Topsoe A/S (formerly Haldor Topsøe) is a Danish chemical engineering company specializing in catalysis, process technology, and catalysts for the refining, petrochemical, and energy industries. The company licenses process solutions and supplies catalysts, proprietary equipment, and engineering services for hydrogen, ammonia, methanol, syngas, and emissions control, supporting customers in project design, optimization, and plant operations worldwide.
Topsoe also develops technologies that enable lower-carbon fuels and chemicals, including solutions for renewable diesel and sustainable aviation fuel, blue and green hydrogen and ammonia, and e-fuels. Its portfolio spans hydroprocessing (e.g., HydroFlex), syngas and carbon management technologies, and high-temperature solid oxide electrolyzers (SOEC) for power-to-x applications. Headquartered in Denmark with global R&D, manufacturing, and service operations, Topsoe focuses on improving energy efficiency and reducing the environmental footprint of chemical and fuel production.

Preferred electrolyzer supplier for over 1 GW of e‑SAF projects; initial 280 MW GenEco will produce ~110 t/day renewable H2 for jet fuel at Port of Vordingborg; ENDOR moving to FID.
First industrial-scale use of 100% renewable diesel in Spanish mining; local Huelva production could cut ~2,600 tCO2/yr. New 2G complex planned with €1.2bn investment.
Moves FEED forward for a 50M gal/year RNG‑to‑SAF plant at Port of Walla Walla using Fischer‑Tropsch; permitting secured and start‑up targeted for 2031.
40,000 t/yr eSAF commitment for 10+ years from Project Endor in Denmark; deliveries planned from early 2030s; fuel claims up to 98% lifecycle emissions reduction and EU compliance.
Will leave the CEO role on 31 December 2026 and support handover through Q1 2027; Board has appointed Egon Zehnder to run the external CEO search.
FEED covers electrolyzers, ASUs, green ammonia loop, desalination, >100,000 t storage and port pipelines; FEED may convert to EPC subject to FID; projected capex ~$1.8bn.
Europe’s first purpose-built SAF plant will convert residual fats into ~100,000 t/yr drop-in jet fuel, targeting start-up in 2028 to support EU SAF mandates.
Regional platform mobilises 14 organisations to coordinate offshore wind, LNG/bioLNG, hydrogen, CCS, SMRs and infrastructure protection across the Baltic Sea region.
