Frequently Asked Questions

EnEarth is a Greek-based carbon storage and environmental services company, focused on decarbonisation in Southeast Europe. Its mission is to transform depleted oil & gas fields into secure geological storage sites for CO₂, repurposing existing infrastructure to build “green hubs.”

  • Carbon storage refers to injecting captured or removed CO₂ into underground geological reservoirs such as depleted oil & gas fields or deep saline aquifers so that the CO₂ is stored long-term and prevented from entering the atmosphere.
  • Location: Prinos field, Northern Greece.
  • Oil-producing field, now being repurposed for CO₂ storage.
  • Phase 1 Goal: Inject up to 1 million tonnes CO₂/year.
  • Phase 2 Goal: Scale up to 2.8 million tonnes CO₂/year.
  • Long-term capacity: Potential storage of up to 66 million tonnes by 2050.
  • License: 25-year CO₂ storage license term.
  • Geological suitability for safe injection and storage.
  • Strategic positioning for serving hard-to-abate industries in Greece and the Mediterranean.
  • Ability to reuse existing infrastructure, reducing costs and risks.
  • RepAir: Partnership for Direct Air Capture (DAC) and CO₂ injection.
  • Prime Marine: Partnership for CO₂ shipping and transport logistics.
  • Storage project and DAC expected to begin in 2027. Injection capacity projected to reach 2.8 Mt CO₂/year from 2030 and onward.
  • €120 million from the Connecting Europe Facility (CEF).
  • €75 million from Greece’s Recovery & Resilience Facility
  • €75 million from other national sources.
  • Recognised as a Project of Common Interest (PCI) by the EU.
  • Yes, EnEarth has submitted an Environmental Impact Assessment (EIA) for Phase 1 that has been awarded an Environmental Permit by the Ministry of Environment and Energy of Greece.
  • Comprehensive environmental and social monitoring plans are included.
  • Permanent geological storage for CO₂ from hard-to-abate sectors.
  • Supports decarbonisation and net-zero targets.
  • Cost-effective through reuse of existing infrastructure.
  • Nikolas Rigas is Head of Carbon Storage.
  • EnEarth is part of the Energean Group, with long-standing oil & gas expertise.
  • CO₂ will be transported via shipping, in compressed or liquid form by specifically licenced companies.
  • Partnerships enable efficient transport from emitters to Prinos.
  • Develop green hubs in northern Greece.
  • Expand storage to other Mediterranean sites.
  • Support the decarbonisation value chain across the region.
