“…In the context of powertrain electrification, scientific research have recently been done increasingly for different types of NRMM. Typically, these research studies focus on specific vehicular applications e.g., on construction machines [5,26], mining vehicles and equipment [22,27,28], port equipment (different types of carriers) [29,30], and agricultural tractors and machinery [31][32][33].…”

Powertrain electrification continues to be a growing trend in vehicular applications. Electric powertrains have numerous advantages over traditional mechanical and hydraulic powertrains but there are still important challenges to overcome for long-term commercial success. This research presents a technological assessment of present and future developments of powertrain electrification in non-road mobile machinery (NRMM). The challenges and opportunities of NRMM electrification are described in detail. The trends and drivers related to technological development such as regulations, policies and market development are analyzed, and technology enablers are highlighted. Future scenarios are formulated based on the prevailing trends and drivers, development of key components, scientific literature and status of the non-road mobile machinery industry. Some recommendations are also given in relation to the development of hybrid and electric powertrains for NRMM. The key findings of this research indicate that the electrification of NRMM is slowly started and the progress is demonstrated by hybridization of some specific, successful mobile machines. In short-term, high component and technology development costs remain the main barrier for higher adoption of electric and hybrid powertrains. In the long-term scenario, many NRMM can operate autonomously and powertrain electrification has become mainstream technology.

“…Figure 3 presents recently developed hybrid mobile machines. A powertrain that has a fuel cell stack as primary energy and power source and a battery as energy storage is also a hybrid powertrain [29]. Fuel cells are still in development phase and first full size fuel cell hybrid vehicles are now entering the markets.…”

“…However, hybrid powertrains featuring the presence of an internal combustion engine still produce several harmful pollutants in the exhaust. To overcome this limit, an alternative solution for the electrification of the sector of NRMM is represented by fuel cell powertrains [22][23][24][25][26][27][28]. Fuel cell hybrid electric powertrains have gained attention due to their characteristics that combine the advantage of having approximately zero local emissions with high endurance and low refuelling time [29].…”

The growing awareness about climate change and environmental pollution is pushing the industrial and academic world to investigate more sustainable solutions to reduce the impact of anthropic activities. As a consequence, a process of electrification is involving all kind of vehicles with a view to gradually substitute traditional powertrains that emit several pollutants in the exhaust due to the combustion process. In this context, fuel cell powertrains are a more promising strategy, with respect to battery electric alternatives where productivity and endurance are crucial. It is important to replace internal combustion engines in those vehicles, such as the those in the sector of Non-Road Mobile Machinery. In the present paper, a preliminary analysis of a fuel cell powertrain for a telehandler is proposed. The analysis focused on performance, fuel economy, durability, applicability and environmental impact of the vehicle. Numerical models were built in MATLAB/Simulink and a simple power follower strategy was developed with the aim of reducing components degradation and to guarantee a charge sustaining operation. Simulations were carried out regarding both peak power conditions and a typical real work scenario. The simulations’ results showed that the fuel cell powertrain was able to achieve almost the same performances without excessive stress on its components. Indeed, a degradation analysis was conducted, showing that the fuel cell system can achieve satisfactory durability. Moreover, a Well-to-Wheel approach was adopted to evaluate the benefits, in terms of greenhouse gases, of adopting the fuel cell system. The results of the analysis demonstrated that, even if considering grey hydrogen to feed the fuel cell system, the proposed powertrain can reduce the equivalent CO2 emissions of 69%. This reduction can be further enhanced using hydrogen from cleaner production processes. The proposed preliminary analysis demonstrated that fuel cell powertrains can be a feasible solution to substitute traditional systems on off-road vehicles, even if a higher investment cost might be required.

“…The technology is mature enough but the downside is that the manufacturing costs of fuel cells are still on a quite high level. In short and medium term, it is expected that fuel cell hybrid systems will be adopted in limited, special applications in which the advantages of the fuel cell technology can be exploited in favour of cost-effectiveness [2,8].…”

Electrification of non-road mobile machinery (NRMM) is a growing trend. This paper highlights the potential of electric and hybrid powertrains in different NRMM sectors and elaborates the factors that may hinder the development. The NRMM sectors, the vehicle types, their operation and duty cycles and market shares are described. Comparison between the typical duty cycles and operation of on-road and off-road vehicles is performed in order to gain insight into the specific features of off-road vehicles. The development of NRMM is subject to various drivers that range from customer needs to fuel and energy prices and rules and legislation.The main results of our study are 1) a review of the present status and analysis of the future trends and potential of electrification and hybridization of NRMM and, 2) propositions for overcoming the challenges that are related to the electrification and hybridization of NRMM.
