Based on the 'Progetto Idrogeno per Arezzo' - the first world wide underground low pressure 1km hydrogen pipeline - we test a complete zero emission sun-hydrogen-power-cooling cycle. A photovoltaic roof on the Arezzo's HydroLAb is providing electricity to a high efficiency membrane electrolyzer. Water is then converted into hydrogen to be stored in a metal hydride tank or sent to pipeline. Hydrogen is then used back in 5kWe fuel-cells whose cooling system provides 4.5kWth of heat. This heat, integrated by a solar thermal system with vacuum tubes, is used in an lithium bromide absorption chiller for HydroLAb cooling with low electric consumption. Heat or chill are diffuse by mean of fan coil or plaster radiant walls inside the HydroLAb.

Abstract
Based on the 'Progetto Idrogeno per Arezzo' - the first world wide underground low pressure 1km hydrogen pipeline - we test a complete zero emission sun-hydrogen-power-cooling cycle. A photovoltaic roof on the Arezzo's HydroLAb is providing electricity to a high efficiency membrane electrolyzer. Water is then converted into hydrogen to be stored in a metal hydride tank or sent to pipeline. Hydrogen is then used back in 5kWe fuel-cells whose cooling system provides 4.5kWth of heat. This heat, integrated by a solar thermal system with vacuum tubes, is used in an lithium bromide absorption chiller for HydroLAb cooling with low electric consumption. Heat or chill are diffuse by mean of fan coil or plaster radiant walls inside the HydroLAb.
