Carbon Capture Systems

Capture CO2 and produce bioCO2. HyGear supplies Carbon Capture Systems for capturing CO2 from flue gases, or other carbon dioxide containing streams, and producing sustainable CO2. Utilizing the modular and compact carbon capture technology of HyGear, CO2 from flue gases is captured and converted into continuous liquefied or gaseous CO2 generation. This enables any process that produces flue gases to reduce CO2 emissions, paving the way for carbon-neutral or carbon-negative hydrogen production. 

Carbon Capture from flue gases

HyGear’s carbon capture system to capture CO2 from flue gases is distinguished by its plug-and-play design and effectiveness. The system is capable of processing up to 2,000 Nm3/h of flue gas, extracting CO2, and purifying it to concentrations exceeding 98%. 

Its modular, prefab, and contanerized design enables the provision of cost-effective solutions while remaining adaptable to project-specific conditions. Offering a highly-efficient carbon capture technology, HyGear ensures that CO2 from flue gases is effectively captured and converted into liquid or gaseous CO2. 

One of the standout features of HyGear’s carbon capture system is its versatility. While it seamlessly integrates with HyGear’s Hy.GEN systems, for low carbon or sustainable biohydrogen production, it is also designed with the flexibility to connect to any other flue gas source. This adaptability is key for organizations aiming to reduce their carbon footprint. 

Additionally, HyGear’s carbon capture technology offers various downstream processing options for the captured CO2. Depending on specific needs, the CO2 can be liquefied using advanced CO2 liquefaction technology for take-off via a tube connection and directly utilized in various applications or it can be compressed with gaseous CO2 as valuable end-product. 

Carbon Capture Technology 

HyGear’s Carbon Capture system is based on a proven and optimized carbon capture technology: Vacuum Swing Adsorption (VSA). Adsorption technology is based on the property of adsorbents to bind different species and is able to release these species as well. HyGear also offers Carbon Capture systems with amine-based technology, excellent for post-combustion carbon capture application. 

The modular and compact, containerized carbon capture units with robust and high-quality components are available in a large range and both technologies offer the flexibility to deliver CO2 in a gaseous form or be integrated with an in-house developed CO2 liquefaction system to provide liquid CO2.


Carbon negative hydrogen and biohydrogen  

Producing (bio)hydrogen on-site using HyGear’s Steam Methane Reforming (SMR) technology, and utilizing the hydrogen right where it is made, eliminates the need for transportation and the emissions that come with it. HyGear’s hydrogen generators can work with renewable natural gas (RNG), also known as biomethane, derived from upgrading biogas that comes from biomass materials or organic residues, to produce hydrogen. In the case of on-site hydrogen production, this results in a carbon negative hydrogen or. When using biomethane to produce hydrogen this is also known as biohydrogen. 

Carbon dioxide (CO2) applications  

CO2 captured through carbon capture technology has a range of applications that can contribute to various industries: 

Direct Use: 

  • Food and Carbonated Drinks: Captured CO2 can be utilized in the carbonation of beverages such as sodas, as well as in food preservation to maintain freshness. 
  • Horticulture: In greenhouses, CO2 is used to promote plant growth by increasing the concentration of carbon dioxide in the greenhouse. 
  • Dry Ice: Captured CO2 can be compressed and cooled to form dry ice, which is used for cooling and refrigeration purposes. 
  • Enhanced Oil Recovery: Injecting CO2 into oil wells can help in extracting more oil from the reservoir. 


  • Gas Fields & Aquifers: Captured CO2 can be stored in depleted natural gas fields or deep saline aquifers to prevent it from entering the atmosphere. 
  • Oil Fields: Similar to gas fields, CO2 can be stored in depleted oil fields, where it also serves the dual purpose of enhanced oil recovery. 

Chemical & biological transformation: 

  • Synthetic Fuels: Through chemical processes, captured CO2 can be converted into synthetic fuels such as methanol or diesel. 
  • Organic Chemistry: In organic chemistry, CO2 is used as a raw material for the production of chemicals such as urea, salicylic acid, and others. 
  • Polymers & Plastics: CO2 can be used in the production of polymers and plastics, serving as a feedstock for certain chemical reactions. 
  • Methanation: Captured CO2 can be converted into methane through a process called methanation, which can be used for energy generation or as a raw material in various industrial processes. 


Carbon Capture and Localized CO2 Production  

Localized CO2 production through HyGear’s Carbon Capture Technology offers a dual benefit – reduction in transportation costs and further mitigation of carbon footprints. With CO2 being a critical commodity in various industries, localized production using a carbon capture system is both economically and environmentally advantageous. CO2 liquefaction to produce liquid bioCO2 can create an extra source of revenue, reduce carbon emissions, and increase independence of CO2 buyers and consumers.
