What is Thermodynamics assessment and dynamic simulation of a low-carbon syngas-fueled SOFC system using a green hydrogen blend about?

Green hydrogen is currently eye-catching in terms of its production, storage and delivery to facilitate energy transition. In the present research, it is tried to demonstrate the capability of green hydrogen in blending with syngas (produced by biomass gasification) to feed an SOFC system in order to supply electrical power and heating for an existing educational building. Dynamic simulation has been performed in TRNSYS Software to calculate the hydrogen production annually at different scenarios. Effects of hydrogen concentration in the fuel mixture on the performance of the proposed CHP system are assessed. Results indicated that utilizing a reasonable roof area can offer approximately 10,000 kg H2 and 70,000 kg H2 per year in cases of grid-zero connected and grid 85% connected, respectively. It is revealed that increasing the hydrogen share in fuel mixture from 5% to 30% increases noticeably the hydrogen gas percentage at the SOFC anode inlet and outlet while it has a reverse effect on the H2O amount. In addition, the studied increment in hydrogen share could increase 18% of the net output power from the system. Finally, related to the CO2 emission from the system, it is found t
