Vacuuming Battery Minerals From The Sea Bed

We don’t disagree for a moment the world is entering a phase of climate and political turmoil. This means we have to be nimble, fleet of foot, and innovative. But we can’t keep following the old ways and ravaging the environment either. We learned this morning big money is investigating vacuuming battery minerals from the sea bed. The news broke when the World Wildlife Fund (WWF)director general called for strict regulation.

Vacuuming The Sea Bed for Battery Minerals

Deep-sea mining involves using heavy machinery to suck potato-sized rocks or nodules off the ocean floor. Targets include those containing “cobalt, manganese, and other rare metals mostly used in batteries” according to Daily Maverick.

“Have we nor learned our lesson,”  WWF’s Marco Lambertini asked assembled media representatives. “We simply don’t know what we will unleash by going down hundreds, thousands of meters to the bottom of oceans.” He described to Reuters later how this could potentially generate damaging sediment plumes and affect fish migration.

We agree with Lambertini’s measured approach of rather recycling vast piles of e-waste heading for landfill in many countries. However, those returns are unfortunately lower than tapping into virgin resources, and so there will be deep sea mining takers.

How Do We Control This Situation Worsening?

World Wildlife Fund is calling for a global moratorium on all deep-sea mining activities. Endangered nations including Palau and Fiji are supporting this. However, Daily Maverick says UN International Seabed Authority (ISA) is drawing up regulations governing mining in the high seas.

This step would bring an end to the global ban on deep-sea mining. However, we do know many nations will support this idea, for they are keen to exploit the undeniable richness. We need to shift to alternative energy storage instead, using less-expensive more abundant materials.

About Author

I have been writing about batteries and energy storage for more than ten years, and have published over 4,000 articles on this website. During that time, I have researched developments across lead-acid, lithium-ion, sodium-ion, flow batteries, and emerging energy-storage technologies. My goal is to explain complex battery concepts in clear, practical language that anyone can understand. My writing career began unexpectedly after leaving the corporate world. What started as a search for a new direction gradually became a fascination with batteries, renewable energy, and the science that powers modern life. Writing may not have made me wealthy, but it has given me the opportunity to explore an industry that continues to evolve in remarkable ways.
