Fatih Birol
Executive Director. As Executive Director of the International Energy Agency, Dr Fatih Birol (@fbirol) has positioned the IEA at the forefront of global efforts to advance a secure, affordable and sustainable energy system. Since taking office in 2015, he has modernised the Agency by broadening its energy security mandate beyond oil to include electricity, natural gas, renewables and critical minerals, strengthened the Agency's global leadership in clean energy transitions and expanded IEA membership to include major emerging countries. As a result, the IEA’s share of global energy demand coverage has increased from 40% to over 80%. He has also played a central role in the global response to major energy security emergencies, including those triggered by the invasion of Ukraine in 2022 and the 2026 Strait of Hormuz crisis.Dr Birol joined the IEA in 1995 and steadily rose through the ranks from junior analyst to Chief Economist, wher...

Sodium-ion battery momentum grows, but challenges remain
…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 appearing in Japan in 1996 – sodium-ion batteries reached vehicle applications much later, with the first sodium-ion powered electric car introduced in China only in late 2023. The first battery storage system using sodium-ion batteries was installed a few years earlier, in 2019 in China. However, in 2025…
