FLEDGED Project: Sorption Enhanced biomass gasification and DME synthesis by flexible technologies for power-to-DME conversion

FLEDGED H2020 project developed a complete solution for biomass to DME conversion, exploiting the advantages of Sorption-Enhanced processes. The result is a highly intensified and flexible process that can: (i) convert a wide variety of feedstocks, (ii) be integrated with electrolysis for intermittent Power-to-DME operation and (iii) be designed or retrofitted for CO2 capture and storage, leading to negative emission system via bio-CCS. The project consortium worked in the past four years, improving the knowledge in several fields related with biofuels. The key findings of the project will be presented in this half-day workshop:

  • The validation in relevant environment (TRL5) of the flexible Sorption-Enhanced biomass gasification process in two experimental facilities for SEG operation, focusing on feedstock flexibility, operational flexibility, conversion efficiency and content of contaminants in the syngas.
  • The validation in relevant environment (TRL5) of the sorption-enhanced DME synthesis (SEDMES) process, through testing of the complete cyclic operation of the system.
  • The process integration, risk analysis, environmental impact and socio-economic analysis of the complete biomass to fuel conversion process, including the assessment of flexible operation for renewable Power-to-DME conversion.
  • The feasibility analysis and business case studies considering both large-scale industrial production and small-scale system integrated in the municipal waste collection and recycling process.
