The present research study aims at analysing technical and economic feasible solutions for heat pumps integration in energy districts for polygeneration purpose and particularly to store excess of electricity via Power-to-heat schemes considering that, from previous researchers' works, thermal storage has been identified as the most...

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...

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...

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...

A simple novel small-scale time flexible containerized power to ammonia concept, employing conventional technology only, which is going to be realized in 2023 in Italy, is being investigated. The design focuses on investment cost minimization and time-flexibility, presenting a middle way between large-scale conventional ammonia plants and more...

This paper aims to present a thermo-economic approach for methanol production comparing different renewable energy sources. In this study, the methanol is produced from the CO2 hydrogenation in a pressurized reactor; two different plant configurations are analyzed: in the first carbon dioxide is obtained from biogas upgrade, while in the second...

This paper aims to present the upgrade of the Helper for Energy Layouts in Maritime applications (HELM) software tool, developed by the authors to compare traditional and innovative systems for energy production and storage onboard maritime vessels. The algorithm adopts a multi-criteria method and it carries out the analysis on a large and...

Power-to-X solutions are getting year by year more and more market interest in the present and future Renewable (RES) driven energy market scenario. Their potential coupling with Combined Cycles Gas Turbine (CCGT), which have to be present together with RES as back-bone to guarantee grid resilience and stability, is currently under...

This paper proposes a novel approach for the optimal scheduling and control of a microgrid with an electrolyzer and fuel cell systems, both of proton exchange membrane (PEM) technology. It is based on a hierarchical procedure constituted of two levels of optimization: a higher level based on an economic optimization for the optimal scheduling...

New policies and strict emission limits in the transports sector result in a gradual switch towards alternative fuels and hydrogen is getting attention: fuel cell systems are considered ideal energy converters of the next future. As the interest is rising in Proton Exchange Membrane Fuel Cells (PEMFC), there is a need for experimental research...

A major goal of politics, society, and industry is the reduction of carbon dioxide (CO2) emissions in order to prevent anthropogenic climate change and an increase in earth's temperature. In addition, the expansion of renewable energies and the use of nuclear power, CO2 capturing (e.g. from exhaust gases), is regarded as a promising strategy to...
