Future Energy Technology for Nonroad Mobile Machines

Abstract

Greenhouse gases emissions reduction in the energy and transportation systems is extremely important. Nonroad mobile machines (NRMMs) are a key factor of production in many industrial and transportation systems with high-energy intensity. NRMM cover a wide range of application sectors and operate often in harsh environments. This study presents a literature review for NRMM on agriculture and forestry, mining and earth-moving, construction, and ports. It provides an overview of future energy technology and energy-related business factors for NRMM, considering different geographical areas, various energy sources, energy delivery solutions, and different types of powertrains. The best solutions for the case combinations and projected market environments are derived for several case regions. This study also contains a detailed example of an off-grid mining with renewable energy supply. The analysis of the off-grid mining cases clearly reveals the differences between the Nordic conditions and southern conditions. The importance of the wind power as a source for the renewable energy is emphasized in Nordic conditions, but the solar power can augment it during the summer months. Also, the seasonal storage becomes important in the case of Nordic conditions.
