The propulsion system is an integral part of ships with shafted propellers being the most popular configuration, as it is effective over a broad range of applications, despite all the hindrances mentioned in my previous post. Nonetheless there are many alternatives introduced over the years, attempting to improve the efficiency and limit the negative aspects….

Is hydrogen truly the environmentally friendly option for fuel? (Part B)
From the previous post, I’ve started the investigation for using hydrogen as fuel, looking initially at its production methods. Next it is imperative to examine the actual process of this energy storage method. I will try to capture all facets from bunkering, storing on board the ship till it reaches consumption. As in this context…
Is Hydrogen truly the environmentally friendly option for fuel?
Using hydrogen as fuel is an old concept, mostly aligned with the development of fuel cells. In the laboratories it has been proven since the beginning of the 20th century, yet only when the space program adopted it in the 70s, it gained mainstream traction. Then again till now the space program was the only…
Propeller is the primary driver, but can also be a major hurdle
Basic physics law, in order for an object to move, it needs to overcome its resistance. In the case a ship it is divided in several components, as explained in the previous post. In that article, we’ve focused on the impact of the frictional component of the overall wetted surface and then on the wave…
