GASTLY

Introduction

Many essential products used in daily life, such as fuels, cleaning agents, fertilizers, and chemical intermediates, rely on syngas (a mixture of hydrogen and carbon monoxide) as a key building block. Today, syngas is mainly produced from fossil fuels, leading to high energy consumption, significant CO₂ emissions, and dependence on imported resources. This fossil-based approach conflicts with climate goals and exposes industries to supply and price volatility. At the same time, valuable local and renewable resources  remain underutilized. The GASTLY project addresses this challenge by rethinking how syngas is produced, investigating a lower carbon alternative for the chemical industry and society at large.

Goal

The main goal of GASTLY is to enable the production of low carbon syngas using renewable, locally available resources instead of fossil fuels. The project aims to demonstrate that syngas derived from biogenic CO₂, biomethane, and biogenic carbon can serve as a more sustainable substitute in existing chemical production routes. By doing so, GASTLY seeks to reduce CO₂ emissions, improve resource efficiency, and support chemical manufacturing decarbonization pathways. A key objective is to ensure that this transition is economically viable and compatible with current industrial infrastructure.

Approach

GASTLY brings together Aquafin, D-CRBN, and Eastman to pioneer a breakthrough pathway for transforming biogenic CO₂ and biomethane into syngas, low carbon methanol, and downstream chemicals. At its core, the project builds a new value chain that links wastewater treatment, plasma-based CO₂ conversion, and more sustainable chemical production. Using advanced plasma technology, renewable feedstocks from biogas are converted into low carbon syngas, which can be directly integrated into existing chemical plants and further processed into methanol and methylamines. By focusing on compatibility with current industrial infrastructure rather than building new production systems, the approach reduces technical and financial risks while accelerating large-scale industrial adoption.

Expected impact and valorization

GASTLY is expected to deliver significant environmental benefits by lowering CO₂ emissions and reducing reliance on fossil-based syngas. The project supports the circular economy by turning waste streams from wastewater treatment and sludge processing into valuable chemical feedstocks. Economically, it strengthens local value chains and improves resilience against global energy market fluctuations. The results will be valorized through industrial deployment, retrofitting existing assets, and the production of more sustainable chemicals such as low carbon methanol and methylamines. In the longer term, GASTLY can stimulate further research and open new markets for low-carbon chemical solutions.
