Sailing Towards a Greener Horizon: The Impetus of Renewable Energy on Maritime Trade

In recent times, the need for a green transition has become more apparent, particularly within the maritime industry, which forms the backbone of global trade. As a significant contributor to greenhouse gas emissions, the shipping industry has been seeking ways to decarbonize and embrace renewable energy solutions. Here's a deep dive into the ripple effects of such a transition on maritime trade and global climate change mitigation efforts.

The maritime sector is a critical player in the global economy, with approximately 90% of worldwide trade being conducted through ocean-going vessels1. However, the reliance on heavy fuel oil, which covers about 82% of the sector's energy needs, has positioned shipping as a notable emitter of greenhouse gases, accounting for three per cent of global CO2 emissions23. The predominant use of fossil fuels not only exacerbates the climate crisis but also constitutes a significant portion of shipping activities across the globe.

A transition towards renewable energy in the shipping sector could potentially halve the number of ships traversing the oceans, as many of these vessels are primarily engaged in transporting coal, oil, and gas. This reduction in fossil fuel transportation aligns with the broader global shift towards clean energy, and embodies a dual benefit - curbing greenhouse gas emissions while reducing maritime traffic.

The transition strategy hinges on a combination of energy efficiency measures and the adoption of renewable fuels. In the near term, advanced biofuels are envisaged to play a pivotal role in reducing CO2 emissions, while green hydrogen-based fuels are projected to be the linchpin for decarbonisation in the medium to long-term4. This shift to renewable fuels is not without its hurdles. The higher cost of renewable fuels compared to conventional fossil fuels is a notable challenge. However, despite the cost differential, there's a growing interest and active pilots aiming to test the feasibility and benefits of such a transition. For instance, a successful trial was conducted by a Japanese shipping company using biofuel to power a vessel, marking a significant step towards cleaner marine fuels5.

The ripple effects of renewable energy adoption in the shipping sector extend beyond emissions reduction. The potential decrease in the number of ships transporting fossil fuels across the oceans could lead to less congested shipping lanes, which in turn may result in fewer maritime accidents and lower operational costs. Additionally, the reduction in the demand for fossil fuels could further accelerate the global transition towards a greener, more sustainable energy paradigm.

Investing in renewable energy technologies and fostering strategic partnerships among stakeholders are crucial to expedite this transition. The switch to renewable fuels is an investment not just in the maritime sector, but in a greener and more sustainable global economy. As the world continues to battle the climate crisis, steering the maritime industry towards renewable energy adoption is a voyage worth embarking on.
