“…The intertwined nature of chemical production, power generation, and carbon capture promotes the study of these systems under an integrated purview. Chemical production of dense energy carriers (DECs), such as hydrogen, ammonia, and methanol, can reduce the energy storage requirement to address the problem of intermittency characteristic of renewable energy generation [1,2]. Moreover, carbon dioxide sequestration can be used to prolong the use of abundant natural gas resources, albeit in configurations that reduce carbon emissions [3].…”

The production of hydrogen-based dense energy carriers (DECs) has been proposed as a combined solution for the storage and dispatch of power generated through intermittent renewables. Frameworks that model and optimize the production, storage, and dispatch of generated energy are important for data-driven decision making in the energy systems space. The proposed multiperiod framework considers the evolution of technology costs under different levels of promotion through research and targeted policies, using the year 2021 as a baseline. Furthermore, carbon credits are included as proposed by the 45Q tax amendment for the capture, sequestration, and utilization of carbon. The implementation of the mixed-integer linear programming (MILP) framework is illustrated through computational case studies to meet set hydrogen demands. The trade-offs between different technology pathways and contributions to system expenditure are elucidated, and promising configurations and technology niches are identified. It is found that while carbon credits can subsidize carbon capture, utilization, and sequestration (CCUS) pathways, substantial reductions in the cost of novel processes are needed to compete with extant technology pathways. Further, research and policy push can reduce the levelized cost of hydrogen (LCOH) by upwards of 2 USD/kg.
