Core Competencies
Reverse Compression & Pressure Management Systems
Reverse Compression & Pressure Management Systems
High-performance compression systems enabling controlled gas reintegration between distribution and transmission networks.
Reverse compression and pressure management are no longer optional technologies — they are structural requirements in modern biomethane-integrated gas grids.
Regaco designs and delivers engineered compression solutions for regulated gas infrastructure, combining reverse compression and pressure management into fully integrated systems.
Applications include:
- DSO-to-TSO gas reintegration
- Bidirectional gas flow control
- Booster compression for pressure uplift
- Pressure stabilisation across grid levels
- Recompression of stranded gas volumes
With increasing biomethane injection into distribution networks, pressure differentials prevent natural reverse flow. Our engineered compression systems resolve this imbalance and ensure stable integration into high-pressure transmission infrastructure.
All systems are engineered for:
- Continuous-duty operation
- High availability and redundancy
- Near-zero methane emissions
- Long-term lifecycle performance
- Optimised Total Cost of Ownership (TCO)
Reverse compression is no longer optional — it is a structural requirement in modern European gas networks.
Biomethane Grid Injection Units
Biomethane Grid Injection Units
Engineered grid injection systems for safe and compliant integration of biomethane into DSO and TSO networks.
Regaco develops complete grid injection units enabling upgraded biogas (biomethane) to be injected directly into regulated gas infrastructure.
We deliver turnkey systems including:
- Metering and fiscal measurement
- Gas quality control and monitoring
- Odorisation systems
- Pressure regulation and safety systems
- Compression where required
- Integration into existing grid control systems
Our grid injection solutions are designed to comply with national and European gas grid codes and are adapted to both:
- Distribution network injection (DSO level)
- Direct transmission injection (TSO level)
By combining injection technology with compression expertise, we ensure seamless integration of renewable methane into existing gas networks.
Biogas Upgrading & CO₂ Liquefaction Systems
Biogas Upgrading & CO₂ Liquefaction Systems
Advanced upgrading and CO₂ recovery solutions in partnership with Kanadevia Inova Biomethan GmbH.
As official partner and distributor, Regaco supplies membrane and amine upgrading systems as well as integrated CO₂ liquefaction solutions.
Scope includes:
- Biomethane upgrading plants
- Integrated CO₂ liquefaction systems
- Process engineering and integration
- Feasibility and technical advisory
- Full project support from development to commissioning
These systems enable high methane recovery, optimised CO₂ utilisation and improved overall plant economics.
Unique CO₂ Inerting Concept
Unique CO₂ Inerting Concept
Proprietary CO₂-based inerting solution for safe commissioning of biogas reactor tanks and process systems.
Regaco has developed a unique engineered concept for controlled inerting of newly constructed biogas reactor tanks and associated process volumes during commissioning and start-up.
Traditional inerting methods can involve operational complexity, safety risks and inefficient gas handling. Our CO₂-based inerting concept is designed to provide:
- Controlled oxygen displacement
- Reduced explosion risk during commissioning
- Minimized methane losses
- Improved operational safety
- Faster and more controlled transition to operation
The system is engineered specifically for:
- Newly built biogas reactor tanks
- Process vessels and storage volumes
- Infrastructure requiring controlled atmosphere management
By integrating compression expertise with CO₂ handling engineering, we deliver a safe, technically robust and environmentally optimised inerting process.
This is a proprietary Regaco concept developed for operators who prioritise safety, control and lifecycle performance.
CCS CO₂ Loading & Off-Loading Systems
CCS CO₂ Loading & Off-Loading Systems
Specialised engineering where CO₂ is used as a process medium or infrastructure component.
Regaco designs engineered systems for:
- CO₂ loading and off-loading terminals
- CCS infrastructure interfaces
- Cryogenic CO₂ transfer installations
- Industrial CO₂ handling systems
We combine process understanding with practical infrastructure engineering — ensuring safe and compliant CO₂ transfer across industrial and energy applications.
