Hydrogen Market Databook 2025: Introduction

In the first of our series of excerpts from the 2025 Hydrogen Market Databook, we look at how green and blue hydrogen will drive the energy transition, despite significant differences in forecasts for future demand

The world is engaged in an energy transition, one that aims to reduce carbon emissions in not only various industries, but also entire economies. At the time of publication, more than 140 countries have announced net-zero targets, covering approximately 88% of global emissions. Countries and companies are seeking various pathways to limit emissions in industrial operations, transport, power and other various industries. One of these routes is through low-/zero-carbon hydrogen. Undoubtedly, low-/zero-carbon H₂—referred to as blue or green hydrogen—will play a major role in decarbonisation efforts globally. The colour of hydrogen is determined by the pathway of production. Green hydrogen is pr
