We had tried them in early 2019 in Vannes, they were put forward at the G7 of Biarritz this summer: Pragma hydrogen bikes were indeed attraction, in a city prohibited for traffic for a weekend weekend . These bikes made by a city company are already present in Cherbourg, Chambéry, Bayonne and of course Biarritz. For the founder of Pragma, Pierre Forté, if hydrogen is suitable for heavy vehicles, it is also in bikes, especially those in self-service. For these parks (self-service bikes), energy and recharges represent two thirds of operational costs. More autonomous than an electric bike, quickly rechargeable, hydrogen bikes may well have their place in these two-wheeled fleets. It provides for the sale of 25,000 bikes by 2024, a quantity that would save a scale for two-wheelers that cost several thousand euros today.
The English company ISS Aerospace has developed “ENSUS”, a drone powered by a fuel cell. Being able to receive many sensors, it is specially designed to carry out environmental analyzes, in particular the detection of air quality in which it can identify more than 70 chemicals and model atmospheric pollution in 3D. It could thus prove to be very useful to guide, for example, the public authorities in the event of factory fire classified Seveso.
