Project Description

Green hydrogen prodution for energetic self sufficiency in areas that are far away from the grid.

Application

The hydrogen produced is used to store solar energy, coupled with lithium batteries, to supply a geothermal power plant in Cerro Pabellón, when solar radiation is low. This provides energy for 600 workers from the plant.

Energy storage system (ESS) of hydrogen able to provide 450 kWh, coupled with a 132 kWh lithium battery system.
