Twelve Opens AirPlant One for Synthetic E-Jet Fuel Output

Cleantech firm Twelve has officially commissioned its AirPlant One facility in Moses Lake, Washington, marking a significant step in the commercialization of Power-to-Liquid (PtL) synthetic sustainable aviation fuel. The plant, which opened on June 10, 2026, utilizes a proprietary carbon transformation technology to convert captured carbon dioxide, water, and renewable electricity into E-Jet fuel. This development represents a shift away from traditional bio-based feedstocks toward synthetic alternatives.

Strategic Partnerships and Investment

The project is backed by a coalition of corporate partners, including Microsoft via its Climate Innovation Fund and Alaska Airlines through its investment arm, Alaska Star Ventures. These entities serve as both foundational investors and primary offtakers. According to Twelve, the company secured a $645 million funding round in September 2024 to facilitate the construction and scaling of this facility. The Twelve official website notes that the site's initial production phase is designed to output between 40,000 and 50,000 gallons of eSAF annually.

Regulatory Compliance and Technical Specifications

Twelve’s E-Jet fuel is certified under ASTM D7566 Annex A1, the international standard for synthetic aviation turbine fuel. This certification allows the product to function as a drop-in replacement for conventional Jet A-1 when blended up to 50%. The fuel is engineered to deliver up to a 90% reduction in lifecycle CO2 emissions compared to fossil-based fuels. Because the production process relies on renewable power rather than crude oil, the fuel’s long-term cost structure is expected to be anchored to renewable power purchase agreements. The Microsoft Climate Innovation Fund highlights that this investment supports the company's broader efforts to reduce its Scope 3 business travel emissions through book-and-claim accounting models.

E-Jet Fuel vs. Conventional Jet Fuel

The Economic Challenge of Synthetic Fuels

While the opening of AirPlant One provides a proof-of-concept for synthetic fuels, industry analysts suggest that significant hurdles remain regarding price parity. Current estimates indicate that Power-to-Liquid eSAF is five to 10 times more expensive than conventional jet fuel. The scalability of the technology will depend on reducing the energy intensity of the electrolysis process and securing consistent, low-cost renewable power. Historically, the LanzaJet Freedom Pines Fuels facility, which opened in January 2024, demonstrated the successful U.S. commercialization of next-generation SAF pathways, providing a precedent for the operational challenges Twelve now faces as it moves into the production phase.

What Comes Next: Alaska Airlines Integration

Alaska Airlines is expected to operate its first commercial domestic flight using fuel produced at the AirPlant One facility by mid-to-late 2026. This milestone will test the logistics of blending and distributing synthetic fuel within existing airport infrastructure. As the facility scales, the increased demand for electricity will also place new requirements on the Pacific Northwest power grid to support the energy-intensive electrolyzers required for commercial-scale production.

Why This Matters for Corporate Sustainability

For corporate entities, the emergence of synthetic SAF provides a critical tool for addressing Scope 3 emissions. By utilizing book-and-claim accounting, companies can purchase the environmental attributes of the fuel produced at AirPlant One to offset their corporate travel footprint. This creates a market-driven incentive for airlines to procure higher-cost synthetic fuels, effectively bridging the price gap between conventional kerosene and next-generation alternatives until production volumes achieve greater economies of scale.
