Future Fuels: Responsibly Driving The Fleet Forward

The boating industry is making significant strides in adopting more sustainable practices. At the forefront of such revolution is the way we power the fleet. As this is becoming an increasingly important greener agenda topic, Boatbookings is proud to lead the way with our greener crewed catamaran fleet, adopting innovative and eco-friendly alternatives to non-renewable fuel sources. From electric hybrids to biofuels, here we outline an update on the various ways to power the fleet and the potential future of fuels: 


Electric Hybrid 

Many of the Boatbookings’ greener fleets feature state-of-the-art hybrid propulsion systems. These innovative boats combine traditional engines with electric motors and high-capacity battery banks, offering the best of both worlds. With these boats, you can cruise silently under electric power and then switch to conventional engines for longer journeys. With solar panels and wind turbines working to recharge the batteries, these boats epitomise flexible, greener cruising. 

Methanol 

Methanol is emerging as a leading alternative fuel for the boating industry. While it requires more storage space, it offers significant environmental benefits. We are excited to see developments like Sanlorenzo’s Almax 50 Steel, the first yacht to feature a green methanol fuel cell system for zero-impact cruising. This technology allows extended time at anchor without fuel consumption, supporting the hotel loads with minimal environmental impact. Lurssen is another shipyard that has been experimenting with methanol-based fuel cell technology on its Project Cosmos, scheduled for delivery in 2025. 

Hydrogen 

Hydron fuel cell technology also presents various advantages. Like methanol, while there are challenges in storage and energy generation, pioneering projects like Feadship’s Project 821 are pushing the boundaries of what is becoming possible. These fuel cells produce electricity with water as the only byproduct, offering zero-emission cruising. 

Biodiesel 

We see some larger yachts transitioning to biodiesel for immediate impact, such as Hydrotreated Vegetable Oil (HVO). These fuels, derived from renewable sources, offer a cleaner burn with significantly reduced emissions. HVO is particularly promising as it can be used as a direct replacement for existing diesel engines with only minor modifications, making it a great option for reducing the carbon footprint of the current fleet. Feadship and Azimut-Benetti are committing to HVO in their current and future yachts. 

Nuclear

Nuclear propulsion is also emerging as a viable power source for yachting, offering commercial and operational benefits alongside emissions-free sailing, according to Lloyd’s Register. Their recent report, “Fuel for Thought: Nuclear for Yachts,” highlights nuclear reactors’ potential to revolutionize yachting by providing higher power outputs, longer range, and superior performance. While there are challenges such as public perception and regulatory hurdles exist, the environmental and technological benefits make nuclear-powered yachts a potential prospect for the industry.

Energy Efficiency 

Sustainability isn’t just about alternative fuels; it’s also about using energy wisely. Today, yachts are now designed with such efficiency in mind, from LED lighting and smart climate control systems to hull designs that minimise drag. Yacht crew are also now trained in energy-efficient operations, implementing best practices that reduce waste and maximise the use of our renewable energy sources.

Looking Ahead 

As technology advances, so does our commitment to greener yachting. At Boatbookings, we continuously explore emerging technologies and incorporate greener vessels into our fleet. Whether that is more efficient solar panel technology, advanced battery technology, or new biofuels, we are dedicated to providing greener options for responsible boating vacations.

METSTRADE 2023 Updates: The Waves of Decarbonization

Decarbonization is an issue of high priority within the boating sector. At Boatbookings, we are passionate about this dynamic topic, regularly staying ahead of the developments and innovations working to reduce the industry’s carbon footprint. 

At this year’s METSTRADE show in Amsterdam, the International Council of Marine Industry Associations (ICOMIA) presented their latest report, ‘Pathways to Propulsion Decarbonization for the Recreational Marine Industry.’ 

The Report 

This comprehensive report focuses on boats under 24 meters. It outlines a strategic portfolio of technologies to propel the recreational marine industry toward a greener future. 

The research investigated propulsion technologies across nine common recreational watercraft, evaluating the impact on lifetime greenhouse gas (GHG) emissions, financial costs, usability, performance, range, and infrastructure. 

The technologies examined included battery electric, hybrid electric, hydrogen, and internal combustion engines (ICE) with sustainable marine fuels and traditional diesel engines. 

Main Findings

  • It emphasized the need for diverse solutions in the quest to reduce carbon emissions. Noting that 80% of a car’s environmental impact is in its usage, a far higher proportion of a boat’s environmental impact comes from its manufacture – as high as 50%. Given the unique on-water environments and varied interests of boats, the study suggests a one-size-fits-all approach is not feasible. Instead, the sector must consider a range of technologies. 
  • Among findings, sustainable liquid marine fuels, such as renewable drop-in fuels, emerge as a highly promising energy source for decarbonizing boats by 2035, potentially reducing emissions by 90%. 
  • Hydrogen also stands out as a potential source for emissions reduction, provided the production process is optimized. 
  • Electric propulsion, while part of the strategy, is stated not to be universally suitable for all types of craft and use cases. 
  • Hybrid boats that use electric motors and ICEs powered by liquid fuels offer the potential to reduce emissions from boats in certain scenarios – boats used for longer periods and over greater distances. Hybrid technology provides the most potential for emissions reduction for charter.

Report Recommendations

The report recommendations included the following:

1. Adoption of a technology-neutral decarbonization approach for marine environments.

2. Acceleration of the development and distribution of sustainable marine fuels, supported by educational campaigns.

3. Collaboration between consumer safety, government entities, and recreational marine industry to establish marine electric technology and safety protocols.

4. Expansion of R&D tax credits and investments to improve electric battery density and hydrogen research applicable to maritime. 

5. Continued research to evaluate existing and emerging technologies and optimal application. 

No Easy Answer

While an interesting report, there are evidently various connected factors that will prove influential in the coming years. These include innovative products, new technologies, changes in consumer behavior, improvements in recyclability, the reuse of materials, emerging battery technologies, and the availability of these sustainable fuels.
