World's First Hydrogen Double Deckers Arrive In Aberdeen (theengineer.co.uk) 112

Posted by BeauHD from the first-of-its-kind dept.
The world's first hydrogen-powered double decker bus has been revealed in Aberdeen, a move that demonstrates the city's commitment to tackling air pollution and implementation of its Net Zero Vision. The Engineer reports: Hydrogen double deckers will now be driven around the city for several weeks during a period of final testing along with training for drivers. The UK's first hydrogen production and bus refueling station opened in Aberdeen in 2015 as part of a green transport demonstration project. The Aberdeen City Council-led project tested the economic and environmental benefits of hydrogen transport technologies and aims to drive the development of hydrogen technologies.

In a statement, Aberdeen City Council Co-Leader Councillor Jenny Laing said: "We are very proud to bring the world's first hydrogen-powered double-decker buses to Aberdeen as it shows the city continues to be at the forefront of developing green technologies." "The roll out of the new double-decker buses will help to cement Aberdeen's position as an entrepreneurial and technological leader as the new buses come with even more advanced technology which pushes established hydrogen boundaries and greatly assists us in tackling air pollution in the city." First Aberdeen is to run the 15 buses along one of its most popular service routes, with the vehicles expected to be in service in November, 2020.

      I think the "likely covers" is the dangerous part of your assumptions. For a bus that runs many hours a day, perhaps a daily stop for refueling works better than charging a battery.
      Another thing to consider is that Aberdeen is quite far to the North, so maybe the efficiency factors are better suited for one source than the other.

      Now I've offered my unsubstantiated opinion, I'll have a quick look at TFA. With some luck, it's not even the same Aberdeen I was thinking about.

          Are you dividing the fleet mileage by the number of buses? There are plenty of buses that work only during rush hour, and they reduce the average a lot. Buses in service all day will have longer mileage. Of course some may be rotated during the day, but this complicates logistics and depends on depots being in just the right spots.

    It's a scam. There are three ways to make hydrogen:
    1. From natural gas. It's much more efficient and easier to just use the gas directly.
    2. Through electrolysis. It's INSANELY MUCH more efficient and easier to just use the electricity directly.
    3. Through thermolysis. When using direct sunlight to do so, this MIGHT equal the efficiency of cars powered by PV-electricity. However, there's just one experimental plant that does this and it relies on direct sunlight (so no clouds).

    All in all, hydrogen powered whatever is a scam, mostly fueled by misguided subsidies. It's wildly inefficient compared to any alternative in any scenario and will always be much more expensive than those alternatives (which is why it is an attractive scam to invest in).

It's just wasteful at best.
