I found it very interesting when one person who was being interviewed talked about an advance of FCEVs over BEVs was when refueling at night when the sun is not and “when the wind is not blowing.” I’ve lived in 10 different states and visited all 50 states. It is clear that wind blows both during the night and day. I guess that when an investigation/report is sponsored by Toyota the info presented favors Toyota as much as possible. The lady also failed to truly list the pollution caused by the predominate source of hydrogen for the fuel cell. From what I have read many times over the past few years the majority of hydrogen for fuel cells comes from natural gas. That natural gas is probably extracted from the earth via fracking which is most certainly not earth or people friendly.
