The efficiency of maritime operations doesn’t merely hinge on operational practices; the intrinsic design and construction of ships play a pivotal role. Innovations in ship design and propulsion are ushering in new possibilities for reducing carbon emissions.
Carbon Capture and Storage (CCS)
The maritime industry acknowledges the continued reliance on traditional fuels. To address this, Carbon Capture and Storage (CCS) technologies, which trap and store CO2 emissions, have seen rapid adoption. For instance, ship management company Eastern Pacific (EPS) introduced carbon capture and filtering technology in their 50,000 ton dwt chemical tanker, reducing CO2 emissions by up to 40%. Meanwhile, Florida-based firm Greener Process Systems developed a Ship Emission Treatment in Harbor (SETH™) system, an off-ship solution that captures exhaust gases from vessels in port. Comprehensive trials and pilots are essential to evaluate the potential of CCS technologies. The Global Centre for Maritime Decarbonisation (GCMD) is spearheading a pilot with Stena Bulk to explore the complete cycle of carbon capture.

Hull Design Innovations and Energy Saving Devices
The hull’s design can significantly influence a vessel’s efficiency. While balancing cargo capacity and seakeeping qualities, naval architects are integrating novel concepts to optimise water flow and reduce resistance. NYK Line’s ‘Super Eco Ship 2050’ concept, unveiled in 2018, embodies such innovations with a hull form that minimises water friction. Energy Saving Devices (ESDs) enhance fuel consumption, making vessels more efficient. Techniques such as hydrogels that create a ‘liquid-like’ surface, reducing hull friction, and Silverstream Technologies’ air lubrication system have demonstrated substantial energy savings. As shipping potentially transitions to fuels with lower energy density, the significance of ESDs will grow, offering both environmental and business benefits.

Alternative Power Sources
The need for sustainable alternative fuels is paramount. Recent data indicates a significant focus on alternative power for maritime decarbonisation. However, a fragmented global fleet based on regional fuel options might emerge. The EU’s recent ‘FuelEU Maritime’ law and the U.S. Department of Energy’s ‘National Blueprint for Transportation Decarbonization’ spotlight the prioritisation of sustainable fuels like ammonia, hydrogen, and methanol. Wind-assisted propulsion is emerging as a promising tool in the maritime decarbonisation toolkit. Companies like Airseas are harnessing wind power for propulsion, developing technologies like the Seawing kite sail, aiming to reduce emissions by an average of 20%.

Connectivity and Data Exchange Infrastructure
Digital technologies and connectivity are revolutionising maritime operations, catalysing innovations that reduce emissions. Companies like ZeroNorth are leveraging vast data sets to derive insights that can substantially cut emissions and optimise operations. With platforms like these, the maritime industry can make significant strides in its decarbonisation journey, showcasing the power of data-driven strategies.
