ADNOC has begun work on the world’s first fully sequestered carbon dioxide (CO2) injection well in a carbonate saline aquifer. The project is expected to begin injecting CO2 in the second quarter of 2023.

Yaser Saeed Almazrouei, ADNOC Upstream Executive Director, said carbon capture and storage will play an important role in reducing emissions and achieving global climate goals.

“At Al Reyadah, ADNOC deployed the region’s first carbon capture project at scale and we are taking another tangible step to deliver on our $15 billion decarbonisation action plan with the world’s first fully sequestered CO2 injection well.

“We will continue working to make today’s energy cleaner while investing in the clean energies and technologies of tomorrow to future-proof our business. In doing so, we will enable a lower-carbon future and remain a reliable and responsible energy provider to customers and markets around the world.”

Once operational, the project will initially fully sequester a minimum of 18,000 tonnes per annum of CO2 captured from Fertiglobe’s UAE operations for injection in Abu Dhabi’s onshore carbonate aquifers, supporting ADNOC’s ongoing efforts to capture and store CO2 from its operations.

The CO2 injection well project builds on ADNOC’s carbon capture facility at Al Reyadah, which has the capacity to capture up to 800,000 tonnes of CO2 per year. The well location for CO2 injection as well as targeted geological formations were identified using the results of ADNOC’s extensive 3D seismic survey and the company’s state-of-the-art subsurface modelling capacity.

The project will contribute to the production of lower-carbon ammonia, an effective and cost competitive hydrogen carrier that can be scaled up quickly and has lower-carbon intensity than other fuels. The project will also be monitored and assessed, using advanced technology at ADNOC’s Thamama Digital Centre of Excellence, to ensure the highest levels of environmental safety as the company expands its carbon capture activities to capture five million tonnes per annum by 2030.

The project is the latest in a series of decarbonisation initiatives, including an agreement for ADNOC to acquire 100 per cent of its grid power from the Emirates Water and Electricity Company’s (EWEC) nuclear and solar sources, making the company the first major oil and gas company to decarbonise its power at scale though an agreement of this kind. Additionally, ADNOC recently reached financial close on a $3.8 billion deal to build a MENA first-of-its-kind sub-sea transmission network, connecting ADNOC’s offshore operations to TAQA’s clean onshore power network which once complete, could reduce offshore carbon intensity by up to 50 per cent.
