Shanghai is set to overhaul its bus and taxi services, completely switching to new energy vehicles (NEVs) by the end of 2027, according to the city's latest work plan update concerning transportation infrastructure and equipment.From 2024 to 2027, Shanghai
Does this basically catch up with what London already did? Or is it a further advancement beyond it?

I'm not strictly clear on what a "New Energy Vehicle" (NEV) is in China's lingo, and whether it refers to low emissions or ZERO emissions vehicles, which are quite different things. Both are good obviously but understanding which is which is pretty necessary to compare with good efforts occurring in other cities.
It's a combination of hydrogen and battery powered from what I've read.
So the term NEV always applies to zero emissions vehicles?
I'm just trying to work out what the comparable terms are across countries because obviously we're all using different terms in different country initiatives and working out specifically what those terms mean is essential to comparing them.
I'm not just asking others to do my work for me, I can't really find specifics on this, probably need to search in chinese language to get into the details.
I'm not really sure it's a common term to be honest. I agree that lack of standardized terminology makes comparisons tricky.
Is hydrogen viable? Last I heard the reactivity of hydrogen made it difficult to use at scale. I remember there was some talk about using ammonia as a more stable form but I had heard that had efficency problems
It looks like China's been using hydrogen cells in buses for a while now. I haven't looked at the details of the specific approach they use though.
I remember we were big on hydrogen for a while but I rember it was hard to store and and that made it expensive. Probbaly china just went through the process of actually investing in infrastructure which we would never do
Yeah, it's the same thing with rail, the argument is always that the upfront investment is just too high and it's not worth it.
I wouldn’t be surprised if busses are one of the use cases where it makes more sense. Like, leaks matter less in a vehicle that spends little to no time sitting around.
