Inside the S2H2 Project: 25 Tonnes a Day, 1 Tonne of Hydrogen
A look at the engineering challenges of scaling sewage sludge processing to industrial volumes.
The S2H2 project — backed by the EU Innovation Fund — is our largest single deployment to date. The target: 25 tonnes of dried sewage sludge per day, yielding approximately 1 tonne of hydrogen.
Why sludge?
Every European wastewater treatment plant has to dispose of sludge. It is wet, energy-intensive to incinerate, and rarely valorised. Yet it is also a remarkably consistent thermochemical feedstock.
The engineering challenges
Drying, feedstock preparation, syngas conditioning, and downstream hydrogen separation all have to be solved at industrial scale. S2H2 has just completed its engineering design freeze; procurement begins in Q2.
