The problem with batteries is that you can’t keep them indefinitely because they suffer from degradation. The same does not happen with hydrogen, which can be stored until we want to use it. Under this idea, the Japanese startup Scitem is going to start sell the first hydrogen-based portable generators.
Starting this spring, it will be possible to purchase small power generators, the size of a briefcase. Inside there will be interchangeable hydrogen cartridges. A kind of mini hydrogen cylinders that allow to produce electricity.
A hydrogen case to charge the PC or the electric bicycle
The idea of these portable generators is to be able to have access to energy when we need it, with the addition that the system does not emit CO2 and does not degrade over time as it happens with lithium batteries.
As Nikkei describes, the system works with small cylinders that are easily interchangeable and that allow to generate up to 30 W of power, enough to be able to charge a laptop or even a small vehicle, such as an electric bicycle.
The generator allows you to recharge devices through a traditional plug or USB cable. But the most innovative thing is that they have managed to create a system around hydrogen and at a relatively affordable cost. Scitem raises a cost of 500,000 yen, about 3,800 euros to change.
This cost is for the 30W version, but the company is already thinking of other generators with different power levels. To date the company sold hydrogen generators for business and research, but this is the first step with a commercial aspect facing the user on foot.
Scitem’s solution has no motor, no vibrations and no carbon dioxide emissions. Hydrogen is a cheap and affordable energy source, but its biggest challenge is transporting and managing it. That is precisely why this small energy case is such an interesting solution. We will see to what extent they can offer it at the price they promise and to what extent they can mass produce them.
