Utilization of Syngas Generated From Biomass Gasification Into Powering Solid Oxide Fuel Cell to Run EVs Charging Stations

This thesis, "Utilization of Syngas Generated from Biomass Gasification into Powering Solid Oxide Fuel Cell to Run EVs Charging Stations," presents a holistic approach to generating clean electricity through syngas produced from biomass gasification, aligning with the global initiatives for low-carbon future. The core of the thesis investigates the applicability of Solid Oxide Fuel Cells (SOFCs) for electricity generation using syngas produced from Gasification. SOFCs are identified as the most suitable fuel cells due to their high-temperature operation, tolerance to impurities, and substantial electrical efficiencies. The thesis methodically explores an integrated system coupling steam gasification of plastic waste with SOFC, where H2 production and SOFC performance are affected by varying gasification parameters. Optimal gasification conditions (1023 K temperature, steam/feed ratio of 1.5, and CaO/feed ratio of 1) are identified, directly influencing SOFC performance, with the maximum operating temperature for optimal power output at 1273 K. The practicality of this research is strengthened by a case study in Qatar, where the number of SOFCs required for an EV charging station serving 80 vehicles, with a daily charging requirement of 13 kWh per vehicle is calculated.

The study concludes that 5300 SOFCs of 10 cm x 10 cm size, each with a power output of 2.313145 W/cm², net power output component stack of 200.57 W at the ideal conditions would meet the station's daily energy demand of 1040 kWh, utilizing the highest ranked case scenario, 100% Municipal Solid Waste (Dates Seeds), amongst 11 different evaluated scenarios for different feedstocks and compositions from the Gasification system output. The findings are proof to the theoretical model's practicality in addition to the potential of SOFCs in supporting sustainable energy infrastructures within the electric vehicle sector. The thesis highlights the feasibility of alternative energy solutions and encourages continued research to optimize this integrated approach, paving the way for real-world applications and further advancements in sustainable energy systems.
