Assessment of promising syngas compositions and associated contaminant levels for SOFCs, based on an extensive literature study

Selection of the two most promising biomass feedstocks, suitable for power generation with SOFCs, after gasification with a BFB gasifier and high temperature gas cleaning, and following after a screening of 10 samples and 5 mixtures of potential biomass feedstocks  [check the deliverable];

Determination of gas cleaning strategies which revealed the most promising primary and secondary sorbents to reduce sulphur and chlorine bearing compounds in the syngas, as well as catalysts to be applied within a secondary tar reformer; 

Mechanistic behaviour and long-term stability of the SOFCs operated with relevant syngas compositions (on-going);

Literature review to select bio-syngas representative organic and inorganic contaminants for button cell and short-stack SOFC tests;

In order to deeply understand the impact of sufficiently cleaned BFB gasifier gas on the SOFC performance (both on single cell level and short-stack level), prior to testing the pilot-plant;

Assessment of different plant designs (pilot plant + commercial), based on plant simulations;

Realization of the of the pilot-plant (on-going), focusing on efficiency optimisation, and including gas recirculation with a steam-driven microturbine;
