Designing an effective strategic stockpiling system for critical minerals
critical minerals 2025 was the year when the risks of highly concentrated critical minerals supply chains materialised at scale The IEA has long warned of the potential security risks associated with the high concentration of critical mineral supply chains. In 2025, these risks became a reality, marking a major turning point for global economic security. The rare earths export controls announced by China in October 2025 posed major national and economic security risks across the world, with potentially severe impacts for a range of strategic sectors including energy, automotive, defence, aerospace, AI and semiconductors. Earlier export controls introduced in April…

How global oil supplies have readjusted to help fill the huge gap left by the Strait of Hormuz shock
commentary Stock drawdowns, alternative routes and suppliers, and agile refiners have all contributed during the crisis, avoiding far more severe impacts on demand Global energy markets have been contending with their largest supply disruption in history resulting from the near closure of the Strait of Hormuz, a vital artery for oil and gas shipments to reach global markets. The cumulative oil supply losses from producers in the Middle East now exceed 1.3 billion barrels, with flows through the Strait of Hormuz falling from around 20 million barrels per day prior to the conflict to an average of 2.7…

Wired for water: How electrification is transforming desalination
…water-energy nexus Pressure on water resources is increasing worldwide and can be very acute at the local level. Rising consumption across sectors combined with population growth in already water-stressed regions is intensifying water scarcity. Desalination has long been developed to supply fresh water in the most affected areas, with significant implications for the energy system: energy use ranges from under 0.1% to as much as 15% of total final consumption, depending on national reliance. However, a shift is underway from thermal desalination technologies to electricity-driven systems as the Age of Electricity reshapes the water-energy nexus…

Investment in next-generation geothermal is surging. Policies are key to further growth
…These technologies are advancing quickly, potentially enabling economically-viable geothermal development nearly anywhere in the world. The IEA’s Future of Geothermal Energy report, published in late 2024, estimated that with continued technology improvements and reductions in project costs, next-generation geothermal could meet up to 15% of global electricity demand growth to 2050. Geothermal technology families Next-generation geothermal technology remains at an early stage of development. In general, geothermal projects remain among the most capital-intensive in the energy sector, with drilling and well costs often representing up to 80% of total costs. Yet the past year has…

Battery storage is scaling up and taking on a larger system role
Commentary As the result of falling costs and greater flexibility needs, battery storage is playing a growing role in power systems worldwide, acting as a “multi-tool” that can provide a range of critical system services at once. According to the latest data, the deployment of batteries expanded strongly in 2025 and broadened across markets – with rapid growth in countries such as Australia and Saudi Arabia, where storage is increasingly being used to support the integration of rising shares of variable renewables.In regions that have been at the forefront of renewable integration and battery deployment, batteries now play an…

Global battery markets are growing strongly – and so are the supply risks
…power systems, and an increasingly important source of back-up power for digital infrastructure, including data centres and artificial intelligence.Beyond energy, batteries remain indispensable for a wide range of industrial and strategic applications, from portable electronics and unmanned defence systems to emerging technologies such as humanoid robots. As applications diversify and costs continue to fall, batteries are evolving into a foundational component of modern economies. This shift carries far-reaching implications for economic competitiveness, supply security and industrial policy, as battery supply chains remain highly concentrated and technologically complex.These dynamics are already evident in battery deployment trends, as…

Canada is set to play a leading role in supplying the world with responsibly produced critical minerals
…conducting Critical Mineral Reviews – in-depth country reviews of critical mineral policies and security that have served as part of the Agency’s pioneering work to ensure secure mineral supply chains. The latest Critical Minerals Review of Canada shows that at a time of increasing concentration risks, including from export controls by the dominant supplier, Canada has the potential to contribute to the development of secure, diversified and competitive global supply chains for critical minerals.Canada can serve as a major supplier of key critical minerals. It has abundant reserves of many of the critical minerals necessary for energy technologies…

Policy and financing momentum sustain CCUS progress despite setbacks
CCUS Projects Database 2026 commentary Efforts to expand carbon capture, utilisation and storage (CCUS) took some important steps forward in 2025. Despite delays and cancellations in some areas, projects reached notable milestones in key markets, while growing financing provided further momentum.CCUS deployment in Europe saw a step-change as the world’s first dedicated carbon dioxide CO2 storage hub began operating in Norway. Major projects were also commissioned in China and North America, and the construction of new facilities began in eight countries worldwide. The newest annual update to the IEA’s CCUS Project Database – which incorporates developments between…

Sodium-ion battery momentum grows, but challenges remain
batteries commentary sodium batteries Recent technological advances and investment announcements suggest dynamics are shifting for sodium-ion batteries Sodium-ion batteries are emerging as a new player in battery markets, offering opportunities to diversify battery chemistries and supply chains at a time of rising global demand for electric vehicles and energy storage. Developed in laboratories since the early 1980s, sodium-ion batteries operate on the same fundamental principles as lithium‑ion batteries – which currently dominate the market – yet their path to commercialisation has been markedly slower.While lithium-ion batteries entered commercial use in the 1990s – with the first electric vehicles…

Copper prices have hit record highs, but smelters face mounting strategic pressures
…copper market – strong structural demand growth and elevated prices – may be good news for producers. However, today’s situation is unusual in that the crucial midstream sector is showing increasing signs of stress, amid a surge in smelter capacity additions in China. Copper is set to face a major supply deficit of 30% by 2035 Copper – a highly conductive metal that is resistant to corrosion – is at the heart of a more electrified energy system. As the world enters an Age of Electricity, strong demand growth for copper is anticipated from a wide variety of sources, including grids, electric vehicles…
