The problem of renewable and environmentally sustainable energy is affecting the whole planet and it is good to be aware of it and roll up our sleeves in an attempt to solve it. In this regard it is now understood that hydrogen is one of the cleanest forms of energy and it would be desirable for our future to be in that direction. Unfortunately it is not easy to get a fuel like that because it is not in its natural state in this form and so far the methods of production have proved to be expensive. But a group of researchers from the Universities of Antwerp and the University of Leuven invented a small device that is able to derive hydrogen from the purification process
This device therefore responds to two requirements simultaneously: it allows to develop an alternative form of energy and purifies the polluted air. But how does it work? To answer, we use the words of Professor Sammy Verbruggen from the department of bioengineering at the University of Antwerp who said: "We use a small device with two chambers separated by a membrane, on the one hand the air is purified while on the other hydrogen obtained from degradation products This hydrogen can be stored and stored to be used as fuel, as has already been done for some hydrogen buses ".
Some particular nanomaterials are used on the membrane, where most of the process takes place; this mechanism is based on a process used to extract hydrogen from water which has now been converted into this second version which seems to be even more efficient than the first. Precisely for this reason we thought to experiment with the device in industries that produce large amounts of air pollution, but to realize this idea will take another time because the device is currently only a small-scale prototype. We will therefore have to wait before discovering whether we will be able to make progress towards the pollution problem.
