Joint Research Unit of Renewable Gas Consolidation

NameJoint Research Unit of Renewable Gas Consolidation
Start DateAugust 2020
End DateDecember 2023
PartnersThe Renewable Gas Mixed Unit is a joint project between Naturgy, Energylab Technology Centre and EDAR Bens S.A., a supra-municipal public company that provides a waste water purification service in the municipalities of A Coruña, Arteixo, Cambre, Culleredo and Oleiros.
Financing entitiesThis Mixed Unit is co-funded by the Galician Innovation Agency - Second Deputy President's Office and Regional Ministry of Economy, Enterprise and Innovation, and by the European Regional Development Fund (ERDF) under the framework of the 2014-2020 ERDF Galicia operating programme. Boosting research, technological development and innovation. A way of making Europe.


The project’s aim is to increase knowledge not just of biogas and biomethane but also of other renewable gases such as green hydrogen and syngas, as well as assessing their impact on current infrastructures and end users.


The Mixed Unit will develop five new lines of research:

  • Improving biogas production through co-digestion and recovery of nutrients.
  • Generating green hydrogen by harnessing energy from pure water flows. This will be passed through turbines, generating hydrogen by means of water electrolysis.
  • Producing biohydrogen through dark fermentation, a biological process (initial stages of anaerobic digestion) through which hydrogen is generated based on the degradation of organic matter.
  • Gasification of sewage sludge to obtain bio-syngas (synthetic biogas).
  • Studying the impact of using the various renewable gases and their mixtures, from the point of view of injection into the gas grid and its use in stationary and mobile (vehicle) applications.
