In the quest to meet the International Maritime Organization’s ambitious 2050 greenhouse gas emission targets, researchers are turning to alternative fuels like methanol. A recent study published in the journal ‘Wave’ (Gelombang in Indonesian), led by Abyan Ariaputra Aziz from UPN Veteran Jakarta, has shed light on the energy and operating costs of methanol fuel on a 4000 DWT oil chemical tanker, offering valuable insights for the maritime industry.
The study, which focused on round-trip shipping with route variations, composition, and fuel prices, found that methanol can significantly reduce emissions. “Methanol can reduce SOx emissions by up to 99%, NOx emissions by up to 60%, and Special Particulates by up to 95%,” Aziz noted. This is a substantial improvement over traditional heavy fuel oil (HFO), making methanol a compelling alternative for shipping companies looking to reduce their environmental footprint.
The research calculated the energy consumption and operating costs for three different routes: American, European, and Asia Pacific. The findings revealed that the energy consumption and operating costs varied depending on the route, with the American route having the highest energy consumption and operating costs, followed by the Asia Pacific and European routes. The study also calculated the payback period for the main engine retrofit, which ranged from 2.4 to 3.5 years, depending on the route.
From a commercial perspective, these findings present both challenges and opportunities. On one hand, the initial investment for retrofitting engines to use methanol is substantial, with the study estimating the cost at around Rp. 7,574,435,035. However, the long-term savings in operating costs and the potential to reduce emissions make a strong case for investment. As Aziz put it, “These findings offer valuable insights for shipping companies to make informed decisions about fuel selection and retrofit investments, potentially leading to significant cost savings and a reduced environmental footprint.”
Moreover, the study provides a strategic foundation for complying with IMO regulations and achieving long-term sustainability goals. As the maritime industry grapples with the need to reduce emissions, alternative fuels like methanol are likely to play a crucial role. The research published in ‘Wave’ serves as a valuable resource for maritime professionals seeking to navigate this complex landscape and make informed decisions about their fuel strategies.
In conclusion, the study led by Aziz highlights the potential of methanol as a cost-effective, low-emission, and environmentally friendly fuel alternative for the maritime industry. While the initial investment may be high, the long-term benefits in terms of cost savings and reduced emissions make a compelling case for its adoption. As the industry continues to evolve, research like this will be instrumental in guiding shipping companies towards a more sustainable future.
