A proven Norwegian carbon capture system with no harmful chemicals without need for heat

Challenges & Triggers

Global industries emit nearly 38 billion tonnes of CO₂ annually, with record atmospheric CO₂ concentrations hitting ~422 ppm—underscoring the urgent scale of the challenge

Without effective solutions, industries face mounting regulatory pressures, rising costs, and reputational risks that threaten long-term competitiveness

The growing momentum among governments and industries to reduce carbon emissions and embrace circular economies rapidly accelerates the demand for CO₂ reduction technologies and solutions

Solution

OGL delivers a chemical-free, low-energy and fully electric carbon capture solution. It is robust to real-world pollutants, integrates easily with existing operations, and does not rely on residual heat - making it ideal for hard-to-abate sectors. OGL enables clean, efficient decarbonization across key industries such as lime, cement, and waste-to-energy - helping decarbonize global value chains

Proven technology with clear roadmap to best-in-class capture cost

Improvements from industrial pilot until today

• Control system developed for safe, autonomous operations
• Optimized process kinetics through targeted process optimization and materials technologies
• Digital tools:
  • Data capture to cloud
  • On-demand visualization
  • Dashboard livestreaming KPIs

• Introduction of energy recuperation tools:

• Francis turbine
• Turboexpander

Anticipated further improvements going forward

• Continued optimization through materials and process technologies
• Optimization of energy recuperation methods
• Live automatic process optimization by enhanced control system
• Successful introduction of the c-Pump has potential to reduce net electricity consumption to close to zero if sufficient waste heat and cooling is available

Proven, 100% clean, autonomous and energy efficient carbon capture

Innovative and energy efficient closed-loop water-based CO² capture process

Comments :

Wet scrubber (Preconditioning)

• Initial cooling and scrubbing of the flue gas to remove unwanted particles and chemicals
• Primarily based on standard wet scrubber technology
• Efficient handling of pollu tants

Absorpt ion

• A physical process of absorbing the CO² from the flue gas in a water-based liquid
• As the gas rises in the absorption column, it meets fresher liquid allowing for efficient uptake of the CO² component in the gas
• Relies on proprietary IPR to achieve continuous high CO₂ concentration and stable solvent absorption capacity

Desorption

• Through low-pressure stripping and proprietary OGL techniques, the CO₂-rich liqu id phase is regenerated and reused for sustained CO₂ capture
• OGL's proprietary IPR facilitates rapid and cost-efficient CO₂ stripping, by improving the desorption kinetics (reducing the energy consumption), including the use of advanced materials technologies setting it apart from other phy sical methods
• Use of a proprietary control sy stem to optimize the process, inclu ding handling of process variations

Energy recovery

• The CO2-rich liqu id is depressurized through a Francis turbine
• A turboexpander is used to convert pressure energy into mechanical work

Digital infrastructure

• The capture sy stem is supported by a comprehensiv e digital infrastructure, including autonomous cloud-based operations
• Supported by real-time data integration Model Predictive Control is currently in development to enable self-optimizing operations and system performance

Addition of c-Pump can reduce net electricity demand by >80%

Comments :

• If suffi cient waste heat and cool ing i s available, the c-Pump can be integrated in the facility by replacing the compressor, effectively reducing the net electricity demand to close to zero
• The c-Pump is a heat engine, utilizing heat differences, taking the waste heat and turning it into mechanical energy to compress the flue gas
• Facilities in areas with limited grid capacity can benefit from implementation of the c-Pump by significantly redu cing their electricity need
• Could potentially connect a generator between the wet scrubber and the c-Pump to achieve the exact pressure needed for the c-Pump to generate su fficient mechanical energy, and generate electricity in the process
• The capex of the c-Pump is expected to be comparable to the capex of the compressor
• Building on our established commercial partnership with Herøya Industry park, we intend to jointly explore and initiate pilot testing activities on the c-Pump during 2026

c-Pump: Can be used where excess waste heat and cooling is available

poten tially have a net electricity demand of approximately 25 kWh per tonne, dependin g on the energy recovery from the c-Pump
