The Beijing Winter Olympics are in full swing, with high-tech venues that will keep athletes alive and break multiple records. For example, at the National Speed Skating Hall, known as the "Ice Ribbon", athletes from the Netherlands, Sweden, China, Japan and the Russian Olympic Organizing Committee set 12 Olympic records and 1 world record here.
In addition to setting records for competition results, this Year's Winter Olympics also set records in energy conservation and emission reduction.
"Striving to host a carbon-neutral Winter Olympics" is a solemn commitment made by Beijing and Zhangjiakou when they bid to host the 2022 Winter Olympic and Paralympic Winter Games. The first is to try to be as low-carbon as possible, according to estimates, the greenhouse gas baseline emissions of the Beijing Winter Olympics need to be controlled at about 1.306 million tons of carbon dioxide equivalent, which is equivalent to the emissions of burning 500,000 tons of standard coal, which is also a small carbon peak target.
Next is carbon neutrality, which is not a very good means, usually afforestation to increase carbon absorption, carbon capture or purchase carbon sinks to offset emissions. Fortunately, the local governments of Beijing and Zhangjiakou are very supportive of the Winter Olympics, donating a total of 1.1 million tons of carbon dioxide equivalent carbon sinks, plus petroChina, State Grid, Three Gorges Group and other three official cooperative enterprises also sponsored 200,000 tons of carbon sinks, in short, through the joint efforts of all parties, the Carbon Emissions of the Beijing Winter Olympics will be all neutralized.
Well, the neutralization problem has been solved, and the Flag has been established, but it is not easy to achieve a low carbon emission of 1.306 million tons, and the Beijing Winter Olympic Organizing Committee needs a multi-pronged approach to reduce the carbon emissions generated by the Beijing Winter Olympics as much as possible.
For example, all venues have achieved renewable energy green power supply, all venues have reached green building standards, for the first time, carbon dioxide refrigerants that do not destroy the ozone layer have been used on ice venues of the Winter Olympic Games, the Winter Olympic Organizing Committee has transformed waste factories to build a green and high-standard Shougang office area of the Winter Olympic Organizing Committee, and a low-carbon transportation system has been built during the Games. The construction of a low-carbon transportation system is particularly important because it is the most socially promoted project.
The beijing winter olympics are distributed in Beijing, Zhangjiakou and Yanqing, and the winter Olympic players and participants need to move frequently in the three places. In accordance with the principle of "plain electricity, mountain hydrogen", the Winter Olympic Organizing Committee has adopted a large number of electric vehicles and hydrogen fuel cell vehicles, which is also the first large-scale demonstration application of hydrogen fuel cell vehicles. Why will hydrogen fuel vehicles become the protagonists of this Winter Olympics? This is because the mountain roads in Zhangjiakou and Yanqing are steep and the temperature is very low, which requires a high reliability of electric vehicles. The hydrogen fuel cell vehicle has strong adaptability to the low temperature environment, the energy replenishment time is only a few minutes, the endurance is high, and it can achieve zero emissions, so it has become the protagonist of the game.
Let's take a look at the hydrogen fuel cell vehicles that are racing between the Winter Olympics.
According to the official data of the Winter Olympic Organizing Committee, the event demonstrated the operation of more than 1,000 hydrogen energy vehicles, and equipped with more than 30 hydrogen refueling stations, including buses, buses, cars, special vehicles, etc., mainly provided by Toyota Motor, BAIC Group, Foton Motor, Yutong Bus and other car companies.
