rare earths

By Jonathan Neale - The Ecologist, February 17, 2021

The failure of the electricity grid in Texas, USA, and the rolling blackouts in the Midwest, are one more consequence of climate breakdown.

The root problem is that the Arctic is growing warmer. As it does so, paradoxically, there is less of a barrier preventing very cold weather in the far north from moving south. This extremely cold weather then blankets cities and downs where people live.

The electricity grid in Texas simply cannot supply enough power for all the extra demands on heating. This is a problem what will grow much worse, and not just in Texas.

Complexity

But Fox News and the Governor of Texas are blaming the failure of the grid on the Green New Deal and renewable energy. That’s silly.

There is no Green New Deal in Texas. There are some wind turbines, that have apparently frozen. But the wind turbines in Canada and Antarctica have not frozen.

This is a problem caused by fossil fuels and privatized energy, not wind trubines.

But environmentalists have to be careful here, and we have to be up to speed on the full complexity of what a Green New Deal will mean for electricity grids.

That’s why The Ecologist is posting here the chapter on supergrids from my new book, Fight the Fire: Green New Deals and Global Climate Jobs.

Power

In what follows, I explain the difficulties in integrating 100 percent renewable energy into the grid, and how it can be done. I also show why that will be impossible if renewable energy and electricity supply are owned by private corporations.

The chapter is about supergrids around the world, but many of the examples come from the United States.

A rewired world does not mean that all energy will come from renewables. But it does mean that most energy will come from electricity, and all that electricity will come from renewables.

That will not be an easy thing to construct. We will need new national and international supergrids to integrate all these new kinds of power into new electrical supply systems. These will be qualitatively new undertakings.

The challenge of mixing together power from renewable energy is different in kind from mixing together energy from fossil fuels – and far more complex.

I have spent the last year working on a book called Fight the Fire: Green New Deals and Global Climate Jobs. Most of it is about both the politics and the engineering of any possible transition that can avert catastrophic climate breakdown. One thing I had to think about long and hard was lithium and car batteries.

I often hear people say that we can’t cover the world with electric vehicles, because there simply is not enough lithium for batteries. In any case, they add, lithium production is toxic, and the only supplies are in the Global South. Moreover, so the story goes, there are not enough rare earth metals for wind turbines and all the other hardware we will need for renewable energy.

People often smile after they say those things, which is hard for me to understand, because it means eight billion people will go to hell.

So I went and found out about lithium batteries and the uses of rare earth. What I found out is that the transition will be possible, but neither the politics nor the engineering is simple. This article explains why. I start by describing the situation simply, and then add in some of the complexity.

Lithium is a metal used in almost all electric vehicle batteries today. About half of global production of lithium currently goes to electric vehicles. And in future we will need to increase the production of electric vehicles from hundreds or thousands to hundreds of millions. That will require vast amounts of lithium.

There are three ways to mine lithium. It can be extracted from rock. It can be extracted from the brine that is left over when sea water passes through a desalination plant. Or it can be extracted from those brine deposits which are particularly rich in lithium. These brine deposits are the common way of mining lithium currently, because it is by far the cheapest. Most of the known deposits of lithium rich brine are in the arid highlands where Bolivia, Chile and Argentina come together.

Lithium mining is well established in Chile and Argentina. In both countries the local indigenous people have organized against the mining, but so far been unable to stop it. The mining is toxic, because large amounts of acid are used in the processing. But the mining also uses large amounts of water in places that already has little enough moisture. The result is that ancestral homelands become unlivable.

Bolivia may have even richer deposits of lithium than Argentina and Chile, but mining has not begun there. The Bolivian government had been led by the indigenous socialist Evo Morales from 2006 to 2019. Morales had been propelled to power by a mass movement committed to taking back control of Bolivia’s water, gas and oil resources from multinational corporations. Morales was unable to nationalize the corporations, but he did insist on the government getting a much larger share of the oil and gas revenue.[1]

His government planned to go even further with lithium. Morales wanted to mine the lithium in Bolivia, but he wanted to build factories alongside the mines to make batteries. In a world increasingly hungry for batteries, that could have turned Bolivia into an industrial nation, not just a place to exploit resources.

The Morales government, however, was unable to raise the necessary investment funds. Global capital, Tesla, the big banks and the World Bank had no intention of supporting such a project. And if they had, they would not have done so in conjunction with a socialist like Morales. Then, in 2019, a coup led by Bolivian capitalists, and supported by the United States, removed Morales. Widespread popular unrest forced a new election in October. Morales’ party, the Movement for Socialism won, though Morales himself was out of the running. It is unclear what will happen to the lithium.

That’s one level of complexity. The local indigenous people did not want the lithium mined. The socialist government did not want extractavism, but they did want industrial development.

Those are not the only choices.

For one thing, there are other, more expensive ways of mining lithium. It can be mined from hard rock in China or the United States. More important, batteries do not have to be made out of lithium. Cars had used batteries for almost a century before Sony developed a commercial lithium-ion battery in 1991. Engineers in many universities are experimenting with a range of other materials for building batteries. But even without looking to the future, it would be possible to build batteries in the ways they used to be built. Indeed, in January 2020, the US Geological Service listed the metals that could be substituted for lithium in battery anodes as calcium, magnesium, mercury and zinc.[2]

The reason all manufacturers currently use lithium is that it provides a lighter battery that lasts longer. That gives the car greater range without recharging, and it make possible a much lighter car. In other words, lithium batteries are cheaper.

Several articles and reports published recently have re-visited the question: how “clean” is “clean energy”? Here is a selection, beginning in October 2020 with a multi-part series titled Recycling Clean Energy Technologies , from the Union of Concerned Scientists. It includes: “Wind Turbine blades don’t have to end up in landfill”; “Cracking the code on recycling energy storage batteries“; and “Solar Panel Recycling: Let’s Make It Happen” .

“The glaring problem with Canada’s solar sector and how to fix it” (National Observer, Nov. 2020) states that “While solar is heralded as a clean, green source of renewable energy, this is only true if the panels are manufactured sustainably and can be recycled and kept out of landfills.” Yet right now, Canada has no capacity to recycle the 350 tonnes of solar pv waste produced in 2016 alone, let alone the 650,000 tonnes Canada is expected to produce by 2050. The author points the finger of responsibility at Canadian provinces and territories, which are responsible for waste management and extended producer responsibility (EPR) regulations. A description of solar recycling and waste management systems in Europe and the U.S. points to better practices.

“No ‘green halo’ for renewables: First Solar, Veolia, others tackle wind and solar environmental impacts” appeared in Utility Drive (Dec. 14) as a “long read” discussion of progress to uphold environmental and health and safety standards in both the production and disposal of solar panels and wind turbine blades. The article points to examples of industry standards and third-party certification of consumer goods, such as The Green Electronics Council (GEC) and NSF International. The article also quotes experts such as University of California professor Dustin Mulvaney, author of Solar Power: Innovation, Sustainability, and Environmental Justice (2019) and numerous other articles which have tracked the environmental impact, and labour standards, of the solar energy industry.

Regarding the recycling of wind turbine blades: A press release on December 8 2020 describes a new agreement between GE Renewable Energy and Veolia, whereby Veolia will recycle blades removed from its U.S.-based onshore wind turbines by shredding them at a processing facility in Missouri, so that they can be used as a replacement for coal, sand and clay in cement manufacturing. A broader article appeared in Grist, “Today’s wind turbine blades could become tomorrow’s bridges” (Jan. 8 2021) which notes the GE- Veoli initiative and describes other emerging and creative ways to deal with blade waste, such as the Re-Wind project. Re-Wind is a partnership involving universities in the U.S., Ireland, and Northern Ireland who are engineering ways to repurpose the blades for electrical transmission towers, bridges, and more. The article also quotes a senior wind technology engineer at the National Renewable Energy Laboratory in the U.S. who is experimenting with production materials to find more recyclable materials from which to build wind turbine blades in the first place. He states: “Today, recyclability is something that is near the top of the list of concerns” for wind energy companies and blade manufacturers alike …. All of these companies are saying, ‘We need to change what we’re doing, number one because it’s the right thing to do, number two because regulations might be coming down the road. Number three, because we’re a green industry and we want to remain a green industry.’”

These are concerns also top of mind regarding the electric vehicle industry, where both production and recycling of batteries can be detrimental to the planet. The Battery Paradox: How the electric vehicle boom is draining communities and the planet is a December 2020 report by the Dutch Centre for Research on Multinational Corporations (SOMO). It reviews the social and environmental impacts of the whole battery value chain, (mining, production, and recycling) and the mining of key minerals used in Lithium-ion batteries (lithium, cobalt, nickel, graphite and manganese). The report concludes that standardization of battery cells, modules and packs would increase recycling rates and efficiency, but ultimately, “To relieve the pressure on the planet, …. any energy transition strategy should prioritize reducing demand for batteries and cars… Strategies proposed include ride-sharing, car-sharing and smaller vehicles.”

As I write, we are in the midst of a global pandemic which reveals every kind of cruelty and inequality. Worse is to come. We are entering into a global recession and mass unemployment. Looming beyond that is the threat of runaway climate change. But this is also a moment in history. It may be possible, now, to halt the onward rush of climate breakdown.
A door is opening. In every country in the world, a great debate is beginning. The question is, what can be done about the economy? In every country, one answer will be that the government must give vast sums of money to banks, hedge funds, oil companies, airlines, corporations and the rich. And that the government must pay for all this by cutting hospitals, education, welfare and pensions.

The other answer will be that we must spend vast sums of money to create new jobs, build a proper healthcare system, meet human needs and stop climate change.

Who do we rescue? Their banks and their corporations, or our people and our planet?

The answer in favour of helping people, not the rich, is called a “Green New Deal”. The idea of a Green New Deal has been around for a decade in many countries. But the decisive moment came in 2017, when Alexandria Ocasio-Cortez and Bernie Sanders in the United States decided to back a Green New Deal. That resonated widely. As we entered the pandemic, that idea was already there.

But those three little words, Green New Deal, can mean everything, anything and nothing. We want one particular kind of deal. The words need to mean something real and particular if the deal is to make a difference.

Growth of solar panels and their lifespans

Solar energy is converted into electricity primarily with photovoltaic (PV) panels (there is another technology, called concentrating solar power, or CSP, but it is less commonly used and not addressed here). PV panels are comprised of individuals cells linked together, forming various shapes and sizes based on the needs of the system. The panels themselves are made with semiconductor materials—generally silicon, but sometimes various rare metals—and generally covered in glass.

The cost of PV panels has declined dramatically in recent years while their efficiency has gone up. These trends are continuing, leading to rapid growth of the solar industry globally. Solar panels on average last 25-30 years (and maybe even longer); thus, solar installations occurring today can be expected to remain productive until the middle of this century.

The reliability and longevity of new panels means that the volume requiring recycling or disposal is currently low, except for very early generations of PV panels and small numbers that may get broken during the installation process or damaged in storms.

However, options for recycling and disposal need to be addressed as PV production continues to ramp up. And while the larger recycling need may not come for another decade, infrastructure and policy should be put in place now to accommodate future needs.

Lithium-ion batteries dominate the energy storage scene

Lithium-ion (Li-ion) batteries might be known to everyday consumers as the rechargeable batteries which power our cellphones, cameras, and even toothbrushes. Apart from storing energy for small devices, Li-ion batteries are now being used at a much larger scale to store energy for electric vehicles (EVs) and as storage for renewable energy systems like wind and especially solar.

Bloomberg New Energy Finance reports that prices for battery packs used in electric vehicles and energy storage systems have fallen 87% from 2010-2019, much faster than expected. As the prices have fallen, battery usage has risen.

So have the conversations on what can and should be done with Li-ion batteries when they reach the end-of-use stage. Here we will focus on recycling of lithium-ion batteries from energy storage systems, but for more information on increasing possibilities for second-life uses of EV batteries, see our former colleague Hanjiro Ambrose’s blog and podcast episode.

As a key energy storage technology, batteries are important for incorporating higher amounts of wind and solar power on the grid.

Wind turbines have increased in size and quantity to meet clean energy capacity demands

Modern wind power converts the kinetic (movement) energy from wind into mechanical energy. This happens through the turning of large fiberglass blades, which then spin a generator to produce electricity. Wind turbines, as they are known, can be located onshore or offshore.

Wind power is projected to continue growing across the US by 2050. The latest Wind Technologies Market Report prepared by Lawrence Berkeley National Laboratory found that wind energy prices are at all-time lows, and for 2019, 7.3 percent of utility-scale electricity generation in the US came from wind. In this blog post, we will examine land-based wind turbines and the recycling opportunities that exist but are not yet widely implemented for the turbine blades.
