Podcast Overview

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 Hydrogen Valley Podcast, Mikko Heiskala, a visiting researcher at the Department of Industrial Engineering at Aalto University interviews researchers and industry experts from the BalticSeaH2 Hydrogen Valley, the European H2 Valley of the Year 2025 to understand what the hydrogen economy is about, its components, and what is needed to make it a reality.

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?
