This paper evaluates the potential impacts of introducing low-carbon intensity hydrogen technologies in two oil refineries with different complexity levels, emphasizing the role of hydrogen production in reducing CO2 emissions. The novelty of this work lies in three key aspects: Comprehensive system …

Shipping activities are increasing with sea ice receding in the Arctic, leading to higher risks of accidents and oil spills. Because Arctic toxicity data are limited, oil spill risk assessments for the Arctic are challenging to conduct. In the present study, we tested if acute oil toxicity metrics obtained …

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 …

Limestone is a sedimentary rock that is composed mostly of calcium carbonate (CaCO3). Limestone is, among many applications, used as a raw material for the manufacture of quicklime. When limestone is heated, the stone calcinates and quicklime is formed. The primary use of quicklime is in the steel and …

This thesis is concerning effective use of fuel on board the ALP STRIKER. The recent transfer from heavy fuel oil, to the more expensive marine gas oil led to ongoing discussions about the effective use of fuel on board. The goal was to find the optimum propulsion configuration on board for any attainable …

This article proposes an analytical model for a conversion from Heavy Fuel Oil (HFO) to Liquide Natural Gas(LNG) dual-fuel engine in a fleet with three sizes of vessels in order to investigate the impact of the volatility of oil prices, and a declining Energy Return on Investment (EROI) on opting LNG …

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 …

Due to the depletion of fossil fuel resources and concern about increasing atmospheric CO2 levels, the production of microbial oil as source for energy and chemicals is considered as a sustainable alternative. A promising candidate strain for the production of microbial oil is the oleaginous yeast Schwanniomyces …

Daily life is greatly influenced by fossil fuels. New technological inventions and the reduction of the ice coverage due to climate change makes it possible for humans to be present and undertake activities, such as gathering oil in previously inaccessible areas like the North Pole (Sagerup, Nahrgang, …
