Wind-assisted propulsion refers to the use of wind power to assist in propelling a vessel, typically a ship. This can include traditional sails, as well as more modern technologies like kite sails, Flettner rotors, or wingsails. The goal is to reduce fuel consumption and emissions by harnessing the power of the wind alongside traditional propulsion methods.

As we look at changing fuel sources, our whole design equation changes. When we value efficiency because it reduces volume and weight of battery, we invent new ways of propulsion. The greatest constraint on a system drives innovation. This is why we see decaying gains as a “learning rate” with new technology. We go for the lowest hanging fruit, and eventually that fruit requires a new tool to reach, and more innovation is needed. This is why we must not get stuck in our linear 1:1 swap out thinking. Especially for heavy industry. Swapping fossil fuels with another synthetic fuel may seem the easiest, but that is when we are locked in a fuel mindset. When we instead focus on efficiency, and ultimately “$ / service” or “$ / product”, we start to utilize non typical innovation by increasing revenue streams with hybrid optimizations. For example removing parts that are no longer needed. This simplifies all parts of the system. For example, we don’t need oil platforms, oil pipelines, oil refineries, oil distribution trucks, when we just install a single heat pump, with a thermal buffer tank powered by solar. All of that “baggage” disappears. So don’t get caught by the “greedy algorithm” that only navigates the next lowest hanging fruit. Chart a path for continued improvement, utelizing the most efficient overall systems, and the rest of the dominos will fall into place. Because we won’t need to work nearly as hard to support a system that is irrelevant when we remove it. The first one would be corn based biofuels. Once we electrify transportation, we stop needing gasoline, which is 10% inefficient biofuels. This removal allows us so much more capacity through replacement vs continuing to sustain an inefficient use of energy. Pay farmers for their solar electricity, and they will make more money being more productive per acre, empowering them and our economy when feeding our gas tanks the most efficient fuel, electricity. Just by switching you are are making an impact many times greater than your deferred oil purchases. And you will see the ripple effects in your bank account via lower taxes, lower health insurance, and lower direct payments for energy. At this point not switching isn’t just hurting yourself, it’s preventing others from saving money too.

Considering the boat's operation profile is essential in the modeling of a marine hybrid system. The operation profile outlines key factors such as the boat's speed, load variations, power requirements, and duty cycles, which significantly impact the design and performance of the hybrid system. Incorporating these details into the model allows for optimizing fuel efficiency, reducing emissions, and enhancing system reliability. A well-modeled hybrid system, aligned with the vessel's unique operating conditions, enables a more effective balance between internal combustion engines and electrical components, such as batteries or fuel cells. This results in improved energy management, extended operational range, and lower environmental impact. Furthermore, taking into account the operation profile during the design phase ensures that the hybrid system can handle real-world conditions, such as varying sea states, long voyages, and power demands, leading to more robust and sustainable marine operations. #Betriebsprofil #Boost_Hybrid #HTW_Berlin 🌍
