One alternative to batteries for electric motorcycles is the hydrogen fuel cell, where a tank of hydrogen is converted into electricity to power an electric motor with zero emissions.
The advantage over a battery is the speed of refuelling, meaning longer rides could be quicker and would benefit touring riders.
But it’s challenge. First, hydrogen is the smallest molecule which means it will escape via the tiniest blemish in any tank, pipe or connection. So filling up will need better system than just putting a nozzle into an open tank cap.
Second, fuel cells tend to be bulky, which makes packaging the whole thing difficult and create a usable machine.
However, given that fuel cells have zero emissions – the hydrogen becomes water during the fuel cell process – some people believe there’s an opportunity.
To find out a consortium of German and Czech research institutions and manufacturing companies are taking on the challenge. Their aim, by the end of 2025, is to construct a fully functional motorcycle as a demonstrator that complies with strict European standards.
It’s called the Hydrocycle Project. Czech partners are working on vehicle development, advancing work packages related to vehicle structure, ergonomics, and packaging (fitting the technology into the available space).
German project partners are focusing on the powertrain. WätaS Wärmetauscher Sachsen GmbH is developing a new generation of fuel cell stacks as the basis for the powertrain.
The whole project is being supported by Fraunhofer Institute for Machine Tools and Forming Technology – better known as IWU – which will ensure a smooth interface between vehicle and fuel cell system development.
