Lithium is an alkali metal that is important for renewable energy. Lithium ion batteries are the best type of battery for cars and solar storage because they last a long time and are very efficient.
Lithium is an important resource that is used in many products, like laptops and cell phones, as well as electric car batteries. Even though the United States has a lot of lithium reserves, it doesn't have any mines that are currently in operation. This is because there are several reasons why new mines are being put on hold. These reasons include cheaper import options and local opposition.
Key takeaways
- Lithium is necessary for renewable grids as it is the key element that powers lithium-ion storage batteries.
- Lithium mining used to involve a lot of groundwater, taking up a lot of land, and emitting carbon dioxide during the mining process.
- Geothermal heat plants are the best option because the water that is used to power them can be used again as a source of lithium.
Where is lithium found in the U.S.?
There are different ways to mine lithium. The traditional way is to get it from rocks and water that is rich in lithium. Another way is to use water that is a byproduct of geothermal energy plants. This can solve two problems at once by creating emissions-free geothermal energy and using the lithium at the same time.
Lithium is a common element that can be found in many places in the United States, as well as all over the world. However, mining for lithium can be difficult because it requires special methods and equipment that can sometimes lead to pollution and take up a lot of space - two main reasons why some people don't like mines.
Where are there lithium mines in the U.S.?
Lithium is a mineral that can be found all over the United States. However, the only operating mine in the country is in Nevada. This mine uses a method called brine extraction to take lithium deposits from under the surface of the earth. The brine is usually found below the surface of dry lake beds and typically in deserts.
There are plans to open more mines in Nevada, California, Arkansas, and North Carolina in order to reach the previously-stated goal of supplying lithium domestically and via strategic partners by 2030.
Why do we need more lithium mines in the U.S.?
It takes a long time for raw lithium or lithium-ion batteries to get to the United States. The U.S. usually gets its lithium from South America or Australia.
The mined lithium is usually processed and turned into batteries in China. That's two more continents the lithium has to go through before it's finished as a battery. Plus, emissions are released when shipping the lithium between countries.
The United States wants to increase the domestic production of lithium so that there will not be any long wait times or price increases in the future. Some people are not happy with this idea because they are afraid of the pollution that the mines might cause, as well as the pushback from native tribes whose sacred land would be affected.
How is lithium mined and why is it controversial?
Mining lithium has a negative effect on the environment. This is because it takes up a lot of land, uses a lot of water, and releases harmful emissions during the mining process. Additionally, these mines can take up a lot of space, extract a lot of soil, or need space for water to evaporate. The two traditional methods mentioned earlier, rock and brine extraction, need groundwater to operate the mines. Using this water can leave it polluted while also leaving less water for local communities and natural environments.
Lithium mines use fossil fuels to power their equipment. This causes greenhouse gasses to be emitted. People are protesting the existence of these mines because of the environmental impacts.
The environmental concerns are valid, but it is also true that lithium is a key element needed for the renewable energy transition that is necessary to mitigate global warming.
As mentioned earlier, extracting brine from geothermal heat plants is a good option because the geothermal plants create energy and have the smallest environmental impact. This lithium mining process uses less water, less land, and emits zero carbon emissions compared to rock and underground reservoir mining.
Why is lithium important for the energy transition?
Lithium is a key component of lithium-ion batteries, which are the best batteries for recharging and powering technology we use in our daily lives, like cell phones, laptops, electric vehicles, and rechargeable storage batteries.
Batteries are going to be extremely important as the world moves towards renewable energy. Since the sun does not always shine and the wind does not always blow, we will need batteries to store energy for when production is low.
There can be an energy imbalance during the sunniest parts of the day when energy might not be used the most. Lithium-ion batteries will be able to store excess energy that can then be utilized when renewable sources are not producing enough electricity for everyone to use.
Obviously, for lithium-ion batteries to work, we need lithium.
Are there alternatives to lithium mining?
At the moment, the only way to get lithium is through traditional mining methods. If we don't mine it, we won't have a chance at building the battery storage required to keep our grid fossil fuel-free. Mining seems like the lesser of two evils, but fortunately, scientists are working on other ways to get lithium, such as recycling it.
Lithium has been used in electronics for a long time. When the electronics reach the end of their life, people often throw them out. The old recycling methods use a lot of energy and acid to break down the parts of the batteries that people don't want. But new methods are being developed that use less energy and can even make the recycled batteries work better than before. Recycling lithium is not as good as getting it from mines yet, but it could be in the future if we do it on a large scale.
The truth is that recycling is not enough to help the environment. We also need to find alternative energy sources, and that includes mining for lithium.
