Nuclear-Derived Sustainable Aviation Fuel

Eq.flight combines Direct Air Capture, high-temperature electrolysis, CO₂ conversion and hydrocarbon synthesis into a single Power-to-Liquids SAF pathway. It links hydrogen production, syngas conditioning, Fischer–Tropsch synthesis and upgrading to maximise SAF yield from low-carbon energy inputs.

The Eq.flight stack is built around proven industrial unit operations, configured for repeatable deployment. It turns captured CO₂ and water into drop-in jet fuel through integrated electrochemical and catalytic processing steps.

Eq.flight is optimised to use nuclear electricity and steam, prioritising continuous energy availability and maximum use of thermal inputs. Direct heat integration avoids inefficient heat-to-power-to-heat conversion, improving whole-system efficiency and supporting stable SAF output with strong lifecycle carbon intensity.

Nuclear coupling enables Eq.flight to avoid storage and backup generation requirements. Firm electricity and steam provide predictable operating conditions, improving utilisation and reducing exposure to interruptions that increase cost and downtime.

Solid oxide electrolysis is Eq.flight’s sole hydrogen production route. By using high-temperature steam, SOEC reduces electrical energy demand and can deliver 20–30% electricity savings versus PEM or alkaline electrolysis, improving overall PtL efficiency.

SOEC has the strongest case for nuclear heat integration because steam input directly improves performance. Eq.flight targets steady-state operation to enhance efficiency and mitigate degradation risks associated with thermal cycling.

Eq.flight incorporates Direct Air Capture to provide atmospheric CO₂ as a feedstock for synthetic fuel production. Solid-sorbent DAC requires low-temperature heat for desorption, which can be supplied efficiently as low-pressure steam from a reactor secondary circuit, reducing electrical heating demand.

DAC enables Eq.flight to decouple CO₂ supply from point-source emissions. By integrating captured atmospheric CO₂, the system supports scalable, repeatable SAF production and strengthens lifecycle carbon intensity credentials.

Fischer–Tropsch synthesis converts conditioned syngas into liquid hydrocarbons, forming the basis of drop-in SAF production. The FT reaction is exothermic and provides recoverable heat, which Eq.flight can reuse across the plant to reduce external heating loads and support efficiency.

Eq.flight’s FT stage sits downstream of RWGS, enabling tight heat and material integration. Continuous operation improves stability, extends catalyst life, supporting consistent product quality and predictable output.

Eq.flight’s competitive advantage is in integration: managing multi-vector nuclear heat and electricity inputs, controls, interfaces and operational constraints across the full PtL stack. The system is designed for constant running, simplified operation and maximum product output, reducing reliance on storage and backup systems.

Integration focuses on making the plant operate like a baseload industrial asset. Heat recovery, steam networks, and stable utilities reduce cycling and downtime, producing validated performance data to de-risk future FOAK nuclear-collocated plants.
