Wedoany.com Report-Dec.14, EnEarth, a Greece-based carbon storage specialist, has signed a binding term sheet with Heidelberg Materials Devnya, the Bulgarian subsidiary of global cement producer Heidelberg Materials. Announced on 9 December 2025, the agreement grants EnEarth exclusive negotiation rights for the offshore transportation and permanent geological storage of CO2 captured at the Devnya cement plant in Bulgaria’s Varna region.

The Devnya CCUS project targets the capture of up to 800,000 tonnes of CO2 per year from the cement kiln. Captured volumes will be transported by ship to an offshore storage site developed and operated by EnEarth. The European Union has allocated a €190 million grant to the initiative, of which €38 million is specifically earmarked for storage-related infrastructure.

EnEarth, a subsidiary of London-listed Energean plc, specialises in converting depleted hydrocarbon reservoirs into large-scale carbon storage facilities. The company is building a portfolio of storage hubs in the Eastern Mediterranean and intends to offer permanent sequestration services to industrial emitters across Europe.

Heidelberg Materials operates the Devnya cement plant together with adjacent grinding, terminal and ready-mix concrete facilities in Bulgaria. The Devnya decarbonisation scheme forms part of the group's wider commitment to achieve net-zero cement production through multiple carbon capture projects worldwide.

Both parties have stated that successful delivery of the project will contribute to substantial CO2 emission reductions, create economic value, and provide benefits to local communities in the Varna region.

Full commercial agreements, including a CO2 Transportation and Storage Services contract, are now under negotiation. Subject to final investment decision and permitting milestones, the partners aim to commence injection operations before 2030, establishing one of the first fully integrated industrial-scale CCUS chains in Southeast Europe.

The collaboration combines Heidelberg Materials' expertise in large-scale carbon capture with EnEarth's offshore storage capabilities, creating a replicable model for hard-to-abate industries seeking permanent CO2 management solutions.
