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

Last year Galp participated in a 75%-25% joint venture with Japan's Mitsui to invest 400 million euros ($415 million) in the Hydrogenated Vegetable Oil (HVO) plant, which will have a production capacity of 270,000 metric loads each year.

It will change waste products, such as utilized cooking oils, into eco-friendly biodiesel and biojet fuel, also referred to as sustainable aviation fuel (SAF), using green hydrogen produced by an electrolyser powered by wind or solar power.

Galp stated in a declaration it got on Wednesday the three reactors to process biofuels, which will allow the HVO unit to "produce SAF and biodiesel in 2026 ... positioning Galp at the leading edge of establishing low-carbon solutions necessary for the energy shift".

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