Abstract: Techno-economic System Analysis of Alternative Power Trains for Non-road Mobile Machinery Serhiy Kapustyan,a Thomas Grube,a Jochen Linssen,a and Detlef Stolten a,baForschungszentrum Jülich GmbH, Institute of Energy and Climate Research – Jülich Systems Analysis (ICE-2) , 52425 Jülich, GermanybRWTH Aachen University, Chair for Fuel Cells, Faculty of Mechanical Engineering, 52062 Aachen, GermanyAbstractThis study provides a comparative techno-economic systems analysis of different powertrain and fuel options with associated infrastructure for non-road mobile machinery and compares them with conventional diesel systems.First, the comprehensive framework required for a complete techno-economic analysis of different powertrain options for non-road mobile machinery is presented. The model includes a load profile generator designed for various machines used in sectors such as construction and agriculture. The load profile generator determines power output based on force calculations at the cylinders and transmissions, as well as the sizing of various powertrain components. Models for calculating energy demand based on the power output of the load profile generator are integrated into the framework. These models account for systems efficiencies that depend on various components such as the fuel cell stack, battery, and both electrical and internal combustion engine s. In addition, the framework includes infrastructure options for both fuel cell and battery electric vehicles.The economic evaluation is based on total cost of ownership calculations that include machine costs, fuel costs, and the costs of conventional and alternative powertrain components. It also includes infrastructure costs for battery charging stations and hydrogen refueling components such as compressors, on-site tanks, dispensers, and balance-of-plant equipment.A scenario-based analysis is then conducted to assess the sensitivity of operating parameters for non-road mobile machinery. The evaluation focuses on factors such as hydrogen refueling time, residual charge in the hydrogen tank, and fleet size to understand their impact on total cost of ownership over different years. By varying these parameters, the analysis provides insight into how operating conditions affect the economics of non-road mobile machinery technologies under different future scenarios.This economic assessment, based on total cost of ownership calculations, serves as a means of accessing the competitiveness of alternative technologies in the non-road mobile machinery sector and contributes to an informed decision-making process. This analysis can be applied at a national level as well as for individual companies or sites. At the national level, it can serve as a tool to identify pathways to cost-effective solutions across different non-road mobile machinery sectors and their respective powertrain options.
