(EUN) TOM HEGEN - AERIAL PHOTOGRAPHY

Lithium extraction fields in South America have been captured by an aerial photographer in stunning high definition.

But while the images may be breathtaking to look at, they represent the dark side of our swiftly electrifying world.

Lithium represents a route out of our reliance on fossil fuel production. As the lightest known metal on the planet, it is now widely used in electric devices from mobile phones and laptops, to cars and aircraft.

Lithium-ion batteries are most famous for powering electric vehicles, which are set to account for up to 60 per cent of new car sales by 2030. The battery of a Tesla Model S, for example, uses around 12 kg of lithium.

These batteries are the key to lightweight, rechargeable power. As it stands, demand for lithium is unprecedented and many say it is crucial in order to transition to renewables.

However, this doesn't come without a cost - mining the chemical element can be harmful to the environment.

German aerial photographer Tom Hegen specialises in documenting the traces we leave on the earth's surface. His work provides an overview of places where we extract, refine and consume resources with his latest series exposing the “Lithium Triangle.”

This region rich with natural deposits can be found where the borders of Chile, Argentina and Bolivia meet. And roughly a quarter is stored in the Salar de Atacama salt flats in northern Chile.

Hegen spoke to us about the project.

“Since a lot of my work deals with the extraction, processing and use of resources, I got interested in what the transition of the mobility sector towards electromobility looked like,” he begins.

“Lithium is one of the key components of building (car) batteries and I wanted to photograph the worldwide biggest examples of lithium evaporation sites in the lithium triangle of Chile, Bolivia and Argentina.”

So how did he do it?

“To get the enormous mining operations in the frame, I chartered a small aeroplane and flew high above them,” Hegen explains.

His images of the Soquimich lithium mine in the Atacama desert, run by leading mining operator Sociedad Química y Minera (SQM), are part of his new project, The Lithium Series I.

Why are the fields so colourful?

The vivid hues of the lithium fields, or ponds, are caused by different concentrations of lithium carbonate. Their colours can range from a pinky white, to a turquoise, to a highly concentrated, canary yellow.

A 2015 piece in the New Scientist described the fields as “surreal landscapes where batteries are born”. read  (much larger) whole article - euronews.green - link - the always brilliant Maeve Campbell - link - more like this (lithium) - link - more like this (Chile) - link
