This summer I interviewed Kristie Boering, a professor of atmospheric chemistry at UC Berkeley. We talked about the potential environmental side effects of moving to a hydrogen economy. Our discussion, boiled down to about 800 words, is in the current issue of California magazine. Boering is incredibly articulate, and I learned a lot in the process.
If we were to go to a hydrogen fuel cell economy and we produce a lot of hydrogen, and some fraction escapes (because it’s notoriously difficult to contain that small molecule), then we might see emissions equal to or greater than what’s produced naturally. Because it’s such a reactive gas…that could change the balance of chemistry in our atmosphere.
