    •Clean hydrogen with maximum 4.90 kgCO2e/kgH2 GHG emission from the production process
    •Renewable hydrogen with maximum 4.90 kgCO2e/kgH2 GHG emission from the production process, while using renewable energy (wind energy, solar energy, hydro power etc.) produce hydrogen
There are many types of hydrogen pro
