Australian developer Allied Biofuels has signed a binding "project implementation agreement" with the Khorezm regional government in Uzbekistan to develop a $6.08bn complex with a combined 417,400 t/yr sustainable aviation fuel (SAF) production capacity.
The agreement is backed by a presidential decree granting the project special economic zone status as well as tax and customs exemptions.
The total estimated capital cost has risen from a previously stated $5.5bn. Allied Biofuels will invest the $6.08bn over five years. The firm said in October 2025 that it expects a final investment decision in the fourth quarter of 2026.
The plant will produce 160,400 t/yr of bio-SAF, 257,000 t/yr of synthetic e-SAF and 5,040 t/yr of renewable diesel, powered by 4.45GW of renewable generation capacity with 1.6 GWh of battery storage.
Allied Biofuels plans a hybrid biogenic and synthetic production complex using sorghum as the primary feedstock. The sorghum will be converted to first-generation bioethanol, which will then be processed into SAF via the ethanol-to-jet pathway. Total agricultural feedstock consumption is estimated at around 5,775 t/d. The firm signed a preliminary agreement with Indian engineering firm Praj Industries in November 2025 to supply its ethanol production technology, targeting 293,700 t/yr of ethanol output.
The complex will also capture biogenic CO2 from the same ethanol plant and gasify biomass residues into syngas, combining these with renewable hydrogen from electrolysers to produce e-SAF, likely via the Fischer-Tropsch route. Allied Biofuels signed a binding deal with US firm Plug Power to supply 2GW of electrolysers, which was raised to 2.4GW.
Sister firm Allied Green Ammonia is developing a renewable ammonia project in Australia, also using Plug electrolysers.
