Renewable Energy Technology in Saudi Arabia: Solar Manufacturing, Green Hydrogen, Battery Storage, and Carbon Capture

The world’s largest oil exporter is making one of the world’s largest bets on renewable energy. Saudi Arabia’s commitment to clean energy technology is not a contradiction but a strategic calculation by a nation that understands both the finite nature of fossil fuels and the economic opportunity in the global energy transition. The Kingdom is investing tens of billions of dollars in solar manufacturing, green hydrogen production, battery storage systems, and carbon capture technology, positioning itself to be as dominant in the clean energy era as it has been in the age of oil.

The motivation is multifaceted. Domestically, Saudi Arabia consumes approximately 3.4 million barrels of oil equivalent per day for electricity generation and water desalination. Every barrel of oil burned domestically is a barrel that cannot be exported at international prices, representing a significant opportunity cost. Replacing domestic fossil fuel consumption with renewable energy frees up oil for export, generating additional revenue even as the global energy mix evolves.

Internationally, Saudi Arabia recognizes that the energy transition creates new markets worth trillions of dollars. The Kingdom’s solar resources are among the best on Earth. Its vast, uninhabited land areas can accommodate solar and wind installations at scales that densely populated countries cannot match. And its existing energy infrastructure, pipeline networks, port facilities, and technical expertise can be repurposed for clean energy export.

The Saudi Green Initiative, announced in 2021, provides the strategic framework for the Kingdom’s environmental and clean energy commitments. The initiative targets the generation of 50 percent of electricity from renewable sources by 2030, reaching net-zero greenhouse gas emissions by 2060, and planting 450 million trees. While the 2060 net-zero target has drawn skepticism from some environmental advocates, the pace of renewable energy deployment since the initiative’s announcement suggests that Saudi Arabia is serious about the transition.

Solar Energy: From Desert Sun to Manufacturing Hub

Saudi Arabia receives among the highest levels of solar irradiation of any country on Earth, with average direct normal irradiance exceeding 2,200 kilowatt-hours per square meter per year in the Kingdom’s sunniest regions. This natural endowment makes solar energy the most cost-effective source of new electricity generation in Saudi Arabia, with utility-scale solar projects routinely achieving costs below 2 cents per kilowatt-hour.

Utility-Scale Solar Development

The National Renewable Energy Program (NREP), managed by the Renewable Energy Project Development Office (REPDO), has overseen a rapid buildout of utility-scale solar capacity. Through a series of competitive tenders, the program has awarded contracts for more than 15 gigawatts of solar photovoltaic (PV) capacity, with projects at various stages of development across the Kingdom.

The Sudair Solar PV project, one of the world’s largest solar installations at 1.5 gigawatts, commenced operations in 2024. Located 150 kilometers north of Riyadh, the project generates enough electricity to power approximately 185,000 homes. The project achieved a record-low tariff of 1.239 cents per kilowatt-hour at the time of its award, demonstrating the extraordinary cost-competitiveness of solar energy in Saudi conditions.

Additional large-scale projects are under construction or in development across the Kingdom, with planned capacity exceeding 25 gigawatts by 2030. The projects use a combination of fixed-tilt and single-axis tracking solar panels, with tracking systems increasingly preferred for their ability to follow the sun’s path and increase energy yield by 15 to 25 percent.

Concentrated Solar Power

While photovoltaic technology dominates Saudi Arabia’s solar buildout, concentrated solar power (CSP) with thermal energy storage is being deployed for applications that require dispatchable generation. CSP systems use mirrors to concentrate sunlight and heat a working fluid, which drives a steam turbine to generate electricity. Thermal energy storage, typically using molten salt, allows CSP plants to continue generating electricity for hours after sunset.

The Dumat Al Jandal CSP project in the Al Jouf region combines a 700-megawatt solar tower with 13 hours of thermal energy storage, enabling round-the-clock clean electricity generation. The project represents a significant technical achievement and demonstrates the viability of baseload renewable energy in Saudi Arabia’s climate.

KAUST researchers are conducting advanced CSP research, including the development of novel heat transfer fluids that can operate at higher temperatures and increase power generation efficiency. The university’s solar village serves as a testbed for experimental CSP technologies, including particle-based systems that replace liquid heat transfer fluids with solid particles capable of withstanding temperatures above 1,000 degrees Celsius.

Solar Panel Manufacturing

Saudi Arabia is not content to merely deploy solar technology; it aims to manufacture it. The Kingdom is building a domestic solar panel manufacturing industry that will reduce dependence on imported panels, create high-value manufacturing jobs, and potentially position Saudi Arabia as a solar equipment exporter.

The PIF has invested in solar manufacturing through several channels. A joint venture with Chinese solar manufacturer Longi has established a solar cell and module manufacturing facility in NEOM, with initial production capacity of 5 gigawatts per year. The facility produces monocrystalline PERC and TOPCon solar cells, representing current generation technology with pathways to next-generation cell architectures.

The Saudi Arabian Mining Company (Ma’aden) is developing polysilicon production capability, targeting the production of the ultra-pure silicon used in solar cell manufacturing. Saudi Arabia’s abundant quartz resources and low-cost energy provide potential competitive advantages in polysilicon production, one of the most energy-intensive steps in the solar manufacturing value chain.

Research into next-generation solar technologies is being conducted at Saudi universities and research institutions. KAUST’s Solar Center is a global leader in perovskite solar cell research, developing lightweight, flexible solar cells that could be manufactured at lower cost than conventional silicon cells. While perovskite technology has not yet reached commercial scale, KAUST’s research has produced record-breaking cell efficiencies and advanced the understanding of perovskite stability and degradation.

Green Hydrogen

Green hydrogen, produced by splitting water using renewable electricity, has emerged as Saudi Arabia’s most strategically significant clean energy technology. The Kingdom’s combination of cheap renewable energy, available land, existing export infrastructure, and geographic proximity to major energy-importing markets gives it formidable advantages in the emerging global hydrogen economy.

NEOM Green Hydrogen Project

The NEOM Green Hydrogen Company, a joint venture between NEOM, ACWA Power, and Air Products, is building the world’s largest green hydrogen production facility. Located in the Oxagon industrial zone, the project will produce 600 tons of hydrogen per day, equivalent to approximately 1.2 million tons of green ammonia per year, which will serve as the hydrogen carrier for export.

The project’s scale is extraordinary. It will be powered by 4 gigawatts of dedicated renewable energy capacity, including both solar PV and wind turbines. The electrolyzer capacity of 2.2 gigawatts will use thyssenkrupp nucera’s alkaline water electrolysis technology. The green ammonia produced will be exported through a dedicated port facility at NEOM, with Air Products managing global distribution.

Commercial production is expected to begin in 2026, making it one of the first large-scale green hydrogen projects to reach commercial operation anywhere in the world. The project’s economic viability is underpinned by the extremely low cost of renewable electricity in Saudi Arabia and the long-term offtake agreement with Air Products, which has committed to purchasing the entire output for distribution to global customers.

Hydrogen Strategy

Saudi Arabia’s hydrogen strategy extends well beyond the NEOM project. The Kingdom has identified hydrogen as a pillar of its future energy export portfolio, with the goal of capturing 10 percent of the global hydrogen market by 2030.

Additional green hydrogen projects are in various stages of development across the Kingdom. ACWA Power is developing several large-scale hydrogen projects linked to new renewable energy installations. Saudi Aramco, while also pursuing blue hydrogen produced from natural gas with carbon capture, has announced plans for green hydrogen production capacity linked to its existing industrial and export infrastructure.

The Kingdom’s hydrogen strategy addresses not only production but the entire value chain, including storage, transport, and end-use applications. Research into advanced storage solutions, including metal hydrides, liquid organic hydrogen carriers, and underground geological storage, is being conducted at Saudi universities and research centers. The conversion of hydrogen to ammonia for transport, and the subsequent reconversion to hydrogen at the destination, is being optimized through both process improvements and novel catalyst development.

Hydrogen Export Infrastructure

Saudi Arabia’s existing energy export infrastructure provides a significant advantage in the hydrogen economy. The Kingdom’s ports, particularly those on the Red Sea and Arabian Gulf coasts, are well-positioned to serve major hydrogen-importing markets in Europe, East Asia, and South Asia. Existing pipeline infrastructure, originally built for oil and gas, may be adaptable for hydrogen transport in some cases.

The King Salman Global Maritime Industries Complex at Ras Al Khair is expanding its capabilities to support hydrogen and ammonia export vessels. The facility’s deep-water port, combined with adjacent industrial zones suitable for hydrogen production and conversion, creates an integrated export hub for clean energy products.

Battery Storage

Battery energy storage systems (BESS) are critical to Saudi Arabia’s renewable energy strategy, providing the flexibility and reliability needed to integrate variable solar and wind generation into the electricity grid. The Kingdom is deploying battery storage at multiple scales, from utility-scale installations that stabilize the national grid to distributed systems that support industrial and commercial operations.

Grid-Scale Storage

The Saudi Electricity Company (SEC) has begun deploying grid-scale battery storage systems to manage the variability of renewable energy generation and provide grid services including frequency regulation, voltage support, and peak demand management.

The first major grid-scale battery project, a 1,200-megawatt-hour lithium-ion system near Tabuk, was commissioned in 2025. The system stores excess solar energy generated during midday hours and dispatches it during the evening demand peak, reducing the need for natural gas-fired power plants to ramp up after sunset. Additional grid-scale battery projects totaling more than 5 gigawatt-hours of capacity are planned for deployment by 2030.

The choice of battery technology for these installations reflects both current market conditions and Saudi Arabia’s long-term strategic interests. Lithium-ion batteries dominate current deployments due to their maturity, declining costs, and established supply chains. However, Saudi Arabia is actively evaluating alternative technologies including sodium-ion batteries, iron-air batteries, and flow batteries that may offer advantages in cost, duration, or sustainability for future deployments.

Battery Manufacturing

Saudi Arabia has identified battery manufacturing as a strategic industry, with the potential to serve both domestic demand and export markets. The PIF has made investments in battery technology companies and announced plans for a battery manufacturing facility in the Kingdom.

The facility, expected to begin production in 2028, will initially manufacture lithium-ion batteries using cells produced domestically and sourced from international suppliers. The long-term vision includes the development of a complete battery supply chain within the Kingdom, from raw material processing to cell manufacturing, pack assembly, and recycling.

Saudi Arabia’s mineral resources support this ambition. The Kingdom has identified deposits of lithium, cobalt, nickel, and other battery materials in its western and central regions. The Saudi Geological Survey has conducted extensive mapping of these resources, and Ma’aden is evaluating the feasibility of mining operations that could supply a domestic battery manufacturing industry.

Research and Development

Saudi researchers are contributing to the advancement of battery technology through both fundamental research and applied development. KAUST’s battery research program is focused on solid-state batteries, which promise higher energy density and improved safety compared to conventional lithium-ion batteries. The university has achieved several notable breakthroughs in solid-state electrolyte materials and interface engineering.

King Fahd University of Petroleum and Minerals (KFUPM) has established a battery testing and characterization center that serves both academic researchers and industry partners. The center’s capabilities include accelerated aging tests that simulate years of battery operation in weeks, providing data crucial for predicting battery performance in Saudi Arabia’s extreme heat conditions.

Carbon Capture, Utilization, and Storage

Carbon capture, utilization, and storage (CCUS) technology occupies a unique position in Saudi Arabia’s clean energy strategy. While environmental advocates often view CCUS as a means of prolonging fossil fuel dependence, Saudi Arabia sees it as a pragmatic tool for reducing emissions from industries that cannot easily electrify, and as a bridge technology during the transition to a fully renewable energy system.

Uthmaniyah CO2-EOR Project

Saudi Aramco’s Uthmaniyah CO2 Enhanced Oil Recovery (EOR) demonstration project, operational since 2015, captures carbon dioxide from gas processing facilities and injects it into oil reservoirs to both store the CO2 and enhance oil recovery. The project captures approximately 800,000 tons of CO2 annually, making it one of the largest CCUS operations in the Middle East.

The captured CO2 is compressed, transported via pipeline, and injected into a depleted section of the Ghawar oil field, the world’s largest. The injection enhances oil recovery by increasing reservoir pressure and reducing oil viscosity, potentially extending the productive life of the field while permanently storing CO2 underground.

Jubail Carbon Capture Hub

Saudi Arabia is developing a major carbon capture hub in Jubail, the Kingdom’s primary industrial city. The hub will aggregate CO2 from multiple industrial sources, including petrochemical plants, steel mills, and cement factories, for transport and geological storage.

The Jubail hub’s first phase, targeting capture of 9 million tons of CO2 per year, is under development with participation from Saudi Aramco, SABIC, and several international partners. The captured CO2 will be transported via a network of pipelines to geological storage sites in depleted oil and gas reservoirs and deep saline formations.

The hub approach offers significant advantages over facility-by-facility carbon capture. Shared transport and storage infrastructure reduces per-ton costs. Aggregating CO2 from multiple sources creates economies of scale in compression and injection operations. And the hub model provides a framework for adding new capture facilities as industrial processes are retrofitted or new plants are built.

Direct Air Capture

Saudi Arabia has begun exploring direct air capture (DAC) technology, which removes CO2 directly from the atmosphere rather than capturing it at the point of emission. While DAC is currently more expensive than point-source capture, the technology has the potential to achieve negative emissions, actually reducing atmospheric CO2 concentrations, which may be necessary to meet global climate goals.

KAUST is conducting research on DAC materials and processes optimized for Saudi Arabia’s hot, arid climate. The university’s researchers have developed novel sorbent materials that capture CO2 from ambient air and release it when heated, using solar thermal energy as the heat source. This approach leverages Saudi Arabia’s abundant solar resources to power a process that could, at scale, transform the Kingdom from a major source of CO2 emissions to a significant carbon sink.

CO2 Utilization

Beyond storage, Saudi Arabia is investing in technologies that convert captured CO2 into valuable products. SABIC, one of the world’s largest petrochemical companies, has developed processes that use CO2 as a feedstock for producing chemicals, plastics, and building materials.

Saudi Aramco’s carbon utilization research program is exploring the conversion of CO2 into synthetic fuels, which could serve as carbon-neutral alternatives to conventional aviation fuel and shipping fuel. While these processes are energy-intensive, using renewable electricity to power them creates a pathway to truly carbon-neutral transportation fuels.

Integration and System Optimization

The individual renewable energy technologies deployed in Saudi Arabia do not operate in isolation. Their full potential is realized only when they are integrated into a coherent energy system that balances generation, storage, and demand.

Smart Grid Technology

The Saudi Electricity Company is implementing smart grid technologies that enable the real-time monitoring, control, and optimization of the electricity network. Advanced metering infrastructure (AMI), distribution automation, and grid analytics platforms provide the visibility and control needed to manage a grid with increasing shares of variable renewable generation.

Demand response programs allow the grid operator to reduce electricity consumption during periods of high demand or low renewable generation by adjusting the operation of flexible loads such as air conditioning systems, water heaters, and industrial processes. These programs, enabled by smart meters and connected devices, reduce the need for peak generation capacity and improve the economic utilization of renewable energy assets.

Energy System Modeling

Saudi Arabia employs sophisticated energy system models to plan the optimal mix of generation, storage, and transmission capacity for the future electricity system. These models consider factors including renewable resource availability by location and time, electricity demand patterns, technology costs, grid constraints, and policy objectives.

The King Abdullah Petroleum Studies and Research Center (KAPSARC) is a global leader in energy system modeling and has contributed significant insights into the optimal pathway for Saudi Arabia’s energy transition. KAPSARC’s analysis has informed government decisions on renewable energy targets, storage requirements, and the role of hydrogen in the future energy mix.

Economic Impact and Industrial Policy

Saudi Arabia’s renewable energy technology investments are generating significant economic activity and creating high-value jobs. The renewable energy sector employed an estimated 25,000 people in Saudi Arabia in 2025, a number expected to grow to more than 100,000 by 2030 as manufacturing capacity expands and new projects come online.

The localization requirements attached to renewable energy projects ensure that a significant share of the economic value remains within the Kingdom. REPDO’s tender requirements mandate minimum local content levels for equipment, engineering, and construction services, creating demand for Saudi suppliers and workers.

The development of renewable energy manufacturing capability, including solar panels, batteries, and hydrogen electrolyzers, represents a strategic bet on the industries of the future. Saudi Arabia’s objective is not simply to consume renewable energy technology but to produce and export it, creating new revenue streams that complement and eventually replace oil income.

The renewable energy technology landscape in Saudi Arabia is a testament to the Kingdom’s capacity for strategic reinvention. The same nation that built the world’s most efficient oil production and export system is now applying the same ambition, resources, and organizational capability to building a clean energy future. The sun that has always defined Saudi Arabia’s landscape is becoming the engine of its next economic transformation, and the technologies being deployed and developed in the Kingdom today will shape the global energy system for decades to come.
