For decades, the name Saudi Aramco has been synonymous with one thing: oil. As the world’s largest integrated oil and gas company and the financial engine of the Kingdom of Saudi Arabia, its identity is deeply rooted in traditional fossil fuels. However, as the world confronts the immense challenge of climate change and begins a multi-decade energy transition, a fascinating and complex paradox has emerged. The planet’s biggest oil producer is now making massive, multi-billion-dollar investments in the future of green and low-carbon energy.
This is not a story of a company abandoning its core business. Instead, it is a pragmatic and calculated strategy to navigate the complexities of the 21st-century energy landscape. Aramco is pursuing a dual mandate: to continue supplying the conventional energy the world needs today while simultaneously investing in the sustainable energy systems of tomorrow. This is a look inside the multi-faceted strategy of an energy giant in transition.
Introduction
Welcome to your in-depth analysis of Saudi Aramco’s significant investments in green and low-carbon energy. The purpose of this guide is to provide a clear and detailed overview of the key pillars of the company’s sustainability strategy as it stands in mid-2025. The core thesis is that Aramco is executing a pragmatic, “all-of-the-above” approach to the energy transition. This strategy is built on four key pillars: developing large-scale renewable power, pioneering the market for “blue” hydrogen and ammonia, investing heavily in carbon capture technology, and funding the next generation of climate tech through its venture capital arm.
The Dual Mandate: Meeting Today’s Energy Needs While Investing in a Lower-Carbon Future
Before diving into the specifics, it’s crucial to understand Aramco’s overarching philosophy. The company’s leadership maintains that the global energy transition will be gradual and will require a continued, stable supply of oil and gas for decades to come. Therefore, their strategy is not to divest from fossil fuels but to work on two parallel tracks:
- Decarbonize their existing operations by reducing the carbon intensity of their oil and gas production.
- Invest in new, lower-carbon energy sources that will become a significant part of their business over the long term.
This dual mandate informs every investment decision they make in the green energy space.
Pillar 1: Building a Renewable Energy Powerhouse
Aramco is a key player in Saudi Arabia’s ambitious “Vision 2030” plan, which has a target of generating 50% of the Kingdom’s electricity from renewable sources by 2030.
Domestic Solar and Wind Projects
Aramco is partnering with Saudi Arabia’s Public Investment Fund (PIF) and leading renewable energy developers like ACWA Power to develop massive solar and wind projects across the Kingdom.
- Al Shuaibah Solar Projects: Aramco is a strategic partner in the development of the Al Shuaibah 1 and Al Shuaibah 2 solar power plants, which, when completed, will have a combined capacity of over 2.6 gigawatts, enough to power hundreds of thousands of homes.
- Sudair Solar Plant: The company is also involved in the Sudair Solar PV plant, another one of the largest solar projects in the world.
A Strategic Domestic Transformation
The primary goal of these massive renewable energy projects is to transform Saudi Arabia’s domestic energy consumption. By powering its own cities and industries with solar and wind, the Kingdom can significantly reduce the amount of crude oil it burns for domestic power generation. This frees up more of its most valuable resource—oil—to be sold on the export market, making it both an environmental and an economic win for the company and the country.
Pillar 2: Pioneering the “Blue” Hydrogen and Ammonia Market
While renewable electricity is a key focus, Aramco is making a huge strategic bet on a lower-carbon fuel that leverages its existing expertise in natural gas: blue hydrogen and blue ammonia.
The “Blue” vs. “Green” Distinction
It’s important to understand the difference between the two main types of “clean” hydrogen:
- Green Hydrogen: Is produced by splitting water using electricity from renewable sources like solar or wind. It is 100% carbon-free.
- Blue Hydrogen: Is produced from natural gas through a process that does release CO2. However, this CO2 is captured and stored underground, preventing it from entering the atmosphere.
Aramco’s Bet on Blue Ammonia
Aramco is positioning itself to be the world’s leading producer and exporter of blue hydrogen and, more specifically, blue ammonia. Ammonia (NH3) is a compound of hydrogen and nitrogen that is much easier and cheaper to transport over long distances than pure hydrogen.
- Global Export Deals: Aramco has already produced and shipped the world’s first cargoes of blue ammonia to customers in Japan and South Korea, who plan to use it to co-fire their power plants, reducing their carbon emissions.
- Leveraging Existing Strengths: This strategy allows Aramco to use its vast natural gas reserves and its decades of experience in chemical production and global shipping to create a new, lower-carbon product line.
The Role of Carbon Capture
The entire blue hydrogen and ammonia strategy is critically dependent on the success of Aramco’s investments in large-scale carbon capture technology, which is the next pillar of their strategy.
Pillar 3: A Massive Investment in Carbon Capture, Utilization, and Storage (CCUS)
Aramco views CCUS as one of the most critical technologies for achieving a lower-carbon future, and it is investing billions to become a world leader in this field.
Decarbonizing Existing Operations
A primary goal of Aramco’s CCUS investments is to reduce the carbon intensity of its own operations. By capturing the CO2 produced during the oil and gas refining process, the company aims to deliver some of the lowest-carbon-intensity barrels of oil in the world.
The Jubail Carbon Capture Hub
The centerpiece of Aramco’s CCUS strategy is the development of a massive carbon capture and storage hub in the industrial city of Jubail.
- The Goal: The company is developing a facility that it aims will be able to capture and store up to 11 million tonnes of CO2 equivalent per year by 2035.
- How It Works: The hub will capture emissions from Aramco’s own industrial facilities as well as from surrounding third-party industrial plants. The captured CO2 will then be injected deep underground into saline aquifers for permanent storage. This project is set to be one of the largest CCUS hubs in the world.
Pillar 4: Funding the Future Through Venture Capital
Beyond its own large-scale projects, Aramco is also investing in the next generation of climate tech startups through its corporate venture capital arm, Aramco Ventures.
The Aramco Ventures Sustainability Fund
In 2023, Aramco launched its flagship $1.5 billion Sustainability Fund. This fund is dedicated to investing in startups and technologies that can support a stable and inclusive energy transition.
What Are They Investing In?
The fund is actively investing in a diverse portfolio of early-stage companies across the globe. The key investment areas include:
- Carbon Capture and Storage: New technologies that can lower the cost and increase the efficiency of capturing CO2.
- Renewable Energy: Innovations in solar, wind, and energy storage.
- Energy Efficiency: Technologies that help industries reduce their energy consumption.
- Hydrogen and Low-Carbon Fuels: Startups that are developing new ways to produce and transport hydrogen and other sustainable fuels.
This venture capital arm acts as a strategic listening post for Aramco, giving it early access to the disruptive technologies that will shape the future of energy.

Conclusion
Saudi Aramco’s approach to the green energy transition is a pragmatic, multifaceted, and calculated strategy designed to ensure its long-term survival and influence in a changing world. While the company remains firmly an oil and gas behemoth, it is not ignoring the global shift toward a lower-carbon future. Through its massive, multi-billion-dollar investments in domestic renewable power, its ambitious plan to dominate the global market for blue hydrogen and ammonia, its leadership in developing large-scale carbon capture, and its strategic funding of next-generation climate tech, Aramco is ensuring it will remain a powerful and central player in the global energy landscape for decades to come, no matter what the future of energy looks like.
