Just heat
If the Village’s first solutions were adopted, we would use the sun… But not to produce electricity. With its concentrated solar power plants – basically, fields of mirrors – Alto solution produces heat, between 100 and 400°C, to heat all types of fluids. And this energy can be stored. In Vaucluse, Le Coq noir, a food industry manufacturer, is testing this solution to reduce its dependence on natural gas by 75%.
With the sun and Heliosand lenses, we can even reach more than 2,000°C. This young company’s technology can transform quarry sludge into obsidian, a volcanic rock used in the manufacture of glass wool. If the sludge contains less silica, this produces aggregate that can be used for construction.
So many solutions!
The Decarbonization Village favored developers of technical solutions over design firms. If some are present, it is because they are proposing an innovation that meets the challenges. Carbone 350, for example, has found a way to make the restoration of peatlands profitable, thus hoping to prevent these natural carbon sinks from turning into timed climate bombs.
Inventiveness and disruption are therefore the key words of this Decarbonization Village to be discovered on Wednesday February 5 and Thursday February 6 at Alpexpo, in Grenoble.
