Solar and wind now supply a fast-growing share of the world's electricity, but both disappear when the sun sets or the wind drops. That mismatch between when energy is generated and when it is needed is arguably the single biggest obstacle to a fully renewable grid — and closing it is exactly what advanced energy storage technologies are built to do, whether through batteries, hydrogen, thermal systems or mechanical solutions.

This course from the Arab British Fellowship Training Academy takes participants deep into how these storage technologies actually work, where each one fits best, and how they are already being deployed to stabilise grids, cut costs and support the shift to a low-carbon energy system.
