Renewable gases and power-to-gas technologies

The topic has become an increasingly important strategic goal of the research base of University of Miskolc in the recent decades. Combustible gases from fossil sources still have many years to go, given to current trends, but on the other hand it can be predicted that climate protection efforts will not avoid the gradual replacement of fossil fuels. The utilization of biogases from different sources (sewage gas, landfill gas, agricultural biogas) has many decades of experience, and hydrogen has become one of the most popular topics of recent years.

Power to Gas (PtG) technologies are pioneers in energy conversion and storage, providing an excellent opportunity to convert non-uniformly generated electricity from renewable sources into a storable form. The stored gas can be methane and hydrogen. Research links electricity, methane, hydrogen, carbon dioxide, gas storage, pipeline transportation and use.
