CHICAGO, IL — On March 13, 2025, Syntholene Energy Corp unveiled a groundbreaking step toward revolutionizing clean aviation fuel with a binding agreement securing up to 20 megawatts of geothermal energy. This deal powers the world’s first geothermally-driven synthetic sustainable aviation fuel (eSAF) commercial demonstration facility, heralding what the company calls “the era of low-cost synthetic fuel.”

Syntholene’s innovative approach marries geothermal heat and electricity to drive high-temperature steam electrolysis, slashing energy costs for eSAF production. Targeting synthetic kerosene as its first output, the facility addresses the aviation sector’s growing appetite for carbon-neutral fuels that seamlessly substitute fossil-based kerosene without infrastructure changes. Lab-scale success now scales to this demonstration plant, with plans for industrial expansion contingent on technical and financial viability.

“This energy agreement represents the seeds of a transformative moment for synthetic fuel cost and scalability.” — Dan Sutton, CEO, Syntholene Energy Corp

Dan Sutton, Syntholene’s CEO, emphasized the transformative potential: “This energy agreement represents the seeds of a transformative moment for synthetic fuel cost and scalability.” By tapping geothermal resources—offering consistent, carbon-neutral heat and power—the company aims to undercut fossil fuel prices while delivering high-performance eSAF. The binding Letter of Intent (LOI) with a geothermal site partner grants Syntholene full control over the facility’s equipment and IP, plus an option for 20MW of future capacity.

Unlike traditional geothermal plants focused on electricity, Syntholene optimizes waste heat for fuel synthesis, enhancing efficiency. This hybrid model could redefine power-to-fuels economics, supporting aviation’s decarbonization without sacrificing existing infrastructure worth trillions. With scalability baked into the agreement, Syntholene eyes a modular system to meet global clean fuel demand.
