Unless they had insight into the future, Toyota has been exploring this technology a long time[1]. They started a developing fuel cell propulsion in 1992 --way before there was mainstream antipathy for fossil fuels. The more likely explanation is they sought alternative fuels and settled on Hydrogen and so, now, despite evidence and viability of battery electrics, they keep on pushing "their" solution probably with lots of influence from the sunk cost fallacy. [1] Recall "peak oil", before Fracking became viable, was a serious concern since the '70s and people thought fossil fuels would eventually become unaffordable to everyday consumers.
