Hydrogen (H 2) produced from renewables will have a growing impact on the global energy dynamics towards sustainable and carbon-neutral standards.The share of green H 2 is still too low to meet the net-zero target, while the demand for high-quality hydrogen continues to rise. These factors amplify the need for economically viable H 2 generation technologies.
Hydrogen is a versatile energy carrier (not an energy source). It can be produced from multiple feedstocks and can be used across virtually any application (see Figure 1).

But as energy demand in Central Europe is high, renewable energy resources are of moderate quality, and available potentials are limited, energy imports from areas with beneficial renewable resources – such as North Africa – might be a promising
Renewable hydrogen is created by using electricity to split water into hydrogen and oxygen through a process known as electrolysis. The hydrogen is collected and used, primarily in industry, while oxygen is released as the by-product or captured for use by others. As we use electricity created from renewables, the process is carbon-neutral.
