I know there was a company targeting supply of electric tractors to farmers, they were partnering with SIRC for the installation of panels and battery storage to allow overnight charging, been quiet for a few months now (lieka lot of SIRC stories)
For larger machines hydrogen is the only answer - as it is in the construction equipment world
Some sort of JV either on the HYVIA or the Gaussin model would make sense. I think partners can see that PLUG is flexible and now can provide even more of the solution for farmers/co-ops etc. (ACT & Frames involvement). You need mobile refuelling for harvesters I would suspect. something ACT can help with
Could be a number of deals are in the pipeline waiting for these 2 deals to close.
