Recently, Indonesia’s Minister of Energy and Mineral Resources announced plans to enforce a 10% bioethanol blend in gasoline by 2027, a key component of its strategy to reduce reliance on fuel imports. This policy aligns with the country’s broader goal of achieving energy self-sufficiency through expanded use of biofuels derived from palm oil, sugarcane, and other agricultural feedstocks.
Policy Details and Rationale
The mandate, part of Indonesia’s updated 2025–2035 biofuel roadmap, aims to replace fossil fuels with renewable alternatives while boosting domestic agricultural industries. The government estimates that implementing a 10% blend (E10) will require 1.4 million kiloliters of bioethanol annually . This initiative mirrors Indonesia’s successful biodiesel program, which has scaled from B10 to B40 (10–40% biodiesel blends) over the past decade, reducing foreign exchange costs and carbon emissions .
However, the rollout faces challenges. Current bioethanol production falls far short of demand. In 2024, Indonesia’s annual bioethanol capacity stood at 303,325 kiloliters, but actual output was only 160,946 kiloliters—a 53% capacity utilization rate—with 11,829 kiloliters imported . Domestic demand that year was 125,937 kiloliters, while 46,839 kiloliters were exported .
Feedstock Diversification and Infrastructure Development
To bridge the supply gap, the government plans to cultivate 1 million hectares of cassava and 400,000 hectares of sugarcane specifically for bioethanol production . Cassava, a drought-resistant crop, could theoretically yield 3 million kiloliters of ethanol annually from 1 million hectares, surpassing the E10 requirement . Sugarcane-based ethanol production is also expanding, with a 900,000-kiloliter-per-year complex under construction in Merauke, South Papua, scheduled for completion in 2027 .
Additionally, sugar palm is being promoted as a sustainable feedstock. The government aims to plant 1.2 million hectares of sugar palm by 2030, with 300,000 hectares targeted for 2025 . Each hectare of sugar palm can produce 24,000 liters of ethanol, offering a viable alternative to food crops .
Challenges and Controversies
- Feedstock Competition: Sugarcane and cassava compete with food production and palm oil for land. For example, the Merauke Integrated Food and Energy Estate in South Papua has faced criticism for displacing indigenous communities and threatening rainforests .
- Technical Bottlenecks: Only 4 out of 13 ethanol producers in Indonesia can produce fuel-grade ethanol, and second-generation (cellulosic) ethanol technologies remain in pilot stages .
- Financial Sustainability: While the government offers 20-year tax holidays and subsidies of $0.10–0.15 per liter for bioethanol projects , funding gaps persist. The biodiesel program’s $970 million subsidy in 2023 highlights the fiscal burden of such initiatives .
Global Context and Future Outlook
Indonesia’s E10 mandate is part of a broader trend in emerging economies. Brazil, for instance, will implement E30 (30% ethanol blend) by 2025, while India aims for E20 by 2025–26 . The International Energy Agency (IEA) projects global biofuel demand to rise 30% by 2028, driven by policies in countries like Indonesia .
However, success hinges on resolving supply chain issues and ensuring social and environmental sustainability. As one industry source noted, “It may be difficult to meet the target without a very strong strategy” . The government’s ability to attract private investment, upgrade infrastructure, and balance agricultural priorities will be critical to the policy’s success.
