Yes. It's actually quite interesting. I studied that 20 years ago and did quite a bit of work on that.
Hydrogen is actually pulled out of the atmosphere by soil microorganisms. Essentially, the hydrogen exists in only half a part per million in the atmosphere. When you double hydrogen in the atmosphere, the biology of the biological soils around the world will stimulate the microbial activity and pull the hydrogen back out. Effectively, the work that was done 20 years ago suggested that there's certainly very little problem with some hydrogen emissions. The biological systems will self-regulate in feedback.
