[Winter Olympics ask "Ji"] 100% of the venues use "green electricity" to decrypt the green Winter Olympics
[Explanation] During the Beijing 2022 Winter Olympics, all venues in the three major competition areas of Beijing, Yanqing and Zhangjiakou will use green electricity, which means that for the first time in the history of the Olympic Games, 100% green electricity will be supplied to all venues.
Green electricity refers to the electricity converted from renewable energy by means of wind power, hydropower and solar photovoltaic.
The Green Winter Olympics are embodied in various fields such as construction, transportation and power supply, all of which are aimed at reducing carbon emissions during the preparation and holding of the event, and achieving the goal of "all carbon emissions generated by the Beijing Winter Olympics will be neutralized".
The Zhangjiakou Winter Olympic Village is constructed in accordance with China's highest green building three-star standard, and all the electricity used for room heating comes from wind power.
[Concurrent] Wang Hao, architect of Tsinghua University Architectural Design Institute
This (three-star green building standard) is not only the building itself, but also the impact on the surrounding area, and even the impact on animals. It has many requirements beyond the building itself.
[Concurrent] Yan Wenjuan, Olympic Village Operation Department, Zhangjiakou Olympic Sports Construction and Development Co., Ltd.
Our Olympic Village adopts 100% green electricity, which can avoid the pollution caused by thermal power to the atmosphere.
[Commentary] Walking into the kitchen of Zhangjiakou Winter Olympic Village (Winter Paralympic Village), you will be greeted with modern kitchen utensils such as electromagnetic swing soup pot, double-head and double-tail induction cooker, and universal oven.
[Concurrent] Liu Jun, restaurant engineer of Zhangjiakou Winter Olympic Village (Winter Paralympic Village)
This is called a double head and double tail induction cooker. All the energy used in the (restaurant) is wind power generated in Zhangjiakou. This kind of environmental protection is a commitment to the world to use green energy.
[Explanation] Various venues have also used many new technologies in terms of water resources and waste disposal.
The Zhangjiakou competition area has built high-standard domestic sewage treatment facilities, and the domestic sewage in the competition area will be fully collected, fully treated and reused.
[Concurrent] Yan Wenjuan, Olympic Village Operation Department, Zhangjiakou Olympic Sports Construction and Development Co., Ltd.
We also have a lot of technologies for (saving) water, such as setting up permeable paving in the sunken square, (doing) some rainwater collection, and setting up permeable pipes below, which can realize summer watering of shrubs and the like.
[Explanation] During the Beijing Winter Olympics, more than 700 hydrogen fuel cell vehicles will be put into the Zhangjiakou competition area to provide personnel transportation and logistics support services for the event.
At present, the maximum daily hydrogen production capacity of Zhangjiakou is about 13 tons. With the opportunity of preparing for the Winter Olympics, Zhangjiakou City vigorously develops the hydrogen energy industry, forming a whole industrial chain of production, storage, transportation, addition and use.
[Same period] Zhao Hui, deputy general manager of a new energy technology company in Zhangjiakou
We use Zhangjiakou's green power to produce green hydrogen, and we are the hydrogen supply unit for the (Beijing) 2022 Winter Olympics. Our current full-load output is four tons of hydrogen per day, which can meet more than 400 (hydrogen) fuel cell buses. needs of the day.
[Explanation] It is understood that Zhangjiakou's developable wind energy resource reserves have reached more than 40 million kilowatts, and the developable solar energy capacity has reached 30 million kilowatts.
When the demand for electricity is high, Fengning Pumped Storage Power Station will send the stored electricity to the grid, which is equivalent to backing up a large "charging treasure" for the entire grid. Through energy complementation and collaborative work, the power safety operation of the Winter Olympics venues is guaranteed. .
