A host recounted test-driving hydrogen fuel cell vehicles fifteen years ago, noting the high-pitched "screaming" noise they produced.

Concerns remain regarding the safety and storage of hydrogen tanks, which require extremely high pressure.

EPA Administrator Michael Regan discusses President Biden's goal to cut greenhouse gas emissions by 50% by 2030. Regan outlines plans to use regulatory pressure to transition traditional internal combustion engine vehicles off the road in favor of electric alternatives.
