Result description
This reflects the high implementation potential of CEEGS in carbon capture and storage (CCS/CCUS) projects, with applications across carbon-intensive industries. The CEEGS system, as a scalable technology for geological CO₂ storage, has the potential to be adaptable across various geological contexts and to contribute directly to climate-neutrality strategies. The detailed integration with salt cavities and porous media, and the modelling and testing of CO₂ storage in salt formations and porous media, enable further implications for scalability and site selection. Furthermore, a screening and ranking methodology tailored to the needs of CEEGS was developed. The geological integration concept has been identified as patentable, and a European patent has been submitted. Lastly, the evaluation of geological replicability using multicriteria analysis across different EU regions (Germany, Spain) enables future selection of sites with different properties.

R&D, Technology and Innovation aspects
CEEGS developed a scalable system utilising CO₂ for power, heat, and cooling, and partial CO₂ sequestration, turning surplus renewables into storable thermal energy for on-demand use. A 20 kWel demo raised the tech from TRL2 to TRL4 with EU validation, offering low cost, long duration, and rare-earth independence. Next: demo plant and business plan to reach TRL6.
• Applications from few tpa to several Mtpa of CO2 storage capacity,
• Flexible energy storage duration from hours to weeks,
• Modular construction possible
• Adaptable power ratings
• Standardisation potential
·Modular system design,
·Easy to scale up or down based on local energy demand and storage needs,
·Connection of renewable power plants, industrial CO₂ sources, including cleaning, as a source of the CO2 and a possible user of the stored energy, or heating/cooling networks without major redesign,
·store excess electricity from any source, improving grid stability in various energy mixes,
·CO₂ injection, geothermal heat extraction, and underground storage already have industrial analogues in oil & gas, CCS (Carbon Capture & Storage), and geothermal power.
·Standardised designs for storage volume ranges, reservoir types, and power ratings can be developed, enabling faster rollouts.
• Storage technology without the use of rare earths,
• No ignition or flammability, as CO2 is an inert gas
• No toxic media used
• CO₂ sequestration – decarbonisation of hard -to-abate industry, and possibly negative emissions for sources relying on biomass for power generation, such as pulp&paper sector or waste-to-energy sector
• Excess green electricity, no backup from fossil fuel
• new value chains in renewable energy, energy storage, and CO₂ management
