Electric car boom could result in resource shortages and toxic waste, ocean floor may have the solution – report

Deep sea mining could be the solution to further environmental problems, new Canadian research has found.

The debate about the green credentials of electric cars has been reignited, with new research claiming a rise in electric vehicles could create a shortage in natural resources and further damage to the planet unless we find more sustainable ways to source the metals required to construct battery packs and wiring.
The new study, conducted by a coalition of Canadian researchers, says the transition away from fossil fuels is increasing demand for base metals, with shortages in nickel, cobalt and copper predicted to emerge as early as 2025.
The solution, it says, could lie in the deep sea mining of certain underwater rock concretions that can provide the materials used in electric car battery production without any of the toxic waste.
The study was commissioned by deep sea mining company DeepGreen, which has a vested interest in the proposed method.
According to the research, an electric car with a 75KWh battery and NMC 811 (nickel-manganese-cobalt) chemistry needs 56kg of nickel, 7kg of manganese, 7kg of cobalt and 85 kg of copper for electric wiring.
The problem is, the study claims, these land ores have limited yield and conventional land mining processes produce billions of tonnes of waste while leaking deadly toxins into soil and water.

Yes far better to leak the toxins into the oceans.
