Ending subsidies for fossil fuel heating systems from 2025, and phasing out gas boilers and other fossil fuel heaters by 2040. These are just two of the outcomes of a political agreement between the EU Council and the European Parliament, which was reached on December 7, 2023. Which measures were agreed …

The logistics sector is continually seeking innovations to improve service productivity and profitability in freight transport, such as reduced fuel consumption and automation in warehouses. However, the road transport sector in Europe currently faces challenges such as a shortage of drivers, unused …

Densely populated areas are major sources of air, soil and water pollution. Agriculture, manufacturing, consumer households and road traffic all have their share. This is particularly true for the country featured in this paper: the Netherlands. Continuous pollution of the air and soil manifests itself …

As fuel is expensive and profit must be maximized, it is wise for the maritime industry to invest in fuel saving applications. One of the possibilities is to replace old turbochargers by new fuel saving ones on the already installed engines, recommended by Wärtsilä. Although the potential fuel savings …

In this study, aviation, energy, exergy, environmental, exergoeconomic, and exergoenvironmental analyses are performed on a CFM56-3 series high by-pass turbofan engine fueled with Jet-A1 fuel. Specific fuel consumption and specific thrust of the engine are found to be 0.01098 kg/kN.s and 0.3178 kN/kg/s, …

The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …

In this research paper, it was concluded that there still remains a lot of uncertainty in the predicament of when a gas-trip can occur on dual-fuel propelled ships. In a situation on board of the Coral Energy, these gas-trips resulted in the main engine not being able to switch-over to gas-mode again. …

The carbon footprint for the downstream dairy value chain, milk collection and dairy processing plants was estimated through the contribution of emissions per unit of collected and processed milk, whereas that for the upstream dairy value chain, input supply and production was not considered. A survey …

The Nieuw Statendam is equipped with a program called ENIRAM. This program calculates the optimal engine configuration and load expressed in revolutions per minute of the propellers. The issue with this program is that it only looks at the main power plants and does not take the waste heat recovery system …

Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 …
