Hychico was established in 2006 and its main activities, located in Argentine Patagonia, are power generation from renewable sources and the production of hydrogen and oxygen. The Pilot Project, composed of an Hydrogen Plant and a Wind Park, is currently producing High Purity Hydrogen (120 Nm3/h and 99,998 % purity), and the Wind Park is selling the energy through the National Wholesale Electric Market through the national grid. Our current challenge is to test the storage of hydrogen in depleted gas reservoirs as a peaking facility to fuel a turbine or gensets also with natural gas and to study possible methanation processes in the well.
