Road vehicles

• The Hague is the first Dutch city with a taxi fleet running on H₂ (Toyota Mirai, specifically) (2020-04).
• As part of the European Commission's JIVE project, a dozen H₂ buses for Bolzano, Italy. The buses are manufactured by Solaris and have a range of 350 km on a single tank of LH2 (2019-07).
• FlixMobility (parent company of Flixbus) plans to operate fuel cell coaches on long-distance routes (2019-11). This as part of the research project HyFleet together with its partners Freudenberg Fuel Cell e-Power Systems and ZF Friedrichshafen AG, overseen by the German Federal Ministry of Transport and Digital Infrastructure, with start of commercial operation slated for 2024. More sources: 1.
• The first H₂-powered double decker buses have started operation in Aberdeen, UK (2021-02). The project was funded by the city, the EU, and the Scottish government, for 15 buses costing about 0.5 million GBP apiece.
• Gross-Gerau district in Germany plans for 80 H₂-powered buses in its fleet by 2028. I wonder how many buses the city operates in total.
• Hyundai plans to sell 1600 heavy trucks in Europe, and cooperates with Hydrospider for the H₂ supply.

Trains

• San Bernardino county in California awarded a contract for a H₂-powered train in 2019 to Stadler to run by 2024. I thought southern California was densely populated - why not electrify the tracks? Fuel cells are better than dirty and loud diesel locomotives, I suppose. This is the first H₂ fuel cell train in the US, and many other places in the US are quite sparsely populated, so let's hope it is followed by more.

Ships

• The Norwegian Public Roads Administration is to operate the world's first H₂-powered ferry connecting its fjords. The ship is built by Norled and has a carrying capacity 299 passengers and 80 cars. Details on its power train have not been forthcoming.
• A river vessel on the Rhone river with a powertrain built by ABB, supported by the European Commission's Fuel Cells and Hydrogen Joint Undertaking (FCH JU) and in cooperation with other parties.
• The first H₂-powered ferry in the US has started serving San Franscisco Bay. It takes 75 passengers, has three fuel cell stacks, and a top speed of 20 knots. The project was awarded a $3 million grant by the California Air Resources Board. For reference, there are about 1000 passenger ferrys operating in the United States.
• The world's first LH2 carrier has been put into service ferrying grey H₂ (meaning H₂ produced from fossil sources) from Australia to markets in Japan. The vessel was built by Kawasaki Heavy Industries and comes equipped with a tank able to hold 1250 m³ of liquified H₂ at a temperature of -253℃ (20 K).
