Funding, financing or cooperation for the further development of the technology to TRL 5-6.

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 kWh to several MWh storage,

• Flexible 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 possible user of the stored energy, or district heating/cooling networks without major redesign,

·store excess electricity from any source, improving grid stability in various energy mixes,

·CO₂ injection and production, geothermal heat extraction, and underground storage already have industrial analogues in oil & gas, CCS (Carbon Capture & Storage), and geothermal power.

·Standardised designs for specific storage volumes, 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
