JAKARTA, July 24 (Reuters) - Indonesia, the world's greatest palm oil manufacturer, is evaluating fuel with a view to increasing to 40% from 35% the share of palm-oil combined into biodiesel next year, the energy ministry stated.

If executed, the B40 required might increase biodiesel intake to approximately 16 million kilolitres (KL) next year, the ministry said, from 13 million KL estimated to be consumed in 2024.

"We hope the trials could be finished in December, so that complete execution of B40 might be performed in 2025," energy ministry senior main Eniya Listiani Dewi stated in a declaration on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) stated the market had the capacity to satisfy B40 need, with installed capacity expected to rise to 20 million KL annually next year from 18 million KL now.

"However we will need more basic materials to satisfy B40 need," Ernest Gunawan, the secretary general of APROBI informed Reuters on Wednesday.

The biodiesel industry would require 13.9 million metric loads of crude palm oil to produce 16 million KL biodiesel next year, from the approximated 11 million loads needed this year, he included.

Indonesia's biggest palm oil association GAPKI stated a decrease in exports implied there would be sufficient basic materials to the B40 required in the meantime.

But the market would need to evaluate "which one would be better", GAPKI chairman Eddy Martono stated, describing the possibility an increase in exports would make supplying the domestic market less viable.

Indonesia's palm oil output is estimated to reach 54.4 million heaps in 2024, a 2.26% boost from last year, while exports are expected to decrease by 2.47% to 29.5 million heaps as domestic intake increased, driven by biodiesel required.

The ministry had checked the biodiesel, blended with 40% of palm oil, on a train for the very first time earlier this week, while preparing to test the B40 mix on farming equipment, power plants and in the shipping industry, it stated. (Reporting by Bernadette Christina and Dewi Kurniawati
