Through the years the environment has been polluted due to the excessive and persistent combustion of fossil fuels as source of energy. As a result, the reduction of the carbon dioxide (CO2) footprint is a significant challenge for society and industry, demanding alternatives to a life based on fossil resources now and in the following decades. In particular, the decarbonization of the energy and transport sector as main contributors to CO2 emissions has to be targeted. In this context hydrogen (H2) becomes increasingly important to fight climate change.
When using renewable energy, hydrogen can be generated through water electrolysis in a CO2-free way.
