Mining
The continuous usage of extremely heavy trucks in Mining plays to 2 strength of iOLS. The more movement ant the higher the weight the more electric power is generated.
Exploratory projects for e trucks show limitations in use that could be addressed with iOLS.

For the intermediate solutions like diesel-electric drive hybrids iOLS is ideal to significantly reduce the share of diesel combustion and therefore immediately improves the carbon footprint and cost efficiency in Mining operations.
