Gulf charts pathway to clean steel production

1 August 2024

 

Steel manufacturing accounts for 7%-9% of global carbon dioxide (CO2) emissions and is considered a hard-to-abate industry. With a forecast for strong growth in global steel production in the coming decades, changes need to be implemented to bring steelmaking in line with the UN Paris Climate Agreement goal of limiting global warming to 1.5 degrees Celsius.

The need for the international steel industry to slash CO2 and greenhouse gas emissions dominated the agenda at UN climate change summit Cop28 in Dubai last December, with about 35 companies and six industry associations, including the World Steel Association, endorsing the Industrial Transition Accelerator. The initiative aims to scale implementation and delivery of decarbonisation in the steel, aluminum, cement, transportation and energy sectors.

There are many levers for steel decarbonisation, including the electrification of heat generation, improving energy efficiency and increasing the utilisation of scrap steel. However, to reach net-zero, further steps are needed to address the emissions associated with coal’s role as a reducing agent in ironmaking. Breakthrough technologies that can accomplish this include hydrogen direct reduction to replace coal; carbon capture, utilisation and storage; and electrolysis-based, or green hydrogen-supported, production processes.

The Middle East and North Africa accounts for just 5% of global steel output. Despite this low market share, however, steelmakers in the region – particularly in the Gulf – have committed billions of dollars to investments in steel projects that could implement most proven clean technologies.

To reach net-zero, further steps are needed to address the emissions associated with coal’s role as a reducing agent in ironmaking

Saudi clean steel projects

Saudi Aramco, the kingdom’s sovereign wealth institution the Public Investment Fund (PIF) and Chinese steel manufacturing conglomerate Baoshan Iron & Steel Company (Baosteel) signed a joint venture agreement in May 2023 to establish an integrated steel plate manufacturing complex in Saudi Arabia’s Ras Al-Khair Industrial City.

The facility is expected to have a production capacity of up to 1.5 million tonnes a year (t/y). It will mainly cater to industrial sectors such as pipelines, shipbuilding, rig manufacturing, offshore platform fabrication and tank and pressure vessel manufacturing, as well as the construction, renewables and marine sectors.

The plant will be equipped with a natural gas-based direct reduced iron (DRI) furnace and an electric arc furnace to reduce CO2 emissions from the steelmaking process by up to 60% compared to a traditional blast furnace. The DRI plant will be compatible with hydrogen without major equipment modifications, potentially reducing CO2 emissions by up to 90% in the future, Aramco says.

The partners have invited contractors to submit engineering, procurement, installation and construction proposals for the project, which are due by 30 July.

Separately, Indian industrial conglomerate Essar Group is advancing its planned $4bn Green Steel Arabia project, which will also be located in Ras Al-Khair. Essar’s integrated steel complex will have a production capacity of 4 million t/y, and a cold rolling capacity of 1 million t/y, along with galvanising and tin plate lines. The complex will also have two DRI plants, each with a production capacity of 2.5 million t/y.

In September 2023, Essar signed a memorandum of understanding (MoU) with Jeddah-based Desert Technologies to develop solar energy solutions to power its Green Steel Arabia project. Under the agreement, Essar and Desert Technologies will look to develop solutions for renewable energy generation – mainly solar photovoltaic power – and storage for the planned complex.

The parties will also explore opportunities for other similar projects in the region, Mumbai-headquartered Essar said at the time.

A third major clean steel project in the kingdom has been announced by Turkish steelmaker Tosyali Holding, which will invest up to $5bn in the venture. Tosyali said in January that it intends to produce steel with the help of green energy sources and will increase its solar energy output 10-fold to 2,500MW, up from the 240MW it currently uses.

Fuat Tosyali, Tosyali’s chairman, said the increase in solar output will be facilitated by a $1.5bn investment, as well as through plans to buy a stake in a hydrogen energy company.

UAE makes strides

Clean steel production efforts in the UAE have been led by Emirates Steel Arkan, the country’s largest steel manufacturer. The company has partnered with Japan's Itochu to develop a low-carbon iron processing plant in Abu Dhabi that will be capable of processing high-grade Brazilian iron ore into reduced iron, which will be sent to Japan.

The proposed plant will be built in collaboration with Japan’s JFE Steel and is expected to produce about 2.5 million metric tonnes a year of reduced iron starting in 2027. CSN Mineracao, a Brazilian company in which Itochu maintains a stake, will supply the iron ore.

Emirates Steel and Abu Dhabi National Energy Company (Taqa) have also started the concept design for an electrolyser plant that they are jointly developing. Powered by renewable energy, the plant will have a hydrogen output capacity of 160MW, which will be used in the production of steel.

Abu Dhabi aims to establish a large-scale steel production hub with an overall capacity of 15 million t/y. This projected capacity will be in addition to Emirates Steel Arkan's existing production level of 3.5 million t/y, according to the firm's group chief projects officer, Hassan Shashaa.

Meanwhile, Dubai-headquartered Liberty Steel signed an MoU in December 2023 with Abu Dhabi’s AD Ports Group to invest in a green iron production facility in Khalifa Economic Zones Abu Dhabi.

Under the MoU, the two companies will explore the establishment of a green iron production facility and related port infrastructure and conveyor system at Khalifa Port in Abu Dhabi. The MoU is part of Liberty’s early-stage concept development to convert its magnetite ore into green iron in the UAE, using gas and transitioning to green hydrogen once it becomes available at scale in the next decade.

Green steel producers [in Oman] could benefit from cheap, locally available green hydrogen feedstock

Oman’s green steel plans

The largest green steel project in Oman is being developed by Vulcan Green Steel (VGS), the steel arm of Vulcan Green, which is owned by India’s Jindal Steel Group. VGS broke ground on the estimated $3bn project in December 2023.

The planned facility, covering 2 square kilometres in the Special Economic Zone at Duqm (Sezad), will have two production lines of 2.5 million t/y each, comprising DRI units, an electric arc furnace and a hot strip mill. 

Set for completion by 2026, the planned facility will primarily utilise green hydrogen to produce 5 million t/y of green steel. This will make it the world’s largest renewable energy-based green steel manufacturing complex once it is commissioned.

Sezad could also host another large-scale green steel project if Japanese steel manufacturer Kobe Steel and Tokyo-based Mitsui & Company are able to achieve the final investment decision on a preliminary agreement they signed in April last year to develop a low-carbon iron metallics project.

The two Japanese firms agreed to conduct a detailed business study in line with the goal of commencing low-carbon dioxide iron metallics production by 2027. The project is expected to produce 5 million t/y of DRI using a process called Midrex, where DRI is produced from iron ores through a natural gas or hydrogen-based shaft furnace.

Green steel producers in the sultanate could benefit from cheap, locally-available green hydrogen feedstock if the Amnah consortium – which won the first land block contract that Hydrogen Oman (Hydrom) auctioned last year – achieves the financial investment decision on its planned project by 2026.

The estimated $6bn-$7bn project will supply green hydrogen to domestic and overseas steel producers, Amnah project director Mark Geilenkirchen told MEED last year.

The planned integrated facility is expected to have a capacity of 220,000 t/y of green hydrogen and will require up to 4.5GW of renewable energy capacity. Unlike other projects in the region that aim almost exclusively to export their green hydrogen derivative products such as ammonia, Amnah is considering converting or using green hydrogen to support sustainable steel production.

  • Team offers $c1.29/kWh for 2GW Sadawi solar IPP project

    21 October 2024

    A developer team that includes UAE-based Abu Dhabi Future Energy Company (Masdar) has submitted the lowest bid for a contract to develop the 2,000MW Al-Sadawi solar independent power project (IPP) in Saudi Arabia.

    The consortium, which includes South Korea's Korea Electric Power Corporation (Kepco) and China's GD Power Development, submitted a levelised cost of electricity of hals 4.847 ($c1.29) a kilowatt-hour (kWh) for the contract to develop the scheme, which is located in the Eastern Province.

    The second-lowest bidder is a team that includes China's SPIC Huanghe Hydropower Development and France's EDF Renewables, which offered to develop the project for $c1.31/kWh.

    Saudi Power Procurement Company (SPPC) received six proposals from companies for the contracts to develop and operate four solar photovoltaic (PV) IPP projects in Saudi Arabia in August.

    The projects, which have a total combined capacity of 3,700MW, are being tendered under the fifth procurement round of the kingdom's National Renewable Energy Programme (NREP).

    According to SPPC, the lowest and second-lowest bidders in the remaining schemes under round five of the NREP are:

    Al-Masaa solar IPP (Hail): 1,000MW

    • L1: SPIC/EDF Renewables (France): $c1.36/kWh
    • L2: AlJomaih Energy & Water (local) / TotalEnergies Renewables (France): $c1.40/kWh

    Al-Hinakiyah 2 solar IPP (Medina): 400MW

    • L1: SPIC/EDF: $c1.51/kWh
    • L2: Masdar/Kepco/Nesma:  $c1.57/kWh

    • L1: AlJomaih Energy & Water / TotalEnergies Renewables: $c1.78/kWh
    • L2: Masdar/Kepco/Nesma: $c1.89/kWh

    Saudi utility developer Acwa Power is not among the 23 companies that were prequalified to bid for the fifth round of NREP projects.

    US/India-based Synergy Consulting is providing financial advisory services to SPPC for the NREP fifth-round tender. Germany's Fichtner Consulting is providing technical consultancy services.

    The round five solar PV IPPs take the total capacity of publicly tendered renewable energy projects in Saudi Arabia to over 10,300MW. Solar PV IPPs account for 79%, or about 8,100MW, of the total capacity.

    Four wind IPPs, one of which has yet to be awarded, account for the remaining capacity.

    SPPC is procuring 30% of the kingdom's target renewable energy by 2030. Saudi sovereign wealth vehicle the Public Investment Fund (PIF) is procuring the rest through the Price Discovery Scheme. The PIF has appointed Acwa Power, which it partly owns, as principal partner for these projects.

    The Saudi Energy Ministry recently said that the kingdom plans to procure 20,000MW of renewable energy capacity annually, starting this year and until 2030.

  • Khazna expects to build more 100MW-scale data centres

    21 October 2024

     

    Register for MEED's 14-day trial access 

    The 100MW artificial intelligence (AI)-enhanced data centre being built in the UAE's northern emirate of Ajman is not the last for UAE-based data centre and cloud services provider Khazna Data Centres.

    "In the near future, we will be announcing other projects on the same scale or larger than the Ajman data centre," Gregory Jasmin, the firm's senior director of business development strategy, tells MEED.

    The executive says the 100MW data centre, once completed, makes Khazna Data Centres "by far the largest data centre developer and operator in the entire Gulf region".

    MEED previously reported that London-headquartered construction firm Laing O'Rourke had started construction on Khazna's latest data centre project in Ajman.

    The new facility is expected to cost about AED1bn ($272m) and be completed within 15 months. Etihad Water & Electricity Company will supply power to the Ajman data centre.

    Jasmin says the company exceeded its capacity target of 300MW by the end of 2023, up from 126MW in early 2022.

    The firm has grown significantly since 2020, when it had a capacity of just 40MW, following the 2021 merger of the data centre divisions of Khazna’s parent firm G42 and telecommunications firm e&, previously known as Etisalat.

    The company is also expanding its presence in other markets, including Saudi Arabia, Egypt and Kenya.

    "By the end of this year and the start of Q1 next year, we will be in many [more] geographies," says Jasmin.

    Asked about the top driver for the company's future expansion, the executive says: "AI, AI and more AI."

    He adds: "This is based on what the [UAE] leadership wants, which is to have the UAE at the forefront of the AI revolution and with G42, we sit at the core of the infrastructure that is needed for AI.

    "For many years, we were always looking to the West to see what we can do, but now we want to take the lead in building the infrastructure that is powering AI here in the UAE as well as globally," says Jasmin.

    As things stand, the government's AI push has increased interest in building data centre capacity, if not changed the landscape entirely for Khazna.

    In June 2022, the firm's CEO Hassan Al-Naqbi told MEED that increased digitalisation by government entities and enterprises, as well as the adoption of school- and work-from-home practices, mean that the Middle East region will continue to drive double-digit growth in demand for data centre services.

    In addition, the general mandate for regional governments to retain data within their national jurisdictions is also a major driver for the growth of data centre services in the region, which was nearly double the global average at the time.

    Green data centre

    Known for being a major energy consumer, there is a growing awareness of how data centres can be made more sustainable or greener, particularly due to the cooling requirements, which are especially crucial in the Gulf region.

    Jasmin says in some countries, such as Kenya, a 100% renewable energy powered data centre is now feasible.

    Khazna's facility in Kenya is powered by 100% renewable geothermal energy and can go from a scale of 100MW up to 1GW, because "we are located in a green energy park that is fed by renewable energy currently at 900MW, but with the potential to grow to up to 10GW".

  • Dubai Municipality seeks Tasreef partner

    18 October 2024

    Register for MEED's 14-day trial access 

    Dubai Municipality has issued a tender notice for a delivery partner to develop and implement a model tailored to the needs of the Tasreef programme, Dubai's planned AED30bn ($8.16bn) rainwater drainage network project.

    MEED understands that the request for proposals targets technical and engineering advisory companies.

    Dubai Municipality expects to receive bids by 7 November, Fahad Al-Awadhi, director of drainage system and recycled water projects department, Dubai Municipality, said in a recent social media post.

    According to Al-Awadhi, the Tasreef programme consists of three streamlines to enhance the effectiveness of Dubai's stormwater system:

    • Improvement of infiltration and sustainable drainage systems and artificial intelligence (AI) applications
    • Upgrade of stormwater systems in Deira, Bur Dubai and Jebel Ali
    • Proposed stormwater tunnels in Deira and Bur Dubai, as well as link tunnels in Jebel Ali

    In addition, the Tasreef programme will address storm event management, including raising awareness about storm impacts, implementing proactive risk control measures, developing marketing and procurement strategies and establishing communication plans. 

    Al-Awadhi added: "The proposed stormwater tunnels, links and terminal pump stations aim to enhance the stormwater network’s capacity by 700% to handle up to 65 millimetres of rainfall per day. This programme represents the largest rainwater collection project in a single system within the region."

    An early study is under way for Tasreef, which Sheikh Mohammed Bin Rashid Al-Maktoum, UAE Vice President and Prime Minister and Ruler of Dubai, approved in June.

    A source familiar with the project said that Dubai Municipality is inclined to consider a public-private partnership (PPP) procurement model for the project.

    Sheikh Mohammed's approval of Tasreef came two months after a storm in April inundated Dubai, causing widespread flooding and damage to infrastructure and property in certain areas.

    The project will raise the emirate-wide drainage network’s capacity to more than 20 million cubic metres of water a day. It is hoped that it will meet Dubai's needs for the next 100 years.

    The project is a continuation of drainage projects launched by Dubai in 2019, covering the Expo Dubai area, Al-Maktoum International Airport City and Jebel Ali.

    The rainwater drainage capacity through tunnels will reach 20 million cubic metres a day, with a flow capacity of 230 cubic metres a second.

    According to data from regional projects tracker MEED Projects, the Dubai Municipality Deep Tunnel Storm Water System (DTSWS) was first announced in 2014.

    It has several components, and the first two packages covering Jebel Ali were awarded in 2017 and 2018 and completed in 2022.

    The remaining packages of the master plan were on hold before the government's announcement on 24 June.

    The DTSWS project is separate from the Dubai Strategic Sewage Tunnels project, which is being developed under a PPP contracting model.
