Taziz fulfils Abu Dhabi’s chemical ambitions at pace

8 October 2025

 

Taziz was created to extract more commercial value from Abu Dhabi’s hydrocarbon production by directing a portion of it to local third-party investors to use as feedstock to produce high-value chemicals – some of which had never been manufactured in the UAE before.

Four years since its establishment, the Abu Dhabi National Oil Company (Adnoc Group) subsidiary has performed commendably in fulfilling its core mandate: attracting specialty chemical players to the country.

Taziz – a 60:40 joint venture of Adnoc Group and Abu Dhabi’s industrial holding company ADQ – is in the execution phase of six out of the seven projects it announced under the first phase of its sprawling chemical derivatives complex in Ruwais Industrial City.

The latest of the Taziz Industrial Chemicals Zone projects to make progress is Project Salt – a cluster of three plants that will produce ethylene dichloride (EDC), chlor-alkali and polyvinyl chloride (PVC).

The planned EDC plant will use chlorine from the associated chlor-alkali plant as its main feedstock and will have a production capacity of up to 1.2 million tonnes a year (t/y).

Part of the EDC output will, in turn, be used as feedstock by the PVC plant, which is planned to have a production capacity of 350,000 t/y. Surplus quantities of EDC and caustic soda from the chlor-alkali plant are intended to be exported.

A consortium of Chinese contractors – China National Chemical Engineering Company, China Chengda Engineering Company and China Tianchen Engineering Corporation – is the frontrunner to win the main contract for Project Salt, according to sources.

South Korean contractor Samsung E&A is understood to have been the only other bidder for Project Salt.

Taziz first announced the EDC, chlor-alkali and PVC plants in December 2021. India’s Reliance Industries was named as the main investor in the chemical plants at the time. Reliance is understood to have withdrawn from Project Salt and has been replaced by France-based Kem One.

Taziz Industrial Chemicals Zone

In addition to the three chemical plants planned under Project Salt, Taziz awarded Samsung E&A the main engineering, procurement and construction (EPC) contract in February to build the UAE’s first methanol plant in the Taziz Industrial Chemicals Zone.

The value of the EPC contract is $1.7bn, with a construction duration of 44 months.

The nameplate production capacity of the planned methanol complex is 5,000 metric tonnes a day, or 1.8 million metric t/y. Switzerland-based energy and chemicals company Proman is a joint investor in the project.

Separately, a joint venture of UAE-based Fertiglobe, South Korea’s GS Energy Corporation and Japanese investment firm Mitsui & Company has invested in a “world-scale” blue ammonia production facility in the Ruwais petrochemicals derivatives complex.

The Fertiglobe/GS Energy/Mitsui joint venture awarded Italian contractor Tecnimont the EPC contract for the project in May 2024. Construction on the facility started in June last year.

Fertiglobe has also planned an expansion phase of the blue hydrogen and blue ammonia production complex, to be developed under the second phase of the Taziz Industrial Chemicals Zone. Known as Project Rabdan, the new complex will use natural gas supplied by Adnoc – Fertiglobe’s parent company and majority shareholder – to produce up to 1 million t/y of low-carbon liquid ammonia, also known as blue ammonia.

The Rabdan facility will also have the capacity to produce 192,000 t/y of blue hydrogen and 892,000 t/y of nitrogen for supply to a local offtaker. In addition to the main blue ammonia production plant, the planned complex will feature units for hydrogen production and synthesis gas purification, as well as pipelines for the transport of feedstock gas, hydrogen and nitrogen. 

The Rabdan facility will have its own storage, export, utilities and offsite units, and will also tap into those from the wider Taziz ecosystem. A carbon capture and storage (CCS) system within the Rabdan complex will capture, compress and transport carbon dioxide emissions from its operations to a larger Adnoc CCS hub in Ruwais.

Adnoc/Fertiglobe had initiated a feed-to-EPC competition to deliver the Rabdan project in the first quarter of the year, with contractors submitting proposals for the contest in March. The project operators had even shortlisted India’s Larsen & Toubro Energy Hydrocarbon, Germany-based Linde and French contractor Technip Energies to participate in the feed-to-EPC competition for the project.

However, the prices submitted by the bidders for feed work were above Adnoc/Fertiglobe’s budget, leading to a stalemate. A final investment decision on Project Rabdan is now expected in 2026.

Adnoc Group downstream projects

Other downstream subsidiaries of Adnoc Group, particularly Adnoc Gas, continue to make progress with vital projects. Adnoc Gas recently received technical bids from contractors for EPC works on a major project to add a new gas processing train at its Habshan complex in Abu Dhabi.

Adnoc Gas, the natural gas processing business of Adnoc Group, processes about 10 billion standard cubic feet a day (cf/d) of gas across several sites, including its Asab, Bab, Bu Hasa and Habshan facilities, as well as a natural gas liquids (NGL) fractionation plant at Ruwais.

The Habshan complex is one of the biggest gas processing facilities in the UAE, and in the Middle East and North Africa region. Its output capacity is 6.1 billion cf/d. The complex comprises five trains and 14 processing units that receive gas feedstock from onshore and offshore fields in Abu Dhabi.

With Adnoc Group pressing ahead with its P5 programme to raise oil production potential to 5 million barrels a day by 2027, high volumes of associated gas are set to enter the grid.

The new train at the Habshan complex, which Adnoc Gas expects to commission in 2029, will play a key role in handling these additional gas volumes.

Meanwhile, contractors have submitted technical proposals to Adnoc Gas for feed work as part of a design-update competition for a project to install a fifth natural gas liquids (NGL) fractionation train at its Ruwais gas processing facility.

The fifth NGL fractionation train will have an output capacity of 22,000 tonnes a day (t/d), or about 8 million t/y. It will also include NGL fractionation facilities, downstream treatment units, sulphur recovery units, product storage, loading facilities and associated utilities. The scope also covers flares, interconnection pipelines with existing facilities, two propane liquefied petroleum gas storage tanks and one paraffinic naphtha storage tank.

  • Saudi Arabia’s private sector picks up the baton

    2 March 2026

     

    Ten years of ambitious construction project launches ended on 25 January 2026, when the Olympic Council of Asia and the Saudi Olympic & Paralympic Committee released a joint statement saying that they had agreed to indefinitely postpone the 2029 Asian Winter Games. In early February, it was announced that Almaty in Kazakhstan will host the event.

    The Trojena mountain resort at Neom in northwest Saudi Arabia was selected in 2022 as the venue for the games, and despite significant construction work on the project, rumours had been circulating throughout most of 2025 that the greenfield venue would not be ready by the 2029 deadline.

    Project reprioritisation

    Trojena is not the only project in the kingdom that has been subject to scrutiny. There have been reports of other projects, including The Line and the Mukaab, either being scaled back, delayed or put on hold as Riyadh reassesses its priorities. This has created an air of uncertainty over Saudi Arabia’s upcoming project pipeline.

    Speaking at the Private Sector Forum (PSF), held in Riyadh in early February, Khalid Al-Falih, then Saudi Arabia’s investment minister and now minister of state, said that much has changed since Vision 2030 was launched in 2016, and that this has naturally warranted a reprioritisation. 

    Al-Falih, who also sits on the Public Investment Fund’s (PIF’s) board of directors, said that with Saudi Arabia having been chosen to host football’s Fifa World Cup in 2034 and Expo 2030 Riyadh – and as the global economy is evolving rapidly with the rise of artificial intelligence (AI) – some projects such as The Line at Neom have slowed down. However, other projects related to the World Cup, Expo 2030, technology and AI have accelerated. 

    PIF strategy

    In his speech at the PSF, Yasir Al-Rumayyan, governor of the PIF, also alluded to changing priorities and said that this is a pivotal moment for Saudi Arabia’s economy. 

    Launched in 2016, Saudi Arabia’s Vision 2030 is described as “a transformative and ambitious blueprint to unlock the potential of its people and create a diversified, innovative and world-leading nation”. 

    The agency charged with delivering many of the objectives outlined in the strategy is the PIF. Established in 1971, it was moved from the Finance Ministry in 2015 to the Council of Economic & Development Affairs, where it was given a more active mandate. It then grew from a staff of about 50 in 2015 to almost 3,000 in 2024, according to the most recently published annual report.

    Over the past 10 years, the PIF has helped drive the development of key sectors with direct capital spending on projects. The Red Sea Project and the Qiddiya entertainment city development aim to position the kingdom as a leisure tourism destination, while Roshn’s portfolio of residential communities has helped transform the housing market.

    The PIF had $913bn of assets under management in 2024. Its activities are too varied to list, but they include developing the kingdom’s five official gigaprojects; holding investments in Saudi companies including Saudi Aramco and Maaden; owning stakes in electric vehicle manufacturers Lucid and Ceer, and gaming companies Nintendo and Electronic Arts; and owning UK Premier League football team Newcastle United.

    In 2026, the role of the PIF is changing. Speaking at the PSF, Al-Rumayyan extended an invitation to the private sector to play a bigger role in achieving the kingdom’s economic ambitions. 

    “Today, in line with the objectives of the third phase of Saudi Vision 2030 and the PIF’s strategy for the coming five years, we are moving from building sectors to integrating ecosystems, and from launching opportunities to accelerating growth – through an open invitation to the private sector to invest and partner in shaping a diversified and resilient economy,” he said.  

    Having raised the bar, PIF officials say that sectors such as tourism and real estate are now ready for the private sector to take over. They describe sectors reaching what they call ‘escape velocity’, which is the point where a sufficient level of maturity has been reached for the private sector to come in and take the lead.

    [In 2026, the PIF is] moving from building sectors to integrating ecosystems, and from launching opportunities to accelerating growth

    Financial considerations

    The decision to pass the baton to the private sector comes at a time when Saudi Arabia’s ability to finance all its project commitments directly has been questioned amid lower-than-desired oil prices. 

    Reflecting the constrained backdrop, the Ministry of Finance’s final budget statement for 2026 projects a deficit of SR165bn ($44bn), equivalent to about 3.3% of GDP. 

    The private sector has a tough act to follow. While the PIF has embarked on some of the world’s most ambitious projects in recent years, it has also introduced international standards that it hopes will lead to ways of doing business in Saudi Arabia that are more in tune with international best practices. 

    “The fund will continue to enable ecosystems and lay the foundations for growth. At the same time, the next phase requires a higher level of readiness and ambition from the private sector, alongside the ability to scale and innovate – a phase in which the role of the private sector evolves from execution to contributing to economic building and value creation,” Al-Rumayyan said. 

    Whether the private sector is ready to take over is the critical question in 2026. 

    According to PIF subsidiary development companies (devcos) that engage with private sector investors, the tide is turning. They say that five years ago, the appetite to invest was limited and devcos had to step in and deliver a greater proportion of project masterplans. As these investors complete their first projects, however, confidence is building.

     

    Deals signed

    This growing appetite could be seen at the PSF, where agreements were signed by private sector investors and devcos. 

    Rua Al-Madinah, which is responsible for Medina’s tourism and cultural development, signed a memorandum of understanding (MoU) with Indonesian sovereign wealth fund, Danantara Indonesia. It covers identifying and assessing investment opportunities in the Rua Al-Madinah and Dar Al-Hijrah projects.

    King Salman International Airport Development Company signed several MoUs with local firms to develop mixed-use projects within its airport masterplan. The agreements were signed with Sumou Holding, Mohammed Al-Habib Investment, Kinan, Ajdan, Retal, Urjuan and Osus and comprise residential, commercial, retail, hospitality, entertainment and other related projects.

    Roshn Group also signed an agreement with Kuwait’s Agility Logistics Parks to establish a joint venture that will develop a Grade A logistics hub.

    In mid-February, two further deals were signed. PIF-backed Smart Accommodation for Residential Complexes Company (Sarcc) signed an agreement with Dammam-based Tamimi Global Company to develop a 4,000-bed worker accommodation project in North Riyadh. The development is expected to cost over SR1.5bn ($400m).

    Sarcc also signed a separate agreement with Riyadh-based Mawref Company to develop another North Riyadh worker accommodation project. This deal involves building a 12,000-bed facility with a development cost of over SR669m ($178m). 

    The first phases of both projects are expected to be completed in 2029.

    While momentum continues to build and deals are signed, some private sector players remain to be convinced. In the kingdom’s real estate sector, for example, recent amendments to legislation, which include a white land tax and a rent freeze, have created a level of uncertainty that some potential investors say makes it difficult to sign off on investment commitments. 

    Much will depend on the success of the deals already signed. If these agreements result in positive outcomes, then the fear of missing out will kick in and other private sector players will be keen to invest. 

    The risk is that, should deals turn sour and fail to produce the expected results, then attracting future investments from the private sector will be challenging.

  • Algiers moves on new railway project

    2 March 2026

     

    Algeria’s state railway company Agence Nationale d’Etudes et de Suivi de la Realisation des Investissements Ferroviaires (Anesrif) has formally started the procurement process for its multibillion-dollar Laghouat-Ghardaia-El-Meniaa railway project.

    International and local firms have been given until 8 March to submit expressions of interest for the overall client’s engineer role on the 495-kilometre-long railway development.

    Consultancies have also been given until 12 March for two separate contracts covering the project supervision and control of the first 265km-long element between Laghouat and Ghardaia, and the 230km-long line between Ghardaia and El-Meniaa.

    This Laghouat-Ghardaia section, which is estimated to cost about $1.4bn, will comprise 21 viaducts, one tunnel, 55 pipe crossings and five stations.

    The 230km-long Ghardaia to El-Meniaa second section will start at Metlili station and extend south to El-Meniaa. It will comprise six viaducts, 35 railway structures and three stations, and have an estimated total construction cost of about $1.2bn.

    The speed of passenger trains on the railway will be 220 kilometres an hour (km/h) and 100km/h for freight trains.

    The solicitations of interest for the construction of the two sections were originally scheduled for February, but to date have not been released.

  • Saudi developer Acwa names new CEO

    2 March 2026

    Saudi Arabia’s Acwa has appointed Samir J Serhan as CEO, effective 1 March 2026.

    Serhan joined Acwa, formerly Acwa Power, last year as president for Saudi Arabia and the Middle East. He previously served as chief operating officer of US-based Air Products, where he had global responsibility for operational business and project execution across the Americas, Asia, Europe, Africa, the Middle East and India.

    Earlier in his career, he was president of hydrogen at Praxair and held senior leadership roles at Linde Group in the US and Germany, including managing director of Linde Engineering.

    Outgoing CEO Marco Arcelli will remain as an adviser to the chairman to ensure continuity.

    Arcelli said: “Over the past three years, Acwa’s portfolio has doubled in size, and we are on track to double it again by 2030, scaling both our footprint and our impact. Acwa now produces around 25% of the world’s desalinated seawater.”

    He added: “We have expanded into new markets, including Azerbaijan, China, Kuwait and Senegal, while advancing energy export opportunities from Saudi Arabia.”

    Acwa recently extended its lead at the top of the GCC Water Developer Ranking, adding 265,925 cubic metres a day (cm/d) in net capacity from new contract awards in 2025.

    The biggest of these involves a contract to develop the Ras Mohaisen independent water plant, awarded by the Saudi Arabian state offtaker Sharakat, formerly Saudi Water Partnership Company.

    The project is located on the kingdom’s Red Sea coast and will have the capacity to treat 300,000 cm/d of seawater using reverse osmosis technology.

    MEED reported last September that Acwa’s net power generation capacity in the GCC was 28.1GW, with the company holding more equity than the rest of the region’s top 10 private power developers combined.

  • Amazon data centre hit highlights sector vulnerabilities

    2 March 2026

     

    Amid ongoing Iranian missile and drone attacks on GCC states, US cloud provider Amazon Web Services (AWS) has reported service outages following separate incidents at two of its UAE data centres.

    “At around 4.30AM PST [16.30 UAE time on 1 March], one of our Availability Zones (mec1-az2) was impacted by objects that struck the data centre, creating sparks and fire,” AWS said in an operational update on 1 March.

    At 10.46 UAE time on 2 March, the company announced a further update, saying that another of its three UAE Availability Zones had gone down.

    “We can confirm that a localised power issue has affected another Availability Zone in the ME-CENTRAL-1 Region (mec1-az3),” it said in the latest update. “Customers are also experiencing increased EC2 APIs and instance launch errors for the remaining zone (mec1-az1). At this point, it is not possible to launch new instances in the region, although existing instances should not be affected in mec1-az1.

    “Other AWS services, such as DynamoDB and S3, are also experiencing significant error rates and latencies. We are actively working to restore power and connectivity, at which time we will begin to work to recover affected resources. As of this time, we expect recovery is multiple hours away.”

    Regional footprint

    The company, part of the US’ giant Amazon group, is one of the world’s largest data centre and cloud operators. It operates three data centres in the UAE – one in Dubai and two in Abu Dhabi – and provides critical IT services to government and private sector operations and systems.

    Its Availability Zones consist of infrastructure in separate geographic locations, spaced far enough apart to significantly reduce the risk of a single event affecting customers’ business continuity, yet near enough to provide low latency for high-availability applications that use multiple zones.

    The targeting of the two data centres – and potentially others if the conflict continues – highlights the strategic importance of these types of facilities. The AWS attacks are believed to be the first time a data centre has been targeted in a conflict and are likely to drive a reconfiguration of future campus designs to account for similar risks.

    Such changes could include increased redundancies – particularly in power provision – enhanced structural resilience, and potentially a reconsideration of the location and clustering of data centre facilities.

    WATCH: Ed James explores the rapidly evolving GCC data centres market

    Historically, data centres in the region were largely smaller enterprise facilities dedicated to storage services for organisations such as banks. Their locations were often confidential and in areas that were difficult to target, making them harder to disrupt.

    However, the emergence of large in-region hyperscale data centres – with IT loads of 200MW or more and larger physical footprints – may necessitate a rethink of how such infrastructure is delivered, not just in the GCC but worldwide.

    According to MEED Projects data, there are believed to be about 185 data centres in the region, each with an estimated capex investment value of more than $10m, of which about 99 are either planned or under construction.

  • Contractor wins Oman water network contract

    2 March 2026

    Egypt’s Hassan Allam Construction has won an engineering, procurement and construction (EPC) contract for a water transmission network project from Al-Jardaa to Mihlaih (Sawt) in Oman’s North Al-Sharqiyah Governorate.

    The contract was awarded by Oman Water & Wastewater Services Company (OWWSC).

    The scope includes 76 kilometres of transmission lines and nearly 600km of distribution networks.

    The project also covers seven high-capacity reservoirs, two pumping stations and seven solar-powered systems.

    Hassan Allam Construction won a separate contract with OWWSC in August 2025 to build and supervise the construction of a large-scale water supply and wastewater system in Al-Amerat, Muscat.

    The Al-Amerat Catchment 10 water supply, sewer system and treated effluent networks project covers the construction of a 64km gravity sewer network.

    Last month, MEED exclusively revealed that China’s Hunan Installation Overseas Engineering had won an EPC contract to build water supply and sewage networks in Muscat. 

    The contract was awarded by state utility Nama Water Services (NWS).
