Why Reverse Compression Is Critical
The Gas Flow Paradigm Is Changing
Historically, gas infrastructure was designed for unidirectional flow:
Transmission → Distribution → End User
With rapid growth in biomethane injection at DSO level, this model is fundamentally changing.
Surplus biomethane volumes increasingly require reintegration into high-pressure transmission networks.
Natural reverse flow is not possible due to pressure differentials.
Reverse compression solves this structural imbalance.
Reverse Compression Enables Grid Reintegration
• Controlled DSO-to-TSO gas transfer
• Pressure balancing across grid levels
• Reduced curtailment of renewable methane
• Optimised utilisation of transmission capacity
Reverse compression is becoming a structural requirement for modern European gas infrastructure.
Engineering Experience for Transmission and Distribution Operators
Regaco has extensive experience delivering engineered compression and grid reintegration systems within regulated gas infrastructure environments across Northern and Western Europe.
We have supplied systems and engineering solutions for:
ENERGINET (Denmark)
EVIDA (Denmark)
FLUXYS BELGIUM (Belgium)
Our solutions support both transmission (TSO) and distribution (DSO) operators where system reliability, regulatory compliance and operational robustness are critical.
Engineered for Regulated Infrastructure
Our reverse compression systems are designed specifically for high-consequence infrastructure applications where failure is not an option.
We design for:
• Near-zero methane emissions through gas-tight crankcase solutions
• High availability and redundancy where required
• Long lifecycle performance under continuous operation
• Integration into live transmission and distribution systems
• Optimised total cost of ownership (TCO)
Reverse compression is critical infrastructure. It must perform consistently, predictably and reliably over decades.
Experience in Transmission & Distribution Environments
All systems are engineered with a lifecycle perspective.
Designed for Long-Term Performance
We focus on:
• Energy efficiency
• Reduced methane emissions
• Low maintenance frequency
• High operational uptime
• Documented reliability
Grid Challenges We Solve
• DSO biomethane overproduction
• Pressure imbalance between grid levels
• Curtailment of renewable methane
• Underutilised transmission capacity
• Stranded gas volumes
Reverse compression systems are critical infrastructure assets. They must perform — not just function.
