In this study the environmental impacts of various alternative ship fuels for a coastal ferry were assessed by the life cycle assessment (LCA) analysis. The comparative study was performed with marine gas oil (MGO) natural gas and hydrogen with various energy sources for a 12000 gross tonne (GT) coastal ferry operating in the Republic of Korea (ROK). Considering the energy imports of ROK i.e. MGO from Saudi Arabia and natural gas from Qatar the Read More

This study deals with the use of hydrogen for the de-carbonization of the Resources and Energy Intensive Industries (REIIs) and gives a specific insight of the situation of the steel-making industry. The growing use of hydrogen in our economy is synonym for an equal increase in electricity consumption. This results from the fact that the current most promising technologies of H2 production is water electrolysis. For this purpose the EU hydrogen strategy fores Read More

The necessity of neutralizing the increase of the temperature of the atmosphere by the reduction of greenhouse gas emissions in particular carbon dioxide (CO2) as well as replacing fossil fuels leads to a necessary energy transition that is already happening. This energy transition requires the deployment of renewable energies that will replace gradually the fossil fuels. As the renewable energy share increases energy storage will become key to avoid c Read More

Renewable energy DC hydrogen production has become a new development trend. Due to the interaction between the weak damping of DC network and the negative impedance characteristics of power supply of hydrogen production the actual available power of renewable and hydrogen energy DC interconnection system will be lower than its rated setting value. To solve this problem this paper proposes an intelligent damping control to realiz Read More

The development of more sustainable and zero-emissions collective transport solutions could play a very important measure in the near future within smart city policies. This paper tries to give a contribution to this aim proposing a novel approach to fuel cell vehicle design and operation. Traditional difficulties experienced in fuel cell transient operation are in fact normally solved in conventional vehicle prototypes through the hybridization of the propulsi Read More

Hydrogen fuel cells are electrochemical power generators of high conversion efficiency and incredibly clean operation. Throughout the world the growth of fuel cell research and application has been very rapid in the last ten years where successful pilot projects on many areas have been implemented. In Malaysia approximately RM40 million has been granted to academic research institutions for fuel cell study and development. Recently Malaysia s Read More

Europe’s aviation sector continues its resilient and pioneering spirit as it leads the world’s transport system into its new era of great transformation. Surviving the pandemic it is adapting rapidly to satisfy the rising demand for competitive air mobility services while managing a scarcity of resources and embracing the new challenges of climate change and energy transition. Facilitated by ACARE the European Commission its Member States aviation research Read More

Commonly used materials constituting the core components of polymer electrolyte membrane fuel cells (PEMFCs) including the balance‐of‐plant were classified according to the EU criticality methodology with an additional assessment of hazardousness and price. A life‐cycle assessment (LCA) of the materials potentially present in PEMFC systems was performed for 1  g of each material. To demonstrate the importance of appropriate actions at Read More

The European Commission recently proposed requirements for the production of renewable fuels as these are required to decarbonize the hard-to-electrify parts of the industrial and heavy transport sectors. Power-to-X (P2X) energy hubs enable efficient synergies between energy infrastructures production facilities and storage options. In this study we explore the optimal operation of an energy hub by leveraging the flexibility of P2X including hydroge Read More

This study presents a novel design and development of a 280000 m3 liquefied hydrogen tanker ship by implementing a set of 6 Flettner rotors as an assistance propulsion system in conjunction with a combined-cycle gas turbine fuelled by hydrogen as a prime mover. The study includes assessment of the technical and environmental aspects of the developed design. Furthermore an established method was applied to simulate the LH2 tanker in differ Read More
