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.

Wind propulsion specialist Norsepower Oy Ltd has received its largest order to date for its cutting-edge Rotor Sail™ technology. The order was placed by French shipowner Louis Dreyfus Armateurs SAS (LDA) to equip three low-emissions newbuild roll-on/roll-off vessels with the technology. The vessels will be used to transport aircraft assembly components for European conglomerate Airbus from Europe to the United States. The Norsepower Rotor Sail™ technology is a modern adaptation of the Flettner rotor concept. It utilizes electric power to spin cylindrical rotors on the ship’s deck, which then interact with the wind to produce a thrust. This reduces the vessel’s fuel consumption, thereby lowering emissions and costs. The vessels, designed by Deltamarin, will feature a combination of six 35-meter tall Norsepower Rotor Sails and two dual-fuel engines that run on maritime diesel oil and e-methanol. Additionally, advanced routing software will optimise the ships’ transatlantic journey, maximizing wind propulsion and minimising drag caused by adverse ocean conditions. The construction of these vessels is set to take place at Wuchang Shipbuilding Industry Group (WSIG). Mathieu Muzeau, Transport and Logistic General Manager at Louis Dreyfus Armateurs, highlighted the importance of wind propulsion in achieving net-zero targets set by the International Maritime Organization. By 2030, the new fleet is expected to produce 50% fewer CO2 emissions on the Transatlantic route compared to 2023. The rotor sails will be furnished with the newly patented Norsepower Sentient Control™ (NPSCTM), a real-time force measurement, control and savings reporting system. This tool allows for individual control of each rotor, managing the intricate aerodynamic interactions between the sails and the hydrodynamic behaviour of the ship. “This fleet-wide deal is a game changer for the whole auxiliary wind propulsion industry,” said Tuomas Riski, CEO of Norsepower. “Firstly, it is the biggest deal ever made in the mechanical sails market – and, in a world first, it includes our brand new Norsepower Sentient Control™ tool.”

Propulsion assistance technology may seem like a throwback to the past, but in this case, regression is progression - modern application of wind powered propulsion such as rigid or rotor sails can clearly make an important contribution to achieving emissions reductions, and it will be exciting to see the real-world operational results and ROI. While this won't scale out to all tonnage, with alternate fuel development, electric propulsion technology, hull efficiency improvements and big-data and AI driven voyage and fuel optimization it really is an exciting time to be in maritime and vessel operations!

The adoption of fully electric propulsion systems in the marine industry is growing very rapidly due to increased awareness about environmental impacts, impending regulations, and technological advancement. In every single marine vessel, the propulsion system consists of an electric motor, which in turn is driven by the propeller powered by batteries or some other source-not an internal combustion engine. Key Drivers: 1. Environmental Regulations: Organizations like the IMO are releasing more strict emission standards, which hike electric propulsion in view of the urgent objective to reduce the ships' GHG emissions. 2. Technological Advancement: Advances in battery technology and in the efficiency of electric motors further contribute to increasing the feasibility and economical viability of electric propulsion. 3. Value for Money: While the initial layout for an electric propulsion system is high, it promises long-term savings in fuel costs and maintenance. 4. Fuel Price Volatility: Volatility in fossil fuel prices makes the electric propulsion option increasingly viable, especially for short-haul routes and ferries. 5. Government Incentives: Most governments are providing subsidies and other forms of incentives for green technologies in electric propulsion for marine applications. Market Segmentation: 1. By Vessel Type: Commercial Vessels: Ferries, cargo ships, tankers, etc. Leisure Boats: Yachts, personal watercraft, etc. Military Vessels: Patrol boats, submarines, etc. 2. By Propulsion Type: Full Electric Propulsion Hybrid Propulsion: It combines the action of electric motors with the conventional engines. 3. By Region: North America Europe Asia-Pacific Rest of the World Challenges: High Initial Costs: In developing and installing electric propulsion systems, the cost is higher in contrast to traditional systems. Limited Range and Power: Batteries currently offer limited range and power and might be a drawback for long haul and larger vessels. Infrastructure Requirements: Lack of charging infrastructure in the ports can diminish the full electric systems. Key Players: Leading vendors in the global marine electric propulsion include Siemens AG, ABB Ltd., General Electric, Wartsila Corporation, and Rolls-Royce Holdings plc. These companies are investing a fortune in research and development for developing better efficiency and capability for electric propulsion systems. Outlook: The demand for marine fully electric propulsion systems is estimated to grow well in the coming years because of continued technology advancements coupled with increased environmental awareness. The growth rate is likely to be faster in the segments of small vessels and ferries while going upwards gradually in larger commercial and cargo vessels with the improvement of technology and infrastructure.

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.

The goal is to build a hybrid vessel that operates electrically over shorter distances and in hybrid mode over longer routes, contributing to lower emissions https://lnkd.in/dPdFbpzM
