What do the Winter Olympics mean to you? Wonderful events, fierce competition for medals, the strength and beauty displayed by athletes, surging patriotic feelings, etc., then you know about the closing of the Winter Olympics What month and day is the formula? The editor below has sorted out the dates of the closing ceremony of the 2022 Winter Olympics for everyone. I hope you like it!

The closing ceremony time of the 2022 Winter Olympics

The 24th Winter Olympics will be held in It will be held in Beijing and Zhangjiakou, China from February 4 to February 20, 2022.

Winter Paralympic Games 2022 specific time

The Beijing Winter Olympics is scheduled to open on February 4, 2022 (Friday) and close on February 20 (Sunday) , the total duration is 16 days. The Beijing Winter Paralympics is scheduled to open on March 4, 2022 (Friday) and close on March 13 (Sunday). In addition to the competition venues, the opening and closing ceremonies will be held in the Bird's Nest.

How long will the opening ceremony of the Beijing Winter Olympics be?

The duration will be compressed to less than 100 minutes. The rehearsal, production and rehearsal of the opening and closing ceremonies of the Beijing Winter Olympics are proceeding in an orderly manner. Taking into account factors such as temperature and epidemic prevention, the opening ceremony has been adjusted in length and structure accordingly.

How does the Beijing Winter Olympics torch achieve green environmental protection

At the opening ceremony of the Beijing 2022 Winter Olympics held on the evening of February 4, in order to practice the concepts of green and environmental protection, we tried our best to In order to minimize carbon emissions, the small flame of the last torch became the main torch of this Winter Olympics. It was placed in the center of a huge snowflake composed of the guide boards and olive branches of each participating party. The ingenuity of returning to nature is really amazing.

Hydrogen energy lights the Olympic torch

According to previous reports, at the 2008 Beijing Summer Olympics, the raging fire of the main torch consumed about 5,000 cubic meters of natural gas an hour and emitted a large amount of carbon dioxide. . In order to supply gas to the main torch, the Bird's Nest is even equipped with a gas station to deliver power to it day and night.

After transforming the torch into a "micro-fire", the carbon emissions produced will be only about one-fifth thousandth of the previous one. Unlike previous Olympic Games, which used a large amount of gases such as liquefied natural gas or propane as torch fuel, the Beijing 2022 Winter Olympics will use hydrogen energy as torch fuel for the first time. The hydrogen fuel for the torch during this Winter Olympics comes from Sinopec and PetroChina.

According to Sinopec, the hydrogen provided by Sinopec Yanshan Petrochemical was used as fuel to light the main torch of the Winter Olympics at the opening ceremony. At this Winter Olympics, all domestic torch relays used hydrogen fuel. Hydrogen fuel was used to light the main torch of the Winter Olympics during the opening ceremony. During the event, a large number of hydrogen fuel cell vehicles were used to reduce pollution emissions, which reflected the Olympic spirit and "green" and " further integration of "environmental protection".

Hydrogen supplied by China National Petroleum Corporation lit up the Winter Olympics torch platforms at the Ice Cube, Yanqing competition area and Hebei Zhangjiakou competition area.

In the Zhangjiakou competition area of ??the Winter Olympics, green hydrogen independently developed by China National Petroleum Corporation lit up the Taizi City Torch Platform. According to PetroChina, this is the only torch lit by green hydrogen at this Winter Olympics, and it is also the first torch to use green hydrogen as fuel in the nearly 100-year history of the Winter Olympics.

Hydrogen is considered the cleanest and most environmentally friendly fuel. Its combustion products only produce energy and water, making it a completely zero-emission fuel. According to the source of hydrogen production, hydrogen produced from coal as raw material is called "grey hydrogen", hydrogen produced from natural gas is called "blue hydrogen", and hydrogen produced by electrolysis of water from renewable energy is called "blue hydrogen". "Green hydrogen" is the most environmentally friendly and green hydrogen.

The "Two Barrels of Oil" Winter Olympics Technology Competition

In order to ensure energy supply during the Winter Olympics, PetroChina and Sinopec have also made many arrangements.

Yanshan Petrochemical’s hydrogen energy new energy device is an official strategic cooperation project between Sinopec and the Beijing 2022 Winter Olympics. It achieved one-time start-up in March 2020 and has a design scale of 2,000 standard cubic meters per hour.

Since Yanshan Petrochemical's first battery hydrogen vehicle left the factory on December 16, 2020, it has supplied a total of more than 290 tons of fuel cell hydrogen to the market.

In order to ensure energy supply during the Winter Olympics, Sinopec has deployed 49 oil supply stations, 29 LNG filling stations and 4 hydrogenation stations in Beijing and Hebei.

During the current Winter Olympics, the four hydrogenation stations and comprehensive energy service stations built by PetroChina have a hydrogen supply capacity of 5,500 kg/day during the Winter Olympics, which can power nearly a thousand hydrogen battery vehicles. Provide services and the mileage is expected to exceed 2 million kilometers.

As an important part of PetroChina’s efforts to create a growth pole for the low-carbon energy industry, hydrogen energy has also become the focus of the oil giant’s layout in recent years. According to PetroChina, since the establishment of a green hydrogen core technology research team, PetroChina has made major breakthroughs in the core technology of solar electrohydrolysis catalysts, and some hydrogen production materials have reached the international leading level.

During the 2008 Beijing Olympics, the natural gas produced by PetroChina lit the main torch of the Bird's Nest that year. In 2022, the green hydrogen produced by PetroChina lit the Winter Olympics torch. With the introduction of the domestic carbon peak and carbon neutrality policy, PetroChina and Sinopec are also moving forward on the road to green and low-carbon transformation. The two Olympic Games have also witnessed this process.
