He was inaugurated last Wednesday, the first idrogenodotto underground for urban areas of the world: the presence of the President of the Region Tuscany, goldsmith in the industrial area of San Zeno around Arezzo were opened the taps to businesses and homes in the area that could use the ‘Hydrogen produced locally through photovoltaics.

A project co-financed by private institutions and local policies: Region Tuscany, City and County of Arezzo, Group Sapio, Exergy Fuel Cells and Cooperativa del Sol have signed the agreement four years ago, investing about one million euros. Today showed that the widespread diffusion of hydrogen, although it has cost more than other renewables (see the ‘wind and photovoltaics) is still strongly supported by Jeremy Rifkin precisely because it can be produced virtually anywhere.

The idrogenodotto is a meter and twenty centimeters wide and traporta pure hydrogen to 42 companies and all’HydroLab, the laboratory demonstration devoted to renewable energies, where they were placed two fuel cells from 1Kw and with a photovoltaic system for production of renewable hydrogen from water through electrolysis.

In a few weeks will start the domestic supply which will cut the cost of road transport and storage and above all, will make common Arezzo energy-independent local production of energy and heat will be sufficient to withstand the industrial consumption is domestic with the added advantage of decoupling these areas from oil and gas. Sustainable economic growth therefore, is sganciabile policies of oil lobbies.
