Yes — your idea about ceramic filtering membranes for hydrogen production and separation is still an active area of research, and there have been multiple notable advances recently even if we’re not yet at widespread commercial deployment. Here’s a current, grounded view of where the science stands (including innovative work you might not have seen yet):

==== ### ====

Researchers in Germany (Forschungszentrum Jülich) developed two-phase ceramic membranes that significantly improve hydrogen separation throughput. These dense ceramic materials combine ionic and electronic conductivity, enabling hydrogen protons and electrons to move separately through the membrane — nearly doubling flow rates compared to earlier versions. The American Ceramic Society<ref>{{cite web|title=The American Ceramic Society|url=https://ceramics.org/ceramic-tech-today/ceramic-hydrogen-separation-membrane-doubles-flow-rate-could-enable-clean-energy/|publisher=The American Ceramic Society|access-date=2025-12-20}}</ref>

===== A team from the Chinese Academy of Sciences created a multilayer ceramic membrane via a novel “interface reaction-induced reassembly” technique. These membranes resist chemical degradation and maintain performance over 1,000+ hours of operation, which is a major step toward stability in real operating environments rather than short lab tests.

===== Proton-conducting ceramic membranes — essentially ceramic electrolytes that separate and transport hydrogen protons — have been integrated into reactors capable of producing hydrogen with ultra-low energy loss. In some research, this combines the chemical production and separation steps in one membrane system, potentially improving efficiency significantly at industrial scales.

===== Companies like NGK Insulators and MHI are actively combining ceramic membrane separation with ammonia/hydrogen cracking and purification — not exactly the same as production membranes but very relevant for hydrogen value-chain integration (e.g., cracking ammonia into hydrogen for transport and storage).

==== Your idea — using ceramic membranes to produce and/or separate hydrogen efficiently — is exactly the direction several labs and industry-academic teams are pursuing: ====
* Ceramic membranes can combine chemical reaction and separation in one step, potentially eliminating energy losses associated with multi-stage hydrogen production. ChemEurope<ref>{{cite web|title=ChemEurope|url=https://www.chemeurope.com/en/news/1175770/new-system-based-on-protonated-ceramic-membranes-produces-hydrogen-industrially.html|publisher=chemeurope.com|access-date=2025-12-20}}</ref>
* Durability and integration into industrial processes are improving, meaning membranes are operating for thousands of hours, not just hundreds. Phys.org<ref>{{cite web|title=Phys.org|url=https://phys.org/news/2022-11-approach-fabricating-ion-conducting-ceramic-membranes.html|publisher=phys.org|access-date=2025-12-20}}</ref>
* Research is expanding beyond lab curiosity toward engineering-scale reactor designs and membrane stacks that could scale. RSC Publishing<ref>{{cite web|title=RSC Publishing|url=https://pubs.rsc.org/en/content/articlehtml/2024/re/d4re00372a|publisher=RSC Publishing|access-date=2025-12-20}}</ref>

At least one international team has already demonstrated an industrial hydrogen production system using proton-conducting ceramic membranes, and this work was published in Science, which means your conceptual niche is confirmed as scientifically legit and under development. Quimica<ref>{{cite web|title=Quimica|url=https://www.quimica.es/noticias/1175770/producen-hidrogeno-de-forma-industrial-mediante-un-nuevo-sistema-basado-en-membranas-ceramicas-protonicas.html|publisher=quimica.es|access-date=2025-12-20}}</ref>

==== Despite progress, some barriers remain: ====

===== Many ceramic membrane concepts work beautifully in controlled lab tests but lose performance when scaled up due to: =====
* sealing and mechanical integrity under high temperature
* maintaining long-term chemical stability
* integration with feedstock handling

Hybrid systems and modular stacks are being actively explored to overcome this. RSC Publishing<ref>{{cite web|title=RSC Publishing|url=https://pubs.rsc.org/en/content/articlehtml/2024/re/d4re00372a|publisher=RSC Publishing|access-date=2025-12-20}}</ref>

===== Some approaches still require high temperatures (400–800 °C) or energy inputs that are only feasible with waste heat or industrial synergies — a challenge for decentralized hydrogen production. The American Ceramic Society<ref>{{cite web|title=The American Ceramic Society|url=https://ceramics.org/ceramic-tech-today/ceramic-hydrogen-separation-membrane-doubles-flow-rate-could-enable-clean-energy/|publisher=The American Ceramic Society|access-date=2025-12-20}}</ref> =====

===== Full commercial membranes for hydrogen separation from water/electrolysis processes are still emerging — ceramic prototypes are promising, but large-scale industrial production infrastructure hasn’t yet matured universally. Taylor & Francis<ref>{{cite web|title=Taylor & Francis|url=https://www.taylorfrancis.com/chapters/edit/10.1201/9781003382522-7/hydrogen-separation-using-ceramic-membranes-fatemeh-kavousi-anna-sullivan-archishman-bose-sudipta-de|publisher=Taylor & Francis|access-date=2025-12-20}}</ref> =====

==== ✔ Ceramic membranes are increasingly seen as a credible pathway to: ====
* low-loss hydrogen production
* efficient separation on industrial scales
* integration with chemical reactors and clean energy systems

✔ New research shows:
* much higher throughput
* very long operation durability
* novel fabrication techniques that improve membrane integrity and performance The American Ceramic Society<ref>{{cite web|title=The American Ceramic Society|url=https://ceramics.org/ceramic-tech-today/ceramic-hydrogen-separation-membrane-doubles-flow-rate-could-enable-clean-energy/|publisher=The American Ceramic Society|access-date=2025-12-20}}</ref>
