Hyundai Motor Company has announced it will build a hydrogen production facility at a public sewage treatment plant in the Korean city of Cheongju, producing clean H2 from biogas obtained from on-site organic waste.

The car manufacturer says the plant will produce 500kg of clean hydrogen per day “by 2024”, with plans to double the daily production to one tonne by 2027.
“In addition, a hydrogen filling station will be installed nearby to supply clean hydrogen at a reasonable price to local residents,” Hyundai said in a press release, adding that this will be cheaper than locally produced by-product hydrogen.
The hydrogen-from-sewage facility will be built in conjunction with the non-profit Institute for Advanced Engineering after the project was selected in a contest organised by the Ministry of Environment.
Biogas is produced inside huge tanks known as anaerobic digesters, where microorganisms break down organic waste in the absence of oxygen.
