Nature's previous 2016 article shows that the 2008 Beijing Olympic Games gave birth to the most scientific research, it can be said that we redefined the scientific and technological attributes of the Olympic Games, and the technology displayed by each host country since then has its own characteristics and represents the future development direction. However, why did the Tokyo 21 Olympics and the 22nd Beijing Winter Olympics invariably focus on hydrogen energy?
In the Tokyo Olympic Games in Japan, the strength of the country was poured into betting on hydrogen energy as the development direction of new energy, but the result was high and low. The mainland has spent countless energy to create pure electric vehicles as the mainstream of new energy. At this time, why not expand the advantages, continue to open the gap, and instead pay for others in reverse, and develop hydrogen energy without advantages? The answer lies in the mainland's new energy map.
First of all, the advantages of hydrogen energy, as an ideal secondary energy source, can be produced and stored, the energy density is far higher than that of oil and coal, and does not emit pollutants. The mainland's photovoltaic and wind energy is mainly concentrated in the northwest, while the large provinces with large electricity are concentrated in the southeast, the uneven distribution of energy means that a large number of curtailment, and if the waste part of the electricity is used for the production of hydrogen energy, it can play a role similar to lubricant, so that the mainland's new energy strategy can develop sustainably and rapidly.
It is precisely because of these advantages of hydrogen energy that hydrogen energy has become one of the key projects of the Winter Olympics. However, if the Winter Olympics just want to promote hydrogen energy, then the pattern is small, and what we really want to do is carbon neutrality.
The carbon emissions generated by the Beijing Winter Olympics will be integrated, how is this done? This is an energy map behind the Beijing Winter Olympics, its gold content is so high that once unveiled, all countries will be red-eyed, the world's leading wind, photovoltaic and water clean energy, the world's first flexible DC power grid project and a ride on the dust of UHV technology, it can be said that this Winter Olympics to the world to show the future carbon neutral era of power system model.
To know that this is not only the world's unique, but also has been complete to the stage of commercialization, other countries do not say to keep up with the pace, many of which are key technologies they have not yet touched the threshold, in the future any country wants to make a difference in clean power, are indispensable to our support of this set of technology.
In addition, the refrigerant of the Winter Olympic venues, the tradition is to use Freon, which will destroy the ozone layer, and in order to pursue absolute green environmental protection, we actually moved out a technology that shocked the world a while ago - supercritical carbon dioxide refrigeration, his principle is to collect carbon dioxide from industrial exhaust gases, processed to a supercritical state under specific conditions, a fluid state between solid and liquid as a refrigerant.
Why is this technology shocking the world? Because this is a key technology applied to fourth-generation nuclear power plants and next-generation nuclear-powered aircraft carriers. With this technology, the venues of the Winter Olympics can ensure that the temperature of the entire ice surface is absolutely average, and no matter how many laps the athletes draw, the ice surface is intact. Seeing that China actually moved this technology to the Olympic venues, the experts of the International Olympic Committee kept lamenting that this was a great decision. Since there are so many carbon-neutral black technologies, why should hydrogen energy be a key project?
There are really objective reasons for the large-scale use of hydrogen vehicles at the Beijing Winter Olympics. The Beijing Winter Olympics are divided into three major competition areas, namely Beijing, Yanqing and Zhangjiakou. The Winter Olympics are originally low-temperature sports, and the venues in Yanqing and Zhangjiakou are dominated by snow-capped mountains, and the temperature is particularly low, which has higher requirements for docking vehicles.
And electric vehicles can not guarantee the endurance in this low temperature climate, then the advantages of hydrogen energy vehicles are reflected. The Olympic Committee has formulated the policy of "electricity is electricity, and hydrogen is hydrogen", and 1,000 hydrogen energy buses are introduced from Japan to be used with electric vehicles. In this way, the choice of hydrogen energy vehicles in the Winter Olympics seems to be forced to be helpless. But in fact, in addition to this Winter Olympics, in the northern region of the mainland and some high-latitude countries, it is actually more suitable for the development of hydrogen energy vehicles. Coupled with the advantages of hydrogen energy itself, the mainland has long begun to vigorously layout hydrogen energy.
Taking Beijing as an example, it is planned to promote more than 3,000 hydrogen fuel cell vehicles in 2023, and the scale of the hydrogen energy industry will be expanded to 50 billion. In 2025, it will double to 100 billion, with the goal of building a first-class international hydrogen city in the future. The plans of other cities are also similar, and they are full of efforts to complete the last piece of the puzzle of hydrogen energy.
In order to achieve this goal, Beijing took the initiative to put its hopes on the Winter Olympics and established a hydrogen demonstration base for the Winter Olympics. In addition to hydrogen fuel vehicles, the Olympic Organizing Committee has also established more than 60 hydrogen refueling stations along the route as supporting facilities, and has carried out strategic alliances with Hebei and Tianjin to delve into hydrogen fuel cell technology and build a national hydrogen energy demonstration zone.
Although we have not yet taken the lead in hydrogen energy, at least some of the worse than the desperate Japan, but as the icing on the cake, China's future hydrogen energy road will be much more relaxed.
