00:03:44 Marc Boudier: still no audio sorry 00:04:14 Philippe Noisette (Hitachi Energy): I have a very good audio 00:04:33 Marc Boudier: ok solved 00:04:50 Robin Schipper (ProRail): i had to test my speakers and then it worked 00:05:48 fedor.tenharve: co host Fedor nice that the audio is ok 00:10:40 Infrabel - Bart Van der Spiegel: Please include full name and company name in your ID. You can click on more and rename. 00:10:41 UIC-Philippe Stefanos: Dear all, Please think about renaming as Company-Name Surname using the participants' list and clicking "rename" on your name 00:15:00 Infrabel - Bart Van der Spiegel: You can introduce questions in the chat. 00:17:32 UIC-Philippe Stefanos: There will also be a discussion session after each presentation. 00:17:48 DB USA - Dr. Senan Alkhalil: Refer to slide no. 9. How about Hydrogen for energy storage? Thanks 00:20:31 Infrabel - Bart Van der Spiegel: Dr. Alkchahil, Hydrogen is more a longer period energy carrier than really a short time storage. 00:21:58 Paul TOBBACK - TUC RAIL: What about Carbon based Power Capacitors ? 00:22:44 DB USA - Dr. Senan Alkhalil: Thanks. I misunderstood the diagram. Since it shows (Y-axis) short to long storage time. 00:23:58 Network Rail, Blewitt: Is the future long term success of Lithium batteries going to relay on the ability to recycle the Lithium batteries cost effectively? Is the the recycling process expected to become more effective than is currently possible? 00:24:30 Andreas Fuchs SBB Swiss Federal Railways: Re Hydrogen: https://grist.org/wp-content/uploads/2006/08/e13.pdf 00:25:44 Niels Thougård Pedersen (Trailc): Will slides be available or distributed afterwards? 00:25:55 UIC-Philippe Stefanos: It will, yes 00:27:19 EDFC - Jean-Baptiste CHHUOR: What standard will be applicable for batteries development? 00:33:41 EDFC - Jean-Baptiste CHHUOR: Thanks you 00:34:44 DB Energie | Jean Z. Chebou: What about live cycle from producing until recycling? 00:35:14 Paul TOBBACK - TUC RAIL: Thanks Johan, I indeed meant hybrid power capacitors, so with battery functions 00:36:25 Armando Ansón CAF: In the figures you mentioned before, the energy densities of the tesla batteries refer to cell level or to pack level? Apart from that regarding that 25% safety reserve, You refer to the SOH at EOL? Which is the usable range? 00:37:44 InnoEnergy - Johan Söderbom: It is on pack level. 25% safety is range e.g. SOC 00:38:09 Andreas Fuchs SBB Swiss Federal Railways: Recycling (german, sorry): https://www.empa.ch/web/s604/kyburz-batterierecycling 00:41:21 Armando Ansón CAF: Having a look at the Tesla model 3 specs, the battery has a usable capacity of 77,2kWh with 480kg weight, it leads to around 6,2Kg/kWh. Are you talking about different cells/battery? 00:41:26 Infrabel - Bart Van der Spiegel: Mr. Söderbom, will Europe be able to avoid a Chinese domination of battery market? As shown on your slide 22 it's not only the production of batteries, but also the contruction of components and the raw materials. 00:42:08 Armando Ansón CAF: Which is the expected lifetime in full equivalent cycles working on that 4,5h driving/45min charging schedule? 00:43:56 InnoEnergy - Johan Söderbom: Part of the value chain is very hard to establish in the short term, such as raw materials were there are long lead times. In cell manufacturing Europe has the largest Investments in the world right now so there I´m sure we will be good 00:52:36 InnoEnergy - Johan Söderbom: reg cycles: practice shows that a well controlled (temperature, SOC, power takeoff etc,) battery will last a lot longer than expected. so without going into exact specs of the batteries the OEMs surly see the BEV as competetive on a TOC perspective. (lower fuel cost, less maintenance etc) 01:01:45 Infrabel - Louise Meurs: For the Dutch railways: The 2 identified options for storage are VRF and LTO batteries. Why these, and why are flywheels and ultracapacitors not considered? 01:08:05 Infrabel - Bart Van der Spiegel: Only using 40%-60% range in normal operation is very small range. What do other speakers consider? 01:08:28 Armando Ansón CAF: Seeing the degradation of batteries being fast charged (high C-Rates) I really doubt they will last longer than expected, as usually the life is given at lower rates. Anyway a very interesting presentation, thanks! 01:12:07 Hitachi Energy - Philippe Noisette: What DC appaeratus/protections are applied for 1650Vdc? 3.3kV devices? 01:12:24 Martijn Wolf (Ricardo Rail): To Louise: main reasons are combination of capacity, space occupancy and (charge/discharge cycles) 01:13:04 RTRI Uzuka: In Japan, DC traction is almos equal to 1.5 kV. 01:14:13 Hitachi Energy - Philippe Noisette: Yes, 1.5kV is standard but I'm doubting 1.5kV devices can safely being applied to 1650Vdc 01:14:58 RTRI Uzuka: Correct. Some application use 3.3 kV devices, old ones used 1.7 kV ones. 01:18:47 Infrabel - Louise Meurs: I don't see the presentation 01:21:21 Hitachi Energy - Philippe Noisette: This new ESS application (hundred's MW's & kV's) be interesting for participants: https://www.hitachiabb-powergrids.com/offering/product-and-system/facts/statcom/svc-light-enhanced 01:28:02 ProRail - Robin Schipper: is the LCA of ESS available? and can it be shared? 01:28:34 Hitachi Energy - Philippe Noisette: Slide 9: LTnO is missing (no thermal run-away) 01:32:31 Hitachi Energy - Philippe Noisette: Slide 17: Who did supplied the insulated DC//DC? 01:33:13 RTRI - Takeshi Konishi: To Armando-san, thank you for your question. As you mentioned, C-rates should be take into consideration. But SOC control is also important for the long duration. Many Japanese railway install TESSs for the emergent power supply, so the low range of SOC is also impossible for the nomal operation. 01:48:09 Andreas Fuchs SBB Swiss Federal Railways: Does this mean that you have batteries on board of the trains? 01:53:29 Andreas Fuchs SBB Swiss Federal Railways: Thank you! 01:54:01 JR East - Shota Nomiyama: Normally, trains such as ACCUM have batteries beneath the train. 01:54:57 ProRail - Robin Schipper: manny thanks for al the presentors and verry interesting presentations. 01:57:08 UIC-Philippe Stefanos: WCRR = World congress on railway research 01:57:47 Paul TOBBACK - TUC RAIL: general question: is it foreseen to use the on board batteries also as an energy source, like the bi-directional TESS ? 01:59:57 Hitachi Energy - Philippe Noisette: https://chargeoninnovation.com/ 02:00:28 RTRI Uzuka: Fuel cells are purely energy source. In Japan, fuel cells cannot stand alone without secondary batteries (probably Li-ion). 02:02:20 RTRI Uzuka: In China, some taxis use Li-ion batteries just as a power source, they are easy to exchange, I guess. 02:02:50 Chamaret Andre (FRANCE / SNCF VOYAGEURS): @Paul TOBBACK: Study has been realized for mass-transit train on 1.5KV DC in SNCF Voyageurs, sure it's very interesting 02:03:37 Urban Johansson (Trafikverket): Thanks for a very interesting meeting! :-) 02:03:38 RTRI Uzuka: Thank you very much to organize such an interesting session ! 02:03:51 JR East-Nakagawa: Merci! 02:04:00 Chamaret Andre (FRANCE / SNCF VOYAGEURS): Thank you for workshop 02:04:03 DB Energie GmbH | Kai Wittig: Thank you!!!
