Hydrogen as a marine fuel

open access: yes, 2022
Climate change is one of the most significant problems confronting our world, caused mostly by GHG emissions that trap heat in the earth's atmosphere, resulting in global warming. Shipping has a huge impact on global environmental pollution, notably air pollution.

A distributed virtual sensor scheme for marine fuel engines

open access: yes, 2022
This paper proposes a virtual sensor scheme designed to compensate for sensor fault effects in marine fuel engines. The proposed scheme design follows a distributed approach, where the marine fuel engine is decomposed in several subsystems.

Numerical Analysis of Emissions from Marine Engines Using Alternative Fuels

open access: yesPolish Maritime Research, 2015
The current restrictions on emissions from marine engines, particularly sulphur oxides (SOx ), nitrogen oxides (NOx ) and carbon dioxide (CO2 ), are compelling the shipping industry to a change of tendency. In the recent years, many primary and secondary

Natural gas as a marine fuel

open access: yesEnergy Policy, 2015
AbstractThis paper provides new knowledge about the life-cycle emissions of natural gas compared to traditional petroleum-based fuels in the marine sector. While natural gas will reduce local air pollutants, such as sulfur oxides and particulate matter, the implications for greenhouse gases depend on how the natural gas is extracted, processed ...

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and
