So called sector couplings or sector integrations are an important way to combat this.

These come in varied shapes and sizes. Common to them is that they are best realised when they are also geographically close or even co-located.

This is why we also talk about hydrogen valleys.

But what are the valleys? And the sector couplings? What is needed to form them?

In addition to being a key part of the green energy transition, the hydrogen economy has been hyped up as a potential gold mine and creator of jobs by industry pundits and governments alike.

But investments have been slower and smaller than initially anticipated. Stories about the death of the hydrogen hype have been piling up in the media lately. Why is this? Is the hydrogen economy takeoff really stalling? And what roles regulation, incentives and investments play in all this?
