After the partners of the PC3 met and exchanged on the topic of ammonia ships online in 2021, we were able to hold an excellent workshop in wonderful Duisburg this year! The host was the ZBT The Hydrogen and Fuel Cell Centre — not only the main technology provider in our alliance, but also responsible for the management of strategy and technology in the CAMPFIRE Open Innovation Management. The ZBT was very much supported by the DST — Entwicklungszentrum für Schiffstechnik und Transportsysteme e. V., also located in Duisburg. After a welcome to the approximately 50 participants by the managing director of the ZBT, Dr. Peter Beckhaus, Mic Steffen (ZBT) and Benjamin Friedhoff (DST) led through the exciting program. As a kick-off, André Klein, MARSAS, presented on the existing challenges for crews and emergency services in the event of an ammonia disaster, followed by a presentation by Stefan Große Allermann, IKET, on the required approval procedures and safety measures using the example of ammonia refrigeration plants. Highly interesting was the contribution of Steffan Bölker, GDWS on the approval of inland vessels with alternative fuels — among other things a very important and current topic for the partners of the CAMPFIRE product line CF08 Ammonia Inland Vessel. A highlight was the presentation of our guest from Greece, Konstantinos Voutzoulidis, ABS Hellenic, from the NH3CRAFT project with a presentation on the safe and efficient storage of ammonia on board ships. The sporting program continued with contributions from the CAMPFIRE Consortium. Martin Stoltmann, Tamsen Maritime, and Dr. Thomas Painter, IKEM, presented on the certification of inland vessels with NH3 propulsion, followed by Dr. Lena Engelmeier, ZBT, with a presentation on ammonia crackers in the overall engine system, and Dr. Dana Meißner, ISV, on the explosion limits of ammonia. Other highlights included a presentation by our guest Kevin Rouwenhorst, Proton Venture from the Netherlands, on ammonia storage and safety aspects, and a presentation by Hiroyuki Inoue, Mitsui & Co. Germany GmbH, on Mitsui & Co.‘s gray, blue and green ammonia activities. Our first workshop day ended with a very interesting tour at DST, followed by a social evening of all participants. The following day was dedicated to a World Café for the joint discussion of innovative solutions and new project ideas. Jens Wartmann, ZBT, led through the café on the topics of approval, ammonia infrastructure and logistics, ammonia safety and cracker engine propulsion system. Many thanks to all participants — it was a great event!
