Heidelberg Materials Devnya JSC and ENEARTH LIMITED Forge Strategic Partnership for CO₂ Transport and Storage in Bulgaria

Heidelberg Materials Devnya JSC and ENEARTH LIMITED, a subsidiary of the Energean Group, have signed a strategic cooperation agreement to jointly develop infrastructure for the transport and permanent storage of carbon dioxide (CO₂) in Bulgaria. This collaboration marks a significant step toward advancing carbon capture and storage (CCS) solutions in Southeastern Europe.

Under the agreement, EnEarth will assume the role of Storage Operator within the Devnya CO₂ project, which focuses on building a dedicated pipeline and establishing an onshore geological storage facility in the Varna region. The initiative forms a critical component of Heidelberg Materials’ ANRAV CCUS project, designed to become the first fully integrated carbon capture, utilization, and storage (CCUS) system in Eastern Europe.

The ANRAV project aims to capture approximately 800,000 tonnes of CO₂ annually from Heidelberg Materials’ cement plant in Devnya and transport it for safe, permanent storage near the site. Supported by funding from the EU Innovation Fund, this project underscores the commitment of both companies to industrial decarbonization and climate neutrality.

With the signed Term Sheet, Heidelberg Materials and EnEarth will collaborate on technical development, permitting, and stakeholder engagement to advance the project through Final Investment Decision (FID) and into commercial operation. Subject to timely regulatory approvals, the storage facility is expected to be operational by 2029.

Nikolas Rigas, Head of Carbon Storage at EnEarth, commented:

“Today represents a pivotal moment for EnEarth as we expand into Bulgaria and strengthen our role in delivering large-scale decarbonization solutions for hard-to-abate sectors across Southeastern Europe and the Eastern Mediterranean. Heidelberg Materials’ confidence in our expertise, proven through the Prinos CO₂ storage project, is a testament to our capabilities. Together, we will ensure the successful implementation of the Devnya CO₂ project, creating value for the environment, industry, and local communities.”

Mihail Polendakov, Executive Director of Heidelberg Materials Devnya, added:

“We are proud to welcome EnEarth as our partner for the Transport & Storage component of the Devnya CO₂ project. Their experience and success with the Prinos CCS project in Greece will bring efficiency and innovation to ANRAV CCUS. This partnership is a major step toward achieving our sustainability objectives and delivering long-term benefits for business, society, and the environment.”
