Special Issue Information

Dear Colleagues,

We would like to invite publications for this Special Issue of Energies titled “Sustainable energy systems for heavy-duty mobile and maritime applications”. There is a strong need to drive decarbonization in the transportation and mobile machinery sectors, which account for ~16% of global GHG emissions, and ~25% of EU and ~29% of US GHG emissions, respectively. Of particular significance are maritime, heavy-duty off-road, and commercial on-highway applications, where battery-only electrification is difficult due to space, weight, and duty cycle requirements. A combination of highly efficient chemical energy converters, appropriate degrees of hybridization, renewable/carbon-neutral fuels, and advanced control strategies are needed to minimize the overall carbon footprint of these applications. The enforcement of stringent criteria pollutant emission regulations and the presence of electric charging infrastructure will also play a key role in influencing the design and operation of the powertrains/energy systems for these applications.

This Special Issue aims to capture recent technical advances towards improving the sustainability of these applications. Research involving modelling, simulation, experimental implementation, and/or field demonstration are encouraged. Topics of interest include but are not limited to the following areas, applied to maritime, off-road, and on-highway applications.

  • Internal combustion engine (ICE) and fuel cell (FC) technology;
  • Electric and hydraulic hybridization;
  • Dynamic modelling and simulation of ICEs, FCs, and system energy flows;
  • Transient control strategies;
  • Waste heat recovery systems;
  • Hybrid powertrain component sizing and energy management ;
  • Strategies for emissions reduction;
  • Alternate fuels and enabling fuel flexibility with ICEs and FCs;
  • Onboard power electronics (DC grids, fast chargers, overhead/wireless charging, etc.);
  • Experimental demonstration over steady state and dynamic conditions;
  • Life cycle assessments.

We look forward to receiving publications on one or more of these topics.

The International Maritime Organization (IMO) established new strategies that could lead to a significant reduction in the carbon footprint of the shipping sector to address global warming. A major factor in achieving this goal is transitioning to renewable fuels. This implies a challenge, as not only ship-innovative solutions but also a complete low-carbon fuel supply chain must be implemented. This work provides a method enabling the exploration of the potential of low-carbon fuel technologies for specific shipping routes up to larger sea regions. Several aspects including vessel sizes, impact of weather and shipping routes, emissions savings and costs are considered. The local energy use is determined with proven bottom-up prediction methods based on ship positioning data from the Automatic Identification System (AIS) in combination with weather and ship technical data. This methodology was extended by an approach to the generation of a basic low-carbon fuel system topology that enables the consideration of local demand profiles. The applicability of the proposed approach is discussed at hand via a case study on Roll-on/Roll-off passenger and cargo (RoPax) ferries transitioning from conventional fuels to a compressed hydrogen fuel system. The results indicate a potential reduction in emissions by up to 95% and possible system sizes and costs. Full article

Shipping accounts for about 3% of global CO2 emissions. In order to achieve the target set by the Paris Agreement, IMO introduced their GHG strategy. This strategy envisages 50% emission reduction from international shipping by 2050, compared with 2008. This target cannot be fulfilled if conventional fuels are used. Amongst others, hydrogen is considered to be one of the strong candidates as a zero-emissions fuel. Yet, concerns around the safety of its storage and usage have been formulated and need to be addressed. “Safety”, in this article, is defined as the control of recognized hazards to achieve an acceptable level of risk. This article aims to propose a new way of comparing two systems with regard to their safety. Since safety cannot be directly measured, fuzzy set theory is used to compare linguistic terms such as “safer”. This method is proposed to be used during the alternative design approach. This approach is necessary for deviations from IMO rules, for example, when hydrogen should be used in shipping. Additionally, the properties of hydrogen that can pose a hazard, such as its wide flammability range, are identified. Full article
