Just as the process requires electricity, the nuclear is delighted to sell its production.

when using solar energy, the efficiency is less important because there is no meter on the sun! photosynthesis does not have a big yield but has a great advantage: it works alone without inventing anything!
Belgians recycle fuel pollution
A team of scientists from the University of Antwerp and the University of Leuven (KUL) have developed a small device that cleans the air. But in addition, it turns this pollution into fuel: hydrogen.
Removing the stale air of our cities is a challenge that many scientists face. But if in addition, we can recycle the pollution into something useful, it's all bonus. A Belgian team (University of Antwerp and University of Leuven) has managed this challenge. They imagined a device transforming the pollution of the air into hydrogen. The H2 can then be used as fuel for fuel cell cars. What a stone 2 shots by counterbalancing carbon emissions.
Technology
Belgian researchers have developed their device using "heterogeneous photocatalysis" as well as nanomaterials and a photoelectrochemical cell. Behind all this jargon lies a process that transforms polluted air into hydrogen through a catalyst and sunlight. The small apparatus has two chambers separated by a membrane. In the 1re, the air is purified with a photoanode. In the 2de, a cathode behind the solid electrolyte membrane degrades the residues to extract the hydrogen, much like the electrolysis of water.
Not for now
Its use is simple: just place it in the light and provide a means of recovery and storage of the H2. This hydrogen can then feed the FCEV cars. At present, the Belgian researchers have just made a small device of a few square centimeters. So difficult to clean up a city with such equipment. Nevertheless, Belgian researchers around Prof. Sammy Verbruggen have succeeded in demonstrating its feasibility. It only remains to improve the process before possibly studying its industrialization. Which is certainly not for now
