JAKARTA, INDONESIA / RankWire.AI / – The B50 biodiesel program in Indonesia is forecasted to save approximately 170 trillion rupiah, equivalent to US$10.8 billion, in foreign exchange during 2026, according to the Energy and Mineral Resources Ministry. This projection accounts for reduced expenditures on imported diesel resulting from the increase of the national biodiesel blend to 50%. The regulation encompasses diesel used across transport, industrial sectors, shipping, railways, and electricity generation. Palm oil supplies the renewable component, while traditional diesel makes up the remaining half. The initiative replaces part of Indonesia’s fossil fuel consumption with domestically produced biofuel.
Indonesia commenced nationwide B50 utilization on July 1 and officially announced the mandate on July 9 in Karawang, West Java. It succeeded B40, which mandated a 40% biodiesel share since 2025. B50 consists of equal parts fatty acid methyl ester, known as FAME, and petroleum diesel. The increased requirement channels more palm oil into the domestic fuel market. Distributors are permitted to use remaining stocks of B40 through September while completing the transition to B50. Prior to the rollout, authorities updated fuel standards and distribution strategies.
The foreign exchange savings attributed to B40 is valued at Rp133.3 trillion. The B50 estimate raises this figure to Rp170 trillion for 2026. Officials also project the mandate will reduce fossil diesel consumption by approximately 4 million kilolitres. Pertamina has been tasked with managing blending operations and supporting fuel distribution nationwide. The company also oversees storage and supply logistics for regions participating in the program. The implementation includes technical standards for production, transportation, and retail distribution.
B50 Policy Boosts Domestic Biodiesel Demand
Indonesia anticipates B50 will require between 16.7 million and 18 million kilolitres of biodiesel. This volume surpasses the 15.64 million kilolitres allocated under the B40 program for 2026. Additionally, the mandate is expected to utilize roughly 15.2 million to 16.3 million tonnes of crude palm oil. These supplies will serve sectors including road transport, industrial machinery, maritime vessels, trains, and power plants. The volume estimates are based on projected nationwide demand under the new blend specifications.
Official forecasts suggest that the palm oil industry could benefit by Rp23.49 trillion. Furthermore, around 2.1 million jobs are expected to be supported across farming, processing, logistics, and fuel distribution sectors. The government estimates that B50 could reduce carbon dioxide emissions by as much as 44.46 million tonnes, compared to 39.66 million tonnes under the B40 scenario. These figures are part of the Ministry’s comprehensive assessment of the higher biodiesel blend, covering the entire program rather than specific regions or sectors.
Pre-Deployment Testing of B50 Initiated
Prior to the nationwide rollout, the government conducted extensive testing of B50 in various vehicles and machinery, including cars, trucks, mining equipment, agricultural machinery, trains, ships, and power plants. Light vehicle trials covered 50,000 kilometres, while heavier vehicles underwent testing over 40,000 kilometres. Mining machinery was operated for approximately 1,000 hours without significant engine issues related to fuel quality. The ministry confirmed that the tested fuel met all government standards and manufacturers’ technical specifications. These tests were completed before the official distribution began in July.
Indonesia has incrementally increased its biodiesel requirement since the introduction of B2.5 in 2008, progressing to B10 in 2013, B20 in 2018, B30 in 2020, B35 in 2023, and B40 in 2025. The B50 level represents the latest step in this ongoing process. Each transition involved adjustments to fuel standards, production capacity, and logistics systems, culminating in the current policy of equal parts biodiesel and conventional diesel in the national fuel mix for 2026.
