Abstract

Integrating carbon capture units in hydrogen production plants using steam methane reforming (SMR) can significantly reduce emissions but requires high energy inputs. This study investigates using solar thermal energy to power post-combustion carbon capture (PCC) systems in Tehran, Iran. Simulations in Aspen HYSYS 11 evaluate configurations to optimize CO₂ capture from SMR flue gases, focusing on minimizing reboiler energy demands. The optimal PCC model requires 71.5 MW of thermal energy, supplied by solar power plants simulated in Thermoflex. Parabolic trough collectors (PTC) and solar towers are assessed, requiring 0.87 km² and 1.91 km², respectively, for construction. Seasonal and daily performance analysis in SAM software reveals that the PTC system, with a solar multiple (SM) of 3.5, achieves an 80 % capacity factor (CF) and a levelized cost of heat (LCOH) of 5.60. The solar tower system, with an SM of 3, achieves a 90 % CF and an LCOH of 7.08. Exergoeconomic analysis indicates exergoeconomic factors of 24.51 % for the PTC system and 31.45 % for the solar tower. These findings demonstrate the potential of solar-assisted PCC systems to enhance sustainability in SMR-based hydrogen production.

期刊介绍： Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
