“…Chen and co-workers 44 introduced an integration of BMED and a crystallization chamber to simultaneously capture CO 2 and extract nesquehonite (MgCO 3 •3H 2 O) from seawater at pH levels below 11. However, it is worth noting that the presence of OH − in the alkali chamber led to membrane fouling due to the low solubility of Mg(OH) 2 .…”

“…Also, BMED is ecologically friendly, requiring no chemical reagents for recovery (e.g., lime or sodium carbonate). The production of a basic and acidic recovery stream provides an economic opportunity to co-recover other industrial minerals, such as boron (Jiang et al, 2014;Yang et al, 2014;Hwang et al, 2016;Bunani et al, 2017a;Bunani et al, 2017b;Chen et al, 2022).…”

Under the Paris Agreement, established by the United Nations Framework Convention on Climate Change, many countries have agreed to transition their energy sources and technologies to reduce greenhouse gas emissions to levels concordant with the 1.5°C warming goal. Lithium (Li) is critical to this transition due to its use in nuclear fusion as well as in rechargeable lithium-ion batteries used for energy storage for electric vehicles and renewable energy harvesting systems. As a result, the global demand for Li is expected to reach 5.11 Mt by 2050. At this consumption rate, the Li reserves on land are expected to be depleted by 2080. In addition to spodumene and lepidolite ores, Li is present in seawater, and salt-lake brines as dissolved Li+ ions. Li recovery from aqueous solutions such as these are a potential solution to limited terrestrial reserves. The present work reviews the advantages and challenges of a variety of technologies for Li recovery from aqueous solutions, including precipitants, solvent extractants, Li-ion sieves, Li-ion-imprinted membranes, battery-based electrochemical systems, and electro-membrane-based electrochemical systems. The techno-economic feasibility and key performance parameters of each technology, such as the Li+ capacity, selectivity, separation efficiency, recovery, regeneration, cyclical stability, thermal stability, environmental durability, product quality, extraction time, and energy consumption are highlighted when available. Excluding precipitation and solvent extraction, these technologies demonstrate a high potential for sustainable Li+ extraction from low Li+ concentration aqueous solutions or seawater. However, further research and development will be required to scale these technologies from benchtop experiments to industrial applications. The development of optimized materials and synthesis methods that improve the Li+ selectivity, separation efficiency, chemical stability, lifetime, and Li+ recovery should be prioritized. Additionally, techno-economic and life cycle analyses are needed for a more critical evaluation of these extraction technologies for large-scale Li production. Such assessments will further elucidate the climate impact, energy demand, capital costs, operational costs, productivity, potential return on investment, and other key feasibility factors. It is anticipated that this review will provide a solid foundation for future research commercialization efforts to sustainably meet the growing demand for Li as the world transitions to clean energy.

This paper reports on tests performed with the dual aim of minimizing the energy use (kilojoules per kilogram) and maximizing the conversion rate (kilograms per hour) of bipolar membrane electrodialysis (BPMED) for the regeneration of chemicals needed for the effective scale-up of the accelerated CO 2 mineralization route developed at Åbo Akademi University (ÅA). The performance of two-and three-compartment stacks was compared with ammonium sulfate (AS) and ammonium bisulfate (ABS) as the input product feed, yielding sulfuric acid and aqueous ammonia, respectively, as the final products. It was shown that a two-compartment stack is more efficient with regard to energy use (i.e., electricity consumption), with values in the range of 3630− 4844 kJ/kg of AS or ABS, compared to the three-compartment stack requiring 5102−7223 kJ/kg of AS or ABS. A maximum conversion rate of ∼0.13 kg/h was achieved with the two-compartment stack. We also concluded that approximately 25% of the energy needed for the process may give off heat, depending primarily on the voltage applied to the membrane stack. A twocompartment stack will require fewer membranes, which is an obvious benefit in terms of maintenance and cost. Furthermore, we concluded that AS provides a more efficient conversion than ABS, when considering both energy use and the amounts of the solution that need to be recycled in the BPMED step.
