Electric vehicles challenged

There's a "dirty secret" behind EVs that many people are unaware of.

Electric vehicles (EVs) are on the rise, with more people making the switch from traditional petrol and diesel-powered cars. However, there's a "dirty secret" behind EVs that many people are unaware of. In this article, we explore the challenges and solutions to making EVs a truly green option for sustainable transportation.

One of the most significant issues with EVs is the source of the electricity they use. While EVs produce zero emissions, the power plants that generate the electricity they run on often rely on fossil fuels like coal and natural gas. This means that EVs are not entirely emission-free and can be just as polluting as traditional cars in some cases.

To address this, some car manufacturers are investing in renewable energy to power their EVs, further reducing their carbon footprint. For instance, car manufacturer Volkswagen is planning to transition its production to solely produce electric vehicles and become carbon neutral by 2050. With plans to build roughly 26 million vehicles on its electric platforms in the next 10 years.

Another major challenge facing EVs is the production and disposal of EV batteries. The manufacturing process of EV batteries can have a significant carbon footprint due to the energy-intensive process and the use of materials like lithium, nickel and cobalt, which can have negative social and environmental impacts.

However, recycling and reusing EV batteries can significantly reduce the carbon footprint of these technologies. For instance, companies such as Redwood Materials and American Battery Technology Company (ABTC) are investing in battery recycling to reduce waste and create a more sustainable supply chain for EVs. In Canada, Li-Cycle is another company that recovers critical materials like lithium, cobalt, and nickel from end-of-life batteries, making them available for reuse in the manufacturing of new batteries.

In the European Union, there is an effort to increase battery recycling. In 2019, only 51% of portable batteries sold in the EU were collected for recycling. However, the EU is introducing new rules with more stringent targets for battery collection, such as 45% by 2023, 63% by 2027, and 73% by 2030 for portable batteries, and 51% by 2028 and 61% by 2031 for batteries used in light means of transport.

The new rules also require the reuse of minimum levels of recovered cobalt (16%), lead (85%), lithium (6%), and nickel (6%) from both manufacturing and consumer waste in new batteries. These measures aim to improve battery recycling rates and promote sustainable battery production and consumption.

Additionally, some companies are exploring alternative battery technologies that do not rely on scarce or environmentally harmful materials. For instance, solid-state batteries use a solid electrolyte instead of a liquid one, making them potentially safer and more energy-dense than traditional lithium-ion batteries.

Moreover, the growth of the EV market also creates opportunities for new business models, such as vehicle-to-grid (V2G) technology. This technology allows EVs to provide energy back to the grid during peak demand periods, creating a more efficient and sustainable energy system.

Several companies are exploring this technology, including Nissan and BMW, which have already launched V2G pilot programs. This technology has the potential to significantly reduce the need for fossil fuel power plants and make the electricity grid more sustainable.

Overall, making EVs more sustainable requires a combination of factors. Adopting renewable energy sources, developing more sustainable battery technologies, and implementing effective recycling and reuse systems are all critical steps toward creating a greener future for transportation.

As technology continues to evolve, we can expect to see more innovative solutions emerging to make EVs more accessible and environmentally friendly. By addressing the challenges head-on and working together, we can make EVs a truly green option for sustainable transportation. The transition to EVs and sustainable energy systems will take time, but it's a necessary step towards a greener future for all.
