"""This is the first time a hydrogen bus has traversed the Hong Kong Island and New Territories route.
Richard Hall, the managing director of Citybus, stated that they will no longer purchase diesel buses but replace them with hydrogen buses on a one-for-one basis.
The goal is to use hydrogen or electric buses in its entire fleet by 2045.

Victoria warned against ‘very inefficient’ hydrogen buses after trial announced

Cambridge professor says grey hydrogen buses are expensive, ‘destructive’ and not a true zero-emissions solution
To put it politely, this is greenwashing. To put it impolitely, calling these busses "green" or "zero emission" is a whopper of a lie.
If you read about these busses at the company's website, they're very careful not to reveal the source ("colour") of the hydrogen. https://www.transitsystems.com.au/hydrogen-bus-new
They're using grey hydrogen. "Grey" Hydrogen is not Zero Emission. It's made by extracting hydrogen from fossil gas, and there's no effort put into capturing the carbon during the processing.
These busses are just as polluting — considerably more polluting when you look at inefficiencies and losses due to processing, transport, and storage — as a bus powered by any other fossil fuel, but the pollution happens at a processing plant far away. The pollution is out of sight; out of mind.
