Technology and Project Status

SynDX assesses its core chemical-looping reverse water-gas shift technology at TRL 4, based on validation of the process, oxygen-carrier material and reactor concept in an integrated laboratory environment.

The technology has been tested in a high-temperature packed-bed reactor using approximately 1 kg of pelletised oxygen-carrier material at temperatures between approximately 620 and 820 °C.

Published Newcastle University research reports CO₂-to-CO conversion above 90% under optimised counter-current laboratory conditions, compared with 45% for conventional co-current operation in the same reactor. These results apply to the specified experimental configuration and do not represent guaranteed performance at pilot or commercial scale.

The broader counter-current chemical-looping reactor platform has also been investigated at kilogram and sub-pilot scale in a high-temperature, pressurised facility incorporating automated gas switching, heating, product-gas analysis, condensation and process controls. This related work supports the underlying reactor and scale-up knowledge but does not constitute a demonstration of a complete SynDX eSAF pathway.

SynDX’s proposed development pathway towards TRL 7 includes:

  • Increasing reactor throughput and oxygen-carrier inventory

  • Extended testing of material durability, heat management and gas switching

  • Design and commissioning of an integrated pilot unit

  • Operation with representative CO₂ and renewable-hydrogen feedstocks

  • Integration with Fischer–Tropsch, methanol or other downstream synthesis processes

  • Process modelling, techno-economic assessment, pre-FEED and HAZID

  • Pre-commercial demonstration in an operationally representative industrial environment

The intended TRL 7 milestone is to generate the performance, reliability and cost evidence required for subsequent commercial deployment and technology licensing.

Relevant results from the underlying Newcastle University research have been published in the Journal of CO₂ Utilization. Related validation of the broader counter-current chemical-looping reactor platform has been published in Energy Conversion and Management.

Collaboration Context

SynDX may be relevant for organisations across the eSAF and Power-to-Liquid value chain, including:

  • eSAF and PtL project developers

  • Synthetic-fuel producers

  • Captured-CO₂ suppliers and carbon-utilisation projects

  • Renewable-hydrogen and electrolyser partners

  • Fischer–Tropsch and methanol-technology providers

  • Engineering, EPC and plant-integration companies

  • Reactor, materials and process-equipment specialists

  • Applied research and pilot-plant organisations

  • Industrial demonstration sites

  • Investors and public funding organisations supporting technology scale-up


SynDX is particularly interested in cooperation with downstream synthesis providers, engineering companies and project developers capable of supporting pilot integration, syngas-compatibility testing and the transition from laboratory validation towards an industrially representative demonstration.

Company Overview

Syngas Dynamics Ltd, trading as SynDX Tech, is a UK technology company developing chemical-looping processes for converting captured CO₂ and hydrogen into CO-rich syngas for downstream synthetic-fuel production.

The company was established in 2026 to commercialise technologies originating from research led by Professor Ian Metcalfe and Dr Yongliang (Harry) Yan within Newcastle University’s School of Engineering. Syngas Dynamics Ltd is registered in England and Wales under company number 17240268.

The underlying technology base includes experimental data, reactor and process know-how and relevant patent rights developed through research at Newcastle University. SynDX and the University are currently completing the associated spin-out and licensing arrangements, with an exclusive worldwide licence forming the intended commercialisation basis.

Role in the eSAF Ecosystem

SynDX operates at the interface between renewable hydrogen and captured CO₂ supply and the downstream production of synthetic fuels.

Its chemical-looping reverse water-gas shift technology is being developed to produce CO-rich syngas with a controllable composition for integration with Fischer–Tropsch, methanol and other catalytic synthesis pathways.

Syngas production is a central process step because its composition, conversion efficiency and conditioning requirements can influence downstream reactor performance, energy consumption, equipment scope and overall fuel-production costs.

Within the eSAF Alliance, SynDX is represented as an emerging syngas-conversion technology developer. The company is not currently presented as an operating eSAF producer or as the provider of a commercially demonstrated, fully integrated eSAF production system.

Relevance for Europe’s eSAF Scale-up

Industrial eSAF production requires reliable pathways for combining renewable hydrogen with sustainable carbon sources. In many Power-to-Liquid configurations, this involves producing syngas with a suitable hydrogen-to-carbon-monoxide ratio before its downstream conversion into methanol or synthetic hydrocarbons.

Conventional reverse water-gas shift processes react hydrogen and CO₂ together in a single reactor. Their conversion can be constrained by thermodynamic equilibrium, potentially increasing the need for gas recycling, compression, cooling and CO₂ separation.

The SynDX process separates the conversion into two alternating redox steps using a reusable solid oxygen-carrier material. During reduction, hydrogen removes oxygen from the material and forms water. During oxidation, CO₂ replenishes the oxygen and is converted into carbon monoxide.

By separating these reactions, SynDX aims to achieve high single-pass CO₂ conversion and greater control over the resulting syngas composition. Depending on the final plant configuration, the process has the potential to reduce some of the recycle and gas-conditioning requirements associated with conventional RWGS systems.

These potential advantages remain subject to successful scale-up, extended operation and integration with downstream fuel-synthesis processes under representative industrial conditions.
