Energy: Aramco vs. ExxonMobil

 

Global Energy Hegemony and Technological Change

Global energy lies at the foundation of national economies and industrial systems and is a core determinant of international power. Since the Industrial Revolution, an energy regime centered on fossil fuels has taken shape, and by the twentieth century oil had become an indispensable resource for economic growth and military strength. Within this historical trajectory, countries that possess energy resources and corporations that develop and distribute them have played a decisive role in shaping the global economy and international politics.

In particular, Saudi Aramco of Saudi Arabia and ExxonMobil of the United States stand as the world’s largest oil companies, representing the Middle East and the United States respectively as dominant energy powers. The two companies compete across oil and gas production volumes, technological innovation, investments in renewable energy, and carbon-neutral strategies, exerting a profound influence on the future direction of the global energy market.

Saudi Aramco is Saudi Arabia’s national oil company, established in 1933 through an agreement between Standard Oil of California and the Saudi government. In 1944, its name was changed to Aramco, an abbreviation of the Arabian American Oil Company. Beginning in 1973, the Saudi government gradually acquired equity stakes, and in 1988 Aramco was fully nationalized. Today, Aramco is the company with the world’s largest proven oil reserves and consistently ranks at the top globally in terms of daily crude oil production and revenue. Owing to Saudi Arabia’s geopolitical position and extremely low production costs, Aramco maintains a highly stable supply chain and exerts substantial influence over global oil price formation.

By contrast, ExxonMobil represents the United States as a global oil major. It was created in 1999 through the merger of Exxon and Mobil. Exxon originated as one of the companies spun off from John D. Rockefeller’s Standard Oil, while Mobil also traces its roots to the Standard Oil system. Over time, the two firms grew independently, expanding their global footprint in the oil industry. Their historic merger in 1999 produced the world’s largest publicly traded oil company. ExxonMobil is particularly strong in proprietary technology, refining, and petrochemicals, and possesses world-class capabilities in exploration and drilling.

Although both Aramco and ExxonMobil rank among the world’s largest oil producers, their business structures and operational models differ significantly. Aramco holds the largest oil reserves globally and produces on average more than 10 million barrels of crude oil per day. Backed by Saudi government support and vast oil fields, it can produce oil at extremely low cost. ExxonMobil, by contrast, has relatively smaller reserves and operates exploration and development projects across North America, South America, Africa, and Asia. Its daily production of approximately four to five million barrels is lower than Aramco’s, but it has expanded output through shale oil and gas development.

Aramco maintains a low-cost, high-volume production model centered on conventional oil fields while adopting advanced digital technologies to ensure operational stability. Its low production costs allow it to remain profitable even during periods of low oil prices. ExxonMobil, on the other hand, excels in deepwater drilling, liquefied natural gas (LNG), and shale oil development, leveraging advanced drilling technologies and sophisticated refining and petrochemical processes to maximize value creation. Following the U.S. shale revolution, ExxonMobil has aggressively pursued shale oil and gas projects, differentiating its strategy from that of traditional Middle Eastern producers.

As the global energy market shifts toward climate change mitigation and cleaner energy, Aramco and ExxonMobil have adopted divergent approaches. Although Aramco remains a traditional oil company, it has begun investing in hydrogen energy, solar power, and carbon capture technologies in line with Saudi Arabia’s Vision 2030 strategy. In particular, it aims to secure leadership in the future hydrogen economy through blue and green hydrogen production, while actively developing carbon capture and storage technologies. Nevertheless, its share of renewable energy investment remains relatively low, and its business structure continues to be heavily oil-centered, raising questions about the pace of its green transition.

ExxonMobil continues to maintain its refining and petrochemical businesses while focusing strongly on carbon capture and storage (CCUS). It has also introduced technologies to reduce carbon emissions from shale oil development and is expanding into areas such as biofuels, hydrogen, and lithium extraction. However, compared to other global energy companies, its investments in renewable energy remain relatively limited, and its dependence on fossil fuels continues to draw criticism.

Aramco and ExxonMobil, as representative oil companies of the Middle East and the United States, wield enormous influence over the global energy market. Aramco benefits from its role as a stable supplier of Middle Eastern oil, while ExxonMobil advances a diversified strategy grounded in U.S. technological innovation and shale oil development.

Looking ahead, the global energy market is expected to evolve toward decarbonization and renewable energy. Within this context, Aramco is seeking to transform into a cleaner energy company through hydrogen and carbon capture technologies, while ExxonMobil aims to sustain competitiveness through carbon reduction technologies and shale-based production.

Ultimately, the competitive dynamic between Aramco, which seeks to preserve traditional oil dominance, and ExxonMobil, which pursues energy transition through technological innovation, is likely to persist. The future of global energy hegemony will be shaped over the next ten to twenty years by the pace of development in renewable energy, the hydrogen economy, and carbon-neutral technologies.

Aramco: The World’s Largest Oil Company and the Middle East’s Resource Strategy

Saudi Aramco, the national oil company of Saudi Arabia, occupies a uniquely dominant position in the global energy market. Founded in 1933 through a partnership between Standard Oil of California and the Saudi government, Aramco adopted its current name in 1944 and was fully nationalized by 1988. Closely aligned with Saudi Arabia’s national strategy, Aramco has grown into the world’s largest oil producer and a central actor shaping Middle Eastern energy policy and the global oil market.

Aramco’s greatest strengths lie in its vast oil reserves and exceptionally low production costs. Saudi Arabia holds some of the world’s largest oil reserves, enabling Aramco to maintain a highly stable supply system. Its production costs, estimated at under USD 10 per barrel, are among the lowest globally. This cost advantage allows Aramco to remain profitable even during oil price downturns and gives Saudi Arabia leverage in global oil price negotiations.

Aligned with Saudi government policy, Aramco plays a critical role not only in the energy sector but also in the Kingdom’s broader economic and diplomatic strategy. Oil export revenues have historically underpinned Saudi Arabia’s economic development, funding infrastructure and industrial growth. To overcome the limitations of oil dependence, Saudi Arabia has launched Vision 2030, a comprehensive economic reform agenda, under which Aramco is pursuing diversification and investments in renewable energy.

Vision 2030 seeks to reduce reliance on oil exports and foster sustainable growth through non-oil industries. In this context, Aramco is expanding investments in hydrogen energy, solar power, and carbon capture and storage technologies. By developing blue and green hydrogen, Aramco aims to play a leading role in the global hydrogen market while integrating carbon-neutral technologies into its operations.

Nevertheless, Aramco’s renewable energy initiatives remain at an early stage, and significant challenges remain in shifting away from its oil-centric business model. Saudi Arabia continues to depend heavily on oil exports for foreign exchange earnings, and as long as global oil demand persists, crude oil will remain Aramco’s primary revenue source. Consequently, Aramco has adopted a dual strategy: maximizing oil production in the short term while pursuing a gradual transition toward cleaner energy over the long term.

Within the Middle East’s resource strategy, Aramco serves as a central instrument of Saudi energy diplomacy. As a leading producer within OPEC, Saudi Arabia plays a pivotal role in coordinating production cuts and increases to influence global oil prices. Aramco operationalizes this strategy, enabling Saudi Arabia to exercise economic and diplomatic influence through energy supply.

In periods of heightened oil market volatility, Aramco is essential to maintaining Saudi fiscal stability. During price declines, production adjustments help stabilize revenues; during price surges, increased exports generate windfall profits. Through this flexible approach, Aramco has become a cornerstone of Saudi economic stability and national strategy.

Aramco thus stands not merely as an oil company but as a key institution driving Saudi Arabia’s economic policy and the Middle East’s resource strategy. While maintaining unrivaled competitiveness in global oil markets, it is simultaneously exploring a transition toward hydrogen, carbon capture, and solar energy.

As global energy markets move toward decarbonization, Aramco faces the challenge of balancing its existing oil dominance with gradual energy transition. The direction it chooses will significantly influence not only Middle Eastern energy strategy but also the future contours of global energy hegemony.

ExxonMobil: U.S. Energy Technology and the Shale Revolution

ExxonMobil is a flagship U.S. energy company and a major force in the global energy market. Formed in 1999 through the merger of Exxon and Mobil, the company operates across oil and gas exploration, refining, petrochemicals, and emerging energy sectors. It played a central role in the shale revolution that propelled the United States to become the world’s largest oil and gas producer.

ExxonMobil’s origins trace back to the early days of the U.S. oil industry. After the 1911 antitrust breakup of Standard Oil, Exxon and Mobil evolved independently, building strong positions in refining and petrochemicals throughout the twentieth century. Their merger in 1999 created the world’s largest publicly traded oil company.

ExxonMobil operates extensive exploration and production activities worldwide, including deepwater and Arctic projects. Its advanced drilling and refining technologies enable high value-added production across oil, gas, and petrochemicals.

A defining turning point in ExxonMobil’s growth was the shale revolution of the early twenty-first century. Advances in hydraulic fracturing and horizontal drilling unlocked oil and gas resources previously considered uneconomical, transforming U.S. energy markets.

ExxonMobil entered the shale sector in earnest with its 2009 acquisition of XTO Energy, a major natural gas producer. It subsequently expanded shale operations in Texas, North Dakota, and New Mexico, particularly in the Permian Basin, significantly boosting U.S. energy output and reinforcing American energy independence.

The shale revolution reshaped U.S. energy policy by reducing dependence on Middle Eastern oil and enhancing geopolitical flexibility. Following the lifting of the U.S. crude export ban in 2015, ExxonMobil expanded exports of oil and LNG to Europe, Asia, and beyond, with U.S. LNG emerging as a key alternative to Russian energy supplies.

However, the rapid expansion of shale development raised environmental concerns, including groundwater contamination, induced seismicity, and methane emissions. In response, ExxonMobil has introduced technologies to reduce emissions and mitigate environmental impacts.

While maintaining its core oil and gas operations, ExxonMobil is developing long-term strategies for carbon neutrality. Compared to European peers such as BP and Shell, it has adopted a more conservative stance toward renewables, but it has invested heavily in CCUS technologies, along with biofuels, hydrogen, and lithium extraction.

CCUS is central to ExxonMobil’s decarbonization strategy, enabling continued fossil fuel use with reduced emissions. By collaborating with governments and industry partners, ExxonMobil aims to build large-scale CCUS infrastructure to remain competitive under increasingly stringent carbon regulations.

Driven by technological innovation and policy shifts, the U.S. energy sector continues to evolve, with ExxonMobil at its core. Having helped secure U.S. energy independence through the shale revolution, the company now faces the challenge of adapting to a decarbonizing global energy system.

Despite criticisms over limited renewable investment, ExxonMobil seeks to position itself as a sustainable energy company through carbon reduction technologies and diversification. It is likely to remain a major player in global energy markets as it navigates ongoing transitions.

Can Renewable Energy Disrupt Traditional Energy Hegemony?

Whether renewable energy can disrupt traditional energy hegemony has become one of the most pressing questions in the modern energy industry. As climate change mitigation and sustainable energy transition rise to the forefront of global policy agendas, renewable technologies such as solar, wind, hydrogen, and energy storage systems are expanding rapidly. At the same time, countries and corporations that have long dominated fossil fuel–based energy systems are reassessing their strategies.

The growth of renewables is accelerating to a degree that increasingly challenges fossil fuel industries. Solar and wind power costs have fallen sharply, in some regions undercutting coal and natural gas. According to the International Renewable Energy Agency (IRENA), solar power costs have declined by more than 90 percent since 2010, while wind power costs have fallen by over 70 percent. These trends suggest that renewables can evolve from supplementary sources into primary energy suppliers.

Policy support plays a critical role in this expansion. The European Union, United States, and China have all committed to carbon neutrality targets and implemented large-scale support measures. The EU aims for carbon neutrality by 2050, the U.S. supports renewables through the Inflation Reduction Act, and China has become the world’s largest producer of solar and wind power.

Despite this momentum, significant uncertainties remain. Intermittency remains the most serious challenge, as solar and wind generation fluctuate with weather conditions. Energy storage technologies, particularly batteries, are essential to addressing this issue, but current capabilities remain insufficient to fully replace fossil fuel–based reliability.

Infrastructure constraints also pose challenges. Global energy systems have been built around centralized fossil fuel generation, and integrating distributed renewable sources requires massive investment in grid modernization.

Geopolitics further complicates the transition. Fossil fuel hegemony has historically been rooted in geographically concentrated resources, empowering oil- and gas-rich regions. Renewables, by contrast, offer the potential for more decentralized energy production, theoretically weakening resource monopolies.

In response, traditional energy powers increasingly view renewables not as threats but as opportunities. Aramco and ExxonMobil exemplify this approach: Aramco integrates hydrogen and CCUS into its strategy, while ExxonMobil emphasizes carbon reduction technologies and gradual transition.

While renewables may not fully displace fossil fuel–based energy hegemony in the short term, their long-term potential is substantial. Success depends on advances in energy storage, hydrogen technologies, and infrastructure modernization, as well as the pace of technological innovation and policy alignment.

Renewable energy is already reshaping traditional energy power structures, though full transition remains complex. Over the coming decades, shifts in energy hegemony are likely to accelerate, driving profound structural changes in global energy markets.
