Pilot chain (2027+)
≈300 kt/y
Duslo high-purity CO₂ captured, transported and stored via ENGAS Golianovo hub.
CarbonNet Slovakia
CO₂ Pipeline Network Project
Two hubs. One open-access CO₂ backbone.
Start with two industrial anchors, then scale to a multi-client infrastructure platform.
Cement cluster (2033+)
>500 kt/y
Trenčín region cement catchment (Ladce + CEMMAC) enabled via SaveGas hub.
Storage cluster
2 hubs
Golianovo (ENGAS) + Veľké Kostoľany/Špačince (SaveGas) for capacity and redundancy.
Build once, decarbonise many — with predictable permitting.
Open-access pipelines lower €/t for follow-on emitters. The critical path is administrative acceleration (routing, EIA, storage permitting).
Why CCS needs infrastructure — not one-off projects
Shared pipelines and storage hubs reduce risk and accelerate deployment.
The challenge
- Hard-to-abate sectors (fertiliser, cement) face rising ETS exposure.
- Single-plant CCS is slow and expensive when every permit is "first-of-a-kind".
- Linear infrastructure (routes, crossings) drives time and CAPEX.
- Cement capture retrofits often need ~7 years → permitting must be predictable.
The infrastructure answer
- Open-access pipelines + shared storage hubs = lower marginal cost per new shipper.
- One permitting template (Act 258/2011) reused across emitters.
- Phased scale-up: start small, then ramp with modular wells and injection capacities.
- Two hubs add redundancy, capacity and route options in Western Slovakia.
CarbonNet Slovakia is designed as an infrastructure platform: scalable, multi-client, and predictable to permit.
Balanced platform structure (ENGAS + SaveGas)
Two complementary hubs enabling phased scale-up to a multi-client CO₂ backbone.
ENGAS — Golianovo hub
- CCS-ready storage site and first-mover chain for Slovakia
- Pilot full chain: Duslo → Golianovo (pipeline + injection + MRV)
- Backbone planning: pipelines, compression and buffering concepts
- Commercial: long-term transport & storage service agreements (TSA)
SaveGas — Kostoľany & Špačince hub
- Gas production pathway enabling CCS repurposing after depletion
- Shorter branches to cement & power emitters (incl. Trenčín corridor)
- Reuse subsurface work and established pipeline corridors where possible
- Adds redundancy and capacity to the Western Slovakia storage cluster
CarbonNet Slovakia is a working project name (not a legal entity). Applicants / contact entities: ENGAS s.r.o. and SaveGas SR, s. r. o.
Open-access design: other emitters are invited to join.
Interim gas production (depletion) supports energy security
Temporary domestic gas production can finance data gathering and prepare CCS conversion (not subsidy-eligible).
Veľké Kostoľany gas phase (indicative)
≈0.32–0.38 bcm
Extractable gas (planning cases)
≈45–65 mcm/y
Indicative annual output
Duration: ≈5–7 years (order-of-magnitude)
Indicative impact
Slovakia's current domestic gas production is often cited around ≈55 mcm/year. The Veľké Kostoľany phase could temporarily add ≈80% to +120% (order-of-magnitude), while keeping wells CCS-ready.
Policy framing
Include as "depletion phase to prepare CCS conversion". Not eligible for CCS subsidies; supports project bankability and data.
All gas figures are indicative planning ranges; final output depends on reservoir performance and development plan.
Administrative acceleration: what unlocks delivery
Procedural clarity (not financial claims) — aligned with the formal filing to Ministry of Environment SR (MoE).
