The Chinese are known pioneers, and recently they proved it yet again after launching a pioneering hybrid power system, with two strange towers in the Antarctic. This station is China’s fifth Antarctic research station, located on Inexpressible Island in Terra Nova Bay, East Antarctica. The station is said to accommodate 80 people during the summer and 30 in the winter, which means they have a high demand for power in a place that is deemed inhabitable for long periods.
Two strange towers in the Antarctic
According to Dou Yinke, dean of Taiyuan University’s School of Electrical and Power Engineering, 80% to 90% of the world’s Antarctic research stations still depend on fuel-powered electricity production, which causes significant environmental pollution in the polar regions.
That is why China’s Qinling Station in Antarctica launched a hybrid power system that integrates 130 kW solar, 100 kW wind, 30 kW hydrogen, and 300 kWh low-temperature energy storage battery system, part of the diesel power, which establishes it as the country’s first large-scale clean energy project on the freezing, harsh continent.
The design of the station and power system is something else. The main building is designed in the shape of the Southern Cross constellation, a tribute to the Chinese navigator Zheng He. Amongst the hybrid power stations are two strange towers in the shape of droplets, which sport the colors green, blue, and red. These two towers are wind turbines, and what’s even stranger is that they can provide power by operating on ice caps.
The Qinling station’s hybrid system is full of power
The hybrid system utilizes renewable energies to supply 60 percent of the station’s power and should decrease annual fossil fuel usage by over 100 tonnes, highlighting China’s push for greener polar research. In conditions where sun and wind energy are unavailable, the system can power the station’s 150-kilowatt maximum load for two-and-a-half hours.
The stored hydrogen supplies 30 kilowatts of power nonstop for 14 days during polar nights, enabling the short-term functioning of research tools and basic living facilities. This system is not without its challenges, as hydrogen fuel cells require cold-resistant power-up technology.
According to Dou, the hybrid system cannot fully replace traditional energy systems in the conditions of safety and stability, as there is still a lack of systematic application and development of clean energy technologies made for the Antarctic environment. This won’t slow down the Chinese station though.
Lab simulations helped develop the project
To understand all the possible challenges that lay ahead for the project, the team used lab simulations, real-environment tests, and on-site trials. The project was essentially formed in the university’s polar environment clean energy lab.
They managed to replicate the brutal Antarctic conditions, such as temperatures of minus 50 degrees Celsius and winds of 60 meters per second. A simulation research cabin imitated the project’s living quarters with outdoor chambers blasting artificial snowstorms (that’s real dedication!).
They have faced many hurdles, but the benefits are inevitable: slashed costs and protection for Antarctica’s fragile ecosystem. Plans are commencing to expand the project to China’s other polar stations and to adapt it to other harsh environments around the world.
I will dedicate my whole life to the cause. I believe we have just taken the first step on a long journey. It is a demonstration and an experiment. Key technology breakthroughs can also drive the energy revolution in the province, a major energy base in China. With clean energy, people can survive in polar regions. In the future, we may even install and test this technology on the moon and Mars. – Sun Hongbin.
It is a remarkable facility with a pioneering hybrid power system. We are excited to see future approaches to developing clean energy in Antarctica, especially with solar and wind energy being the main sources of interest.
