'Chaos and massive disruptions' | World's largest hydrogen train fleet suffering teething problems in Germany
All 27 trains — ordered at a cost of €500m — were due to be operational in December, but manufacturing delays and technical faults have caused huge problems for passengers
Hydrogen: hype, hope and the hard truths around its role in the energy transition
But due to production delays, only six had been delivered by that date, and only two went into service on 11 December on the mountainous Taunus railway line — the first of four routes due to run hydrogen fuel-cell trains instead of diesel locomotives.
Ulrich Krebs, a local politician and chairman of the supervisory board of the RMV, described the situation as “completely unacceptable”.
“As with any innovation process, the Coradia iLint is now entering a phase of stabilisation of the operation process, as well as in a phase of reliability increase of the equipment, in particular the most innovative equipment,” an Alstom spokesperson said.
“The phases we are entering now are normal and necessary for the implementation of innovative solutions: innovation is the result of a long cycle during which all stakeholders are able to improve the processes and the operation.
“We will not make any further comment and are focusing all our efforts on the stabilisation of our operations and the increase in train reliability.”
The entire Taunus railway line was closed from 13 to 29 January, and again from 10 February, and is not scheduled to reopen until 26 February, with buses acting as a rail replacement service.
By the time the Taunus line was closed in January, a total of 15 of the 27 trains had arrived, according to RMV, and now the full fleet will not be delivered until June, according to train manufacturer Alstom, citing supply chain problems caused by both Covid and the Ukraine war.
The four train lines, which are considered difficult to electrify, will use hydrogen produced as a chemical industry by-product at nearby Höchst Industrial Park.
According to RMV, this production is powered by the local power grid, which gets about 50% of electricity comes from renewable energy sources. The price being paid by RMV for this hydrogen is “well below market price currently quoted elsewhere”.
The hydrogen trains are currently operating between Frankfurt, Bad Homburg and Brand-Oberndorf, with the three other routes due to get their fuel-cell locomotives up and running later this year.
