Methanol-to-jet fuel nears approval for SAF supply boost

While Honeywell's technology and fuel samples were instrumental in the qualification process, the MTJ pathway, once officially adopted into ASTM's D7566 aviation fuel standard, will be accessible to all producers adhering to the approved specifications. Participants in the process indicated that the pathway has passed balloting within ASTM, with only minor comments remaining to be addressed. These final steps are expected to be resolved at ASTM meetings scheduled for next week in Chicago.

ASTM had not immediately confirmed the news, as the organization typically announces approvals through updates to its standard. Honeywell anticipates a public announcement in July, according to Rajesh Gattupalli, president of Honeywell UOP. The development of new aviation fuel pathways involves extensive testing and review, a process that has taken several years for MTJ.

This impending approval is seen as removing a primary technical hurdle for MTJ, enabling the sector to concentrate on economic viability and investment decisions. Previously, the absence of ASTM approval had deterred companies from making commercial commitments. Gattupalli emphasized the critical role of ASTM certification in securing financing, government incentives, and offtake agreements from airlines.

Honeywell has already licensed its technology to numerous developers who have been preparing offtake deals, financing, and incentives in anticipation of this approval. The company foresees the strongest traction for MTJ in Europe, driven by SAF mandates, as well as in China and India, where renewable energy potential is substantial. Some companies are planning to produce biomethanol from biomass-derived syngas, while others are exploring e-methanol production using renewable hydrogen and captured carbon dioxide, with some projects intending to use a combination of both.
