Chapter 00 — Feedstock · Refinery residue
Trial-validatedOil Sludge. A hazardous liability turned into the highest-yield stream we run.
Tank-bottom oil sludge is a listed hazardous waste that refineries pay to landfill or incinerate. Its energy density makes it the highest hydrogen-yielding feedstock in our trials. Sited refinery-adjacent, an Ardana plant converts a disposal cost into a hydrogen revenue stream — and destroys the hazard safely in the process.

Why Plasma Gasification Fits
- Exceptional energy density drives the highest hydrogen yield of any feedstock we run.
- Molecular decomposition safely destroys a listed hazardous waste — no open flame.
- Refinery-adjacent siting removes hazardous-material transport risk and cost.
- Converts a per-tonne disposal liability into a hydrogen revenue stream.
- Supports refinery and sovereign net-zero mandates with on-site decarbonisation.
