shaving, etc.
