About 160 kilometers northwest of Beijing, the town of Zhangjiakou with its rugged terrain offers some of the richest wind and solar resources in China. Renewables account for almost 50 % of the city’s energy output with a lot less than a third of its complete solar and wind prospective of 70 gigawatts put in so significantly.

That would make it an best cohost with Beijing for the 2022 Winter Olympic and Paralympic Games, which China designs to make the greenest however. The plan is to electricity all 26 venues thoroughly with renewables, marking a very first in the games’ historical past.


The Beijing 2022 Organising Committee aims to make the game titles carbon neutral, or as near as possible—a benchmark for the Intercontinental Olympic Committee’s mission to make the Olympics carbon good by 2024.

Moreover remaining a symbol for President Xi Jinping’s bold purpose of China being carbon neutral by 2060, the 2022 online games ought to drive sustainable improvement in the area. The party has already aided Beijing thoroughly clean up its skies and setting, and has fired up community electrical power-engineering marketplaces. It will also be a world-wide stage to showcase new vitality-efficiency, alternate-transport, and refrigeration systems.

The Olympics will account for only a little portion of the country’s once-a-year electric power intake. Powering them with thoroughly clean energy resources will not be tricky offered China’s plentiful renewable ability, suggests Michael Davidson, an engineering-units and worldwide-plan specialist at the College of California, San Diego.

But Davidson also details out that insufficient infrastructure to take care of intermittent renewables and electrical power-dispatch techniques that never prioritize them indicate that considerably of China’s inexperienced-ability ability is generally not place to use. And for the reason that the match venues are linked to a grid that is driven by a wide range of sources, asserting that all the electric power utilised at the game titles is 100 per cent from thoroughly clean strength sources is “complicated,” he claims. Nonetheless, the games will be important in raising the profile of inexperienced vitality. “The hope is that this procedure will put into position some establishments that could support leverage a a great deal broader-scale move to eco-friendly.”

The Video games will give a worldwide stage to showcase new vitality-efficiency, alternate-transport, and refrigeration technologies.

Situation in level: The adaptable DC grid place into place in Zhiangjiakou in 2020 will let 22.5 billion kilowatt-hours of wind and photo voltaic energy stream from Zhiangjiakou to Beijing every single 12 months. By the time the Paralympics conclude in March, the sport venues are predicted to have consumed about 400 million kWh of electricity. If all of it is certainly delivered by renewables, that should decrease carbon emissions by 320,000 tonnes, according to sports activities outlet Within the Games. Following the athletes go home, the versatile DC grid will keep on to cleanse up all-around 10 p.c of the capital’s immense electricity use.

Environmentally friendly transport infrastructure getting constructed to shuttle athletes and spectators in between venues will also be part of the games’ long lasting legacy. A clean energy–powered superior-velocity railway that will take 47 minutes to vacation among Beijing and Zhangjiakou was inaugurated in 2019. Additional than 85 % of public-transport motor vehicles at the Olympics will be driven by batteries, hydrogen fuel cells, or natural gas, in accordance to point out media.

In August, officials at the Chinese cash revealed a five-12 months hydrogen-power prepare, with goals to build 37 fueling stations and have about 3,000 gas-mobile motor vehicles on the road by 2023, for which the Olympics should also be a stepping-stone. By now, hydrogen fueling stations developed by China’s petrochemical huge Sinopec, Pennsylvania-based Air Solutions, and French company Air Liquide have cropped up in Beijing, Zhiangjiakou, and the Yanqing competition zone positioned in amongst.

In Yanqing on your own, 212 gasoline-mobile buses manufactured by Beijing-primarily based Beiqi Foton Motor Co. will shuttle spectators about. Even the iconic Olympic torch will melt away hydrogen for its flame.

Even the iconic Olympic torch will burn off hydrogen for its flame.

The 2022 event will also put a limelight on climate-friendly refrigeration. The enormous 12,000-square-meter pace-skating oval in downtown Beijing—8 times the dimension of a hockey rink—will be the very first in the world to use carbon dioxide for producing ice.

“We’ve constructed skating rinks with carbon dioxide immediate cooling but hardly ever a pace-skating oval,” suggests Wayne Dilk of Toronto-based mostly refrigeration organization CIMCO Refrigeration, which has created most of the Countrywide Hockey League arenas in North The usa and made and supplied consulting solutions for the Olympics’ icy venues.

Ice-rink technological know-how usually depends on refrigerants siphoning heat absent from brine circulated under the flooring, Dilk clarifies. But CO2-centered cooling devices, which are having extra common predominantly in Europe and North The united states for supermarkets, food items-manufacturing crops, and ice rinks, use CO2 both equally as the refrigerant and for transporting heat away from under the flooring in which it is pumped in liquid sort.

CO2 is a weather villain, of class, but typical hydrofluorocarbon refrigerants are worse. The popular R-22 kind of Freon, for example, is about 1,800 moments as potent as a greenhouse gas. CO2 cooling methods are also 30 percent far more energy economical than Freon, says Dilk. As well as, the CO2 technique makes higher-temperature waste warmth, which can be utilized for house heating and scorching water. And when the process is far more highly-priced to establish due to the fact it runs at better stress, the temperature across the substantial surface area stays within a variety of only .5 °C, giving additional uniform ice. Reliable temperature and ice top quality generate much better aggressive racing instances. The Beijing 2022 hockey arenas and sliding centre for bobsled and luge use climate-pleasant ammonia or Opteon as refrigerants. Apart from getting a vital part of the greenest Winter Olympics, these point out-of-the-art ice venues need to seal the deal for a further aim China has in 2022: to create by itself as a globe-course winter season sporting activities and tourism vacation spot.

This article seems in the January 2022 print difficulty as “China’s Eco-friendly Winter Olympics .”
