How the Hy system works:

from waste water to Methane gas

then via fuel cell (Fcel) to Hydrogen gas

The Orange County, CA station uses methane gas from the Orange County Sanitation District's municipal wastewater plant. The methane is funneled into a purification system, where it is fed to a fuel cell and turned into hydrogen. Electricity and heat from the fuel cell is used at the wastewater facility, while excess hydrogen is used at Air Products' filling station. The station can produce enough hydrogen to fuel up to 50 vehicles each day.

Air Products

Hydrogen fueling company Air Products just opened a fueling station that turns methane gas from a local wastewater treatment plant into hydrogen gas that can be used to fill fuel cell vehicles--a first in the hydrogen fuel cell industry.

That may change when the fuel cell vehicle market really starts around 2014, when the cars start rolling off production lines. In 2015, the real test begins: GM plans to build a hydrogen fueling infrastructure for Hawaii. And if Air Products' wastewater fueling station is successful, GM might want to consider adapting the technology in the future.
