Modern Express News (Special Correspondent Liu Jingyan, Deng Wenting, Wen / Photo) Green Olympics is one of the four major Olympic concepts of the Beijing Winter Olympic Games. As the only national renewable energy demonstration zone in China, how can Zhangjiakou help the Green Winter Olympics and low-carbon Winter Olympics?
On February 9, a Modern Express reporter followed the interview group and visited the Zhangjiakou Renewable Energy Demonstration Zone Energy Big Data Center, the R&D Company of Hydrogen Fuel Cell Engines, the Zhangjiakou Hydrogen energy and Renewable Energy Research Institute, and the Chuangba Hydrogen Refueling Station.

Green electricity from Zhangjiakou covers venues in Beijing and Zhangjiakou
"The wind from Zhangbei lights up the lights of Beijing." This is something that The people of Zhangjiakou are proud of. How is it achieved?
As the only national-level renewable energy demonstration zone in China, Zhangjiakou is the hometown of the wind and the ocean and light. The flexible DC power grid is the first in the world, and the 100 MW compressed air energy storage is the international leader. The Zhangbei Flexible DC Power Grid Experimental Demonstration Project adopts the world's most advanced flexible DC power grid transmission technology to safely and efficiently transmit green electricity from Zhangjiakou to Beijing, and achieve full coverage of the green power grid in Beijing and Zhangjiakou competition areas.
Liang Lixin, deputy director of the Party Building Department of the State Grid Jibei Zhangjiakou Wind, Photovoltaic Storage and Transmission New Energy Co., Ltd., introduced that the National Wind and Solar Storage and Transportation Demonstration Project is the world's largest comprehensive demonstration project of new energy integrating wind power generation, photovoltaic power generation, energy storage devices and intelligent transmission. The first phase of the project was completed and put into operation on December 25, 2011, and it has been 11 years since then.
"As a benchmark project for the Green Olympics, we have continuously transported the high-quality, safe and reliable green electric energy output to the venues of the Winter Olympics through the optimization and upgrading of wind and solar storage and transportation, joint power generation and operation mode, including the overall improvement and improvement of the intelligent wind farm." Liang Lixin said that the flexible DC power grid solves the problem of the source of green electricity in the Beijing Winter Olympic venues, ensuring that all the venues of the Olympic Games can use 100% of the green electricity, "Athletes are fighting on the track, and the employees of the State Grid Corporation are going all out in the process of maintaining electricity and achieving a stable supply of green electricity."

【Transportation】
Domestic hydrogen fuel cell engines can be started at a low temperature of minus 35 °C
In the Zhangjiakou Renewable Energy Demonstration Zone, in addition to the green power system, it is worth mentioning the green transportation system.
△ Hydrogen fuel cell engine
During the Winter Olympics, domestic hydrogen fuel cell vehicles are used for connection during the event. How did the hydrogen fuel cell engine perform in the low temperature environment of the competition area? Shi Jiannan, commercial director of Yihuatong Power Technology Co., Ltd., introduced that the company's self-developed and mass-produced hydrogen fuel cell engine has the technical advantages of low temperature start at minus 35 °C and low temperature storage at minus 40 °C, which can meet the use of different application scenarios such as medium and long-distance, heavy-duty market, intercity passenger and freight transportation, sanitation, etc., and achieve full coverage of different road application scenarios. The company, together with vehicle companies, invested 212 and 515 hydrogen fuel cell vehicles in Yanqing and Chongli respectively.

"During the Winter Olympics, hydrogen energy has played a big role in transportation, torches and other aspects, providing a very good opportunity for the development of renewable energy." Wang Hewu, executive director of Zhangjiakou Hydrogen and Renewable Energy Research Institute, introduced. Taking the opportunity of serving the Beijing Winter Olympics, the research institute accesses the operation data of Zhangjiakou Hydrogen Plant, Hydrogen Refueling Station and Hydrogen Fuel Cell Vehicle, covers the entire hydrogen energy industry chain, and optimizes the development of the hydrogen energy industry by monitoring the operation and production process of each link in real time.

At the last stop of the interview trip, the reporter came to the Chuangba hydrogen refueling station. Workers are "hydrogenating" hydrogen fuel cell buses." Each car can be filled in about 15 minutes. We have done extreme tests, and the range is 406 kilometers, which can guarantee the use of the bus in a day. Wang Libing, director of the hydrogen refueling station, said.
