Feeding biogas and wood gas into the natural gas grid by upgrading or Power-to-Gas

This research area focuses on improving the upgrading of biogas from anaerobic digestion and wood gasifiers into grid-quality biomethane, including Power-to-Gas technologies. Key areas of work include Power-to-Gas applications, which allow using CO2 from biogas in combination with hydrogen to produce biomethane.

Description of Research Area

In the research area “biomethane” existing and improved technologies for biomethane production are compared. The technology monitoring covers all relevant national and international biomethane projects and will be updated once a year. The following challenges are adressed:

  • Identification and evaluation of the most promising technologies and operation conditions for industrial applications of Power-to-Gas in biogas/waste water treatment plants
  • Development and optimization of the design of catalytic and biological methanation process/reactors for industrial Power-to-Gas applications using biomass as carbon source
  • Scaling-up catalytic fluidized bed methanation processes to industrial scale
  • Enabling cost- and energy efficient gas cleaning processes, at high or low temperatures, for removal of relevant contaminants
  • Use of techno-economic assessments to optimize wood-to-SNG plants with optional Power-to-Gas application
  • Support of pilot and demonstration projects by knowledge transfer during engineering phase and measurement/diagnostics campaigns during the commissioning
