Green Shipbuilders Paving the Way for a Sustainable Maritime Future

Green shipbuilders are leading the way in creating a more sustainable maritime industry. They're using innovative designs and materials to reduce fuel consumption and emissions.

One example is the use of wind-assisted propulsion systems, which can reduce fuel consumption by up to 20%. This technology is being implemented by companies like Norse Power, a Norwegian startup that's developed a system of rotating sails to harness wind energy.

Green shipbuilders are also focusing on energy efficiency, with designs that minimize drag and maximize cargo capacity. This includes using streamlined hulls and optimized propellers to reduce energy consumption.

These advancements are crucial for reducing the maritime industry's carbon footprint, which accounts for around 3% of global greenhouse gas emissions.

Decarbonizing shipping is a complex task, and several challenges stand in the way. One major obstacle is the lack of viable alternative fuels, with no clear frontrunner in the race to replace traditional fossil fuels.

The shipping industry is hesitant to invest in new, advanced vessels due to the uncertainty surrounding how they will be fueled. This is because building a new ship is a massive endeavor that requires immense capital investment and takes around two to three years to complete.

Asset and infrastructure development are slow due to inadequate demand, making it difficult for shipbuilders and infrastructure developers to advance new technologies and build infrastructure that can accommodate future-ready vessels.

Uncertainties in regulations are another challenge, with carbon emission regulations advancing in regions like the European Union but lacking clarity on accountability. This has led to disputes between shipowners and traders, highlighting the growing complexity behind regulatory enforcement.

The global nature of shipping means that a unified industry effort is needed to prevent emissions from shifting from regions with tight regulations to those with less stringent measures. However, with too many stakeholders involved in each shipment, it's unclear who should be accountable for the carbon emitted.

The adoption of alternative materials, such as eco-friendly composites and non-toxic coatings, can reduce the harmful impact on the environment. However, the transportation impact of green materials, like green steel, can negate their sustainability benefits if they have to be transported long distances.

Green technologies are gaining traction in the maritime industry, including cleaner propulsion systems, energy-efficient designs, and the use of alternative fuels like methanol. Methanol presents a compelling sustainable alternative due to its potential to repurpose carbon emissions and its practical storage and handling capabilities.

However, challenges like engine availability and uncertainties regarding the carbon source for methanol fuels remain. These complexities highlight the industry's transition towards greener solutions.

Subsidies in the shipbuilding sector present a multifaceted challenge, inducing market distortions and contributing to overcapacity, diminished profitability, and financial strain. However, subsidies remain indispensable for advancing decarbonisation efforts, including in ship construction.

Breaking the gridlock in shipping requires a fundamentally different strategy, one that creates real change in one field and sparks progress in others.

Green ship technology is a central piece of the puzzle in achieving decarbonization, with 85% of emissions coming from deep sea ships.

At Hanwha, we believe in delivering disruptive yet economically feasible technical solutions in this field, with our subsidiary Hanwha Ocean dedicated to making it happen.

To generate demand for green ship technology, we've joined the World Economic Forum's First Movers Coalition and established a global shipping company with a new fleet of cutting-edge vessels.

We're also stepping up the development of ship digitalization, aiming to power vessels with fuel cells and electricity.

To build scale and momentum, we're collaborating with multiple stakeholders, including policymakers, customers, and research institutes, through our membership with the FMC.

However, mass adoption and commercialization of new technology require a concerted effort between the public and private sectors, as well as parties across the entire energy value chain.

Clearly defined global regulations will be crucial in building an ecosystem for change and scaling green vessels.

Big problems require bold solutions, and the shipping industry is no exception, with a singular driving force having a ripple effect and opening up new opportunities for many different parties.
