Wastewater boosts green hydrogen prospects

Using wastewater for hydrogen production could cut water treatment costs by 47%.

Why it matters

  • Wastewater can replace clean water in hydrogen production, cutting costs and improving sustainability.
  • Solves a key issue in hydrogen fuel: clean water dependency.

By the numbers

  • 47% cut in water treatment costs.
  • 62% drop in energy costs for water treatment.
  • System lasts over 300 hours without issues.

The big picture

  • Green hydrogen can decarbonize industries like steel and fertilizer.
  • Wastewater plants offer a widespread water source for hydrogen.

What they're saying

  • Study published in Water Research (Sept. 24).
  • Industry testing underway for larger-scale use.

Caveats

  • Research in testing phase; real-world results may vary.

What’s next

  • Scaling up with industry partners.
  • Exploring pretreated seawater for hydrogen production.
