While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.

Interest in energy storage in the Middle East is ‘ramping up significantly’, as we reported last week in an extract from this interview with IHS Markit analyst Julian Jansen. His firm is forecasting 1.8GW of energy storage for the region by 2025 – from an installed base of next-to-nothing today. Jansen talked us through some of the drivers, market dynamics and the general picture of what we might see developing.
