How Our PtL Platform Works
Each GECS Power-to-Liquid facility comprises seven integrated process units designed for optimal efficiency, manufactured as standardized modules for rapid deployment.
SOEC Co-Electrolysis
High-Temperature Steam & CO2 Electrolysis
Co-Electrolysis of CO₂ and Steam
In electrolysis mode, the Solid Oxide Electrolysis Cell (SOEC) systems perform co-electrolysis of carbon dioxide and steam to produce synthesis gas with an optimal 2:1 H₂/CO ratio for Fischer-Tropsch synthesis. The high operating temperature enables thermal integration that significantly improves overall efficiency compared to low-temperature electrolysis technologies.
Each SOEC unit is deployed in modular 20MW segments, providing operational flexibility and enabling phased capacity deployment. The modular architecture facilitates maintenance scheduling, allows partial operation during maintenance, and enables capacity expansion matched to market demand.

SOFC CHP Systems
Combined Heat & Power Generation
Self-Powered Electrolysis
The SOFC CHP systems provide all electrical power required for SOEC operation through a direct DC connection that eliminates AC-DC-AC conversion losses. Each 150MW SOFC installation comprises five 30MW modules, achieving industry-leading 55% electrical efficiency and 90% total CHP efficiency per module.
The thermal output from the SOFC systems is captured and recycled throughout the facility for steam generation, feedstock preheating, and process heating applications. This integrated thermal management approach maximizes overall system efficiency while minimizing external energy requirements.

Fischer-Tropsch Synthesis
Advanced Microchannel Reactors
Advanced Hydrocarbon Synthesis
GECS leverages advanced microchannel Fischer-Tropsch reactor technology for hydrocarbon synthesis due to its superior performance characteristics, commercial readiness, and modular design. The reactor achieves significantly higher reaction rates than conventional FT reactors through enhanced heat and mass transfer in microchannel architectures.
The modular FT reactor system arrives at the construction site as pre-assembled, tested units that can be installed and commissioned within weeks. This contrasts with conventional FT installations that require extensive on-site fabrication and months of commissioning activities. Each plant includes five modular FT reactor trains sized for 20MW SOEC output each.

Renewable CO2 Feedstock
Carbon-Negative Feedstock
Each GECS facility includes a Direct Air Capture (DAC) plant manufactured and operated by a GECS subsidiary. The DAC system provides renewable CO2 feedstock for SOEC co-electrolysis, with the balance sourced from industrial biogenic CO2 sources such as ethanol plants and anaerobic digesters.
The integration of DAC technology positions GECS to meet the most stringent regulatory requirements for SAF carbon intensity, including the EU ReFuelEU Aviation regulation. DAC-sourced CO2 qualifies as a renewable feedstock under EU sustainability criteria, enabling GECS eSAF to meet the highest standards for carbon accounting and achieve best-in-class carbon intensity scores.
