JCB probably need a differentiator to make their product stand out and for potentially selfish reasons, a hydrogen burning engine is likely to be easier to integrate in to their existing equipment.
Hydraulic fluid is pumped so I guess an electric pump would do it.
I guess, the cost of hydrogen burning engines are going to be a lot cheaper than a huge capacity battery pack. I wish I could see a Perkins Engines price list.
I wonder if hydraulic systems would be needed given the potential torque of electric motors?
Stick a motor on each moving component / joint and wire it up and that might be a solution - the machines would probably look fuggly though.
I was looking at the forward order book of some of my clients in the JCB component supply chain just last week and didn't see any material changes over the next 6 months.
