Strategies for the expansion of infrastructures
Hydrogen can achieve a significant reduction of CO₂ emissions in the very short term. If 20 percent hydrogen were added to our natural gas – which is already possible in principle today – greenhouse gas emissions could already be reduced by around 7 percent per year. A significant and at the same time rapidly effective contribution to climate protection. Policymakers are therefore pushing ahead with the development of infrastructures for the production, distribution and use of the new energy source hydrogen. At the beginning of July 2020, for example, the EU Commission presented a hydrogen strategy that envisages a major expansion of generation capacities. The German government also published its National Hydrogen Strategy this summer. In it, funding totaling 9 billion euros is envisaged for the targeted further development of a hydrogen infrastructure.
Green hydrogen – what's behind it?
Hydrogen does not exist on earth in its pure form. Therefore, it must be produced. Politicians and experts are focusing on the electrolysis of water to generate the new energy carrier. The electricity needed for this comes from wind power and photovoltaic plants, which already produce more electricity than can be consumed on windy and sunny days. This excess electricity is to be used to split water into hydrogen and oxygen. The hydrogen produced in this way, which is completely CO₂-free, is referred to as "green hydrogen".
