Velocys has released AlphaCore 800, its highest-capacity microchannel Fischer-Tropsch (FT) reactor, designed to produce up to 800 barrels per day, or 30,000 tonnes per year (30 kt/a), of FT fluids from a single unit. The reactor doubles AlphaCore 400's capacity and expands the portfolio from approximately 50 to 800 barrels per day per reactor, or 2 to 30 kt/a. Velocys is positioning AlphaCore 800 for larger sustainable aviation fuel (SAF) and e-fuels projects, including plants targeting approximately 100,000 tonnes per year or more. A 1,600-barrel-per-day (60 kt/a) FT plant could use two AlphaCore 800 reactors instead of eight AlphaCore 200 units, cutting reactor count by 75% while maintaining the same FT liquids capacity. The company says the larger format can simplify the FT island, reduce associated equipment requirements and lower unit costs while retaining the platform's chemistry, design, performance and reliability. AlphaCore 800 joins AlphaCore 50, 200 and 400, all based on the same core technology for different project scales and syngas pathways. Velocys CEO Matthew Viergutz said the launch responds to customer demand for simpler configurations in larger projects. The company's roadmap reflects growing demand for scalable SAF and e-fuels production, with developers seeking lower plant complexity, greater repeatability and stronger commercial cases for larger FT projects.
