Knowledge Platform

In the conventional energy supply it is common to convert gas (chemical energy) to electricity (electric energy). Power-to-gas technologies reverse that process and thus the technology transforms electricity to gas. The gas is either hydrogen (power-to-hydrogen) or methane (power-to-methane). Both gases can be used as fuels in mobility, for heating and cooking, or for generating electricity. 

Forecasts assume that the future electricity demand can be supplied with electricity from renewable sources, such as photovoltaic, wind and combined heat and power systems. It is also expected that a surplus will be produced in the summer. On the one hand, power-to-gas technologies can be used to intercept these surpluses and thus stabilize the electricity grid. On the other hand, the surplus power from summer can be transformed to gas and in this form can be stored to the winter season. Synthetic methane can even be stored in the existing gas grid. The environmental impact of the synthetic gas is significantly lower than that of fossil gas, if the electricity comes from renewable sources. 

Science for Professionals and the Public 

IET generates practical and scientific knowledge in the field of power-to-gas due to its activities in research projects and its teaching in the Bachelor of Science in Renewable Energies and Environmental Technology. In this section, experts and the interested public will receive information, teaching aids and research results on power-to-gas technologies:
