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

If carried out, the B40 required might increase biodiesel consumption to as much as 16 million kilolitres (KL) next year, the ministry said, from 13 million KL approximated to be consumed in 2024.

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

The Indonesian Biofuel Producers Association (APROBI) said the market had the capability to satisfy B40 need, with installed capability anticipated to increase to 20 million KL yearly next year from 18 million KL now.

"However we will require more raw products to fulfill B40 need," Ernest Gunawan, the secretary general of APROBI informed Reuters on Wednesday.

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

Indonesia's greatest palm oil association GAPKI said a decrease in exports indicated there would suffice raw materials to provide the B40 mandate in the meantime.

But the industry would need to examine "which one would be more important", GAPKI chairman Eddy Martono stated, describing the possibility a boost in exports would make supplying the domestic market less viable.

Indonesia's palm oil output is approximated to reach 54.4 million loads in 2024, a 2.26% increase from last year, while exports are expected to decrease by 2.47% to 29.5 million loads as domestic usage rose, driven by biodiesel required.

The ministry had evaluated the biodiesel, mixed with 40% of palm oil, on a train for the very first time earlier today, while planning to check the B40 mix on farming equipment, power plants and in the shipping market, it stated. (Reporting by Bernadette Christina and Dewi Kurniawati
