Danube Carbon Storage is a full chain Carbon Capture and Storage (CCS) operation in Central Hungary. It will collect more than 500,000 tonnes of biogenic CO2 per year from the yeast fermentation and anaerobic digestion processes of Pannonia Bio, one of Europe’s largest biorefineries. The collected CO2 will be transported via pipeline and injected into a nearby permanent onshore geological storage site in a saline aquifer of the Pannonian Basin. The company will generate EU-certified carbon removal credits for the voluntary carbon markets. Europe’s existing fermentation sector has the potential for over 10 million tonnes per year of similar carbon removals using biogenic CO2. This impact could further increase as the EU biomethane sector grows.
Danube Carbon will demonstrate the first large-scale integration of bioCCS in Europe, with low CCS unit costs. The proposed CO2 storage model could also be scaled up to handle tens of millions of tonnes of CO2 across the Pannonian Basin. The company aims to set a new benchmark for economic feasibility and demonstrate strong potential for scalable expansion and replication across Europe.
Danube Carbon will deliver over 1% of Europe’s 2030 annual CO2 storage capacity target (50 million tonnes per year) mandated in the Net-Zero Industry Act (NZIA). It will also deliver more than 10% of the 5 million tonnes of annual Carbon Removals anticipated for 2030 in the 2021 Communication on Sustainable Carbon Cycles. Additionally, Danube Carbon will complement the implementation of the upcoming EU Regulation Establishing a Certification Framework for Carbon Removals by providing a substantial volume of CRCF-compliant credits, helping to accelerate the growth of Europe’s Voluntary Carbon Markets.
Danube Carbon's flagship project Danube Removals is supported by the EU Innovation Fund, under a 12 year agreement signed in April 2025.
