[What is it about the mass media and biofuels/renewables that they just
can't ever position them as a good news story? Note the negative
message in the headline. As I skim that, I wonder, what's wrong with
biofuels that these buses are no longer going to run on 100%?
However, the real story is actually positive. 31 buses x 100% = 31 bus
fuel equivalents. 320 buses x 30% = 96 bus fuel equivalents or a
threefold INCREASE in biofuel use in their fleet.
I also winced at the last line of the article, which makes it clear that
diesel engines cannot run on biofuel.]
Green buses no longer using 100 per cent biofuel
By CambridgeNews | Posted: February 12, 2015
Green buses on the Busway between Cambridge and Huntingdon and St Ives
no longer use 100 per cent biofuel.
Bus company Stagecoach has decided to switch from running 31 buses on
100 per cent biofuel to having 320 buses which run on 30 per cent
biofuel, as part of a mix of fuels.
Although the biofuel does cost more than other kinds of fuel, the
decision was to change to 30 per cent biofuel was made because older
vehicles were not suitable for 100 per cent biofuel.
The buses have to be modified before they can use biofuel.
This does not affect the Go Whippet buses on the Busway, which have
diesel engines rather than using biofuel.

A different article on presumably the same underlying story.

Apparently, the buses really run on B20 biodiesel blend, and no vehicle
modifications are required.
