Mozambique's giant Rovuma liquefied natural gas (LNG) project is once again emerging as one of Africa's most closely watched resource developments, with a new economic assessment suggesting the project could add an average of $11 billion annually to the country's gross domestic product over the next three decades.

“The gas from the Rovuma Basin is, without a doubt, the most significant opportunity the country has ever had to drive such development.” - Bernardo Aparício Standard Bank Mozambique CEO

The findings, published by Standard Bank Mozambique, underscore the scale of the opportunity represented by the ExxonMobil-led development in the offshore Rovuma Basin. While global attention has increasingly focused on critical minerals and energy transition metals, the report highlights how natural gas continues to play a pivotal role in Africa's industrialisation ambitions and economic development strategies.

For Mozambique, the project represents far more than another hydrocarbons investment. It is increasingly being viewed as a nation-building initiative capable of transforming public finances, accelerating infrastructure development, creating industrial clusters and strengthening the country's position in global energy markets.

From frontier discovery to global LNG province

The Rovuma Basin story began in the early 2010s when a series of world-class offshore gas discoveries transformed perceptions of Mozambique's resource potential.

Exploration campaigns by Eni and Anadarko Petroleum revealed gas resources estimated at between 150 trillion and 200 trillion cubic feet, placing the basin among the largest gas discoveries globally in recent decades. Those discoveries laid the foundation for three major LNG developments:

• The Coral South FLNG project, operated by Eni, which has already entered production
• The Mozambique LNG project led by TotalEnergies, currently being restarted following security-related disruptions
• The Rovuma LNG project led by ExxonMobil and Eni in Area 4

Together, the projects have the potential to position Mozambique alongside established LNG exporters such as Qatar, Australia and the United States over the long term. The Rovuma LNG development itself is expected to comprise two onshore liquefaction trains with a combined capacity of approximately 18 million tonnes per annum, targeting customers across Europe and Asia.

Security challenges delayed, but did not derail development

The project's path has been far from straightforward. The insurgency in Cabo Delgado province, which intensified from 2017 onwards, forced investors to reassess timelines and security arrangements across northern Mozambique.

Major developments were delayed as operators sought greater certainty regarding personnel safety, logistics and infrastructure security. However, the intervention of regional forces, including troops from the Southern African Development Community and Rwanda, significantly improved conditions around key project areas.

The stabilisation effort has renewed investor confidence and allowed operators to resume planning activities. Industry observers increasingly view the security situation as manageable, although continued vigilance remains essential. The recovery in project momentum has coincided with renewed global interest in LNG following disruptions to international energy markets and growing demand for diversified gas supply sources.

A partnership model built around scale

One of the defining characteristics of Rovuma LNG is the breadth of partnerships underpinning the development. The project is being advanced by the Area 4 concession partners, led by ExxonMobil and Eni, alongside key stakeholders including China National Petroleum Corporation, Galp Energia, Korea Gas Corporation and Empresa Nacional de Hidrocarbonetos, Mozambique's state-owned energy company.

These partnerships combine technical expertise, financing capability, market access and operational experience across multiple jurisdictions. The consortium structure reflects a broader trend across African resource development, where the scale and complexity of projects increasingly require collaboration between international operators, state entities, financiers and host governments.

Beyond the project consortium itself, financial institutions have emerged as critical partners. Standard Bank, which has long supported energy and infrastructure investments across Africa, argues that the full economic benefits of the development will depend on creating linkages between the LNG sector and the broader domestic economy.

Beyond gas: The bigger economic prize

Perhaps the most significant conclusion from Standard Bank's analysis is that most long-term economic benefits may emerge outside the gas sector itself. The bank estimates the project could support approximately 151,000 jobs through direct, indirect and induced economic activity while generating around $4 billion annually in tax revenues and contributing roughly $9 billion each year to Mozambique's balance of payments. More importantly, economists argue that LNG can serve as a catalyst for wider industrialisation.

Reliable domestic gas supplies could underpin:

•    Fertiliser production
•    Petrochemical manufacturing
•    Gas-to-power projects
•    Industrial parks
•    Export-oriented manufacturing
•    Transport and logistics hubs

The experience of countries such as Malaysia and Qatar demonstrates that LNG developments generate the greatest value when governments successfully channel revenues into broader economic diversification strategies. For Mozambique, the challenge will be converting resource wealth into long-term productive capacity rather than relying solely on commodity exports.

Infrastructure corridors could become development engines

The LNG industry is already reshaping infrastructure planning across northern Mozambique. Ports, roads, airports, power networks and telecommunications systems developed to support gas projects could become foundational assets for wider economic growth. This mirrors a broader theme emerging across African resource development: major extractive projects increasingly serve as anchors for regional economic corridors.

The concept is like developments such as the Lobito Corridor in Angola, Zambia and the Democratic Republic of Congo, where infrastructure built for resource exports is increasingly viewed as a platform for industrial development and regional trade.

If effectively integrated into national planning frameworks, the infrastructure associated with Rovuma LNG could unlock investment opportunities across multiple sectors.

The global energy transition creates a window of opportunity

The project's timing is particularly significant. While renewable energy deployment continues to accelerate globally, natural gas remains widely viewed as a transition fuel capable of supporting energy security and reducing reliance on higher-emission fuels such as coal.

Europe's efforts to diversify energy supplies following geopolitical disruptions have strengthened demand for new LNG sources, while rapidly growing Asian economies continue to require substantial volumes of natural gas to support industrialisation and urbanisation. This dynamic has created a potentially favourable market environment for new LNG developments entering production during the coming decade.

For Mozambique, the opportunity lies in monetising its resources while global demand remains robust and before longer-term energy transition pressures begin to constrain investment in new hydrocarbon projects.

Et maintenant ?

Attention is now focused on the project's anticipated final investment decision. ExxonMobil has indicated that improving security conditions and ongoing engagement with the Mozambican government have strengthened confidence in moving the development forward. Should the project proceed on schedule, construction activity would rank among the largest industrial undertakings ever seen in sub-Saharan Africa.

Yet industry analysts caution that success will ultimately be measured not by LNG export volumes alone, but by the extent to which the project creates lasting economic value beyond the hydrocarbons sector.

The central question facing Mozambique is no longer whether the Rovuma Basin contains world-class resources. That has already been proven.

The challenge now is whether one of Africa's largest energy projects can become the foundation for a broader industrial transformation. If Standard Bank's projections prove accurate, the answer could reshape not only Mozambique's economy, but also perceptions of how large-scale resource developments can drive sustainable growth across Africa.
