Special Issue Information

Dear Colleagues,

With the term Non-Road Mobile Machinery (also known as NRMM) it is usual to address a wide range of off-road vehicles used for work activities in the following areas: construction, agriculture, forestry, handling, rail transports, maritime and waterway navigation, public green maintenance, etc. The need for lower Greenhouse gas and pollutant emissions is driving both the academia and the industry towards new powertrain and vehicle design solutions with the aim of obtaining higher efficiency for the same work tasks. This result can be achieved improving the powertrain layout and components, using alternative fuels with lower environmental impact, or adopting electric systems for full or hybrid electric configurations. Environmental sustainability should become the driving factor for innovative design of new powertrains, with a wider look at all the different phases of the product life cycle. Moreover, diagnostics and predictive maintenance should be considered as essential tools to preserve as much as possible the initial powertrain efficiency during the whole service life.

This Special Issue aims to gather contributions from experts in the field of NRMM devoted to the pursuit of efficiency improvements at powertrain or system level. Topics of interest for publication include, but are not limited to:

  • Design, modelling, control and optimization of Hybrid, Electric and Fuel Cell powertrain systems;
  • Energy management strategies for Hybrid, Electric and Fuel Cell powertrain systems;
  • Hardware In the Loop testing for Hybrid, Electric and Fuel Cell powertrain systems;
  • Alternative fuels for internal combustion engines;
  • Design, modelling, control and optimization of power-split and CVT powertrain systems;
  • Design, modelling, control and optimization of hydrostatic, hydraulic and electro-hydraulic powertrain systems;
  • Circular design and environmental impact of innovative vehicle and powertrain components;
  • Diagnostic and predictive maintenance for powertrain efficiency optimization during vehicle service life.

Future transport systems will rely on new electrified drives utilizing batteries and hydrogen-powered fuel cells or combustion engines with sustainable fuels. These systems must complement each other and should not be viewed as competing. Properties such as efficiency, range, as well as transport and storage properties will determine their use cases. This article looks at the usability of liquid electro-fuels in freight transport and analyzes the production capacities that will be necessary through 2050 in Germany. Different scenarios with varying market shares of electro-fuels are considered. A scenario with a focus on fuel cells foresees a quantity of 220 PJ of electro-fuels, i.e., 5.1 million tons, which reduces 80% of carbon dioxide emissions in LDV and HDV transport. A further scenario achieves carbon-neutrality and leads to a demand for nearly 17 million tons of e-fuel, corresponding to 640 PJ. Considering a final production rate of 5.1 million tons of electro-fuels per year leads to maximum investment costs of around EUR 350 million/year in 2036 during the ramp-up phase. The total investment costs for synthesis plants amount to EUR 4.02 billion. A carbon-neutrality scenario requires more than a factor 3 for investment for the production facilities of electro-fuels alone. Full article

In recent years, growing awareness about environmental issues is pushing humankind to explore innovative technologies to reduce the anthropogenic sources of pollutants. Among these sources, internal combustion engines in non-road mobile machinery (NRMM), such as agricultural tractors, are one of the most important. The aim of this work is to explore the possibility of replacing the conventional diesel engine with an electric powertrain powered by a hybrid storage system, consisting of a small battery pack and a fuel-cell system. The battery pack (BP) is necessary to help the fuel cell manage sudden peaks in power demands. Numerical models of the conventional powertrain and a fuel-cell tractor were carried out. To compare the two powertrains, work cycles derived from data collected during real operative conditions were exploited and simulated. For the fuel-cell tractor, a control strategy to split the electric power between the battery pack and the fuel cell was explored. The powertrains were compared in terms of greenhouse gas emissions (GHG) according to well-to-wheel (WTW) equivalent CO2 emission factors available in the literature. Considering the actual state-of-the-art hydrogen production methods, the simulation results showed that the fuel-cell/battery powertrain was able to accomplish the tasks with a reduction of about 50% of the equivalent CO2 emissions compared to traditional diesel-powered vehicles.
