Which key messages about innovative technologies of the Holst Center should the participants in the lecture your Holstcolleague Dr. Oscar Diaz Morales mediated be arranged?
Manrique: Attendees can expect more details on how thin film and microstructure technologies are transforming the field of electrolyzer technology by reducing the use of expensive exotic materials, lowering manufacturing costs, increasing electrochemical performance, lowering associated stack LCOH costs, and potentially reducing the footprint of electrolyzers, which could be critical for niche applications such as offshore.
The Holst Center is strongly in innovative coatingtechnologies and moves moves towards towards electrolysis 3.0. How important is it, products in these areas new to rethink?
Manrique: At TNO, we have conducted a number of studies on what a future hydrogen-dependent economy would look like, and it is clear that the current cost of hydrogen combined with the current production rate of electrolyzers and the consumption of exotic materials is unsustainable and unachievable. The technology needs to be radically improved to make hydrogen a success and make it affordable and accessible to the wider society, rather than leaving it as a novel technology that is only used in demonstration projects.
The third generation of electrolysis overcomes several technical limitations such as the use of iridium, low lifetime and low predictability of maintenance, PFAS dependency, etc. We are thinking of addressing key technical challenges to create new business models that will allow hydrogen to be used as a molecule in the future green society.
Where see do you see in near future need for optimization with H2-technologies in the near future?
Manrique: Every part of the technology can and should be optimized, as little to no development has taken place in the last 25 years. However, we see the biggest opportunities in the membrane electrode assemblies, in switching from membrane-based to electrode-based catalysts, in changing the way the bipolar plate architecture works, in optimizing components such as PTLs to promote better kinetics, etc.
Emilio, heartfelt thanks for this interview.
