CCUS explained: all about carbon capture, utilisation and storage

To support you as effectively as possible and offer innovative ways of reducing your facilities’ carbon emissions, we are anticipating regulatory developments* by exploring carbon capture and storage.

We are planning to invest several tens of millions of euros in research and development by 2027 in order to develop CCUS solutions that can be deployed in waste and wastewater treatment facilities.

Capturing CO₂

Capturing CO₂ is the first part of the CCUS process. We analyse and compare various CO₂ capture solutions in order to advise on the technologies best suited to each kind of project. We identify the right partners and integrate the carbon capture process as efficiently as possible into existing facilities.

Utilising CO₂

We are exploring solutions to turn the captured CO₂ into high-value products, thereby creating a circular economy. We assess various innovative ways of recycling CO_2, for instance to help decarbonise transport through the production of alternative low-carbon fuels (eFuels) and to develop other innovative uses (conversion into chemicals, mineralisation, etc.).

Storing CO₂

Once captured, the CO₂ can also be stored safely for the long term. We assess geological storage solutions in which CO₂ is injected into geological reservoirs, where it will remain for a very long period, i.e. stored in depleted gas reservoirs or dissolved in deep confined aquifers.
