The market and the industry are integrating decarbonization into their business model in the years to come. The International Maritime Organization aims to reduce CO2 maritime industry emissions by at least 50% by 2050.

The pressure and demand on the maritime industry to decarbonize will increase exponentially over the next three decades. The maritime sector is an essential aspect of international trade and accounts for 80-90% of world trade. This translates into emissions of approximately 3% of greenhouse gases into the atmosphere.
Decarbonization of the maritime industry
Decarbonisation of the maritime industry could be achieved through the use of various alternative fuels, for example methanol, ammonia, hydrogen and methanol, or traditional renewable energy sources such as solar energy , wind or biofuels.
Deep decarbonization requires huge financial incentives and investments, but also policy change at international and regional levels. Two common measures can reduce emissions, namely the management of operating factors such as waste heat recovery systems and speeds. The other metric is technical and relates to vessel size, engine design and efficiency, vessel port size and location, and interface. However, both have notable and significant challenges such as social acceptability, resource availability, and cost.
The advancement and maturity of operational strategies, techniques and technology of internal combustion or fuel cells of new or existing ships will contribute to the reduction of fuel consumption, thus contributing to decarbonization.
Introducing Artemis technologies to support maritime decarbonization
Artemis Technologies enables the design and development of zero-emission ships.
The team has versatile knowledge and abilities due to their developments in the world of racing. This led to the newly created and innovative product, the Artemis eFoiler, a zero-emissions scalable vessel. The system is based on electric propulsion and incorporates technology from the yacht racing, motorsport and aerospace industries.
The International Transport Forum has recognized that new measures can contribute to decarbonisation. However, electric ships would be more than a palliative to this problem, which the company Artemis Technologies is trying to achieve.
Artemis eFoiler Specifications
The vessel has a maximum propulsion speed of over 30 knots, with a cruising speed of around 25 knots. The range at cruising speed is 60 nautical miles or 110 kilometers, making it suitable and scalable for various applications.
The Artemis eFoiler is designed to fly over the waves for a quieter, faster ride. It also minimizes the wake generated by the vessel which could potentially cause damage to fish, wildlife habitats, shorelines and other vessels.
The hydrofoil “T” section integrated into the transmission design eliminates the need for a driveshaft in the structure. The specific modification of the mechanical system allows for greater efficiency and the vessel can operate at higher speeds. The component has a high aspect ratio and the shape is optimized for performance based on different ship characteristics.
To manage the vessel’s ability to fly over the waves, the technology incorporates an autonomous multi-layer control system, meaning it works like an autopilot. The height of the ship is also managed by the flight control system.
The vessel is powered by a power electronic control unit reinforced with silicon carbide modules, transforming electrical energy with high efficiency. Silicon carbide modules are currently used in the electric vehicle industry and can operate at higher temperatures and voltages, and have low switching losses. They also reduce costs and improve the overall system.
The Artemis eFoiler versus traditional diesel ships
The Artemis eFoiler vessel is powered by an electric propulsion system and differs greatly from the design of traditional diesel vehicles. The eFoiler is expected to be more efficient than traditional diesel vessels.
The eFoiler can operate at higher speeds than other vessels for two specific reasons. The first is that the wake created is limited and does not cause damage. Other ships are forced to limit speeds through regulations. The second is that less power is needed to maintain and reach top speeds, which adds to the efficiency of the design.
Finally, like other e-transport developments, fuel costs are significantly lower at around 90% less than traditional vessels.
Optimize the design process with simulations
In developing the Artemis eFoiler, the company generated a simulation tool called eSim to facilitate ship upgrades. This allows the vessel to be scalable in type and size while optimizing the design. Specifically, the technology encompasses modeling tools such as fluid-structure interaction, section shape, and detail optimization while ensuring project efficiency.
The eSim improves the ability to select hydrofoil modules, manage the hybrid structure, correct the flight control system and optimize other design components.
The simulator can be adapted to different applications, from work boats and ferries to pleasure boats before any construction. Another benefit of the technology is that it can train crew and skippers on how to navigate the vessel through realistic and immersive experiences.
What’s next for Artemis Technologies?
As the company strives to bring its technology to market, several scalability opportunities have presented themselves.
Artemis Technologies leads the Belfast Maritime Consortium ferry project. The project aims to decarbonize maritime transport through autonomously operated electric hydrofoils that will be established as a water taxi service. The planned completion of the project is March 2024 and hopes to bring education, policy change and employment opportunities to the area.
The company was an exhibitor at the COP26 summit in Glasgow, UK in 2021. This is a great opportunity for the company, as a market leader in decarbonization vessels, to present its designs to executives and companies of the world.
