85% single-pass CO₂ conversion at 1 kWh(el.AC)/kg syngas.
refuel.green turns renewable H₂ and captured CO₂ into FT-, methanol- and DRI-ready green syngas — modular, catalyst-free and engineered for industrial economics.
Own a defensible technology position in a critical PtX process step — with capital-light scaling and strategic M&A optionality.
Investment thesis →Integrate a standardized syngas module instead of developing the RWGS core from scratch.
Integration path →Enable scalable e-SAF and DRI projects with a flexible, low-carbon syngas supply.
Application value →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.
The RWGS+ architecture targets high conversion, low complexity, modular scaling and flexible syngas production — without a catalyst dependency.

Based on refuel.green's calculations, RWGS+ targets materially lower syngas cost than state-of-the-art RWGS, co-SOEC and microwave-plasma routes.
Pitch-deck calculation basis: €0.05/kWh electricity · €2.5/kg H₂ · €150/t CO₂ · H₂:CO = 1.8:1. Target values, not guarantees.
EPC partners bring global project execution and customer access; refuel.green provides the core technology at very low CAPEX.
RWGS+ is positioned upstream of several large PtX value chains, creating strategic relevance beyond one single end product.
FT-ready syngas for synthetic aviation fuel projects facing rising SAF demand and quota pressure.
Flexible H₂:CO ratios support methanol-oriented PtX pathways and maritime decarbonization.
A non-fossil syngas route for chemical intermediates and drop-in production pathways.
Potential reducing gas for direct reduced iron (DRI), combining H₂ and CO in a configurable feed.
RWGS+ can use captured CO₂ from steelmaking with renewable H₂ to generate an H₂/CO mixture for a suitable DRI process.
Hydrogen supports fast ore reduction; CO also acts as a reducing agent and can contribute carbon to the iron. Unlike pure-H₂ operation, a mixed gas offers another lever for the furnace heat balance and DRI carbon content.
Gas purification, H₂ availability, the optimum H₂:CO ratio, carbon deposition, CO₂ balance and the DRI furnace design must be validated for each project. Direct use of untreated steelworks off-gas is not assumed.
