 Today, there aren't many hydrogen vehicles on the road. But Matt Miasato of First Element Fuel says that's going to change. So in 2036, every light-duty vehicle sold and every truck sold in California has to be zero emissions. We anticipate a large portion of those are going to be battery, but also a significant portion will be fuel cells, just because the grid can't handle that type of charging infrastructure. And we think we've cracked that nut in terms of how to solve refueling for hydrogen.
