ReplyDeleteNickel is an important metal used in several clean energy technologies, especially Electric Vehicles (EVs), and the demand for it is expected to surpass six million tonnes a year by 2040. While EVs are seen as a cleaner alternative to traditional fossil fuel-powered vehicles, there are hidden environmental costs associated with their production, especially in the manufacturing of lithium-ion batteries.
ReplyDeleteNickel powers everything, from gadgets to green technologies. But getting it currently involves a far from green, in fact, a dirty process. However, a new study has revealed what its authors have said is a game-changing and sustainable method to extract nickel from low-grade ores using hydrogen plasma instead of carbon. It’s a one-step process free of carbon dioxide that reportedly saves both energy and time.
ReplyDeleteA major component in these batteries is nickel and its extraction is highly carbon-intensive. Producing just one tonne of nickel can result in more than 20 tonnes of carbon dioxide emissions. So while EVs reduce emissions during operation, the process of sourcing materials like nickel simply shifts the pollution burden from the transportation sector to the mining and processing sector, among others.
