“…They achieved a 99.94%. purity with a water flux one to two orders of magnitude higher than other membrane approaches used for capture (e.g., membrane contactors and RO membrane crystallizers) [ 51 ]. However, until now none of these biomimetic approaches have found any commercial application.…”

Biomimetic membranes are attracting increased attention due to the huge potential of using biological functional components and processes as an inspirational basis for technology development. Indeed, this has led to several new membrane designs and applications. However, there are still a number of issues which need attention. Here, I will discuss three examples of biomimetic membrane developments within the areas of water treatment, energy conversion, and biomedicine with a focus on challenges and applicability. While the water treatment area has witnessed some progress in developing biomimetic membranes of which some are now commercially available, other areas are still far from being translated into technology. For energy conversion, there has been much focus on using bacteriorhodopsin proteins, but energy densities have so far not reached sufficient levels to be competitive with state-of-the-art photovoltaic cells. For biomedical (e.g., drug delivery) applications the research focus has been on the mechanism of action, and much less on the delivery ‘per se’. Thus, in order for these areas to move forward, we need to address some hard questions: is bacteriorhodopsin really the optimal light harvester to be used in energy conversion? And how do we ensure that biomedical nano-carriers covered with biomimetic membrane material ever reach their target cells/tissue in sufficient quantities? In addition to these area-specific questions the general issue of production cost and scalability must also be treated in order to ensure efficient translation of biomimetic membrane concepts into reality.

“…Membraneassisted crystallization has been introduced to create reproducible crystals with appropriate sizes and shapes in an energy efficient way without compromising quality [225,226]. The second advantage of membrane crystallization is that renewable energy sources can be used to supply energy to the process and this can contribute to sustainable development [227]. Biomimetic FO membranes have been tested for the crystallization of Na2CO3 from aqueous solution of NaOH in the scenario of carbon capture from flue gases [227].…”

A membrane material that can concurrently provide commercially acceptable levels of water permeability, high salt rejection, and of sufficient stability to withstand mechanical and chemical stresses seems to be necessary to guarantee the energy and environmental sustainability of desalination systems and other membrane separation processes. Recent developments in desalination have shown that bio-inspired membranes are moving steadily in this direction. Sustainable desalination via aquaporin-based bio-inspired membranes is elucidated in this paper in terms of recent commercialization exploitation and progress towards real operations. Current large-scale applications, viable opportunities, remaining challenges and sustainability of operations, in terms of comparison with established technologies, are discussed in this paper. The major drawback of aquaporin-based membranes, which has been highlighted repeatedly in recent studies, is the stability of the membranes during real operations. This review is focused on recent solutions provided by scientists towards the mitigation of these problems and commercialization of aquaporin-based membranes.

“… Aquaporin-based FO membrane assisted crystallization of Na 2 CO 3 , allowing its reuse, after CO 2 capture from flue gases by an alkaline solution. By proper control of the super-saturation level high purity crystallization of Na 2 CO 3 ·10H 2 O crystals can be achieved and aquaporin membranes may be a promising alternative to existing methods for Na 2 CO 3 crystallization in a CO 2 capture scenario [ 26 ]. The most developed technology today for CO 2 capture is amine-based absorption.…”

The discovery of selective water channel proteins—aquaporins—has prompted growing interest in using these proteins, as the building blocks for designing new types of membranes. However, as with any other new and potentially disruptive technology, barriers for successful market entry exist. One category includes customer-related barriers, which can be influenced to some extent. Another category includes market-technical-related barriers, which can be very difficult to overcome by an organization/company aiming at successfully introducing their innovation on the market—in particular if both the organization and the technology are at early stages. Often, one faces barriers from both these categories at the same time, which makes it necessary to gain insight of the particular market when introducing a new innovative product. In this review we present the basic concepts and discuss some of these barriers and challenges associated with introducing biomimetic aquaporin membranes. These include technical issues in membrane production and product testing. Then we discuss possible business models for introducing new technologies in general, followed by a presentation of beach-head market segments relevant for biomimetic aquaporin membranes.
