Aramco eyes carbon capture investment decision

28 March 2023

 

Saudi Aramco is expected to reach a financial investment decision by year-end on the first two phases of its project to develop a carbon capture and storage infrastructure in Saudi Arabia that will tap carbon dioxide (CO2) discharge from its gas processing plants.

MEED understands the first two phases will require a capital expenditure of between $1.5bn and $2bn.

As previously reported, Aramco has brought on board US oil field services provider SLB (formerly Schlumberger) and Germany-headquartered Linde, the world’s largest industrial gas producer, as partners for the initial phase of the project.

The second-phase partners are US-headquartered Air Products and oil field services provider Baker Hughes.

Aramco is expected to issue the main tender for the Accelerated Carbon Capture & Sequestration (ACCS) project to contractors in April, as MEED reported.

The firm issued a solicitation of interest (SoI) document for the project in January.

The ACCS project aims to capture carbon dioxide from Aramco’s northern gas plants of Wasit, Fadhili and Khursaniyah, as well as from the operations of its subsidiary Saudi Basic Industries Corporation (Sabic) and Saudi industrial gases provider Air Products Qudra.

UK-headquartered Wood Group has performed the planned project’s front-end engineering and design work.

It is understood Japan’s Mizuho is the client’s financial adviser for the transaction.

The project’s construction period is expected to take three years, with commercial operation scheduled for 2027.

According to an industry source, the project will have nine phases, with total capacity expected to reach 44 million tonnes a year (t/y).

ACCS project scope

The ACCS facility will capture streams from the acid gas enrichment units of the Wasit, Fadhili and Khursaniyah plants. The CO2 will be compressed, dried and fed into the collection pipeline system.

The network will also absorb additional CO2 volumes from Sabic and Air Products Qudra after the initial compression and drying of the CO2 discharge at their respective facilities.

The combined gaseous CO2 stream will then be compressed at the centralised compression facility located at Fadhili into dense phase CO2 and sent into the main pipeline for sequestration.

The main pipeline network will transport the CO2 about 240 kilometres away for injection into the Jaham-Duhul-Maqlah saline aquifer.

The ACCS project scope finishes at the injection well control skids. Injection wells and other associated units are outside the scope of the ACCS project, Aramco said in the SoI document.

The ACCS project’s initial phase is expected to have a capacity of about 9 million t/y, with the collection pipeline system designed to support the future expansion of the scheme.

Aramco held an early engagement meeting on 20 February with interested contractors to discuss the project. Contractors that attended the conference include:

  • GS Engineering & Construction (South Korea)
  • Hyundai Engineering (South Korea)
  • JGC Corporation (Japan)
  • Larsen & Toubro Energy Hydrocarbon (India)
  • Saipem (Italy)
  • Tecnicas Reunidas (Saipem)
  • Tecnimont (Italy)
Aramco sustainability measures

Saudi Aramco is making its core operations more environmentally friendly to meet its target of attaining net-zero carbon emissions by 2050 and in line with Saudi Arabia’s net-zero emissions by 2060 target.

Aramco does not face the same intense pressure from climate activists and investors to slash carbon and greenhouse gas (GHG) emissions and tackle climate change as some of its international counterparts.

As the main engine of Saudi Arabia’s economy, Aramco is crucial in helping the kingdom achieve its Cop26 environmental commitments.

  • Dubai plans EPC tender for Warsan sewage treatment plant

    25 February 2026

     

    Register for MEED’s 14-day trial access 

    Dubai Municipality is preparing to tender the main construction package for the Warsan sewage treatment plant (STP) by the end of the year, according to sources close to the project.

    The scheme is linked to the deep sewerage tunnels infrastructure programme being implemented by the municipality’s sewerage and recycled water projects department.

    As MEED understands, the Warsan STP had previously been expected to be procured as a public-private partnership (PPP) scheme.

    However, sources confirmed that the main construction package will now be procured as an engineering, procurement and construction (EPC) contract.

    The project involves the construction of a sewage treatment plant with a capacity of about 175,000 cubic metres a day (cm/d), including treatment units, sludge handling systems and associated infrastructure.

    The plant, estimated to cost about $326m, will be developed at the existing Warsan complex, where the municipality is also progressing separate expansion and rehabilitation packages.

    These include Warsan STP Phase 1 (DS-355/1), which involves sewerage and stormwater network upgrades, and Stage 2 of the Al-Warsan sewage treatment plant (DS-203/2), comprising new treatment units

    Kuwait-headquartered Mohammed Abdulmohsin Al-Kharafi & Sons is the main EPC contractor for both projects.

    Separately, the municipality is also progressing the expansion and upgrade of the first and second phases of the Jebel Ali STP.

    The upgraded facility will be capable of treating an additional sewage flow of 100,000 cm/d.

    Earlier this month, contractors were invited to prequalify for the contract.

    The bid submission deadline is 2 April.

  • Algeria gives bidders more time for 1.2GW plant

    25 February 2026

    Algeria’s state-owned electricity and gas utility Sonelgaz has extended the bid submission deadline for a contract to build a 1,200MW combined-cycle gas-fired power plant in Adrar.

    The project is being procured through Sonelgaz’s power generation subsidiary, Societe Algerienne de l’Electricite et du Gaz – Production de l’Electricite (SPE).

    The new bid submission deadline is 29 April. The main contract was first tendered in April last year, and the deadline has been extended several times since.

    The latest deadline was 26 February.

    The tender is open to local and international companies with experience in delivering large-scale power generation projects and with sufficient technical and financial capacity.

    Algeria’s wider power sector has experienced periods of limited contract activity in recent years. Between 2018 and 2022, virtually no new solar or wind farm contracts were awarded, according to available data from the regional projects tracker MEED Projects.

    In 2023, Sonelgaz Energie Renouvelables, a subsidiary of Algeria’s state-owned utility, awarded 14 of the 15 solar photovoltaic (PV) packages it tendered that year.

    At the time, MEED reported that the 15 packages had a total combined capacity of 2,000MW, requiring at least AD172bn ($1.2bn) of investment.

    However, publicly available data suggests that progress has been slow with several schemes yet to reach full construction or commercial stages.

    Gas-fired combined-cycle plants continue to account for the majority of Algeria’s electricity generation capacity. Data from MEED Projects indicates that more than 5,000MW of oil- and gas-fired power capacity is currently under construction.

    Despite this, new contract awards in 2025 came from three solar schemes.

    This included the construction of a 154MW solar PV plant in Bechar, for which China Power was appointed main contractor in August.

  • Riyadh tenders Line 7 metro project management deal

    25 February 2026

     

    Register for MEED’s 14-day trial access 

    The Royal Commission for Riyadh City (RCRC) has issued a tender inviting firms to bid for a contract for project management consultancy services for the construction of Riyadh Metro Line 7.

    MEED understands that RCRC has allowed firms until March to submit their proposals.

    The latest development follows contractors submitting bids on 31 January for a contract to design and build the project.

    The project involves constructing a metro line linking the Qiddiya entertainment city development, King Abdullah International Gardens, King Salman Park, Misk City and Diriyah Gate. The total length of the line will be about 65 kilometres (km), of which 47km will be underground and 19km will be elevated.

    The line will have 19 stations, 14 of which will be built underground and five above ground.

    Riyadh Metro’s first phase features six lines with 84 stations. The RCRC completed the phased roll-out of the Riyadh Metro network when it started operating the Orange Line in January this year.

    Construction has also begun on the next phase of Riyadh Metro, the extension of Line 2.

    In July last year, MEED exclusively reported that RCRC had awarded an estimated $800m-$900m contract for the project.

    The contract was awarded to the Arriyadh New Mobility Consortium, led by Italy’s Webuild. 

    The group also includes India’s Larsen & Toubro, Saudi Arabia’s Nesma & Partners and France’s Alstom.

    Line 3, also known as the Orange Line, stretches from east to west, from Jeddah Road to the Second Eastern Ring Road, covering a total distance of 41km. 

    The line spans 8.4km, of which 1.3km is elevated and 7.1km is underground. It includes five stations – two elevated and three underground.

    It will run from the current terminus of Line 2 at King Saud University (KSU) and continue to new stations at KSU Medical City, KSU West, Diriyah East and Diriyah Central – where it will interchange with the planned Line 7 – before terminating at Diriyah South.

  • Six companies prequalify for Algeria gas contract

    25 February 2026

    Register for MEED’s 14-day trial access 

    Six companies have prequalified for a contract that is part of a project to connect the liquefied natural gas (LNG) storage and loading lines of the gas complexes known as GL1Z and GL2Z, according to a statement issued by Algeria’s state-owned oil and gas company Sonatrach.

    The two complexes are part of Sonatrach’s Arzew LNG hub.

    The scope of work for the contract is focused on the execution of the basic engineering study for the project.

    The six companies that have prequalified for the project are:

    • JGC (Japan)
    • McDermott (US)
    • Synergy Engineering (Indonesia)
    • ExidaSP (UAE)
    • EPPM (Tunisia)
    • Enreco (Italy)

    In its statement, Sonatrach said: “Following the review of applications, the companies … have been prequalified and will be invited to participate and submit bids in the selective consultation.”

    The Arzew LNG hub is Algeria’s main LNG export centre, located near the port town of Arzew, about 40 kilometres east of Oran on the Mediterranean coast.

    Sonatrach is currently implementing several projects to upgrade facilities within the hub.

    In October last year, MEED revealed that the gas train known as T-300 had been brought back online at the site.

    The train was brought back online after a new main cryogenic heat exchanger (MCHE) was commissioned.

    The upgrade was part of a broader contract with US-based Honeywell to replace four MCHEs at GL1Z.

    The contract was originally signed with Air Products, and Honeywell acquired the contract when it bought Air Products’ LNG process technology and equipment business in September 2024.
