Project status:finished
Topic:Sustainable Energy
Scope of the project - Country:,
Aim of the project:The main aim of the PLASMAHYDROGEN project was to develop CGDE for efficient H2 generation as well as design a lab-scale pilot prototype of the plasma electrolyzer for future compensation for the long-term fluctuations of renewables.

About the project

PLASMAHYDROGEN developed an innovative plasma electrolytic application as a new, highly efficient renewable hydrogen-generating method. To increase the hydrogen productivity and power efficiency of the plasma electrolysis process, which is also referred to as contact glow discharge electrolysis (CGDE), four possible ways were investigated. These were:

  1. using CO2 and its dissociation product CO as a catalyst (so-called CO2 catalysis);
  2. a hybrid approach combining CGDE with subsequent catalytic reactions of the active species formed on the catalyst surface;
  3. use of a graphite glow discharge electrode; and
  4. realization of the CGDE of water in vacuum conditions.

Realization of CGDE in vacuum conditions led to a decrease in water vapor decomposition potential and an increase in CGDE power efficiency. The research project resulted in developing methods of plasma electrolytic hydrogen generation for renewable electricity storage as a possible way to compensate for the long-term fluctuations of renewable energy, such as wind and solar power. Alternative hydrogen-generating technology and a lab-scale pilot prototype of the glow discharge electrolyzer were created. In the future, using this new hydrogen-generating technology for renewable electricity storage will lead to renewables having a greater share in overall generation capacity and will decrease greenhouse gas emissions, especially CO2, which is a global challenge.
