Vattenfall, in collaboration with partners like St1 and Preem, is at the forefront of decarbonizing industries through fossil-free hydrogen and electrofuels. By leveraging fossil-free electricity and hydrogen, Vattenfall aims to decarbonise sectors like refining and petrochemicals. One of the key projects involves investigating the production of electrofuel for the aviation industry, known as eSAF, which is a sustainable aviation fuel. Feasibility studies have highlighted the growing potential of electrofuels, with expectations for the eSAF market to reach maturity in the 2030s. Vattenfall has outlined crucial success factors for the future, emphasizing the need to manage production costs, establish a robust regulatory framework, and enhance energy efficiency. While the HySkies partnership with Shell and related projects were paused due to market maturity concerns, the focus remains on advancing large-scale production of eSAF. This strategic shift aligns with the vision of transforming the aviation sector towards sustainability and reducing carbon emissions. Moreover, initiatives like the development of a hydrogen gas plant by Preem signify significant progress towards achieving fossil freedom in the energy landscape.
