The lighting of the Olympic flame, which has intrigued the world, took place in an unexpected and understandable way at the opening ceremony of the Winter Olympics in Beijing on Feb. 4.Instead of lighting, the cauldron has a green heart — the first hydrogen torch in The history of the Winter Olympics, and a footnote that the Games will be carbon neutral.From magnesium, propane, and hydrogen for this Winter Olympics, the Olympic torch’s low-carbon fuel epitomizes the global effort to tackle climate change.”In the dark, technicians dressed in black and working quickly plugged six pipes from the sky into the snowflake.The first two lines to be connected are cable and cable. Snowflake’s circuit supply is switched from underground to the sky. Real-time status feedback is sent to the control room and commands are received.Then two hydrogen pipes were inserted, the fuel supply was normal, and the main torch had a ‘major artery’.Two Wiya cables will lift the snowflake and make it dance through the air.”China’s space to a report in the recording of the main torch was lit the audience hard to notice the technical details, “torch Zhao Jiawen wood jiang and Denny, based on the stage, put his hand in the” flying “the torch into the center of the” snow “, make the hydrogen gas in the air supply system with ‘snowflake’ main torch connects, hydrogen storage of hydrogen in traveling downward along the flexible hoses,Pass through the built-in gas pipe of ‘Snowflake’ to enter ‘flying’.Holding the torch, the pipe inside the shell bends and twists, and the hydrogen flows along the pipe and finally bursts out.”In August 2020, the Beijing Olympic Winter Games organizing Committee issued a notice officially specifying the use of hydrogen as fuel for hand-held torches.Hydrogen, as the cleanest and environmentally friendly fuel, only produces water and no carbon dioxide when burned. It can achieve complete zero emissions, which can truly reflect the green, low-carbon and sustainable principles of the Beijing Winter Olympics.Therefore, hydrogen fuel will be used in all relays of the Beijing Winter Olympic Games. Hydrogen fuel will be used to light the main flame of the Beijing Winter Olympic Stadium during the opening ceremony. Meanwhile, hydrogen fuel cell vehicles will be used extensively during the games to reduce pollutant emissions.The use of hydrogen energy is a strength of space.No.11 Institute of the Sixth Institute of China Aerospace Science and Technology Corporation (Beijing) is the leading unit for the development of hand-held torch and main torch for the Beijing Winter Olympic Games. As the only research unit of liquid hydrogen and oxygen engine in China, the institute has accumulated decades of experience in the research of hydrogen energy. The three types of hydrogen and oxygen engine developed by the institute,In the Beidou Project, Chang ‘e project, Mars exploration and space station construction and other major engineering projects have a perfect performance.When talking about the development process of the torch, Liu Yue, the technical director of the main torch development team, recalled that at first, people referred to the design of the main torch of the previous Olympic Games, and thought that the main torch should be large in size and high in flame. Therefore, in the preliminary stage of key technology research, the minimum hydrogen fuel consumption should also reach 2,000 cubic meters per hour.However, zhang surprised them with his idea of a “micro fire”, holding the torch in the Snow Center for a long time, with a hydrogen fuel flow of about 1.2 cubic meters per hour.Previous Olympic Games have used alkanes as the main fuel for the torch, with only the 2020 Tokyo Olympics using hydrogen fuel, the report said.The main sources of alkanes are oil and natural gas, which are cheap and calorie-burning.Hydrogen energy utilization involves “preparation, storage, transportation and application”, which requires comprehensive utilization level of hydrogen energy.As the smallest element in the world, how can hydrogen be guaranteed not to leak during transportation and transmission?How to ensure the stable and continuous burning of the main torch?In addition, hydrogen has no color, so it has to undergo a flame reaction;The flame can’t be like a rocket engine, it has to be curved…The project team had to solve not only technical problems, but also artistic ones.To this end, the sixth academy torch development team composed of 11 (Beijing) and 101 institute of the sixth Academy of China Aerospace Science and Technology Group spent two years to overcome various problems of hydrogen fuel torch.The Bird’s Nest cauldron for the 2008 Beijing Olympics was lit by natural gas.According to China Youth Daily, the opening and closing ceremonies of the Beijing Olympic Winter Games organizing Committee (BOCOG) reviewed technical data in 2008 and found that the cauldron lit by Chinese gymnast Li Ning consumed about 5,000 cubic meters of gas per hour.To maintain its enormous flame, the Bird’s Nest is equipped with a gas station that pumps power day and night.The creators were taken aback at the number.”Of course the burning fire is the embodiment of the human Olympic spirit, but is it environmentally friendly?”Zhang yimou said.The main flame of the Beijing Winter Olympic and Paralympic Games was burned for more than a month, and it is unknown how much carbon dioxide will be emitted.Compared with previous flaming torches, the “flying” torch, the last leg of the Winter Olympics, “seamlessly connects” with the main flame. There is no ignition process, and the subversive “small flame” can save 99.9% of energy, fully reflecting the concept of environmental protection.Hydrogen, supplied by Sinopec Yanshan Petrochemical, was used as fuel to “light” the cauldron during the opening ceremony.In order to ensure hydrogen supply for the main torch, Yanshan Petrochemical has set up a hydrogen guarantee team for the Winter Olympic Games main torch, which has worked out detailed work plans and guarantee measures from hydrogen filling, testing and transportation to ensure the high quality and safety of hydrogen supplied.At the same time, yanshan Petrochemical hydrogen new energy plant was delivered on January 2, 2020, and successfully started operation on March 27, 2020. Its design scale is 2,000 standard cubic meters per hour, aiming to provide guarantee for hydrogen fuel cell vehicles during the Winter Olympics.The facility can produce hydrogen for fuel cell or electronics industries, and the entire process will be completed from smooth operation to product delivery by December 16, 2020.In January 2021, yanshan Petrochemical has achieved mass production of hydrogen for batteries.Green hydrogen, independently developed by CNPC, lit up the torch platform in The Zhangjiakou area of the Beijing Winter Olympic Games on The evening of February 4.This is the only Olympic torch lit by green hydrogen, is the winter Olympics nearly 100 years of history of the first green hydrogen torch as a fuel.Green hydrogen refers to hydrogen produced by electrolysis of water using renewable energy.In order to highlight the theme of “green Winter Olympics”, CNPC selected clean, environmentally friendly and low-carbon hydrogen production equipment and technology throughout the system, and finally selected solar water electrolysis hydrogen production equipment of its research Institute of Exploration and Development to provide green hydrogen for the Torch of the Winter Olympics.At the Beijing Winter Olympics, hydrogen supplied by petrochina lit the torchbearers at three venues, from the Water Cube (Ice Cube) to yanqing and then zhangjiakou in Hebei province.In addition to supplying hydrogen for the Olympic torch, CNPC also provided hydrogenation service for the Winter Olympic hydrogen vehicles through four hydrogenation stations and integrated energy service stations.During the Winter Olympics, the hydrogen supply capacity will reach 5,500 kg/day, providing services for nearly 1,000 hydrogen fuel cell vehicles, and the mileage is expected to exceed 2 million kilometers.The “green” of the Beijing Winter Olympics goes far beyond the torch.In mid-January this year, the BoCOG released the Sustainable Development Report for the Beijing Winter Olympic Games (Pre-Games), detailing the phased progress of the sustainable development work in preparation for the Winter Olympic Games.In terms of strict low-carbon management, the 2008 Beijing Olympic Venues were fully utilized to reduce carbon emissions from the source.At the same time, low-carbon venues will be built, and all venues will meet green building standards. Four ice venues will use carbon dioxide refrigerant for the first time in the history of the Winter Olympics. Over 50,000 square meters of ultra-low energy consumption demonstration projects will be built.Fully use low-carbon energy, relying on cross-regional green electricity trading mechanism, 100% of the regular energy of all venues during the games will use green electricity;To build a low-carbon transportation system, energy-saving and clean energy vehicles accounted for more than 80% of the vehicles during the race.On the basis of the comprehensive implementation of emission reduction measures, we will actively expand carbon compensation channels. The governments of Beijing and Zhangjiakou donated forest carbon sequestration to the Beijing Winter Olympic Games. China National Petroleum Corporation, State Grid Corporation of China and Three Gorges Corporation also sponsored carbon neutral products for the Beijing Winter Olympic Games.Liu Yumin, head of the planning and construction department of the Beijing Winter Olympics Organizing Committee, said at a press conference on January 13 that the power supply of the Beijing Winter Olympics will basically rely on the existing municipal power grid, and all venues will be supplied with green power through green power transactions in accordance with the national green power market trading rules.According to estimates, from the first green electricity transaction in June 2019 to the end of the 2022 Winter Paralympic Games, the venues in Beijing, Yanqing and Zhangjiakou are expected to use 400 million kilowatt-hours of green electricity, which can reduce the burning of 128,000 tons of standard coal and reduce carbon dioxide emissions by 320,000 tons.The Games also achieved low-carbon transportation.’The Beijing area is located on a plain and will mainly use pure electric and natural gas vehicles,’ Li Sen, director of the general planning department of the Beijing Winter Olympics Organizing Committee, said at the conference.The yanqing and Zhangjiakou race areas are dominated by hydrogen cars, mainly to meet the needs of mountainous areas.(Source: The Paper) Editor: Han Luying
