One novel spin on emerging hydrogen fuel options is “clean hydrogen” made from trash.
Early pioneers of these hydrogen-from-waste technologies such as Ways2H, SGH2 Energy (SGH2) and Standard Hydrogen say not only are they making carbon-free, energy-rich fuel, their approaches also will divert mountains of trash from landfills and waterways, cutting greenhouse gas emissions.
Green hydrogen — made by splitting water’s hydrogen and oxygen using electricity produced by renewable sources — is a small fish in the “energies pond.” Today, more than 95 percent of hydrogen is fossil-based and does not rely on renewables. Other technologies are in the mix, such as battery electric vehicles.
Hydrogen from waste is an even smaller fish than hydrogen from renewable energy. There are only a few waste-to-hydrogen
