I USA tycks man i allafall ha framdrift på vätgas. Jag läste om att en del tågbolag räknar med att ha ställt om helt till vätgasdrift inom några år. Förmodligen är det för att de inte är statligt subventionerade utan ser att det finns en företagsekonomisk och konkurrensfördel med fossilfria transporter.
Skall Europa halka efter med miljöfarlig kinesisk batteriteknik?
Det är en enorm skillnad mellan godståg i USA och persontåg i Europa. Till att börja med är
enbart 1 procent av USA:s järnvägar elektrifierade. Motsvarande andelar för Europa, Kina och Indien är 60, 72 respektive 83 procent. Vidare färdas godståg mycket längre än persontåg. Därför skiljer sig behoven så mycket:

Satsningen på bränslecelldrivna tåg handlade egentligen om att pumpa in skattepengar i gasleverantören Linde. Stadlers Flirt Akku har en räckvidd på
150 km:
Railway Gazette International skrev:The first of the Stadler Flirt Akku battery-electric multiple-units ordered by Schleswig-Holstein transport authority NAH.SH have entered revenue service with operator Erixx Holstein.
[...]
Regular BEMU services began on route RB76 between Kiel and Kiel-Oppendorf on October 1, followed by Kiel – Lübeck – Lüneburg from October 22. BEMUs are to be introduced on the Büsum – Heide route from the December timetable change, and all 55 units are scheduled to enter service by mid-2024. Erixx will operate 26 of them.
[...]
The batteries are charged when the trains are operating on sections of route with 15 kV 16·7 Hz electrification and at stations fitted with overhead catenary. DB Netz is spending €40m to install electrification ‘islands’ totalling 11 km on selected routes by December, which will reduce the longest unelectrified gaps to less than 80 km.
Således finns det inget behov av bränslecelldrivna tåg i Europa. Den tyska industrin kan subventioneras direkt istället för att parasitera på kollektivtrafiken.

just erkänt att bränslecellsdrivna tåg är meningslösa i Europa, men diverse politiker insisterar ändå. Det är
samma sak med bussar:
Liverpool Echo skrev:But while it was all smiles on launch day, the hydrogen buses have been beset by problems since that point, spending large portions of time entirely off the road. You may have seen them parked up outside conferences and events, but chances are, you probably haven't seen them carrying passengers anytime recently. As things stand, all twenty are being stored at depots around the region.
[...]
At present, the buses are undergoing battery refit and software upgrades, which the CA points out are happening at 'zero cost' to the authority or the local taxpayer.
[...]
It appears clear now that when it comes to the future of buses in the city region, the emphasis will be on electric rather than hydrogen. Just this year the CA has ordered more than 100 fully electric buses. So was hydrogen a failed experiment? Well Mayor Rotheram's opponents certainly think so.
I slutändan fungerar bränslecellsdrivna tåg som batterielektriska tåg med ett extra steg. Det behövs ett batteri i alla fall, och det kommer
naturligtvis från Kina:
Financial Times skrev:“They have a wrong design . . . they have a wrong process . . . and they have the wrong equipment. How can they scale up?” the chief executive of CATL told Nicolai Tangen, the head of Norway’s $1.8tn oil fund. “So almost all mistakes together.”
The bleak assessment from the world’s biggest electric vehicle battery manufacturer captures the scale of the failure for the industries behind the critical technology for Europe’s decarbonisation, leaving governments, companies and investors at a loss as to how to recraft the continent’s strategy to compete with China.
“How are we not taking this more seriously? The European car industry is the heartland of European industry’s supposed prowess,” said one long-standing investor in Northvolt after the collapse into US bankruptcy last week of Europe’s biggest battery hope. “The depth of the crisis for the European car industry is almost unlimited. It’s incredibly grim.”
