Renewable gases and power-to-gas technologie

The topic has become an increasingly important strategic goal for the research base of the University of Miskolc in recent decades. Combustible gases derived from fossil sources are expected to persist for many years, given current trends. However, it can be predicted that climate protection efforts will gradually lead to the replacement of fossil fuels. The utilization of biogases from various sources (sewage gas, landfill gas, agricultural biogas) has decades of experience, and hydrogen has emerged as one of the most popular topics in recent years.

Power to Gas (PtG) technologies are at the forefront of energy conversion and storage, providing an excellent opportunity to convert irregularly generated electricity from renewable sources into a storable form. The stored gas can be methane and hydrogen. Research in this field encompasses electricity, methane, hydrogen, carbon dioxide, gas storage, pipeline transportation, and utilization.
