Long-Term Feasibility Assessment of Building-Level Carbon-Capturing Technology: A Life Cycle Thinking-Based System Dynamics Model
Buildings consume 40% of the energy and contribute significantly to global greenhouse gas (GHG) emissions (Cao et al. in Energy Build 128:198–213, 2016 [1]; Ürge-Vorsatz et al. in Renew Sustain Energy Rev 41:85–98, 2015 [2]). In Canada, 17% of the annual GHG emissions were related to the building sector (Feng et al. in J Clean Prod 250, 2020 [3]). Most of the building-related GHG emissions are contributed by the combustion of fossil fuels such as natural gas. Adopting carbon-capturing technologies in building-level fossil fuel-based heating systems can be considered a novel approach to reducing building-related GHG emissions. The current knowledge base indicates that one of the commercially available building-level carbon-capturing and utilization (BLCCU) technology that uses potassium hydroxide (KOH) to capture carbon dioxide (CO2) and generate potassium carbonate (K2CO3) as a by-product has a higher potential in reducing the life cycle GHG emissions with lesser economic burden or even economic benefits (Liyanage et al. in Feasibility study of integrating carbon capturing and utilization in building level natural gas heating systems, 2020 [4]). However, the long-term feasibility of this technology has not been thoroughly studied. Considering this research gap, this study aims to assess the long-term economic viability, environmental impacts, and social acceptability of the BLCCU technology using the system dynamics modelling technique. The study included life cycle GHG emissions and life cycle costs as main environmental and economic performance indicators. Social acceptability is modelled based on the generalized Bass model (Dhirasasna and Sahin in Renew Energy 163:1994–2007, 2021 [5]). Furthermore, the model is incorporated with technology learning, which impacts the investment cost, maintenance cost, carbon capture efficiency, and electricity energy consumption (Riahi et al. in Energy Econ 26:539–564, 2004 [6]). The system dynamics model was used to predict the impact on GHG emissions considering the conventional production of by-products under different potential business models during BLCCU technology adoption. In addition, the impacts of policy interventions such as subsidies on the technology adoption rate, environmental impacts, and economic impacts are also assessed by the developed model. The results revealed that the adoption rate of the BLCCU technology is highly sensitive to the by-product demand. Furthermore, it is necessary to determine the optimum stakeholder involvement considering the technological and market factors to deploy the BLCCU technology successfully. The findings of this study will assist community developers, policymakers, and researchers in planning climate mitigation actions.
