Keeping global warming at 2 degrees and below as stated in the "Paris Climate Agreement" and minimizing emissions can only be achieved by establishing a hydrogen (H 2 ) ecosystem. Therefore, H 2 technologies stand out in terms of accomplishing zero net emissions. Although H 2 is the most abundant element in the known universe, molecular H 2 is very rare in nature and must be produced. In H 2 production, reforming natural gas and renewable hydrogen processes using electrolyzers comes to the fore. The key to all these technologies is to enhance production speed, performance, and system lifetime. At this point, composite membranes used in both processes come to the fore. This review article summarizes composite membrane technologies used in methane, ethanol, and biomass steam reforming processes, proton exchange membranes, alkaline water electrolysis, and hybrid sulfur cycle. In addition to these common H 2 production technologies at large quantities, the innovative systems developed with solar energy integration for H 2 generation were linked to composite membrane utilization. This study aimed to draw attention to the importance of composite membranes in H 2 production. It aims to prepare a guiding summary for those working on membranes by combining the latest and cutting-edge studies on this subject.

“…Both technologies have advantages and disadvantages. The fuel cell is known to emit only water and reaches high efficiency [6] but requires a high degree of hydrogen purity [7]. The H 2 ICE can burn hydrogen, even of low purity, but produces NO x emissions in the process.…”

The results shown in this paper extend our research group’s previous work, which presents the theoretically achievable hydrogen engine-out NOxeo (H2-NOxeo) Pareto front of a hydrogen hybrid electric vehicle (H2-HEV). While the Pareto front is calculated offline, which requires significant computing power and time, this work presents an online-capable algorithm to tackle the energy management of a H2-HEV with explicit consideration of the H2-NOxeo trade-off. Through the inclusion of realistic predictive data on the upcoming driving mission, a model predictive control algorithm (MPC) is utilized to effectively tackle the conflicting goal of achieving low hydrogen consumption while simultaneously minimizing NOxeo. In a case study, it is shown that MPC is able to satisfy user-defined NOxeo limits over the course of various driving missions. Moreover, a comparison with the optimal Pareto front highlights MPC’s ability to achieve close-to-optimal fuel performance for any desired cumulated NOxeo target on four realistic routes for passenger cars.

“…17–19 Due to the small atomic radius of the hydrogen atom, it can easily diffuse through certain metal alloys allowing selective separation of H 2 from a gas mixture. 20 Recent developments in nanoelectronics also made hydrogen an ideal instrument to tune the functional properties of materials in a controllable and systematic way. 21–24 The small size of hydrogen makes it a special intercalation ion to dynamically enter and leave a crystal structure alternating the properties of host materials under applied electric field.…”
