MOL Group has completed a successful production test of hydrotreated vegetable oil (HVO) and sustainable aviation fuel (SAF) at its Slovnaft refinery in Bratislava, marking a significant step in the company’s energy-transition strategy.
During the trial, HVO was produced by co-processing vegetable-origin feedstock — specifically cashew nut shell oil — with crude oil, while SAF was derived from partially refined used cooking oil alongside conventional feedstocks. Independent laboratory testing confirmed that both fuels met required specifications.
The Slovnaft trial builds on earlier co-processing efforts at MOL’s Danube refinery and demonstrates the company’s ability to adapt conventional refinery infrastructure to produce low-carbon fuels. MOL Group said the results show it is prepared to scale up alternative fuel production, supporting EU decarbonisation targets and regional energy security.
The company plans further development to enable commercial-scale output of both HVO and SAF. MOL Group noted that the dual capability is particularly relevant given growing demand for renewable diesel and sustainable aviation fuels across Europe, alongside increasingly stringent emissions and sustainability regulations.
“This trial underscores our commitment to lowering emissions from diesel and jet fuels while making the most of existing refinery assets,” a company spokesperson said. MOL Group considers the dual HVO/SAF capability a central element of its long-term sustainable fuels roadmap.
The initiative highlights how traditional refining infrastructure can be leveraged to meet evolving energy and environmental requirements, supporting the transition to a more sustainable European transport sector.
