In a significant move towards energy diversification, a recent study has explored the potential of torrefied sugarcane biomass as an alternative fuel for coal-fired power plants in the Philippines. As the country grapples with a rising reliance on coal—58% of its energy mix in 2021, up from 26% in 2008—this research offers a promising pathway to reduce carbon emissions while enhancing energy self-sufficiency.
The study, led by Jose Gabriel H. Escorial, presents a techno-economic modeling of a biomass torrefaction plant specifically designed to utilize sugarcane residues. By analyzing the geographic distribution of biomass resources and the locations of existing coal power plants, the research identifies Negros Island as an ideal site for the facility, with a focus on supplying six power plant units in Central Philippines that collectively have a capacity of 627 MW.
Escorial notes, “With the Philippines possessing 4,450 MW of non-food biomass resources, leveraging local agricultural residues can significantly contribute to our energy needs while supporting sustainability.” The research employs Aspen Plus™, a sophisticated process simulation software, to model a scaled-up production facility that can produce torrefied biomass at an economically viable level. The findings suggest that a co-firing rate of 5-10% of torrefied sugarcane biomass is achievable, with a levelized fuel price that is 20% lower than average Newcastle coal prices during 2021-2022, assuming a 12% internal rate of return.
This innovative approach not only addresses the urgent need for cleaner energy sources but also mitigates the risks associated with fluctuating coal prices, which are heavily influenced by geopolitical factors. The Philippines currently relies on imports for 91% of its coal usage, making local biomass production an attractive alternative. By investing in torrefaction technology, the country could enhance its energy independence and move towards a more sustainable energy model.
The implications of this research extend beyond the immediate benefits of cleaner fuel. It opens up new commercial opportunities for local farmers and biomass producers, creating a market for agricultural residues that would otherwise go unused. This could lead to job creation and economic growth in rural areas, aligning with broader goals of sustainable development.
As the Philippines continues to navigate its energy landscape, the findings from this study published in ‘Chemical Engineering Transactions’ highlight the potential for innovative solutions to drive the transition towards a greener economy. The research underscores the importance of leveraging local resources to meet energy demands while reducing carbon footprints, paving the way for a more resilient and sustainable energy future.
