abstract

  • Hydrocarbon resource centric economies, such as Qatar, are highly vulnerable to the impact of climate policy. Climate policies could decrease demand of hydrocarbon, lowering prices and would force countries to adopt mitigation technologies. Thus, having a climate strategy is important to meet future constraints. This work develops approaches to enable policy makers to systematically explore alternative emissions reduction paths in an integrated framework. The methods introduced explore the element of time, resources management, Carbon Capture Utilization and Sequestration (CCUS) and energy integration including Renewable Energy (RE) use. The industrial city or cluster is taken as a system and modelled through balances and constraints, which were optimized applying deterministic solvers. Two approaches were developed. The first is a multi-period carbon planning approach that enables the assessment of different carbon dioxide reduction options, which may be applied to guiding transitions to a future target emission. Second is a systematic approach that enables the identification of economically optimal natural gas allocation in different conversion technologies under carbon emission targets with energy synergy. The multi-period planning approach identified allocation of carbon dioxide between sources and potential sinks in each period, compared cost elements simultaneously and resulted in a low cost network across all periods. Furthermore, the role of RE was investigated through a robust MILP. The results highlighted significant differences in economic impact of alternative footprint reduction policies. The systematic natural gas monetization approach simultaneously determined natural gas monetization and carbon dioxide management through CCUS as well as RE strategies. The method considered heat and power integration, enabling the assessment of the Natural gas (CH?), CO? and Energy nexus. Several case studies were solved that indicated benefits of having optimized policies that screen all mitigation options given economic and environmental objectives out preformed adopted prescribed policies found around the globe.
