dc.description.abstract | The unsustainable use of natural resources to power our world has depleted energy stores globally, and evokes a need to explore other environmentally-friendly options. This thesis presents a novel polygeneration design of a woody biomass-natural gas-nuclear energy-to-liquid-fuels and power (BGNTL) process, and assesses its economic and environmental feasibility in the context of Ontario, Canada. To assess the efficacy of nuclear energy in this system, a BGTL (biomass-natural gas to liquid fuels and power) system was compared with the BGNTL system. In both processes, carbon capture sequestration (CCS) was also incorporated. Many different cases of the plant were analyzed, including combinations of steam radiant syngas cooling (RSC), steam methane reforming integrated with the RSC (IR), and the addition or removal of CCS. It was found that for CCS cases, there was a positive relationship between the increase of CO2 tax and profitability. The optimal design produces only dimethyl ether (DME), uses no nuclear energy, and sends all of the off-gas to the solid-oxide-fuel-cell (SOFC). In the optimal case, the RSC making steam was slightly better than the IR by about 0.6% net-present-value (NPV), and a switch from non-CCS to CCS resulted in a 1% increase in NPV. Minimal DME prices to keep optimal cases profitable were around $798 - $807 for CCS and non-CCS cases, respectively. Overall, it was found that the life cycle CO2 impact in the optimal case of DME production was much less environmentally damaging compared with traditional diesel production. Specifically, in the CCS case, DME had approximately 100,000 less grams of CO2e / GJ of energy than a traditional diesel production. In the non-CCS case, the impact was approximately 50,000 less grams of CO2e / GJ of energy. | en_US |
