Because they're run by an idiot?

Is there a viable alternative in the nearish future though? Chris Goodall plumps for loads of wind and PV generating Hydrogen for storage and running hard to electrify applications as a good option, not least because it can use a lot of the existing infrastructure and not require a huge change in everyday lifestyle.

Not having read the piece (not fond of hydrogen when its energy intensive conversion compared to solar simplicity).
How do site vehicles (all those JCB's et al) at a housing estate get & stay fuelled, does this mean hydrogen bulk storage (presumably guarded based on value & the jitters) at all new estate builds?

Don't know really, BOC and Air Products are well used to transporting lots of cylinders of fuel gasses around though, maybe it could be something similar?

So to make an allegedly green impact, the BOC delivery wagons would have to run on renewables too I guess or else it eats into the result & inflates cynicism regarding how green it actually is.

Sure why not burn some of the H2 in the delivery vehicles? After all that's why we are delivering the H2 in the first place. I guess there are always going to be some vehicles that are just too hard to electrify for one reason or another, if they could burn H2 it wouldn't be a bad option IMHO. Or perhaps if we could reduce the diesel consumption by say 90% the remaining 10% wouldn't be a problem.

I'm envisioning dump truck style intermediary fuel delivery for refuelling the other plant equipment on large building sites during machinery downtime?

Battery electric. It already exists, it's a known technology and requires no new infrastructure. Its round-trip efficiency is 3x orders of magnitude better than Hydrogen fuel cells, produces no tailpipe emissions and, if the plant owner wishes, they can generate their own fuel on-site.

Hmm, "perhaps" whilst building a new estate (for instance) they should install some fast charger bays for their EV construction vehicles which are then mothballed with the connections ready for a corporate buyer.
Muscling Hydrogen into the place of petrol & diesel with "only we can make it" so we dictate the supply & price simply carries on the political BS that's involved in the Oil industry / wars / politics / corruption / pollution... you get the idea.
