On 13 November, our co-founder and CEO Luc Bondaz will present our modular and local solution to transform CO2 into building materials and green fuels at the CDR Innovation & Impact 2025 event, part of the Innovation Booster Carbon Removal program. 📅 13 November at 17:30 📍 Kraftwerk, Zürich The event will feature inspiring keynotes, project pitches from funded Innovation Booster teams, and engaging discussions around today’s biggest carbon removal challenges and innovations. If you’re interested in the latest developments in CDR in Switzerland, we’d love to see you there! ➡️ Register here: https://luma.com/ljux2nyf Innovation Booster Carbon Removal

📢 Proud to share our latest publication: “Above and Beyond the Lab Scale – Creating a kW-Sized AEM Electrolyzer Validated by In-Situ Distribution of Relaxation Times” 👉 https://lnkd.in/d4X2AWBC This work builds directly on our earlier study, “Combinatorial Use of Reference Electrodes and DRT for Disentangling AEM Electrolyzer Losses” 👉 DOI: 10.1021/acs.energyfuels.5c01799. Across both studies, the message is clear: cathodes contribute significantly to the overpotentials in AEM electrolysers and cannot be neglected. By combining advanced diagnostics (reference electrodes + DRT) with system-scale validation, we show how small-scale insights translate into kW-scale engineering. Perhaps, the first study to implement DRT in AEM stacks! At the stack level, this work also demonstrates the importance of novel balance-of-plant (BoP) control techniques: optimising flow, pressure, and thermal management to stabilise operation and minimise dispersion across cells. These engineering strategies are just as critical as materials development, ensuring that device-level learning translates into robust and scalable electrolyser platforms. For me, this is the path forward: diagnose precisely, scale wisely, and never overlook the “silent contributors” that limit performance. #Hydrogen #Electrolysis #AEM #CleanEnergy #ScaleUp #ResearchToReality DeltaSpark, EPFL, Campus Energypolis, ANEMEL, ASTERISK EU, SUSTAINCELL, HyPrAEM Project.

Today is a day to remember. When a Jury consisting of Yushan Yan, Gonzalo Abellán Sáez and Emiliana Fabbri, chaired by Zhengmao Lu gives a decision - 'Thesis accepted without reservation' - it is an achievement. Honored, humbled and gracefully embracing my successful PhD Private Defence - tittled: Advance Electrochemical Characterisation of Low Temperature Membranes and High Temperature Ceramic Electrolysers. A heartfelt thanks to Jan Van herle for giving me the opportunity to develop my skills in this domain. His 'freedom to operate' approach was extremely critical to start, pickup and advance in a new field. The thesis resulted in 5 first author publications, 4 second author publications, 4 conference presentations, 2 conference posters. In addition to academic contributions, 2 patents were also filed - leading to DeltaSpark. Looking forward to next exciting steps, with Luc Bondaz, PhD and DeltaSpark. #epfl #electrolysis

The support for DeltaSpark is only rising! I have been awarded the Bridge Proof of Concept grant to realise the project HyDeCarb! A huge thanks to all our partners and collaborators. A special thanks to Yegor for mentoring us all the way, dissecting the proposal. Your straightforwardness was invaluable. Isabel Casado Harrington, thank you for consistently training Luc and me in the right direction. Furthermore, I extend my gratitude to Maryam Majidian and the EPFL Research Office for rigorous practice. All of this, in parallel with PhD thesis submission, Journal article submissions, Patent applications - rebuttals, Business Training Programs (Innosuisse Entrepreneurship Training, STARTUP CAMPUS Switzerland), as well as EU FCH-JU/EIC project proposal writing, meetings and deliverables, was indeed intense and would not have been possible without the strong support of Luc Bondaz, my Co-Founder. Backed by our mineralisation expert, Rafael Castro-Amoedo, and scientific advisors Dr. Jan Van herle (Electrolyser Expert) and Francois Marechal (Energy System Expert), we have a very strong team. I am looking forward towards the successful implementation of HyDeCarb. #CarbonRemoval #CleanHydrogen #CleanOxygen #Innosuisse #SNSF #EPFL #FCHJU #EIC #BridgePoC
