In Br\u00fctten near Zurich in Switzerland, an apartment building with nine rental flats that is not connected to the energy grid has now been inaugurated.<\/p>\n
\"The rental costs are no higher than elsewhere. The most important energy source is photovoltaic modules. Schmid had an electrolyser installed in the cellar as a long-term storage unit for the solar power. The device uses solar electricity to produce hydrogen from water, which is stored in tanks. From the hydrogen, a fuel cell generates electricity and heat when the sun is not shining.\"<\/p><\/blockquote>\n
\nThe cars for the tenants are also largely supplied by the system.<\/p>\n
