S2H2 Reaches Engineering Design Freeze

The S2H2 project has completed its full engineering design freeze, targeting the conversion of 25 tonnes of sewage sludge per day into approximately 1 tonne of hydrogen.

The design package covers feedstock preparation, the thermochemical reactor, syngas conditioning, and downstream hydrogen separation. Procurement begins in Q2 with construction targeted for late 2026.

S2H2 is supported by the EU Innovation Fund and represents Indeloop’s largest single-site deployment to date.
