Special Issue Information

Dear Colleagues,

Through the rapid development and scaling-up of renewables and energy storage technology for realizing carbon neutrality targets, fossil-based energy remains firmly in place as the most significant power source and consumes the most fossil fuel globally. CO2 capture, utilization, and storage (CCUS) technology is the only crucial technology for decarbonizing the existing fossil energy infrastructure without dramatic changes. When fossil energy retrofitted with CCUS is coupled with carbon-negative fuels and renewables—e.g., biomass—municipal solid waste, fossil fuel, and fossil-based energy could be carbon-neutral. Meanwhile, fossil-based power with CCUS technology is expected to be a ballast for energy security and flexibility, especially when an energy system with large-fraction renewables and limited energy storage faces extreme weather conditions. However, the percentage of low-carbon fossil power that can be retained globally in green energy systems depends on many factors. These factors include technical advances, cost competitiveness, the optimization of energy trilemma (energy security, energy equity (accessibility and affordability), environmental sustainability), and the supportive policies of different energy sources.

This Special Issue aims to collate multiple-scale investigations with novel solutions and review papers with state-of-the-art findings that can significantly contribute to the energy community. Even though this Special Issue is open to all communications related to CCUS technology in green energy systems, potential focus areas are summarized as the following:

  • Status, strength, weakness, opportunities, and challenges for CCUS technology in different regions; 
  • Technical challenges (energy security, energy equity, environmental sustainability);
  • Environmental, economic, and sustainability impacts;
  • Synthetic impact of CCUS and other carbon-neutral technologies;
  • Regulations and legislations;  
  • Social and economic aspects;
  • Supply chain of CCUS;
  • Commercialization of CCUS technology;
  • Synthetic CCUS technology realizing the carbon neutrality of energy systems;
  • Innovative methods enhancing the competitiveness of CCUS technology.

Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, the absorption process frequently suffers from various operational issues, including foaming. The main objective of the current work is to elucidate the effect of degradation product on the foaming behavior in methyldiethanolamine (MDEA) and piperazine (PZ) solution and evaluate the antifoaming performance of polydimethylsiloxane (PDMS) antifoam. The foaming behavior was investigated based on types of degradation product, temperature, and gas flow rate. The presence of glycine, heptanoic acid, hexadecane, and bicine in MDEA-PZ solution cause significant foaming. The presence of hexadecane produced the highest amount of foam, followed by heptanoic acid, glycine and lastly bicine. It was found that increasing the gas flow rate increases foaming tendency and foam stability. Furthermore, increasing temperature increases foaming tendency, but reduces foam stability. Moreover, PDMS antifoam was able to reduce foam formation in the presence of different degradation products and at various temperatures and gas flow rates. It was found that PDMS antifoam works best in the presence of hexadecane with the highest average foam height reduction of 19%. Hence, this work will demonstrate the cause of foaming and the importance of antifoam in reducing its effect. Full article
