Primary audience
Strategic investors
Own a defensible technology position in a critical PtX process step — with capital-light scaling and strategic M&A optionality.
Investment thesis → Secondary audienceEPC & plant builders
Integrate a standardized syngas module instead of developing the RWGS core from scratch.
Integration path → Tertiary audiencee-SAF & e-fuel offtakers
Enable scalable low-carbon fuel projects by addressing the green-syngas bottleneck upstream.
Application value →The missing process step
The e-fuel value chain needs green syngas.
Fischer-Tropsch e-fuels and e-methanol need a reliable source of syngas from renewable hydrogen and captured CO₂. Today, this conversion step is still a major technical and economic bottleneck.
RWGS+ is designed to close that gap with a highly modular microwave-plasma process that can sit between hydrogen/CO₂ supply and downstream synthesis.

The development of our innovative technology for a sustainable future is financially supported by the European Union. As part of the funded project, we aim to make an important contribution to the defossilization of industry.
In detail: refuel.green is developing a microwave-plasma reactor that converts CO₂ into green carbon monoxide (CO), an important chemical feedstock, while simultaneously treating industrial wastewater wherever possible. This innovative process enables the climate-neutral use of CO₂ as a resource, reduces greenhouse-gas emissions and breaks down contaminants in the supplied wastewater at the same time. The technology combines a simple modular design with low operating pressures and requires no catalysts, which both reduces costs and enables operation in a range of industrial applications.
The project’s objectives go beyond technical innovation: refuel.green aims to create an economically viable alternative to fossil-based processes and thereby transform the chemical industry, aviation and other hard-to-electrify sectors sustainably. The work focuses in particular on increasing the chemical conversion of CO₂ and improving electrical energy efficiency, as these are the key indicators for realizing an economically competitive product.
Implementing the project will enable refuel.green to advance its technologies to a higher technical level and prepare for market entry. With the planned market launch of modular reactors by 2029, refuel.green will play a key role in the transformation toward a CO₂-neutral industry.
This groundbreaking technology exemplifies Saxony’s innovative strength and demonstrates how companies can contribute through research and development both to achieving climate targets and to strengthening the region’s economy.
Technology edge
Built around the economics that make PtX projects work.
The RWGS+ architecture targets high conversion, low complexity, modular scaling and flexible syngas production — without a catalyst dependency.
Low CAPEX
Simplified high-temperature process and standardized hardware architecture.
Dynamic optimization
Operating strategy can respond to electricity, feedstock and market price changes.
Modular & scalable
Scale by adding standardized modules instead of redesigning the core process.
Variable syngas ratio
H₂:CO from 1:1 to above 2:1 for different downstream pathways.
Direct tail-gas reforming
Designed to accept recycled FT tail gas without separate pre-reforming.
No catalyst
Lower catalyst-related CAPEX, maintenance and replacement exposure.
NextGen design
Designed for low soot formation and reduced metal dusting risk.
Developed for EPC integration
A standardized module for industrial plants.
The technology is embodied in standardized 1 MW, 40-foot container modules designed to give EPC partners a repeatable building block for e-fuel plants.

Economics — the core USP
Targeting a ≥20% syngas cost advantage.
Under the current pitch-deck assumptions, RWGS+ targets materially lower syngas cost than state-of-the-art RWGS, co-SOEC and microwave-plasma routes.
Indicative syngas cost€/t
Pitch-deck calculation basis: €0.05/kWh electricity · €2.5/kg H₂ · €150/t CO₂ · H₂:CO = 1.8:1. Target values, not guarantees.
Capital-light business model
