Abu Dhabi CCS (Phase 1 being Emirates Steel Industries)
Abu Dhabi CCS was conceived and is managed by Al Reyadah: Abu Dhabi Carbon Capture Company, a Joint Venture 51 per cent owned by the Abu Dhabi National Oil Company (ADNOC) and 49 per cent owned by Masdar (Abu Dhabi Future Energy Company). The current 'project' is the first in a planned series of CCUS developments in the emirate of Abu Dhabi. The source of CO2 for this development is an off stream from the Emirates Steel Industries (ESI) Factory in Mussafah, UAE.
Capture: The ADNOC/Masdar Joint Venture is sourcing CO2 from ESI as a by-product of their direct reduced iron-making process. Al Reyadah is responsible for the construction and operation of the Project’s CO2 dehydration and compression facility located adjacent to the ESI factory.

STORAGE FORMATION AND DEPTH: Abu Dhabi complex carbonate
TRANSPORTATION TYPE: Onshore pipeline
TRANSPORTATION DISTANCE TO STORAGE SITE (LENGTH OF PIPELINE): 43 kilometres / 27 miles
Abu Dhabi CCS involves the capture of CO2 from the Emirates Steel Factory in Abu Dhabi and its transportation to the ADNOC reservoirs for the purpose of enhanced oil recovery (EOR).
The development was conceived and is managed by Al Reyadah: Abu Dhabi Carbon Capture Company, a Joint Venture between ADNOC, the UAE’s state-owned oil company, and Masdar, a wholly-owned subsidiary of the Abu Dhabi Government-owned Mubadala Development Company. The Masdar initiative was launched in 2006 to establish Abu Dhabi’s clean energy industry and this CCS Project, sourcing CO2 from ESI, is the first of a number of planned core components that would form an Abu Dhabi wide CCUS network.
The source of CO2 for this development, ESI, was established in 1998 and in 2001 it commenced manufacturing a range of industrial-purpose steel products. A two-stage expansion of the plant was completed in 2012, increasing its Direct Reduced Iron (DRI) capacity to 3.2 Mtpa. The DRI process employed at ESI produces a pure stream of CO2 (greater than 98 per cent) which is currently vented to the atmosphere. The CO2 is captured using an amine based contactor / regenerator system. The CO2 capture rate from the DRI process is greater than 90 per cent.
The Abu Dhabi CCS scope includes operation of a green field CO2 Compression Facility (CCF) including dehydration, located within ESNAAD (an ADNOC Group company), adjacent to the ESI factory in Mussafah, Abu Dhabi. CO2 is transferred at low pressure to the CCF where it is dehydrated (to less than 20lb/MMscf), compressed to 235barg (via an Integrally Geared LP Compression followed by Reciprocating HP Compression), metered and exported to the CO2 Pipeline. The CCF design capacity is 0.8 million tonnes per annum (Mtpa).
The CO2 is transported 43 kilometres / 27 miles through an eight inch pipeline for injection into ADNOC reservoirs for EOR purposes. Development planning and operations for these fields rests with ADNOC operating companies.
In 2009-2011 Masdar and ADCO (an ADNOC group OPCO) undertook a pilot project involving the injection of approximately 60 tonnes of CO2 per day into the ADNOC Rumaitha oilfield. The pilot project included three wells – a CO2 injection well, an observation well and an oil producing well. The pilot provided information on the amounts of CO2 required for injection and the potential volume of oil recoverable.
In November 2013 ADNOC and Masdar formalised the joint venture agreement and awarded the Dodsal Engineering and Construction Group with a Dh450 million (US$122.5 million) EPC contract to build the CO2 dehydration and compression facility and the 43 kilometre / 27 mile pipeline to Rumaitha.
March 2007: Masdar announces a strategic initiative to develop a national CCS network that links a number of industrial capture facilities to oilfields operated by ADNOC for the purpose of EOR.
February 2008: Masdar completes a feasibility study for its national CCS network initiative. The study selects the Emirates Steel Factory as one of four sites that will form the basis of the first phase of their CCS initiative.
April 2010: A front-end engineering design (FEED) study is completed for the proposed ESI CO2 capture facilities and pipeline.
November 2011: Masdar and ADCO (an ADNOC OPCO) successfully complete a pilot CO2 injection project at the ADNOC Rumaitha field.
January 2012: ADNOC and MASDAR announce an agreement allowing the Abu Dhabi CCS facility based at the Emirates Steel Factory to proceed to tender.
November 2013: The ADNOC and Masdar Joint Venture awards the Dodsal Engineering and Construction Group with a Dh450 million (US$122.5 million) EPC contract to build the CO2 compression and dehydration facilities at the ESNAAD site in Mussafah and 43 kilometre pipeline to ADNOC reservoirs.
July 2014: Construction of the Carbon Capture Facility (CCF) and pipeline commences on-site in ESNAAD adjacent to the ESI facilities in Mussafah, Abu Dhabi.
November 2014: ADNOC and Masdar formally unveil Al Reyadah Abu Dhabi Carbon Capture Company, the Middle East’s first specialist company focused on exploring and developing commercial-scale projects for carbon capture, usage and sequestration (CCUS).
November 2016: The Project is officially launched.
