Spanish firm to build world’s largest ammonia tanks at Neom

23 November 2023

Spanish engineering company Emypro has been awarded a civil sub-contracting deal for the construction of green ammonia storage tanks as part of the Neom green hydrogen project.

The project’s scope includes the installation of two tanks, and work will start in December 2023, according to a statement from the company.

“It must be emphasised that the ammonia storage tanks will become the two largest in the world to store green ammonia for the production of electricity through hydrogen,” the company said.

The contract for the tanks was awarded by Luxembourg-headquartered Man Enterprise, which is the main contractor for a larger ammonia tanks project with a scope that includes:

  • Construction of two ammonia storage tanks
  • Construction of a pumping station
  • Construction of a control room
  • Laying interconnecting pipelines and flowlines
  • Infrastructure works
  • Installation of surface facilities
  • Construction of associated facilities

Neom Green Hydrogen Company (NGHC) awarded the main contract for the larger ammonia tank project in June 2022. It is believed to have a value of $60m.

NGHC is a consortium of Saudi Arabia’s Acwa Power, Neom and US-based Air Products.

Xavi Marti, the managing director of Emypro, said: “I would like to thank Man Enterprise and Air Products for the trust placed in Emypro, recognising our technical and management capacity for the development of a project of this magnitude.”

He added: “We are in a moment of global change at an energy level and these achievements allow us to position ourselves as one of the leading companies in the sector, executing in this project the two ammonia tanks with the highest capacity in the world, to date.

“In a world as competitive and global as the one we live in, it is not easy to achieve this type of project, but little by little we are making our way.

“We have recently completed our participation with the engineering, supervision and construction of molten salt storage tanks in what, today, is considered the largest thermosolar plant in the world, for Dewa, ​​and now we are facing another important challenge in Neom (Saudi Arabia) with the full confidence of being able to develop, with the same success as in Dubai, the contract that has been awarded to us.”

In December last year, NGHC announced signing facility agreements with local, regional and international banks for the $8.4bn integrated green hydrogen and ammonia facility in Neom.

The Neom green hydrogen and green ammonia project includes 20MW of electrolysers to produce 600 tonnes of green hydrogen a day, an air separation unit (ASU) to produce nitrogen and a process plant to convert hydrogen into 1.2 million tonnes of ammonia a year.

It also includes renewable energy plants, battery storage and power transmission network infrastructure.

Air Products is the main engineering, procurement and construction (EPC) contractor for the entire integrated green hydrogen and ammonia facility, which will require a total investment of $8.4bn.

Acwa Power and Air Products signed limited notice to proceed (LNTP) agreements for the $900m EPC contract for the project in April 2022.

The agreements include an in-kingdom LNTP for the EPC contract between NGHC and Air Products Middle East Industrial Gases; and an out-of-kingdom LNTP for the EPC contract between NGHC and Air Products Equipment.

A power infrastructure deal with India’s Larson & Toubro (L&T) is understood to be a sub-contract with Air Products.

In June 2021, US-headquartered Baker Hughes announced it would supply Air Products with advanced compression technology for the facility’s electrolyser plant.

  • Oman’s Barka 5 IWP solar plant begins full operations

    1 May 2026

    Spain’s GS Inima has begun permanent operations at the solar photovoltaic (PV) plant serving the Barka 5 independent water project (IWP) in Oman.

    The solar facility is the third of its kind in Oman to power a large-scale desalination facility through a self-supply model.

    In a statement, GS Inima said it will provide up to 50% of the desalination plant’s electricity needs during daytime operations, improving efficiency and reducing reliance on external power sources.

    The PV plant has an installed capacity of 6.5MWp. It is designed to optimise energy consumption at the adjacent reverse osmosis desalination facility.

    The project was developed by GS Inima in collaboration with local firm Nafath Renewable Energy as the engineering, procurement and construction (EPC) contractor. China-based OCA Global provided owner’s engineering services.

    The Barka 5 IWP has a desalination capacity of approximately 100,000 cubic metres a day.

    GS Inima won the contract to develop the Barka 5 IWP project in November 2020. As previously reported, financial close was reached in 2022, and construction of the facility was completed in 2024.  

    The self-supply solar PV plant is equipped with 10,504 bifacial modules supplied by China’s Jinko Solar. These are mounted on fixed structures provided by Mibet Energy.

    Power is managed through 18 Sungrow inverters with a total capacity of 320kWac each, while electricity is fed into the desalination plant through an 11kV connection.

    The integration of solar power supports the efficiency of the Barka 5 facility, which has an energy consumption rate of 2.7kWh per cubic metre.

  • Qiddiya receives high-speed rail PPP prequalifications

    1 May 2026

    Register for MEED’s 14-day trial access 

    Saudi Arabia’s Royal Commission for Riyadh City, in collaboration with Qiddiya Investment Company (QIC) and the National Centre for Privatisation & PPP, received prequalification statements from firms on 30 April for the public-private partnership (PPP) package of the Qiddiya high-speed rail project in Riyadh.

    This follows the submission of prequalification statements for the engineering, procurement, construction and financing (EPCF) package on 16 April, as reported by MEED.

    The prequalification notice was issued on 19 January, and a project briefing session was held on 23 February at Qiddiya Entertainment City.

    The Qiddiya high-speed rail project, also known as Q-Express, will connect King Salman International airport and the King Abdullah Financial District (KAFD) with Qiddiya City. The line will operate at speeds of up to 250 kilometres an hour, reaching Qiddiya in 30 minutes.

    The line is expected to be developed in two phases. The first phase will connect Qiddiya with KAFD and King Khalid International airport.

    The second phase will start from a development known as the North Pole and travel to the New Murabba development, King Salman Park, central Riyadh and Industrial City in the south of the city.

    In November last year, MEED reported that more than 145 local and international companies had expressed interest in developing the project, including 68 contracting companies, 23 design and project management consultants, 16 investment firms, 12 rail operators, 10 rolling stock providers and 16 other services firms.

    In November 2023, MEED reported that French consultant Egis had been appointed as the technical adviser for the project. UK-based consultancy Ernst & Young is acting as the transaction adviser, and Ashurst is the legal adviser.

    Qiddiya is one of Saudi Arabia’s five official gigaprojects and covers a total area of 376 square kilometres (sq km), with 223 sq km of developed land.

  • Bid deadline extensions hint at tighter project market

    1 May 2026

    Commentary
    Mark Dowdall
    Power & water editor

    There has been a steady run of bid deadline extensions across major power and water projects in recent weeks.

    The latest is the Al-Dibdibah and Al-Shagaya solar independent power producer (IPP) plant in Kuwait, where the submission date has been moved again to 31 May, following an earlier shift from February to the end of April. Similarly, bidding for the first phase of the Al-Khairan IWPP has also been extended.

    In Bahrain, bidding for the 1.2GW Sitra IWPP has been pushed back by another month to 17 May, having already been under main contract tender since last August.

    Meanwhile, in Dubai, contractors have been given additional time to submit bids for both the Jebel Ali sewage treatment plant expansion and a dams rehabilitation project in Hatta.

    Individually, these shifts are not unusual, and extensions are a routine part of the procurement cycle, especially with large, capital-intensive schemes.

    However, amid regional tensions and increasingly complex risk profiles, stakeholders are having to weigh up how much they can absorb, whether that is performance guarantees, financing exposure or delivery risk.

    For contractors and developers, this could mean looking more closely at supply chains, insurance costs and the potential for disruption. Lenders, too, are likely taking a more measured view on long-term exposure.

    This caution can show up in the bid process. More internal approvals, more conservative pricing, and in some cases, perhaps a hesitation to commit altogether.

    At the same time, strong pipelines across the GCC mean contractors are not short of work. Firms can afford to be selective, focusing on projects where risk and return are better aligned.

    Clients, in turn, face a choice. Push ahead with more limited competition or extend and try to draw in stronger participation. Most appear to be opting for the latter.

  • Saudi Arabia launches $2bn Jawharat Al-Arous project

    1 May 2026

    Saudi Arabia has launched Jawharat Al-Arous, an SR8bn ($2bn) private-sector-led residential development in north Jeddah.

    The scheme covers 107 million square metres and comprises 18 residential neighbourhoods planned to accommodate more than 700,000 residents. It will provide more than 80,000 residential and commercial plots.

    The masterplan also includes 41 government-backed infrastructure and service zones to support large-scale urban expansion.

    The project was unveiled by Mecca Region Governor Khalid Al-Faisal and will be overseen by Saud Bin Mishaal Bin Abdulaziz.

    According to a recent report by real estate firm Cavendish Maxwell, Jeddah’s residential stock stood at about 1.09 million units at the end of 2025, following the completion of around 4,000 units that year.

    An expanding pipeline of about 18,000 units in 2026 and 22,000 units in 2027 is expected to bring total stock to around 1.14 million units by 2027, gradually adding supply without destabilising market equilibrium.

    GlobalData expects the Saudi construction industry to grow by 3.6% in real terms in 2026, supported by increased foreign direct investment (FDI) and investment in the housing and manufacturing sectors.

    The residential construction sector is forecast to grow by 3.8% in real terms in 2026 and to record an average annual growth rate of 4.7% between 2027 and 2030, supported by Saudi Vision 2030’s goal of increasing homeownership from 65.4% in 2024 to 70% by 2030, including through the delivery of 600,000 homes by 2030.

  • Damage to US bases in region expected to cost more than $15bn

    1 May 2026

    The $25bn estimate a Pentagon official gave US lawmakers on 29 April did not include the cost of repairing damage to US bases in the Middle East, and the real cost of the war is likely to be between $40bn and $50bn, according to CNN.

    That would put the cost of repairing bases and replacing destroyed assets at between $15bn and $25bn.

    Jules Hurst III, the Pentagon official serving as the agency’s comptroller, told the House Armed Services Committee that “most” of the $25bn he cited had been spent on munitions. Defence Secretary Pete Hegseth declined to say whether the figure included repairs to damaged US bases.

    Iranian strikes across the Gulf in the early days of the war significantly damaged at least nine US military sites in 48 hours, hitting facilities in Bahrain, Kuwait, Iraq, the UAE and Qatar.

    Six US servicemembers were killed in an attack on a command post in Kuwait, and 20 more were injured.

    Three sources told CNN that the figure provided to the House Armed Services Committee did not include the cost of rebuilding US military installations and replacing destroyed assets.

    One source said the true cost would likely be between $40bn and $50bn.

    US contractors such as KBR and Fluor, as well as local firms, are likely to be among the leading contenders for contracts to repair and rebuild US bases in the region.
