Electricity 2026 Reliability
Largescale outages amid system instability, equipment failures and weather impacts As the Age of Electricity evolves, with steadily rising electrification rates and electricity demand, blackouts can impact a vast part of economies and social life. Outages induced by operational failures, technical error, or climate-driven events illustrate the importance of redundancy, resilience, and thorough oversight. The following list of outage incidents in 2025 underscores how ensuring the security, reliability and resilience of power systems is evolving from a technical challenge to a strategic necessity that requires unwavering attention from system operators, regulators, and policy leaders. Voltage management increasingly important for…

Global Energy Review 2026 Technology: Battery storage
Battery storage is the fastest growing power technology today. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024. Installed capacity is now eleven times higher than in 2021. Lithium‑iron phosphate (LFP) batteries now account for around 90% of deployments; while less energy‑dense than rival chemistries commonly used in EVs, LFP batteries are typically cheaper and better suited to more frequent cycling. Just five years ago, the market share of LFP batteries in deployments was well below 50%. Around 80% of new battery capacity in 2025 was utility‑scale. The remainder was behind-the…

Global Hydrogen Review 2026 Production
Global hydrogen production remains dominated by unabated fossil fuels. Low-emissions hydrogen production reached almost 1 Mt in 2025 and is expected to register record growth in 2026, accounting for more than 1% of global production, strongly concentrated in China, Europe and North America.Installed electrolysis capacity doubled in 2025 to surpass 4 GW, thanks to the commissioning of several large-scale projects in China. More than 2.5 GW are under construction, targeting operation in 2026. Growth is expected mostly in Europe, with 2 GW, but is highly concentrated in a small number of big projects.One large project for production from fossil…

Oil 2025 Executive summary
Turbulent times in oil markets Heightened geopolitical risks, unresolved trade tensions, and policy shifts have added myriad uncertainties to the oil market outlook. Since the start of the year, major economic forecasters have cut their outlooks for world GDP growth in 2025 by roughly half a percentage point to around 2.8% and see a below-trend pace of about 3% annually for the remainder of the decade, with knock-on implications for oil demand. With conflicts in the Middle East region at risk of intensifying and trade negotiations ongoing, uncertainties surrounding our forecasts are substantial. At the same time…
