Germany launches world’s first hydrogen trains in service – pv magazine International


Germany has launched the world’s first operational hydrogen trains and US researchers have presented a new design for a tubular PEM fuel cell. ABB and Hydrogen Optimized, meanwhile, expanded their strategic ties and Slovakia moved forward with a major gas blending pilot project.

Landesnahverkehrsgesellschaft Niedersachsen (LNVG) began operating 14 hydrogen trains, as part of its project to gradually replace diesel locomotives on a 100 km (60 km) stretch of track in northwestern Germany. Alstom’s Coradia iLint trains are “now used on the first 100% hydrogen train line, in passenger service”, said the French industrial group. The train can run all day on a single tank of hydrogen, before being refueled overnight at Linde’s hydrogen filling station. The trains are equipped with Cummins fuel cell systems. “Cummins will supply 54 additional fuel cell systems to Alstom for an order of 27 Coradia iLint trains to be delivered in the Frankfurt metropolitan area,” the US company said. They carried out trials for almost two years, in addition to Coradia iLint tests in Austria, the Netherlands, Poland and Sweden.

University of Connecticut Researchers have developed a novel polymer electrolyte membrane (PEM) tubular fuel cell design with a replaceable internal electrode and electrolyte. The patent-pending conceptual design could have nearly twice the energy density of other tubular PEM fuel cells. Planar fuel cells use sandwich stacks of rectangular graphite or metal flow field plates, which are about 80% of their weight and 40% of their cost. UConn’s design uses a single tube-shaped flow field that cuts its weight in half and requires less precious metals. The team said the new design also addresses compression issues, uneven current distribution, reactive gas transport issues, excess water removal, and manufacturing challenges associated with the design of planar fuel cells. The concept is still being discovered and is receiving funding from I-Corps and the National Science Foundation (NSF) Partnership for Innovation (PFI).

ABB and Hydrogen Optimized (HOI) have signed a new hydrogen-focused agreement. The deal includes an investment by ABB in Key DH Technologies, HOI’s parent company, to accelerate the production of green hydrogen. “The companies will leverage their respective capabilities and resources to rapidly commercialize HOI’s patented RuggedCell high-power water electrolysis technology,” the Canadian company wrote. HOI expects its high-power alkaline technology to be deployed in large-scale hydrogen plants in combination with ABB’s high-power rectifiers. The companies said they expect installations ranging from hundreds of megawatts to several gigawatts. “Other available technologies now operate at low current, which limits the size of each plant – typically 20 MW or less, and in many cases considerably less. This is the high power architecture of the RuggedCell electrolyser. which allows for a single large-scale 100MW and ultimately gigawatt-scale facility,” Hydrogen Optimized said. photo magazine. The RuggedCell is iridium/platinum free.

SPP-D said that its H2Pilot project in Blatná na Ostrove, Slovakia, shows that hydrogen can be safely distributed in existing gas networks. “From a technical point of view, the mixing device works reliably, dosing continuously and in the required volumes,” said SPP-D press officer Milan Vanga. photo magazine. Chromatographic measurements carried out on a weekly basis would have demonstrated the homogeneity of the distributed mixture, approximately 10% in all parts of the municipal network. “Inspection of the highest risk appliances – 32 oldest and/or atmospheric boilers and 25 stoves – after one month of use with a 10% mixture showed positive results in all cases,” Vanga said. , with reference to ignition, flame stability and functionality. . The gas distributor said customers reported no relevant issues. The SPP-D launched the project on June 15.

First hydrogen announced that its two hydrogen demonstration vans have completed initial commissioning tests. This “step allows vehicles to be tested under mixed road and driving conditions and confirm performance prior to First Hydrogen’s actual operational trials with major fleet operators in early 2023,” said First Hydrogen.

Plug hole signed a supply agreement with Amazon to supply liquid green hydrogen starting in 2025. “Amazon and Plug have signed an agreement for Plug to supply 10,950 tons per year of liquid green hydrogen to power the operations of Amazon”, wrote Plug hole. “Using Plug’s electrolysers, liquefaction capabilities and cryogenic tankers, Plug will deliver hydrogen to Amazon beginning January 1, 2025.”

Namibian Prime Minister Saara Kuugongelwa-Amadhila said last week that green hydrogen is poised to become a central pillar of the country’s economic and development agenda. The government selected several green hydrogen pilot projects at a recent two-day conference. Four of them will receive NAD 500 million (A$4.3 million) in German-backed funding.

Germany has approved €223 million (A$322 million) co-funding for eight hydrogen projects around its largest port, Hamburg. The German government has selected a total of 62 major industrial projects in Germany for federal and state funding.

Foton Mobility and public transport systems have announcement the arrival of the first two hydrogen fuel cell buses in Australia. Foton has manufactured and delivered over 1,100 units, including 450 hydrogen buses used in the 2022 Beijing Winter Olympics. SinoHytec and Toyota jointly developed the fuel cell systems for the buses.
