Could Methanol-to-Jet Technology Unlock the Future of Sustainable Aviation Fuel?

A new Methanol Institute report highlights a promising pathway for Sustainable Aviation Fuel (SAF).

The report identifies Methanol-to-Jet sustainable aviation fuel (MtJ) as a major accelerator. It suggests MtJ technology can combine strong MtJ emissions performance with significant scale. This could help overcome current supply and cost challenges for the next wave of Sustainable Aviation Fuel.

The Methanol-to-Jet Advantage

MtJ is a synthesis-based route for producing SAF. It uses methanol as a feedstock, which can come from diverse sources. These sources include captured carbon dioxide (CO2) and renewable hydrogen. This process is part of the broader Power-to-Liquid (PtL) production method.

Experts view the methanol pathway as advantageous. It offers high jet fuel yield and low byproduct formation. The technology is also highly scalable and modular. This modular nature allows for easier integration into existing infrastructure. Companies like ExxonMobil and Honeywell-UOP are developing proprietary MtJ processes. These processes aim for high SAF yield and lower operating costs. This focus on scale and cost advantages is critical for the decarbonizing air travel goal.

Pathway to ASTM Approval

For any new fuel, rigorous testing is mandatory for commercial use. The MtJ pathway is currently undergoing evaluation for approval by ASTM International. This evaluation follows the ASTM D4054 standard practice. Once approved, MtJ will join other certified routes for alternative jet fuel production. This will significantly expand the available feedstock pool for SAF.

Global Market and Regulatory Context

The aviation industry faces ambitious net-zero targets by 2050, set by bodies like IATA. However, SAF represented only about 0.3% of global jet fuel produced in 2024. The market is currently experiencing a supply shortage. Furthermore, SAF costs remain high, estimated at 1.2 to 7 times the price of conventional jet fuel.

Regulatory mandates are driving demand and investment.

• The European Union’s ReFuelEU Aviation regulation mandates a progressive increase in SAF use.
• This mandate starts at a 2% SAF blend in 2025.
• The required blend will rise to 70% by 2050.
• The US has set a goal to scale domestic SAF production to three billion gallons annually by 2030.

This regulatory push creates a strong demand signal. The aviation industry sustainability goals depend on new, scalable technologies like MtJ. The Methanol Institute’s findings suggest MtJ could be a major solution. It can help meet the rapidly growing global demand for SAF.

Outlook for Commercial Aviation

The successful commercialization of MtJ will impact airlines directly. It promises a more stable and cost-effective SAF supply chain. This stability is crucial for meeting regulatory compliance. It also supports airline commitments to lower their carbon footprint. The Methanol Institute’s research emphasizes the need for infrastructure investment. This investment will ensure the necessary renewable methanol feedstocks are available. The MtJ pathway offers a strong option for the long-term decarbonizing air travel strategy.
