Cyclist here in Tokyo with hybrid buses. The hybrid buses start from stop on purely electric power. The diesel engine seems to kick in at speeds above 10kph.

Cyclist here in Tokyo with hybrid buses. The hybrid buses start from stop on purely electric power. The diesel engine seems to kick in at speeds above 10kph. Compared to the large amount of exhaust belched out of diesel only, as cyclist sometime stuck behind a bus, the electric start is a big relief. Can't wait until Japan adopts the same all electric design.

Here in Germany with have quite a few hydrogen powered buses. Examples: (German) https://www.ksta.de/region/rhein-erft/huerth/ab-2019-neue-wasserstoffbusse-fuer-huerth-geplant-29511032 https://www.ksta.de/region/rhein-erft/huerth/ab-2019-neue-wa... But also elsewhere in Europe (here: South Tyrol, Italy): http://www.greenmobility.bz.it/en/projekte/die-bozner-wasserstoffbusse/die-bozner-wasserstoffbusse/ http://www.greenmobility.bz.it/en/projekte/die-bozner-wasser... Nothing but water vapor coming out of them.

  > Water vapor is the most potent greenhouse gas owing to the presence of the hydroxyl bond which strongly absorbs in the infra-red region of the light spectrum. [1] Though I can't tell whether water vapor created at the surface has the same effect as water vapor at altitude.
