Hyundai Motor Group said on Thursday it has completed HTWO Energy, South Korea's
first facility producing clean hydrogen from biogas extracted from sewage
sludge. Located inside a municipal wastewater treatment plant in Cheongju, about
137 km south of Seoul, the 7,500 sqm site has an initial daily hydrogen output
of about 500 kg — enough to refuel roughly 100 Hyundai Nexo fuel‑cell cars or 30
fuel‑cell buses. The plant includes biogas upgrading to biomethane,
steam‑reforming of biomethane to hydrogen and a liquid CO2 production unit.
Hyundai plans to raise the facility's average daily hydrogen capacity to 2
tons by 2030.
