The Sustainable Report website published a column on Green Hydrogen by Professor Rodrigo Palma, one of the leaders of the research topic on Energy Storage.
Palma raises there:
“H2 is called green when its generation does not emit carbon dioxide. For this, a clean energy source is required, which allows the delivery of electrical energy to an electrolyser, a device that is capable of separating the water molecule into hydrogen and oxygen. In fact, to generate one kg of H2, around 50 kWh of electrical energy and 9 liters of water are required.
From here arises the first great opportunity for Chile, given our immense potential for low-cost renewable energy (solar, wind, etc.). To have a reference, the country’s solar potential exceeds 1,800 GW, while today there is a total generation capacity with all technologies of only 25 GW (72 times!)”
