What Lydian does
Lydian Labs, Inc. is a Massachusetts-based climate technology company developing synthetic aviation fuel from CO2, hydrogen, and renewable electricity using a proprietary electric reactor platform. The core process captures CO2 and combines it with hydrogen (produced via water electrolysis or other low-carbon pathways) into syngas, which is then synthesized and upgraded into ASTM-approved Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK), a drop-in sustainable aviation fuel (SAF) targeting up to 95% lifecycle emissions reduction versus conventional jet fuel.
The company's technology proposition is integrated: all required subsystems and balance of plant are developed in-house and supplied as a single modular package, with claimed ≥50% lower capital cost, 30-50% lower energy consumption, and a 10-100% dynamic operating range enabling direct use of intermittent renewable power. Lydian operates two product lines — Direct SAF Supply for airlines, fuel buyers, and corporate offtakers, and Turnkey Production Plants for owners and operators of synthetic fuel facilities — targeting commercial-scale demonstration by 2027 and commercial volumes from 2028.
Lydian is a venture-backed private company headquartered in Charlestown, MA, with a 25,000 SF R&D Center of Excellence at Hood Park and a lean 11-50 person engineering team. Total disclosed funding is approximately $56M, anchored by Congruent Ventures and Galvanize Climate Solutions at seed and supplemented by a ~$44M round in January 2026. GTM is enterprise field sales into airlines, fuel distributors, and corporate offtakers, supported by participation in programs such as the IAGi Accelerator (2025) and policy-aligned regional SAF hub initiatives with Massport.

Lydian competitors and assessment
Company assessmentDirect peers
- Aemetis: Aemetis is developing and producing low-carbon renewable fuels including SAF via alcohol-to-jet and other pathways at commercial scale. Competes with Lydian for the same airline SAF procurement dollars.
- Twelve (formerly Opus 12): Twelve uses CO2 electrolysis to produce sustainable aviation fuel and chemicals. Directly comparable as a CO2-to-jet-fuel pathway player backed by significant capital ($645M+ raised).
- Infinium: Infinium produces power-to-liquids e-fuels including e-SAF from CO2 and green hydrogen using reverse water-gas-shift and Fischer-Tropsch synthesis — the most direct technological and product overlap with Lydian.
- INERATEC: INERATEC builds compact Fischer-Tropsch reactors to produce e-fuels including e-kerosene from CO2 and green hydrogen. Shares Lydian's FT synthesis pathway and modular reactor design philosophy.
- HIF Global: HIF Global is developing e-fuels including e-SAF using wind power and CO2-derived synthetic fuels, with its Haru Oni project in Chile. Directly competes with Lydian in the synthetic jet fuel category.
- Norsk e-Fuel: Norsk e-Fuel is building a commercial-scale e-SAF plant in Mosjøen, Norway, using renewable power, green H2, and CO2. Targets similar ASTM FT-SPK fuel output as Lydian for European aviation customers.
- SkyNRG: SkyNRG is a SAF-focused company building the supply chain for sustainable aviation fuels, including technology investments in synthetic and biofuel pathways. Direct competitor in the SAF supply market Lydian targets.
- LanzaTech: LanzaTech produces SAF via gas-fermentation-to-ethanol followed by alcohol-to-jet conversion. A direct competitor in the synthetic SAF market with at-scale technology, listed on Nasdaq.
Broad incumbents
- Neste: Neste is the global leader in HEFA-based SAF (My Renewable Diesel/SAF) with multi-billion-dollar revenues and existing refinery-scale production. Broad incumbent that competes with Lydian for SAF mandate volume but via a fundamentally different pathway.
Emerging players
- DG Fuels: DG Fuels is developing cellulosic ethanol-to-jet SAF plants with multi-billion-dollar offtake commitments. An emerging competitor targeting the same e-/bio-SAF market that Lydian addresses.
