In a groundbreaking study published in the journal *Engineering Results*, researchers have shed light on the environmental and economic viability of the Singapore-Rotterdam green shipping corridor, a pioneering initiative aimed at reducing greenhouse gas (GHG) emissions in maritime transport. The research, led by Ioannis Chalaris from the Department of Naval Architecture, Ocean, and Marine Engineering at the University of Strathclyde, offers a strategic forecast of GHG intensity for alternative fuels used in this corridor, providing valuable insights for the energy and shipping sectors.
The study focuses on the GHG intensity of bio-methanol, e-methanol, and marine diesel oil (MDO) used by an 8000 TEU containership operating within the green corridor until 2050. By integrating life cycle assessment (LCA) with the Holt-Winters additive method and considering econometric parameters such as GDP, population, and TEU demand, the researchers have developed a comprehensive model to evaluate the environmental impact of these fuels.
One of the most significant findings is that e-methanol produced using solar power exhibits the lowest well-to-wake (WTW) emissions, with a remarkable value of -24.49 g CO2 Eq./MJ. This aligns with the Fuel EU targets set for 2045, highlighting the potential of e-methanol as a promising net-zero pathway for shipping. “The source of electricity during production is critical,” emphasizes Chalaris. “Our study underscores the need for substantial investments in renewable energy infrastructure in both Rotterdam and Singapore to fully realize the benefits of e-methanol.”
The research also delves into the economic implications of fuel choices. According to the study, the total amount of penalties for non-compliance with Fuel EU regulations for e-methanol is estimated at €80.673.138,5, with the highest amount needed for allowances under the EU Emissions Trading System (EU ETS) reaching €4.352.943,4 in 2045. These findings provide a clear economic incentive for shipping companies to adopt e-methanol as a cost-effective and environmentally friendly option.
The establishment of green shipping corridors, such as the Singapore-Rotterdam corridor, is a crucial step towards decarbonizing the maritime industry. By sharing the expenses and benefits of using low- and zero-carbon alternative fuels, participants in these corridors are incentivized to make the transition. The study by Chalaris and his team offers a robust framework for evaluating the environmental and economic impacts of different fuel options, guiding stakeholders in making informed decisions.
As the world moves towards a more sustainable future, research like this plays a pivotal role in shaping policies and technologies that will drive the energy and shipping sectors forward. The findings not only highlight the potential of e-methanol but also emphasize the importance of investing in renewable energy infrastructure. With the global push for net-zero emissions, the insights from this study are timely and highly relevant, offering a roadmap for achieving a greener and more efficient maritime industry.
