The Indonesian government is conducting trials of B50 biodiesel for railway diesel engines in Yogyakarta. These tests are part of a broader effort to ensure technical readiness across the strategic transport sector before a nationwide rollout scheduled for early July 2026. Trials for B50 have been ongoing since December 2025, with the railway sector being the final area to undergo testing. The move aims to reduce reliance on fossil fuels by integrating higher blends of biofuels into the national transport infrastructure.
