Can SAF really help the sector transition to net zero?

Sustainable aviation fuel (SAF) is increasingly seen as a vital tool in the aviation sector’s transition to net zero. These drop-in fuels, which can be derived from bio and renewable-derived syngas, are used to dilute the fossil-derived components of fuel and are fully compatible with existing fuel infrastructure. This positions SAF as a convenient and rapid route towards decarbonisation. However, questions remain around its ultimate viability at scale and whether it really can be the ‘silver bullet’ aviation leaders are looking for. We spoke to Paul Ticehurst from Johnson Matthey (JM) to shed some light on SAF and the future role of syngas in aviation.

Sulphuric Acid News Roundup

Metso is launching an advanced sustainable battery black mass recycling process as part of its battery minerals technology offering, which covers concentration and hydrometallurgical processing as well as related services. Demand for battery minerals is increasing sharply with the ongoing transition to clean energy sources. An electric car battery weighs approximately 200 kg. Recycling of black mass from batteries with Metso’s process can reduce up to 60% of embedded carbon compared to use of virgin materials and enables the treatment of mechanically separated and shredded batteries for recovering battery raw materials like nickel, cobalt, and lithium, as well as manganese and copper.

Freezing the furnace

Debopam Chaudhuri of Fluor Daniel India Pvt Ltd and Michiel Baerends of Fluor B.V. Netherlands investigate how SO2 impacts the Claus furnace temperature in an SRU and the ways to mitigate it. This article studies the extent of quenching experienced in the Claus furnace with varying amounts of SO2 in the Claus feed. A case study is presented based on real operating data of a refinery Claus plant with a feed gas cocktail that includes substantial SO2 recovered from a regenerative flue gas desulphurisation unit.

Emissions-free syngas manufacturing

The world’s most common syngas production method remains steam methane reforming, a process which has a substantial CO2 footprint as the necessary reaction heat is supplied by combustion of hydrocarbons. Topsoe’s eREACT™ technology allows for the first-of-its-kind electrification of the traditional SMR process. The reaction heat for eREACT™ is instead generated directly by (renewable) electricity, thereby eliminating the flue gas altogether. Having gone through scale-up from bench scale to industrially relevant pilot scale the technology is now ready for industrial application.
