Development of a New and Highly Efficient Micro-Scale CHP System Based on Gasification and a SOFC

  • Project no.250075
  • Duration 05/2015 - 04/2019

The EU Horizon 2020 project "FlexiFuel-SOFC" aims at the development of a new innovative, highly efficient and fuel flexible micro-scale biomass CHP technology consisting of a small-scale fixed-bed updraft gasifier, a compact gas cleaning system and a solid oxide fuel cell (SOFC). The technology shall be developed for a capacity range of 25 to 150 kW (fuel power) and shall be characterised by a wide fuel spectrum applicable (wood pellets and wood chips of various sizes and moisture contents, SRC, selected agricultural fuels), high gross electric and overall efficiencies as well as almost zero gaseous and PM emissions. This aim shall be reached by the combination of a fuel-flexible updraft gasification technology with ultra-low particulate matter and condensed alkaline compound concentrations in the product gas, which reduces the efforts for gas cleaning, an integrated gas cleaning approach for dust and HCl removal, desulphurisation and tar cracking as well as a SOFC system which tolerates certain amounts of tars as fuel. The objective of the project is the development of a micro-scale CHP technology with extended fuel flexibility which shall be robust, cost efficient and distinguish itself by high electric and overall efficiencies as well as almost zero emissions.

To fulfil these goals an overall methodology shall be applied which is divided into a technology development part (based on process simulations, computer aided design of the single units and the overall system, test plant construction, performance and evaluation of test runs, risk and safety analysis) as well as a technology assessment part covering risk, techno-economic, environmental and overall impact assessments, market studies regarding the possible potentials for application of the new technology as well as dissemination activities. Within the consortium, the Wuppertal Institute is responsible for the environmental and overall impact assessment as well as for the publication and dissemination activities.

This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 641229.
