Nuts and Bolts of Hydrogen Production.

Happy couples, happy valley? Sector coupling and valley model as drivers for hydrogen economy

Green hydrogen is still more expensive than the carbon-intensive alternatives. 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?

Green is good! Replacing gray hydrogen in industry

Hydrogen has been used in many industries for a long time. But the hydrogen has been gray; that is produced from fossil fuels. Replacing gray for green hydrogen in industrial uses could reduce carbon emissions greatly - and doing that seems like the lowest hanging fruit for advancing the hydrogen economy. But how low does it actually hang?

Hydrogenie in the bottle? Infrastructure Needs of Hydrogen Economy.

Hydrogen economy needs supporting infrastructure. Hydrogen is a gas. We have transported and stored various gases in pipes and tanks for well over a century. Is hydrogen somehow different to for example natural gas? Can we reuse existing transmission infrastructure? Where should new hydrogen pipes be built and why? How is the electricity grid connected to this decision? And how the electricity grid infrastructure supports the hydrogen economy?

Nuts and Bolts of Hydrogen Production.

We have known how to produce hydrogen for over 100 years - but mostly relying on carbon-intensive production methods. Currently, greener and cleaner hydrogen production is more expensive. To bring the cost down, we need to scale up the production capacity. How is green hydrogen produced? What are the bottlenecks and costly steps? How can we solve them and ramp up production capacity?

Show(el) Me the Money! Hydrogen Regulation, Incentives, and Investments.

Show(el) Me the Money! Hydrogen Regulation, Incentives, and Investments. 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?
