The depletion of fossil fuels and environmental pollution (e.g., greenhouse gas emissions) through the combustion of fossil fuels have stimulated studies on new technologies able to curtail the energy consumption of existing fractionation units. In this regard, heat pumps have garnered substantial attention due to their potential to improve the process energy efficiency. This study aims to provide extensive economic analysis and environmental impact assessment of the application of heat pumps under different conditions and scenarios. For this purpose, we first selected three important conditions: feed composition, plant capacity, and fuel price. Then, we performed a range of analyses to identify the major costs and environmental drivers. The economics and environmental impact of heat pump-assisted distillation was investigated and compared with those of conventional distillation.

“…Renewable energy (RE) is expected to play a key role in future energy systems as it is clean and sustainable [ 2 ]. However, some key challenges, such as its variable and intermittent nature [ 3 , 6 , 7 ] remain to be addressed before completely transitioning towards RE [ 2 ]. The solution to this problem lies in adequate large-scale energy storage, which would increase energy supply reliability [ 8 ].…”

“…Energy storage can provide energy flexibility and will reduce the global dependence on fossil fuel backup power. Various types of energy storage systems exist [ 6 , 9 , 10 ]. These can be broadly categorized [ 8 ] as electrochemical (batteries) [ 11 ], chemical (hydrogen systems: Fuel cells/electrolyses [ 12 , 13 , 14 ]), electrical (capacitors, super capacitors and ultra-capacitors) [ 15 , 16 ], mechanical (flywheels [ 17 , 18 , 19 ], compressed air [ 20 , 21 ] and pumped hydro-storage [ 22 , 23 ]) and thermal (hot water, sensible/latent heat storage, solar energy storage) [ 24 , 25 , 26 , 27 , 28 ], and magnetic (superconducting energy storage) [ 29 ].…”

Recent Advances in Membrane-Based Electrochemical Hydrogen Separation: A Review

2021

View full text Add to dashboard Cite

In this paper an overview of commercial hydrogen separation technologies is given. These technologies are discussed and compared—with a detailed discussion on membrane-based technologies. An emerging and promising novel hydrogen separation technology, namely, electrochemical hydrogen separation (EHS) is reviewed in detail. EHS has many advantages over conventional separation systems (e.g., it is not energy intensive, it is environmentally-friendly with near-zero pollutants, it is known for its silent operation, and, the greatest advantage, simultaneous compression and purification can be achieved in a one-step operation). Therefore, the focus of this review is to survey open literature and research conducted to date on EHS. Current technological advances in the field of EHS that have been made are highlighted. In the conclusion, literature gaps and aspects of electrochemical hydrogen separation, that require further research, are also highlighted. Currently, the cost factor, lack of adequate understanding of the degradation mechanisms related to this technology, and the fact that certain aspects of this technology are as yet unexplored (e.g., simultaneous hydrogen separation and compression) all hinder its widespread application. In future research, some attention could be given to the aforementioned factors and emerging technologies, such as ceramic proton conductors and solid acids.
