The spiralling environmental cost of our lithium battery addiction

As the world scrambles to replace fossil fuels with clean energy, the environmental impact of finding all the lithium required could become a major issue in its own right

Here’s a thoroughly modern riddle: what links the battery in your smartphone with a dead yak floating down a Tibetan river? The answer is lithium – the reactive alkali metal that powers our phones, tablets, laptops and electric cars.

In May 2016, hundreds of protestors threw dead fish onto the streets of Tagong, a town on the eastern edge of the Tibetan plateau. They had plucked them from the waters of the Liqi river, where a toxic chemical leak from the Ganzizhou Rongda Lithium mine had wreaked havoc with the local ecosystem.

There are pictures of masses of dead fish on the surface of the stream. Some eyewitnesses reported seeing cow and yak carcasses floating downstream, dead from drinking contaminated water. It was the third such incident in the space of seven years in an area which has seen a sharp rise in mining activity, including operations run by BYD, the world’ biggest supplier of lithium-ion batteries for smartphones and electric cars. After the second incident, in 2013, officials closed the mine, but when it reopened in April 2016, the fish started dying again.

They are aiming for the brine underneath swathes of magnesium and potassium in the hope of finding lithium-rich spots. Since the 2000s, most of the world’s lithium has been extracted this way, rather than using mineral ore sources such as spodumene, petalite and lepidolite. Matjaž Krivic/INSTITUTE

Lithium-ion batteries are a crucial component of efforts to clean up the planet. The battery of a Tesla Model S has about 12 kilograms of lithium in it, while grid storage solutions that will help balance renewable energy would need much more.

Demand for lithium is increasing exponentially, and it doubled in price between 2016 and 2018. According to consultancy Cairn Energy Research Advisors, the lithium ion industry is expected to grow from 100 gigawatt hours (GWh) of annual production in 2017, to almost 800 GWhs in 2027.

William Adams, head of research at Metal Bulletin, says the current spike in demand can be traced back to 2015, when the Chinese government announced a huge push towards electric vehicles in its 13th Five Year Plan. That has led to a massive rise in the number of projects to extract lithium, and there are “hundreds more in the pipeline,” says Adams.

But there’s a problem. As the world scrambles to replace fossil fuels with clean energy, the environmental impact of finding all the lithium required to enable that transformation could become a serious issue in its own right. “One of the biggest environmental problems caused by our endless hunger for the latest and smartest devices is a growing mineral crisis, particularly those needed to make our batteries,” says Christina Valimaki an analyst at Elsevier.

Alberta Can Transition from Oil and Gas and Have a Strong Economy. Here’s How

‘Tens of thousands’ of people would be put to work immediately in high-skill jobs, say advocates.

What will a transition away from oil and gas mean for workers in Alberta?

Perhaps greater job security than in the boom and bust heydays of the oilsands, comparable wages and less time apart from family.

This is not a utopian pipe dream. Over the past month The Tyee spoke with experts across the province and the country who said Albertans have the skills and desire to build the sustainable energy system necessary to address our climate emergency.

“A lot of the people that support the pipeline are also very pro-renewable energy,” said Lliam Hildebrand, who spent years working in the oilsands and now runs a group called Iron & Earth that advocates for policies connecting oil workers to the millions of jobs required to build a low-carbon economy in Canada.

Decades of employment for laid-off Albertans could be unlocked by our political leaders in a matter of days.
