In this paper, an optimization algorithm based on a Mixed-Integer Linear Programming (MILP) solver is developed to determine the best energy generation solutions for marine applications. Environmentally sustainable systems (e.g., fuel cells and batteries), heat recovery devices (e.g., HRSG and Organic Rankine Cycles) and traditional power...

As the interest in hydrogen and PEM fuel cells is growing, it is crucial to define the best technology for fuel storage, especially in the transportation field. Metal hydrides show different benefits, including the possibility of thermally coupling the hydrogen storage and utilization systems: fuel cells require heat subtraction for ensuring...

In this paper, green hydrogen produced via water electrolysis and its conversion into three alternative fuels, such as methane, methanol, and ammonia, are considered. The four different Power-to-Fuel solutions are investigated and compared from both the technical and economic points of view aiming at providing a comprehensive overview of the...

In this paper, a thermo-economic analysis concerning a methanol production plant is performed. In particular, this study was developed with the aim of evaluating the opportunity and viability of obtaining methanol from the chemical reaction between recycled CO2, emitted from a fossil-fuel power station, and hydrogen produced by water...

This paper aims to investigate the innovative design of a ducted horizontal-axis wind turbine and to compare its energy production with a traditional free turbine for energy harvesting, both at laboratory and on relevant environment scales. The ducted wind turbine was designed considering a convergent-divergent duct, with the turbine in the...

In this paper, two different power-to-fuel solutions for sustainable fuel synthesis are investigated from the energetic, environmental, and economic standpoints. Both the solutions consider a pressurized PEM electrolysis section, fed by renewable sources, where high purity green Hydrogen is produced. Then, two separate processes are...

This paper aims to present a feasibility study of an innovative plant for methanol synthesis from carbon dioxide and hydrogen, produced by water electrolyser fed by renewable electrical energy. The analysis aims to examine a methanol production plant, based on 1MW of installed electrolyser, from both the management and economic standpoints: the...

This paper aims to study the application of distributed generation technologies on a naval energy system, investigating the best operating strategy for energy management throughout an annual load profile. The thermo-economic analysis is performed considering electrical and thermal load demands referred to hotel and service loads of a cruise...

This manuscript presents a clean energy solution for marine applications, investigating both the choice of the most promising production and storage technologies and, in a second step, the best operational management in order to satisfy a ship's energy demand. The case study subject of the analysis is a ferry, with a capacity up to 200 people,...
