Our breakthrough technology enables radically simpler and cheaper plants to produce drop-in jet fuel from CO₂. This is the Lydian difference.

Two workers in hard hats and uniforms walk past and one inspects industrial equipment behind transparent panels.

One plant, one technology.

All required subsystems and balance of plant to produce on-spec jet fuel from hydrogen and CO₂, developed in-house and supplied by Lydian.

Faster to build.

Target deployment timeline of less than 2 years, compared to 4+ for other SAF plants.

Cheaper to install.

Industry-leading capital intensity extends predictably to lower total installed cost thanks to our integrated design.

Cheaper to run.

Best-in-class dynamic range allows direct operation on intermittent renewable power, which is cheaper and easier to source.
Direct SAF supply
Turnkey production plants

Direct SAF supply for airlines, fuel buyers, and corporate offtakers.

Lydian is developing projects to produce both RFNBO-compliant e-SAF from hydrogen derived via water electrolysis as well as synthetic fuels from other hydrogen sources.

How It Works

Inputs

Captured CO₂

Collected from point sources

H₂

Produced onsite via electrolysis or other low-carbon pathways

Intermittent renewable power

Designed to ramp up and down with the cheapest renewables

Process

Syngas production

CO₂ + H₂ get converted into syngas

Fuel synthesis + Upgrading

Jet fuel molecules are synthesized from syngas

Output

SAF

Compatible with commercial and defense operability requirements
Founded in 2021 in Cambridge, MA, Lydian was built by a group of talented engineers, scientists, and operators to enable widespread sustainable flight.
