Argentina Leads the Way in Antarctic Energy Transition with 100% Renewable Solar Power
Argentina has taken a significant step towards energy transition by installing solar panels in the Antarctic to provide 100% renewable electricity. The feat was accomplished at the Marambio Base, 60 kilometers from Vega Island, where similar installations were also made.
The execution was spearheaded by researchers from the National Atomic Energy Commission (CNEA), specifically the Solar Energy Department, who are also conducting glacier studies that reveal alarming data on global warming.
Domestic Solar Generators Power Up the Antarctic
The installation of solar panels in the Antarctic began in 2014. The latest installation took place midway through this summer’s season when a CNEA team arrived at Marambio Base to install the panels for the fourth time. The generators are of the domestic type, similar to those used in households, and have a capacity akin to what would be produced in urban installations.
Hernán Socolovsky, an engineering electronic specialist and doctoral graduate in Photovoltaic Technologies, heads the Solar Energy Department. He notes that while the panels are small, the first ones installed have functioned for 14 years. They have a generation capacity of 60%, equivalent to what a household would consume, and an estimated lifespan of 50 years. Through an energy converter, they supply the main grid.
These panels work with lithium batteries to ensure supply during nighttime and low-sunlight days. The installation process is the only variation, according to Socolovsky. "For example, to tighten a bolt, we had to take off our gloves, but our hands could only tolerate the cold for a few seconds. So, we’d put the bolt on, give it three turns, and then put our gloves back on because our hands would turn purple. That’s how a task that normally takes half an hour could take a whole day," he recounts.
Solar Panels: The Perfect Solution for Antarctic Refuges
Before the panels, fuel drums posed safety risks due to their logistical challenges. With the advent of photovoltaic energy, emission of pollutants and costs have been reduced.
To increase panel production, investigators at the CNEA aim to fabricate more panels using the extensive knowledge possessed by their personnel. They even created a series of panels for the Saocom satellites, which monitor Earth.
Physicist Marcela Barrera is working on cell creation to avoid imports, as Argentina possesses the specialized knowledge for component testing and panel assembly. Currently, China controls 60% of the market, making material acquisition easier.
Socolovsky emphasizes the importance of safe installation: "In the Antarctic, a challenging part of the work is finding a safe way to mount them. A company once installed panels unsafely, and they blew away. Our installations have been problem-free because we have a maintenance team dedicated to evaluating the robustness of our mounts."
The investigators are determined to develop 100% renewable energy in the Antarctic. Aware of advancing global warming, they hope to counter environmental deterioration along the Pacific Ring of Fire.
