Bill Gates’ Breakthrough Energy Backs Low-Cost Synthetic Jet Fuel Platform Lydian

Synthetic aviation fuel technology company Lydian announced that it has raised $43 million in a Series A funding round, with proceeds aimed at supporting the launch of its platform enabling the delivery of cost-competitive jet fuel with a 95% lower carbon footprint.

The new financing round was led by Bill Gates-founded Breakthrough Energy Ventures, marking the first announced deployment from its oneworld BEV Fund, launched last year in partnership global airline alliance oneworld and a group of airlines to accelerate the global development of long-term sustainable aviation fuel (SAF) solutions to address the limited availability and high cost of SAF.

Carmichael Roberts, Managing Partner at Breakthrough Energy Ventures, said:

“Decarbonizing aviation will require advanced fuels that compete on cost, work within today’s aviation infrastructure, and deliver the performance flyers and airlines expect. Lydian is taking on that challenge with a purpose-built approach to synthetic aviation fuel production.”

Founded in 2021, Cambridge, Massachusetts-based Lydian develops modular synthetic fuel production technology and turnkey plants that produce sustainable aviation fuel from captured CO₂, hydrogen and renewable electricity.

The company said that, unlike conventional synthetic fuel projects that adapt legacy gas-to-liquids technologies into large, bespoke plants, its PIVOT platform was purpose-built for low-cost renewable electricity and modern power markets. The platform integrates proprietary reactor technologies, catalysts, process design, software and balance-of-plant into standardized, factory-built modules designed to reduce project complexity while improving economics.

According to the company, the platform is designed to shorten project development timelines by up to two years through pre-engineered modules, operate flexibly alongside intermittent renewable power to reduce electricity costs, produce drop-in sustainable aviation fuel with up to 95% lower lifecycle greenhouse gas emissions, and provide a pathway toward cost-competitive synthetic aviation fuel at commercial scale.

Lydian said that its platform reduces plant capital costs by more than 50% compared to competing technologies and creates a commercially viable pathway for synthetic fuels to compete with biofuels on price within this decade.

The company is currently operating a ton-scale pilot plant at its Boston-based R&D Center of Excellence and is advancing a commercial demonstration facility targeted for operation in 2028, with its first full-scale commercial deployment expected in 2030.

Joe Rodden, CEO and Co-founder of Lydian, said:

“PIVOT represents a fundamentally different approach to synthetic fuel production. By designing every part of the system for lower capital costs, greater operational flexibility, and faster deployment, we’ve created a platform for commercially competitive synthetic fuel projects. This financing gives us the resources to bring that vision to market.”

Additional investors participating in the funding round included AP Ventures, Builders Vision, alongside existing investors including Congruent Ventures, Galvanize, Grok Ventures, Overture, Union Square Ventures, and Voyager Ventures.
