The maritime sector is in the midst of a paradigm shift in terms of its fuel management strategy.
The industry is focusing on creating sustainable shipping solutions that are not only cost-effective but also environmentally friendly.
In this context, the modelling of the maritime sector’s future fuel mix has become essential in determining the best possible approaches for the transition towards a low-emission future.
Environmental, Social and Governance (ESG)
One of the most significant influencing factors in maritime fuel management strategy is the Environmental, Social and Governance (ESG) regulations implemented by the International Maritime Organization (IMO).
These regulations aim to reduce the producing of harmful emissions, primarily by limiting the Sulphur content of shipping fuels to less than 0.5%.
LNG
This regulation has had a massive impact on the industry, forcing stakeholders to focus on alternative low-emission fuels, one of the primary solutions being the use of LNG.
The use of LNG as a fuel in the maritime industry has been encouraged by the IMO as an alternative to high sulphur fuel oil and diesel.
LNG has the advantage of providing substantial reductions in SOx and NOx emissions, as well as a reduction in CO2 emissions.
However, the fuel is not without its drawbacks, as the infrastructure and storage capacity required for its use are still limited and expensive.
Biofuels
Apart from LNG, biofuels have been proposed as a replacement for fossil fuels.
However, the production of biofuels comes with significant issues such as deforestation and land-use changes, which can cause serious environmental problems and jeopardize the industry’s sustainability efforts.
Hydrogen
Another alternative fuel that has been experimented with is hydrogen, which has the potential of being CO2-free.
However, the production of hydrogen by splitting water using electricity – electrolysis – is still expensive and inefficient.
The Transition is Essential
Despite the challenges, the transition from fossil fuels to alternative fuels is an essential aspect of ESG and excellent for the industry in the long-term.
Therefore, the modelling of a maritime sector’s future fuel mix is necessary, as it helps stakeholders determine the best fuels to adopt while considering factors such as energy efficiency, environmental impact, and economic feasibility.
Life Cycle Assessment (LCA)
One way this can be achieved is through the use of a modified Life Cycle Assessment (LCA) model.
An LCA model considers all aspects of the fuel life cycle, from extraction and transportation to production and end-of-life treatments.
A modified LCA helps stakeholders identify the environmental and economic costs associated with different fuel options.
Such information helps to make a more informed transition decision towards a low-emission future.
Multi-Criteria Decision Analysis (MCDA)
Another modelling approach that can be used is a multi-criteria decision analysis (MCDA).
MCDA frameworks help in decision-making by ranking the options being considered based on predetermined criteria.
This framework helps decision-makers weigh the benefits and drawbacks of different fuels with respect to specific criteria, such as cost-effectiveness, energy efficiency, and minimal environmental impact.
Collaboration is a Must
Another important aspect of enhanced modelling of maritime’s future fuel mix is collaboration.
Stakeholders can come together in an open forum to share knowledge and build industry consensus on the most effective way to transition to a low-emission future effectively.
Collaborations between stakeholders in shipping, fuel supply chain management, environmental science, and economics, are integral to creating the most comprehensive and inclusive modelling approach.
Operations and Efficiency
Furthermore, it is essential to assess the impact of fuel mix scenarios on shipping networks’ operations and efficiency.
Factors such as the availability of refuelling infrastructure, the impact on vessel speed and cargo capacity, and the overall costs of the associated supply chain must be considered.
In Conclusion
Enhanced modelling is a vital part of the maritime industry’s transition towards a low-emission future.
By considering factors such as environmental impact, energy efficiency, and economic feasibility, the industry can determine the most suitable fuel options for the future.
Collaborations between stakeholders and multi-disciplinary approaches are critical in creating an inclusive and effective modelling framework.
This step towards a sustainable future can have significant global impacts as it may open new markets and opportunities whilst preserving the environment, combating climate change and mitigating harmful emissions.
