Minerals from the seabed

Concept

  • Roughly 25% of the ocean floor is covered with manganese nodules.
  • These nodules contain manganese, cobalt, copper, and nickel.
  • Extracting these nodules is technically difficult and environmentally harmful as it stirs up sediment, killing marine life.

Real-world Example

  • Countries like China, France, Germany, India, Japan, Russia, and South Korea have been granted licenses to explore deep-sea mining by the International Seabed Authority.
  • Canadian company Nautilus Minerals aims to be the first to mine deep-water, targeting copper and gold deposits in the Bismarck Sea north of Papua New Guinea.

Hydrates - a potential energy source

Concept

  • Hydrates are compounds of methane molecules trapped in a water cage, found in permafrost and deep ocean shelves.
  • They potentially hold more energy than all known fossil fuel deposits.
  • The extraction process is challenging and risky due to the presence of methane, a potent greenhouse gas.

Real-world Example

  • Japan and India, with limited oil and gas resources, are highly interested in this potential energy source.
