Underground CO2 Storage

UNDERGROUND CO2 STORAGE
(CCS / CCUS)

Carbon Capture, Storage (CCS) and Utilisation (CCUS) are important emission reduction technologies and can help to scale up the hydrogen economy (Blue & Green Hydrogen).

Energy storage facility / © Steve Haider, RAG Austria AG

CCS/CCUS technologies involve the CO2 storage deep underground in geological formations, i.e. aquifers and depleted hydrocarbon reservoirs.

Depleted gas reservoirs represent a great opportunity for underground CO2 storage as they provide significant storage capacity and infrastructure in place.

The European Union has defined the criteria for the characterisation and assessment of the potential CO2 storage complex and surrounding area:

Step 1:

Data collection

Step 2:

Building the three-dimensional static geological earth model

Step 3:

Characterisation of the storage dynamic behaviour, sensitivity characterisation, risk assessment

We are here to support you to meet these criteria:

Our extensive reservoir, well engineering and surface facilities expertise, combined with our experience from developing many gas storage operations, makes us the preferred partner for operators planning underground CO2 storage facilities.

We have adopted a robust workflow starting from identifying CCS opportunities to maturing these to underground CO2 storage projects.

Underground Hydrogen Storage

UNDERGROUND HYDROGEN
STORAGE

Hydrogen will play a key role in a clean, secure and affordable energy future.

Green Hydrogen, produced by electrolysis of water and powered from renewables, is the long-term and low/zero-carbon way to produce hydrogen.

Blue Hydrogen, produced from fossil fuels and combined with underground CO2 storage (CCUS, CCS), will help to scale up the hydrogen economy and bridge the gap between Green Hydrogen and those methods currently dominating hydrogen generation.

Hydrogen storage is an important cornerstone for smooth operations of a hydrogen economy.

Underground (geological) storage in depleted gas and oil reservoirs, aquifers and salt caverns appears to be the best option for large-scale and long-term storage while securing a continuous and well-defined supply stream.

Benefit from our experience. Starting from our initial assessment of reservoir and facilities, we deepen your knowledge base through laboratory experiments, special studies and numerical modelling.

Our extensive reservoir, well engineering and surface facilities expertise combined with our experience from developing many gas storage operations, makes us the preferred partner for operators planning hydrogen storage facilities.
