5. Conclusions

With increasing shift towards sustainable energy production, waste gasification is certainly providing multiple solutions such as sustainable waste management and clean energy production. In Europe, district heating schemes are now regularly powered by combined heating and power (CHP) plants. Therefore, gasification to steam cycle experienced a shift towards ultraclean syngas injection into CHP plant with heat recovery for district heating and cooling (DHC) systems. Moreover, there is a significant interest in high-temperature fuel cell applications of syngas with heat recovery after the emergence of solid oxide fuel cells (SOFC). As the carbon capture and storage is becoming high on the strategic agenda, the use of oxygen during gasification is becoming the norm. Therefore, emerging research into ceramic ionic transport membranes (ITM) to produce high purity oxygen for gasification at elevated temperature is leading the way into the new market.
