Hydrogen delivered by pPetual is Carbon Neutral.  It is produced, using 99.99% renewable energy, from an infinitely renewable resource and when used in a fuel cell, produces electricity with zero emissions other than pure fresh water and a little heat.  
Fuel Cells need both pure Hydrogen and ultra clean air.  As a fuel cell takes in air, the air is purified and it emerges many times cleaner than when it went in.
pPetual produces infinitely renewable, sustanable, environmental, CO₂ neutral Hydrogen with zero black carbon emissions
To us, it’s  Emerald Hydrogen™ – eH₂™
