A recording of the workshop will be uploaded later on the workshop page. 01:08:38 Rudi Carbonez, Anglo Belgian Corporation: Did you also investigate internal combustion engines running on Hydrogen ? We have proven solutions especially for freight mainline locomotives. 01:13:52 Paul Tobback (TUC RAIL / Infrabel): >100km routes: does this mean >50km antenna lines with a terminal station where the trains need to return ? In these cases, there is mostly some time to refuel the trains again. So it would mean >100km even for these antenna lines on the condition of an optimal location of the refueling station(s), depending on the network and operational practice. 01:19:21 Andrew Kluth, RSSB: Professor David Cebon - Director of the Centre for Sustainable Road Freight and the Cambridge Vehicle Dynamics Consortium said in a webinar on alternative fuels for UK freight yesterday that the case for hydrogen is poor. His reasons are that (1) the energy demand to produce green hydrogen would demand a significant additional renewable generation facilities to support the generation and (2) CCS is not proven at any significant scale, so blue hydrogen is not viable in carbon terms 01:19:39 Laurent NICOD/ALSTOM: Are the hypothesis and detailed calculations of LCC of the Roland Berger study available for verifications ? macro final conclusions are given, but many stakeolders would like to better understand what is behind. 01:20:13 Andrew Kluth, RSSB: On length-constrained networks like GB, putting in a fuel car at the expense of a revenue earning car may not be profitable 01:23:32 Christian Klotz (DZSF): How About the economical effectiveness of internal combustion vs. fuel cell? Is the internal combustion engine solution cheaper in Service and how is the difference in effectiveness? 01:24:13 Laurent NICOD/ALSTOM: do you have links with countries trying to implement low CO2 electricity production? France announced 600 000 tons H2/year on 2028, but new nuclaer plant proposed by EDF is just Under discussions and offshore windmills projects are blocked by ecologist associations or fishermans... 01:31:08 Bart Biebuyck FCH-JU: Dear Laurent, the link to the study is https://www.fch.europa.eu/publications/use-fuel-cells-and-hydrogen-railway-environment 01:32:46 Gerald Olde Monnikhof (ProRail): Do you store the H2 at the filling stations liquid or under pressure? And is it locally produced with electrolisers or in some cases transported by truck or pipeline? 01:33:13 Takashi Yoneyama_RTRI_JP: >Isabel What are the important differences between a hydrogen station for rail and one for FCVs? What are the difficulties in developing a hydrogen station for rail? 01:36:17 Bart Van der Spiegel - Infrabel: This study will be presented by TML next week on the battery train workshop. 01:38:37 Martina Zeiner, Graz University of Technology: In regard to the import of green hydrogen, to what extent do you have a look at the environmental impact considering the transport chain? Is is negligible? 01:39:06 Martina Zeiner, Graz University of Technology: In regard to the import of green hydrogen, to what extent do you have a look at the environmental impact considering the transport chain? Is it negligible? 01:42:27 Andrew Kluth, RSSB: A challenge in assuming zero emissions transport of fuels is about when this will happen? 01:45:57 Isabel Francois WaterstofNet: I don't see fundamental differences between a hydrogen station for rail and FCV's. The advantage is that the offtake is very predictable, which makes it in principle easier and more econmic to operate a station for trains. technically the principles are similar. 01:49:36 Isabel Francois WaterstofNet: Fuel transport with zero emission ships might not be so far away; in Japan they are developing a first ship for liquid hydrogen. But zero emission fuel can also be green methanol (with recycled CO2 or CO2 from air) or green ammonia. First ships on methanol are already operational. 02:04:24 Paul Tobback (TUC RAIL / Infrabel): Hi Isabelle, don't forget H2 in Charleroi, but we can discuss it later. I don't see passenger trains running on H2 in this location, even Charleroi-Couvin being the longest non electrified route in Belgium, but due to the already presence of H2 in the area, it can be economically feasible to supply work trains here, certainly if synergies with other consumers is possible. 02:06:26 Rishi Ravindran: What is the timescale for future H2 Business case? 02:06:57 Kenta TAKASHINA(JR EAST): What is the mechanism that makes the 800 km range possible? 02:07:13 Rishi Ravindran: Thank you. And is the power being generated locally or via Grid? 02:08:01 Kenta TAKASHINA(JR EAST): Thank you 02:11:26 Philippe Stefanos, UIC: Dear speakers and participants, please don't mind me to skip a question or anticipating the switch to another slide :) For people who joined late, please click on your name to rename as "Surname Name, Company" 02:16:46 Laurent NICOD/ALSTOM: What was the aim of test? technical only? or LCC included ? 02:18:47 Takashi Yoneyama_RTRI_JP: >Michael What were the difficulties in getting the first fuel cell train to run on the main line? How did you get an admission in Germany? What were some of the difficulties in getting fuel cell trains to run in other countries? 02:20:34 Laurent NICOD/ALSTOM: What was the budget of this test ? 02:21:33 Gea Kolk Movares: How is it possible to test the feasibility of the time table with 40 km/h? 02:22:24 Vadillo, Inés ADIF: Who provide the refulling sistema? 02:23:32 Takashi Yoneyama_RTRI_JP: Is the hydrogen refueling vehicle originally designed to refuel FCVs? 02:25:27 Per Corshammar: Noice H2 engine comapeed to diesel noice? 02:26:49 Natalie Gravett: Thank you - I would love to hear more about the testing report as well please 02:28:45 Philippe Stefanos, UIC: Sorry! 02:31:24 Gerald Olde Monnikhof (ProRail): Do you in the German operation produce the H2 local by electrolisers or is it brought on site by trucks? 02:32:04 Takashi Yoneyama_RTRI_JP: How did you verify the safety of driving in tunnels? 02:35:00 Rishi Ravindran: How heavy is the train that did +1000km? 02:38:17 Paul Tobback (TUC RAIL / Infrabel): Would there be a possibility to rebuilt existing engins for maintenance with the FC-modules & storage tank modules or should this better be done independently starting from scratch on each engine ? 02:39:27 Peter Klamo, ZSSK (Slovakia): what was average price for hydroden fuel during pilot testing phase? I mean euro/kg for 350 bar hydrogen used in mobile dispensers 02:39:45 Branco Schipper (SGS Search): In the refuelling station, will hydrogen ne stored under pressure or in liquid form? What are the main considerations choosing between liquid and gaseous storage? 02:40:13 Paul Tobback (TUC RAIL / Infrabel): What's the surface in m² and what part is foreseen fore local electrolysis ? Would 400m² be sufficient if only fueling installations are needed ? 02:41:07 Takashi Yoneyama_RTRI_JP: Compared to the diesel Lint, was the vehicle body reinforced to install the heavy hydrogen cylinders and fuel cells on the roof? 02:41:17 Dr. Alkhalil Senan - DB E&C USA: How is the safty by having H2 tanks on roof? 02:42:18 Alain SCHERRER (UIC-Rolling Stock Energie): what is the impact on the number of seets? 02:42:28 Takamasa Yamada,Railway Technical Research Institute, JAPAN: When the train is running, FC is running at full power or lower?, changing at speed? 02:44:42 Gea Kolk Movares: Is the Safety Study available? 02:48:22 Paul Tobback (TUC RAIL / Infrabel): I calculated something around 2500m² for Bremervörde 02:50:07 Alain SCHERRER (UIC-Rolling Stock Energie): so no double-decker trains? 02:50:35 Jose Cadilha, CP: special measures should be foreseen in the intake air for HVAC system in the room near the H2 tank ? 02:51:59 Takashi Yoneyama_RTRI_JP: Is there an emergency external charging circuit in case the fuel cell stops working? 02:53:40 Alain SCHERRER (UIC-Rolling Stock Energie): is it possible to agree on a common way to measure efficiency of the enrgy management system? 02:57:34 Glenn ESG Matters: Thank you. Good info well presented. 02:57:42 Holger Dittus (DLR): Alain - you could apply EN50591 for that purpose 02:59:45 Jean-Baptiste CHHUOR: How about the ISA tasks? 03:01:19 Dr Inara Watson, LSBU: It is possible to share slides of this event? 03:02:47 Fiona Twisse, Ricardo Energy & Env.: Thank you 03:02:53 Holger Dittus (DLR): thank you, also to the presenters - byebye 03:03:07 Chamaret Andre (FRANCE / SNCF VOYAGEURS): Many thanks, bye 03:03:27 Jorge Juárez: Thank you 03:03:36 Tânia Ramos (CP): Thank you very much!
