The journey towards net zero

26 October 2022

Published in partnership with

The most pressing concern in the race to net zero is the need to reduce carbon emissions. According to the International Panel on Climate Change (IPCC), carbon dioxide (CO2) accounts for 76 per cent of total global greenhouse gas emissions, of which 65 per cent is a direct result of fossil fuel and industrial processes.

Lowering CO2 output would therefore have the biggest impact on global warming.

The Middle East is central to this process. Although the region accounts for only 7 per cent of total global CO2 output, its emissions are some of the world’s highest on a per capita basis. 

In 2021, for example, per capita emissions in the Middle East were 8 tonnes, compared with 2.3 tonnes in South America, 4.1 tonnes in Asia and 5.6 tonnes in Europe. These figures exclude the environmental impact of oil and gas exports from the region. 

It is also an issue the region can no longer afford to ignore as it is particularly prone to climatic changes including reduced rainfall, heatwaves and increasingly severe weather events, such as the cyclones that have hit Oman in recent years. 

Reality bites

The subject was a key talking point at the Siemens Energy Middle East & Africa Energy Week event in June, where attendees discussed decarbonisation and the government targets – 2050 for the UAE and Oman, and 2060 for Saudi Arabia and Bahrain – set as deadlines to reach net zero. 

A startling finding from the event was the gap between perceptions and reality regarding what has been achieved so far in cutting emissions.

As part of Siemens Energy’s survey for its Middle East & Africa Energy Transition Readiness Index, when asked to quantify CO2 reductions in their country today and what they will be in 2030 compared to 2005, participants estimated that total emissions had fallen by 23 per cent on average over the past 17 years. Only one-third correctly answered that emissions had not fallen at all.

In fact, the opposite has taken place. Between 2005 and 2020, total global CO2 emissions increased by 50 per cent to almost 3.5 billion tonnes, according to the authoritative BP Statistical Review of World Energy 2021.

“This year, many reports were issued of which the most important is the IPCC report,” said Mohamed Nasr, director of the Environment & Sustainable Development Department at Egypt’s Foreign Affairs Ministry and lead negotiator for Egypt at Cop27, speaking at the Energy Week.

“All [of the reports] stressed that we are not on track to keep climate change below 2 degrees, or even keep the 1.5 degrees target within reach. More work needs to be done.”

Work in progress

A second poll revealed that attendees expected emissions to fall to 39 per cent of their 2005 levels on average, a figure that is highly unlikely to be reached in just eight years. 

This is especially the case given that carbon emissions must be cut across the board. Although the region is making good progress on the development of renewable energy production, there has been much lower momentum in other areas. 

For example, cement production is estimated to account for between 7 per cent and 10 per cent of total carbon emissions, but despite this, there has been little in the way of new regulations on government cement output in the region. 

Overall, in 2021 the industrial sector directly accounted for about a quarter of total global greenhouse emissions equivalent to 9.4 gigatonnes, a rise of 193 megatonnes on the previous year, according to the International Energy Agency (IEA). Iron, steel and cement production comprised more than half this figure.

The industry itself recognises more needs to be done and is implementing a range of policies and agreements to act co-operatively on reducing its climatic impact.

In early September for instance, the International Renewable Energy Agency (Irena) and international companies including Siemens Energy as a co-founder, Tata Steel, Enel Green Power, Technip Energies, Taqa and Eni launched the global Alliance for Industry Decarbonisation. The new alliance is aimed at accelerating net-zero ambitions and the decarbonisation of industrial value chains in accordance with the Paris Agreement. To date, 20 members have joined the alliance to work towards the same vision.

“Climate action needs industry leaders,” said Francesco La Camera, Irena director-general. “This Alliance stands for the growing commitment of global industry to act on decarbonisation and unlock opportunities that come with a green industrialisation through renewables and other transition-related technologies like green hydrogen.

“By standing together we send a clear signal of solidarity ahead of Cop27 and we invite new partners to join our common vision.”

Ultimately, we must remember that every tonne of CO2 we emit into the atmosphere will need to be removed

Renewables focus

Closer co-operation is a step in the right direction, but is just one element in a range of measures that need to be implemented. 

When ranking the energy initiatives to reach net zero as part of the Transition Readiness Index, the Energy Week participants identified three other priorities with the highest beneficial impact: accelerating the development of renewable energy projects; reinventing energy business models; and implementing energy storage solutions. 

The focus on renewables reflects the raft of utility-scale solar, hydro and wind schemes across the Middle East and Africa. In all, there are more than 500 projects planned or under way, with a total capital investment value of more than $510bn. 

But there has been less progress on the other two main priorities. Energy storage solutions have gained little traction to date in the region, although Dubai’s innovative 250MW pumped hydro energy storage project in Hatta could become a template for others to follow when it comes to grid-connected storage capacity. 

Nonetheless, with grids operated by centralised state utilities and renewable projects at a stage where they support conventional energy production rather than replace it, there is still some way to go before storage systems become more widespread.

For now, the principal opportunity for energy storage systems is for captive use at off-grid demand centres – for example, at Saudi Arabia’s gigaprojects along the Red Sea coast, such as the Red Sea Project and Neom. Entirely dependent on renewable energy production, the projects may require stored energy when weather conditions are unfavourable or during periods of peak demand. 

Diversifying the energy business model is unsurprisingly a key priority given the region’s reliance on hydrocarbon exports. Over the past 18 months, the development of a hydrogen industry has emerged as the pre-eminent trend to enhance the Middle East’s position as the leading source of global energy supplies. 

Today, there are some 46 world-scale hydrogen projects across the Middle East and Africa worth well in excess of $50bn. Although only two are under construction, the hydrogen industry is expected to grow massively in the region over the next decade.

This is just as well as time is fast running out if the world is to avoid a climatic emergency. 

As Dietmar Siersdorfer, managing director of Siemens Energy Middle East and the UAE, puts it: “Ultimately, we must remember that every tonne of CO2 we emit into the atmosphere will need to be removed.”

  • Contractors submit bids for next phase of Duba port

    2 June 2023

    Contractors have submitted bids for the next phase of the Duba port expansion at Oxagon industrial city.

    The bidders are Belgium’s Deme with Greece’s Archirodon; Van Oord of the Netherlands with South Korea’s Hyundai Engineering & Construction; a Belgian joint venture of Jan de Nul and Besix; Netherlands-based Boskalis with France’s Soletanche Bachy; South Korea’s Daewoo; and China Harbour Engineering Company.

    The tender for the project’s second phase follows the award of a contract to deliver the first phase of the port expansion. A team of Boskalis, Besix and the local Modern Building Leaders (MBL) was awarded that estimated SR3bn ($800m) contract in mid-January.

    The scope of the Duba port expansion package includes excavation and dredging, revetments for channel widening, demolition, container terminal quay expansion and earthworks, in addition to the development of a flexible quay, a roll-on/roll-off (RoRo) berth and quay walls to a marine services berth and a coast guard facility.

    Jacobs is the main design consultant, with Moffatt & Nichol, IGO and Trent as the main sub-consultants.

    Contractors are preparing to submit bids in June for a contract to build tunnels connecting the offshore elements of the Oxagon industrial city at Neom to the mainland.

    The design-and-build contract involves digging a 6.5-metre-diameter tunnel using a tunnel boring machine (TBM) under the sea that will link the Neom Connector with the offshore elements of Oxagon port. It will house utilities including water pipelines, fibre optic cables and electricity cables.

    Crown Prince Mohammed bin Salman launched Oxagon in late 2021. It will include onshore elements as well as floating structures offshore. Construction works on the 48 square-kilometre, eight-sided industrial city have already started.

    An expanded Duba port is a critical component of Oxagon and the broader Neom development, as it will allow greater volumes of materials to be imported for the project. With an expected investment value of $500bn, Neom is the largest programme of construction work in the world.

  • Egypt makes steady progress on Assiut refinery

    2 June 2023

    Egypt is making steady progress on the $2bn hydrocracking complex package that forms part of the wider Assuit oil refinery upgrade project, according to industry sources.

    Assiut Oil Refining Company (ASORC), a subsidiary of state-owned Egyptian General Petroleum Corporation (EGPC), is the project operator.

    “Work on the main units is continuing with no significant issues,” said one source.

    During 2021, the project faced disruption due to issues related to the Covid-19 pandemic.

    In 2023, many projects in Egypt’s oil and gas sector have been disrupted by currency issues due to the declining value of the Egyptian pound.

    Most of the projects that the currency issues have significantly impacted have been in their early stages, with the problems related to the procurement of materials and equipment.

    France’s Technip Energies is the main contractor performing engineering, procurement and construction (EPC) works on the Assiut hydrocracking complex, as part of a $2bn contract it was awarded by ASORC in February 2020.

    In April 2021, Switzerland-based Burckhardt Compression announced being selected by Technip Energies as the gas compressor supplier for the hydrocracker package.

    ASORC held a kick-off meeting for the project in September 2020.

    Egyptian contractors Enppi and Petrojet are supporting Technip Energies on the project. Enppi has undertaken the engineering work, while Petrojet is carrying out construction work.

    In 2021, contractors completed the construction of a $450m high-octane gasoline complex in the Assiut governorate as part of the broader $3.8bn Assuit oil refinery upgrade project.

    Assiut refinery

    The Assiut hydrocracking complex will be one of Egypt’s major strategic refineries, and will help meet growing local demand for cleaner products.

    The project will also become the largest oil refining facility to be implemented in Upper Egypt so far.

    Once completed, the project will transform lower-value petroleum by-products, such as mazut, into cleaner, higher-value products.

    It is expected to have an output of about 2.8 million tonnes a year of Euro-5 diesel, in addition to other petroleum products.

  • Mawani implements $950m of Saudi port projects

    2 June 2023

    Saudi Ports Authority (Mawani) is implementing a series of projects over the coming 18 months as part of its efforts to improve and expand infrastructure at ports and increase their utilisation rates.

    The programme, worth about SR3.5bn ($950m), comprises just over 150 projects, of which 48 are strategic in nature, 90 infrastructure-focused and 14 targeting security enhancements.

    The most significant projects are:

    At Jeddah Islamic Port

    • A four-year contract to build a new road, interchanges and flyovers to link Gate 9 with the Al-Khumrah integrated logistics park.
    • Deepening over three years of the north basin approach channel to 14 metres and the construction of a bull nose dike

    At Ras al-Khair Port

    • Increasing the draft depth of berths 11 and 12 to 16 metres
    • A three-year job to widen and dredge the approach channel from 300 metres to 500 metres and deepen it by 3 metres to 19 metres

    Other key investments include installing integrated security systems at Jeddah Islamic Port and King Abdulaziz Port in Dammam and constructing a new 40MVA substation at King Fahd Port in Yanbu.

    The contracts are expected to be tendered and awarded by the end of 2024.

    Mawani’s planned investment comes on the back of several major contracts awarded over the past 12 months, including an agreement with DP World to set up the Al-Khumrah logistics park, the reconstruction and expansion of the first and second container terminals at King Abdulaziz Port, and the upgrade of berth infrastructure and draft depths at Jeddah Islamic Port and King Fahd Port.

  • Dubai unveils new masterplan for Palm Jebel Ali

    1 June 2023

    Dubai has released details of the new masterplan for Palm Jebel Ali, an artificial island located south of Jebel Ali Freezone.

    Double the size of Palm Jumeirah, Palm Jebel Ali will have 110 kilometres of shoreline and extensive green spaces. The development will feature over 80 hotels and resorts, along with a diverse range of entertainment and leisure facilities.

    Strategic masterplan

    The unveiling of the masterplan aligns with Dubai's commitment to doubling the size of its economy by 2033, as outlined in the Dubai Economic Agenda.

    The project, approved by Sheikh Mohammed bin Rashid al-Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, includes seven connected islands, catering to approximately 35,000 families. The development also emphasises sustainability, with 30 per cent of public facilities powered by renewable energy.


    MEED reported in January that local developer Nakheel had approached contractors to complete the reclamation works for Palm Jebel Ali.

    As with Palm Jumeirah, it is estimated that it could take around 20 years for Palm Jebel Ali to reach its full development potential. Nakheel has previously secured AED17bn ($4.6bn) in funding to expedite the development of various projects, including the Dubai Islands and other waterfront schemes.

    The upcoming dredging contract for Palm Jebel Ali is anticipated to involve 5-6 million cubic metres of material, contributing to the completion of the man-made offshore island.

    While reclamation work for Palm Jebel Ali is mostly finished, the project was put on hold in 2009. Nakheel had made some progress with infrastructure development, including the construction of bridges on the island by Samsung C+T.
