The study-s aim is to assess the economic and environmental benefits of onshore power supply (OPS) implementation in port areas and to evaluate its cost-effectiveness under different energy price and emission trading scenarios. Specifically, the research investigates how OPS adoption impacts total annual costs, emissions of NOX, SO2, PM, and CO2, and overall cost-effectiveness expressed in euros per pollution unit. A quantitative simulation approach was employed using the OPS Calculation Tool, an Excel-based model...

Increasing the share of renewable energy sources for the generation of electricity in the public electricity network can have an important impact on the performance of the electricity system. An important problem in the electric power system is ensuring the continuity of the supply. The aim of the paper is to present a way to complement energy demand management and smart grids with models that follow changing energy production. This can be achieved by a holistic management system for diagnosis and risk assessment ...

The maritime industry represents a significant contributor to global greenhouse gas emissions, primarily through the combustion of fossil fuels used by ship engines. As international regulations tighten and environmental awareness grows, reducing global greenhouse gas emissions from ships has become an important objective. This study explores the potential for emission reduction on passenger ships through the implementation of a hybrid propulsion system. The study methodology involves solving the following aspects...

During the process of adapting renewable energy and ensuring national energy security in the current geopolitical context, technological progress in the field of green energy has received increased attention. This has led to the development of updated policies on investment in onshore renewable energy (which uses wind and solar energy through wind turbines and photovoltaic parks) and offshore renewable energy (which uses tidal, wave, solar, and wind energy through floating photovoltaic parks and wind turbines that...

This paper presents a research which consists in measuring potential energy which be obtained on the surface of water in motion and showing the phenomenon of пїЅwavesпїЅ monitoring in the Black Sea basin. For this were measured, processed and analyzed the amplitude of the waves, the frequency and the waves direction, more than 12 Mm shore, isobath of 50 m, to the coastal zone. There are described techniques and measurement accuracy durring one year. Also, are presented monitoring and processing data with graphycal...

The most important problems with a negative impact for Romanian coast, the erosion phenomen, are given by the numerous conflicts between the development of various economic activities and it is necessary to implement a system for preventing the further deterioration of shoreline. Coastal protection systems can be represented by linear structures perpendicular to the shore, called groynes. The groynes trapping sand on the upstream side and in this way, protect the coast behind the sand filet. The protection depends...
