Electric car batteries could see a 90% carbon footprint reduction.

Electric car batteries could see a 90% carbon footprint reduction by getting the main​ minerals from deep-sea rocks.

T​he main criticism of electric cars is that, when making the batteries, one has to mine the necessary minerals from land ores and this process isn’t very kind to the environment but it was the only method of creating the batteries... until now.

Over the last few years, a lot of r​esearch has just been conducted and scientists have now come to the conclusion that electric car batteries could see a 90% carbon footprint reduction if deep-sea polymetallic nodules

W​hat on earth are polymetallic nodules?

I​f you’re not Walter White, you probably won’t have the faintest clue as to what polymetallic nodules are. But luckily, you’ve got a random 14 year old to help you!

P​olymetallic nodules sit on the top of the seabed. Close to 100% of polymetallic nodules are made up of usable minerals which is incredible when compared to the >1% that is found within ores found on land. The best thing is that these nodules can be collected without having to move or drill anything- it’s easy!

W​hy wasn’t this discovered earlier?

I​ think that, because of the sudden surge in demand for electric vehicle batteries, the world has now just been thrown into a whole new age of ideas and engineering.

T​his type of stuff wasn’t discovered 10 years ago because, well, nobody had to think about this issues then!

T​hanks for reading!

    Deep-sea mining could wreck the last unexplored ecosystem on Earth

    HAVING spent much of human history scouring – and scarring – Earth's surface to extract precious mineral resources, we are now turning to the most remote, and least known, part of our planet in search of more: the deep sea.

    This month, the Belgian dredging company DEME-GSR will send a prototype ore collector to the Pacific Ocean's Clarion-Clipperton Zone (CCZ), an area between Hawaii and Mexico. Here lies one of the world's largest untapped collections of rare minerals and metals, all neatly enveloped in trillions of potato-sized packages known as polymetallic nodules scattered across this vast stretch of seabed.

    The International Seabed Authority has granted 29 licences for contractors to explore mineral wealth at specific locations. Of those licences, 16 have been granted for the CCZ.

    Nobody knows the harm that deep-sea mining will do, in part because so little is known about the creatures that inhabit these places. Only now are scientists getting the opportunity to study them, often funded by the industry itself. Among the discoveries so far are otherworldly animals such as fast-moving sea urchins, the yellow, gelatinous "gummy squirrel" and a species of bacteria that can absorb vast quantities of carbon dioxide. To examine the effects of mining on such an ecosystem, the German research vessel RV Sonne will travel alongside the DEME-GSR ship while it tests its mining prototype.

    Many scientists see this kind of funding as an unparalleled opportunity to help write the rule book for an extractive industry before it gets going; a mining code outlining best practice is to be written by next year. But this month's trial will take place over just five days, hardly enough to say anything about the impacts of 30-year exploitation licences. If regulators are serious about developing evidence-based environmental standards for deep-sea mining, the industry needs to slow down.

    The UN has designated 2021 to 2030 as a Decade of Ocean Science for Sustainable Development, and what better question for it to address than how deep-sea mining can evolve in a sustainable way. Now that really would be striking gold.

    • Those are some brilliant points- I think you should put that in an article!

    • Why, others are working on it already. It is also not my area of environmental science. I just had to spend a year with them, hardcore bunch they are.

  • Right, we've ruined the whole Earth's ground, now it's the ocean.

    • I think that when looking at matters like this, you can’t think about whether it’s harmful or not because it is but, it’s a lot less harmful than what was going on before.

      I like to think of this current age as some sort of transition period...
