After cleaning, the water is used for irrigation or pumped into the ocean.PowerPoint Presentation: Wearing hard hats provided by OCSD, we hopped on the shuttle bus for our tour behind the fence.PowerPoint Presentation: This is a trickle pond. By the time the water gets here, it’s so clean that many, many ducks call it home.PowerPoint Presentation: Wastewater solids are pumped into digesters where they decompose over about 20 days at temperatures of about 100 degrees. Half the solids are turn into methane, which Fountain Valley plant burns to create electricity. The left over solids are dried in another process and used mostly for fertilizer.PowerPoint Presentation: At OCSD’s new fuel cell system, gas from one digester travels through the silver pipes into a scrubber that removes sulfur and siloxanes , contaminates that are difficult for engines and fuel cells to handle.PowerPoint Presentation: Scrubbed bio-methane enters the FuelCell Energy molten carbonate fuel cell stack, which is the size of a shipping container. An MCFC uses natural gas/bio-methane (CH4) and oxygen (O2) to create H2 and CO2, but it consumes the CO2 in the process.PowerPoint Presentation: The fuel cell produces three things: Electricity, which is fed into OCSD’s grid Hot water, which goes into the digester Hydrogen, which most MCFCs vent into the atmosphere, but not OCSD!PowerPoint Presentation: The OCSD system feeds the hydrogen through one more scrubber to make it fuel-quality and then pumps it into a compressor. These silver pipes hold uncompressed hydrogen. The compressor is out of sight in the center.PowerPoint Presentation: About half the compressed hydrogen is stored in tubes at the fuel cell. More tubes of compressed hydrogen are at the station.PowerPoint Presentation: To get from the back of the facility to the station, compress hydrogen travels through a skinny round pipe inside the square pipe. Why a pipe inside a pipe? Because they already had square mounting brackets.PowerPoint Presentation: After traveling underground for a while, the pipe carrying the hydrogen runs overland attached to the fence. The bottom pipe is H2. The top pipe is natural gas for the CNG dispenser. (Regular CNG, not bio-methane.)PowerPoint Presentation: Our tour guide, Roxy, shows off the dispenser. Roxy is a grad student at UC Irvine, which is a partner in the OCSD station project.PowerPoint Presentation: Group shot of my CHBC tour group at the dispenser.PowerPoint Presentation: Thanks for watching CHBC’s tour of the Fountain Valley hydrogen station!
