Technip Energies, LanzaTech collaborate on CO2-to-ethylene technology

Technip Energies (THNPF) and LanzaTech Global (LNZA) signed a Joint Collaboration Agreement to create a new pathway to sustainable ethylene utilizing their combined technologies. Together LanzaTech’s carbon capture and utilization technology with Technip Energies’ Hummingbird technology transform waste carbon into ethylene, the most common building block in petrochemicals. Ethylene is a building block for thousands of chemicals and materials, including plastics, detergents, and coatings that keep hospitals sterile, people safe, and food fresh. Its traditional production process is also one of the largest sources of carbon dioxide emissions in the chemical industry and remains one of its most challenging processes to decarbonize. This new joint process uses carbon emissions as the starting point rather than virgin fossil carbon. First, up to 95% of the CO2 in the flue gas is captured from the furnaces of an ethylene cracker and mixed with hydrogen. Next LanzaTech’s biorecycling technology transforms the captured waste carbon into ethanol. Finally, Technip Energies’ Hummingbird technology dehydrates the ethanol to ethylene.
