The Challenge

Boats, mining and construction vehicles, tractors, railcars: these are only a few of the many possible applications for electrification and hybridization. They all face the same challenges, such as the urgency to reduce emissions, the necessity to find an alternative to oil due to price volatility, and the need to reduce their operating costs.
