While we know the extensive use of Niobium such as MRI, Maglev Trains, Stainless Steel, High Strength Low Alloy Steel, Jet Engines, etc, etc, here is another future use which could very well become reality in the not too distant future: Batteries.
Both Niobium and Titanium oxides could be used to replace the anode material in batteries. The world will need astronomical amounts of Lithium, Niobium and Titanium oxides to move to cleaner climate.

“Using Niobium Titanium Oxide (NTO) as a next-generation anode material”

Toshiba have been focusing our attention on the possibility of Niobium Titanium Oxide (NTO) as a next-generation anode material that will help increase the battery capacity while maintaining the excellent characteristics of lithium titanium oxide (LTO), the conventional anode material of SCiB™. NTO has roughly three times higher theoretical volume capacity density than LTO while providing the advantages of LTO such as long life and rapid charging.
