Hydrogen is difficult to store and transport, with large volumes and high pressures and flammability involved. Students of the Technical University of Eindhoven are trying a new approche to hydrogen storage:
The system works as follows; the energy of hydrogen is stored via a reaction with iron oxide (also known as rust), producing iron and water. In the process, the iron serves as a storage medium that can be easily transported. Then, to provide hydrogen, iron must be brought into contact with steam, after which hydrogen and iron oxide remain. This creates a cycle in which iron acts as a kind of sustainable ‘hydrogen battery’, with the note that it is not hydrogen but iron that is stored and transported.
Thanks to iron, volumetric energy density of stored hydrogen, absorbed into iron pellets, can be increased by a factor of 3, at convenient ambient pressure.

Go vertical!
Spoiler: vertical panels have a much higher heat transfer coefficient and hence lower operating temperatures.

Have we been doing Solar wrong all along? Solar panels facing up towards the sky, which makes sense. You want a wider area to catch more of that sweet solar energy, right? However, bifacial vertical solar panels have started to gain traction recently. Their more flexible-footprint has innovators in Canada, Norway and elsewhere testing them in all kinds of weird scenarios. People who are using these panels are reporting something odd – higher energy yield than expected. The extra yield stumped engineers, but a recent Dutch study may shed some light on the source of this extra energy. Have we been doing solar panels wrong this whole time, or is it all just a miscalculation? And how could this tech impact our lives?

Electric vehicles are taking the world by storm, sparking conversations and controversies alike. Are they the green champions of the road or hidden culprits of environmental harm? Can they truly replace the roar of petrol engines without missing a beat? And is our infrastructure ready to support this electric revolution, or will it buckle under the pressure?
In this video, we’re plugging into the heart of these debates.
We’ll explore what happens when innovation meets the open road, and whether the journey towards electric mobility is as smooth as the ride in an EV itself. Join me as we navigate through the electric landscape, separating fact from fiction with solid evidence and expert insights. It’s time to discover the real story behind electric vehicles. Let’s roll out!Bookmarks:
