Energy Transition. Hydrogen. Sector coupling.
Climate protection has become an integral part of public and political discussions. The 2015 Paris Climate Agreement pursues the ambitious goal of limiting global warming to 1.5 °C in relation to the pre-industrial level. The drastic reduction in global CO2 emissions is seen as a key success factor. In addition to saving energy through increased efficiency, the consistent use of renewable energies will make a significant contribution to achieving these goals. The direct use of electricity generated from renewable sources is generally desirable, but not feasible or wise in all applications.
In these cases, hydrogen is playing an essential role. Hydrogen can be produced in large quantities from renewable electricity, it can be stored and distributed. As a secondary energy carrier, hydrogen enables a temporal and regional decoupling between energy generation and energy consumption. This characteristic becomes even more important, when fluctuating renewable energies are consistently gaining shares within in the energy system. A so-called hydrogen economy will be established around the production, distribution and use of hydrogen. It enables a fundamental step towards the use of synergy effects in terms of climate protection: sector coupling. The previously very independent sectors of electricity, heating, transport and industry will be linked by hydrogen. A balance between energy supply and demand will therefore be simplified across sectors by the use of hydrogen.

What is the energy transition simply explained?
What is hydrogen simply explained?
What is sector coupling simply explained?
What are the properties of hydrogen?
Is hydrogen dangerous?
How can (green) hydrogen be produced?
Hydrogen can also be produced CO2-free via the electrochemical process of electrolysis. Using green electricity, the water molecule (H2O) is split into its components hydrogen and oxygen without causing CO2 emissions directly during electrolysis or indirectly during upstream electricity production.
How much electricity does it take to produce 1 kg of hydrogen?
What does 1 kg of hydrogen cost to produce?
The production costs via the CO2 free process of electrolysis are about 5 €/kg. These costs are strongly influenced by the investment costs and the utilization of the electrolysis, the purchase costs of the green electricity and the applicable levies. The imminent industrialization of electrolysis production suggests cost degressions.
The production costs of hydrogen do not include the costs for storage, transport and delivery of the hydrogen.
