The focus of DYNAPRO is to achieve increased efficiency and production of hydrogen under dynamic and cost effective conditions. The core technology utilize high temperature proton conducting ceramic electrochemical cells which can separate hydrogen form hydrogen containing gaseous mixtures. When hydrogen is electrochemically separated it is possible to overcome thermodynamic limitations ? this is demonstrated for the endothermic reactions steam methane reforming, water electrolysis and ammonia dehydrogenation in the project. Furthermore, separating hydrogen electrochemically generates heat through Joule heating ? as such, when coupled with endothermic reactions, high energy efficiencies can be obtained. This is analysed in the project using computational fluid dynamic models. The core components of the cells have now been analysed experimentally and new improved cells are under evaluation. Here, we focus especially on the electrodes where we have observed that the microstructure and composition dominates the resistance of the cells. Project partners are CoorsTek Membrane Sciences (project lead), University of Oslo (researcher position and PhD student) and CSIC-ITQ (supervision and access to advanced instruments).

Renewables are diffusing rapidly into electrical grids, thereby generating major changes for existing technologies, organizations and infrastructures. Renewable energies are intermittent (e.g. solar, wind) with electricity generation cycles that do not follow the demand cycles, energy storage solutions are therefore needed. High temperature proton conductors are currently being used in applications such as the protonic membrane reformer (PMR) where compressed hydrogen is produced directly from steam methane reforming, and in steam electrolysis (PCEC). Both the PMR and PCEC technology has reached a sufficient maturity level to attract industrial interest. To ensure that these technologies can be the choice as a future energy-conversion technology we will in the present project apply the concept of using proton-conducting systems as flexible operating energy-converters. The present project gathers world-leading industry (CoorsTek) and academic institutions (UiO ELCHEM) and (CSIC-ITQ, Spain) to study the effects of cycling operating, especially with respect to thermal management and degradation of the nanostructure of the ceramic proton conducting membranes under intermittent conditions, resembling the periods where a surplus of renewable energy is available. The project will create a computational model of both the PMR and PCEC reactor from which e.g. thermal profiles will be extracted. Results from modelling will be fed to an experimental matrix. A high throughput experimental approach will be to used, which will enable to screen a large range of conditions to sufficiently understand both PMR and PCEC performance and facilitate materials improvements. The project runs for 3 years, trains 1 PhD and 1 research fellow at the University of Oslo, fosters international collaboration with CSIC-ITQ in Spain, aims to establish new intellectual properties in various fields and will disseminate the results of the project in high impact journals and international conferences.
