Hydrogen Valley Podcast

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...

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? Episode Guests: Mikko Rönkä, Asset Transformation Manager,...

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 gri...

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? Episode guest...

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...

Firms, the EU and national governments are now investing and betting large sums of money on green hydrogen. It is seen as a big component in our urgently needed transition to greener forms of energy to fight climate change. But hydrogen has been used in industry for over a hundred years. Why are we pinning our hopes on green hydrogen now? Is the hype warranted? What’s different now? Episode guests...

Hydrogen is expected to be a key part of our green energy transition. But we have used hydrogen for over 100 years. Why is there hype around hydrogen now? Are the hopes warranted? What is required to make the hydrogen economy a reality? In the soon to be published Hydrogen Valley Podcast, Mikko Heiskala, a visiting researcher at the Department of Industrial Engineering at Aalto University intervie...
