LISBON, Dec 19 (Reuters) - Portugal's Galp Energia anticipates to begin producing biodiesel and biojet fuel from waste in an industrial-scale unit it is developing at its Sines refinery in 2026, the business, which is mostly an oil producer and refiner, said on Thursday.

Last year Galp got in into a 75%-25% joint venture with Mitsui to invest 400 million euros ($415 million) in the Hydrogenated Vegetable Oil (HVO) plant, which will have a production capability of 270,000 metric loads per year.

It will transform waste products, such as utilized cooking oils, into sustainable biodiesel and biojet fuel, also called sustainable air travel fuel (SAF), utilizing green hydrogen produced by an electrolyser powered by wind or solar energy.

Galp said in a statement it received on Wednesday the 3 reactors to process biofuels, which will allow the HVO unit to “produce SAF and biodiesel in 2026 ... putting Galp at the leading edge of establishing low-carbon solutions necessary for the energy transition”.

Galp is likewise investing 250 million euros in a 100 megawatt (MW) electrolyser system to produce green hydrogen to power the refinery in Sines. ($1 = 0.9637 euros) (Reporting by Sergio Goncalves
